CROSS REFERENCE TO RELATED APPLICATION 
       [0001]    The present application claims the benefit of the earlier filing date of U.S. Provisional Patent Application Ser. No. 61/443,397 filed on Feb. 16, 2011, the entire contents of which is incorporated herein by reference. 
     
    
     BACKGROUND OF THE DISCLOSURE 
       [0002]    1. Field of the Disclosure 
         [0003]    The present disclosure relates to a variable display scale control device and a variable playing speed control device that are favorably applied to electronic equipment such as a cellular phone, PHS telephone (PHS: Personal Handyphone System), PDA device (PDA: Personal Digital Assistant), digital camera device, digital video camera device, portable gaming device, notebook-type or desktop-type personal computer device, or the like, for example. 
         [0004]    In particular, the present disclosure relates to a variable display scale control device favorably applied to electronic equipment provided with variable operation functionality for predetermined operations, such as variable operations for display scale of display images such as still images and Web browsing images or the like (enlarging operations or reducing operations), and variable operations for playing speed of music data of moving picture data that is played based on a moving picture program or the like. 
         [0005]    2. Description of Related Art 
         [0006]    The applicant of the present disclosure has obtained the image display method disclosed in Japanese Unexamined Patent Application Publication No. “Japanese Unexamined Patent Application Publication No. 2001-249653” (PTL 1), by researching the prior arts relating to the present disclosure. 
         [0007]    The image display method disclosed in this PTL 1 stores a file group of map data in a memory card, hierarchically and by scale. A mapping memory card is attached to an electronic camera having a map display function, and the camera is set to map display mode, whereby the necessary map data is read from the memory card to an image memory, and the map is displayed on a liquid crystal monitor. 
         [0008]    The image memory has a buffer region for an enlarging/reducing direction and a scrolling direction. Upon an operator continuously performing enlarging operations or scrolling operations, a system controller detects the continuous nature of the operation, and before the display on the display area begins, starts processing to read in the map data in advance that is included in the buffer region. Operations are performed such that, when the display of the display area thereof begins, the read-in processing is already completed. 
         [0009]    Thus, discontinuance of the display operation that happens with screen enlarging/reducing or scrolling operations is avoided, and operability can be improved. 
       SUMMARY OF THE DISCLOSURE 
       [0010]    Accordingly, in the case of performing enlarging operations or reducing operations of still images, objects, and the like that are displayed on the display unit, there is a problem in that the display scale differs from the desired display scale due to minor operational errors. 
         [0011]    Also, similarly with music players and moving picture players, subtle operations for the content playing speed is difficult, whereby in the case of adjusting the playing speed to the desired playing speed, there has been a problem in that the playing speed differs from the desired playing speed due to minor operational errors. 
         [0012]    The inventor of the present disclosure recognizes the need to provide a variable display scale control device having operations that can easily change the display scale of an object to a display scale that has a high probability of what the operator desires, and a variable playing speed control device having operations that can easily change the playing speed of content to a playing speed that has a high probability of what the operator desires. 
         [0013]    One embodiment of the disclosure is directed to an information processing apparatus, method, and computer-readable medium that includes displaying, by an interface of the information processing apparatus, an object; receiving, by the interface, an instruction to change a display scale of the object; and controlling, by a processor of the information processing apparatus, the interface to change the display scale of the object based on the received instruction, to stop changing the display scale of the displayed object for a predetermined period of time when the display scale of the displayed object becomes a predetermined display scale, and to resume changing the display scale of the displayed object upon determining that the predetermined period of time has elapsed. 
         [0014]    According to another exemplary embodiment, the disclosure is directed to an information processing apparatus, method, and computer-readable medium that includes reproducing content by a reproduction section of the information processing apparatus; receiving, by an interface of the information processing apparatus, an instruction to change a reproduction speed of the content; and controlling, by a processor of the information processing apparatus, the reproduction section to change the reproduction speed of the content based on the received instruction, to stop changing the reproduction speed of the content for a predetermined period of time when the reproduction speed of the content becomes a predetermined reproduction speed, and to resume changing the reproduction speed of the content upon determining that the predetermined period of time has elapsed.

         [0070]    Note that the camera control program, email managing program, schedule book managing program, Web browsing program, and music player program and the like may be provided as various programs to the cellular phone by installing the memory  14  wherein these various programs are stored therein beforehand. 
         [0071]    Alternatively, the various programs may be provided to the cellular phone by storing the various programs downloaded via a network in the memory  14 . 
         [0072]    Alternatively, the various programs may be provided to the cellular phone by storing the various programs read in from an external memory in the memory  14 . 
         [0073]    The cellular phone according to an embodiment can, in the event of performing enlarging operations of a still image, easily perform enlarging operations of still images to an enlargement scale having a high probability of being desired by the operator. 
         [0074]      FIG. 2  is a flowchart showing the flow of enlarging processing of a still image with the control unit  15  of the cellular phone. The control unit  15 , upon the operator performing display specifying operations, performs display control of the still image specified by the operation to display of the display unit  5 , based on the viewer program of the camera control program stored in the memory  14 . The control unit  15  monitors whether or not there has been any enlarging processing operations of the still image at a timing wherein the still image is controlled to display on the display unit  5 , and upon detecting enlarging processing operations, the processing shown in the flowchart in  FIG. 2  is started, based on the viewer program of the camera control program. 
         [0075]    Specifically, in the case of the cellular phone according to the present embodiment, of the examples of “dragging operations”, “flicking operations”, and “long-pressing operations”, by performing one of these operations, the still image displayed on the display unit  5  can be subjected to enlarging operations. 
         [0076]    The dragging operation is an operation wherein the operator touches the display unit with a finger, and slides this touched finger in the upper direction while in the state of touching the display unit  5 . The control unit  15  detects the distance between the position wherein the finger of the operator is touching the display unit  5  which serves as a touch panel and the position wherein the finger that has been sliding is removed from the display unit  5  at the touching position (the distance of the series of dragging operations), and subjects the still image displayed on the display unit  5  to enlarging operation according to the dragging operation distance and displays this. 
         [0077]    Also, the flicking operation is an operation wherein the operator touches the display unit  5  with a finger, and flicks this touched finger in the upper direction while in the state of touching the display unit  5 . The control unit  15  detects the distance between the position wherein the finger of the operator is touching the display unit  5  which serves as a touch panel and the position wherein the finger that is flicking is removed from the display unit  5  at the touching position (the distance of the series of flicking operations), and subjects the still image displayed on the display unit  5  to enlarging operation according to the flicking operation distance and displays this. 
         [0078]    Also, the long-pressing operation is an operation wherein the operator lightly continues to press the display unit  5  with a finger. The control unit  15  detects the time from when the finger of the operator touches the display unit  5  serving until the finger is released (the time of the series of long-pressing), and displays the still image displayed on the display unit  5  by enlarging processing according to the long-pressing operation time. 
         [0079]    Note that in this example, in the event of performing enlarging operations of a still image, the descriptions are of performing “dragging operations”, “flicking operation”, or “long-pressing operations”, but instead of these operations, enlarging operations of the still image may be performed with other operations such as a pinching operation or with a hardware key  6  provided on the casing. 
         [0080]    Note that the pinching operation is a operation wherein the thumb and index finger in a state of contact with one another each touch the touch panel, maintain the state of each finger touching the touch panel, and the thumb and index finger that are in contact with one another are gradually separated. In this case, the control unit  15  performs enlarging processing of still images according to the distance between the thumb and index finger that are separated while in the state of being in contact with the touch panel. 
         [0081]    Upon such an enlarging operation being performed by the operator, in step S 1  the control unit  15  subjects the still image displayed on the display unit  5  to enlarging operations according to the enlarging operation described above, and advances the processing to step S 2 . 
         [0082]    The control unit  15  performs the enlarging processing of the still image according to the series of dragging operations or long-pressing operations as described above. That is to say, the control unit  15  performs the enlarging processing of the still image according to continuous dragging operations or long-pressing operations from the time that the finger of the operator makes contact with the display unit  5  until the finger is released. Therefore, the control unit  15  determines whether or not the enlarging operation is being continuously performed, by detecting in step  2  whether or not there is contact by a user finger as to the display unit  5 . In the case determination is made that the enlarging operation is being continuously performed, the control unit  15  advances the processing to step S 3 . 
         [0083]    Conversely, in the case determination is made that the enlarging operation is not being continuously performed, (i.e. in the case determination is made that the operator finger has been released from the display unit  5 ), the control unit  15  advances the processing to step S 9 , the enlarging processing of the still image is stopped, and the processing shown in the flowchart in  FIG. 2  is ended. 
         [0084]    Next, upon advancing the processing to step S 3  by determining that the enlarging operation is ongoing, the control unit  15  determines whether or not the still image is at a predetermined display scale from the enlarging processing of the still image displayed on the display unit  5 . In the case determination is made that the still image is not at a predetermined display scale, the control unit  15  returns the processing to step S 1 , and continues to perform enlarging processing of the still image. 
         [0085]    Conversely, in the case determination is made that the still image displayed on the display unit  5  is at a predetermined display scale, the processing is advanced to step S 4 , temporarily stops the enlarging processing of the still image at the current display scale, and advances the predetermined to step S 5 . 
         [0086]    In step S 5 , based on the point-in-time information obtained from the timer  10 , the control unit  15  determines whether or not a predetermined amount of time such as 200 msec or 300 msec has elapsed from the time that the enlarging processing of the still image has stopped, and the processing is advanced to step S 6  at a timing that the predetermined amount of time has elapsed. 
         [0087]    In step S 6 , the control unit  15  determines whether or not enlarging operations are being continuously performed, by detecting whether or not the finger of the operator is in contact with the display unit  5 . In the event of determining that the enlarging operations are continuing, the control unit  15  advances the processing to step S 7 . 
         [0088]    Conversely, in the case determination is made in step S 6  that the enlarging operations are not continuing (i.e. in the case determination is made that the finger of the operator has been released from the display unit  5 ), the control unit  15  advances the processing to step S 9 , temporarily stops the enlarging processing of the still image, and ends the processing shown in the flowchart in  FIG. 2 . 
         [0089]    Upon advancing the processing to step S 7  by determining that the enlarging operation is being continuously performed, the control unit  15  resumes the enlarging processing of the still image according to the enlarging operations by the operator, and advances the processing to step S 8 . 
         [0090]    In step S 8 , the control unit  15  determines whether or not the display scale of the still image subjected to enlarging processing is at a maximum display scale. In the case determination is made that the display scale of the still image subjected to enlarging processing is not at the maximum display scale, the control unit  15  performs enlarging processing of the still image during the time that the enlarging operation by the operator is continuously executed and the display scale of the still image is at the maximum display scale. Also, the control unit  15  advances the processing to step S 9  at a timing that the display scale of the still image subjected to enlarging processing reaches the maximum display scale, or at a timing that the series of enlarging operations by the operator has ended, and the control unit  15  stops the enlarging processing and ends the processing shown in the flowchart in  FIG. 2 . 
         [0091]    The enlarging processing of the cellular phone will be described below using specific examples. 
         [0092]      FIG. 3  is a diagram showing a situation wherein the still image displayed on the display unit  5  is subjected to enlarging processing according to a dragging operation and displayed.  FIG. 4(   a ) is a diagram showing the correlation between the distance of the dragging operation and the enlargement scale of the still image. 
         [0093]    As can be seen from  FIG. 4(   a ), in the case of the cellular phone, when the enlargement scale (display scale) of the still image is 1.0 times, regardless of whether a dragging operation is being performed by an operator, the enlarging processing of the still image is stopped for 200 msec for example, and at a timing that the 200 msec have elapsed, the enlarging processing of the still image corresponding to the dragging operation of the operator is performed again. 
         [0094]    That is to say, the enlargement scale of 1.0 of the still image means the original image size of the still image thereof (i.e. the size at the time the still image was shot, without change). If the still image is enlarged more than the 1.0 times, the image quality becomes coarse. Therefore, the operator tends to temporarily stop the enlarging operation at the original size of the still image. This means that many operators desire an enlarging operation of an enlargement scale of 1.0 times. 
         [0095]    Therefore, with the cellular phone according to the present embodiment, for example as shown in  FIG. 3(   a ), the control unit  15  first displays the still image on the display unit  5  at an enlargement scale of 0.8 times, performs enlargement processing of the still image according to the dragging operation, and when the enlargement scale of the still image reaches an enlargement scale of 1.0 times, stops the enlargement processing of the still image for a predetermined amount of time such as 200 msec or the like, regardless of the dragging operation being performed as shown in  FIG. 3(   b ) and  FIG. 3(   c ). The control unit  15  then resumes the enlarging processing of the still image as shown in  FIG. 3(   d ), corresponding to the dragging operations of the operator, after the predetermined amount of time having elapsed. 
         [0096]    Thus, even if the dragging operation is continuously performed, the enlargement scale of the still image is controlled so as to temporarily be stopped at an enlargement scale of 1.0 times, the operator can easily subject the still image to display operations at an enlargement scale of 1.0 times. In other words, a still image having an enlargement scale of 1.0 times, which has a great probability of being the desired scale of the operator, can be easily displayed. 
         [0097]    With the example shown in  FIG. 4(   a ), the enlargement scale of the still image is linearly increased according to the dragging operation of the operator, and in the event of reaching the enlargement scale of 1.0 times, the enlargement processing is stopped for a predetermined amount of time such as 200 msec as mentioned above, and after the predetermined amount of time has elapsed, the enlargement scale of the still image is again linearly increased according to the dragging operations by the operator. 
         [0098]    The enlargement scale of the still image is increased according to the dragging operations of the operator as shown in  FIG. 4(   b ), and when the enlargement scale nears 1.0 times, the width of the enlargement processing is gradually reduced, whereby the enlargement scale reaches 1.0 times following a curve, and in the event of reaching the enlargement scale of 1.0 times, the enlargement processing is stopped for a predetermined amount of time such as 200 msec as shown above. After the predetermined amount of time has elapsed, the enlargement scale of the still image may be increased again following a curve according to the dragging operation by the operator. 
         [0099]    In this case, when the enlargement scale of the still image subjected to enlargement operations nears an enlargement scale of 1.0 times, the enlargement width of the still image becomes smaller and the still image reaches an enlargement scale of 1.0 times as mentioned above, and during the predetermined amount of time such as the 200 msec mentioned above, the enlarging processing is stopped. Therefore, as the enlargement scale of the still image nears the enlargement scale of 1.0 times, the enlargement width gradually becomes smaller, and the enlargement processing eventually stops. Also, in the event that the enlargement processing is resumed after a predetermined amount of time having elapsed, the enlargement width gradually is increased, and eventually the enlargement processing of the still image is performed linearly according to the dragging operations. Therefore, an enlarging processing with natural changes can be shown to the user. 
         [0100]    Note that in the examples shown in  FIG. 3(   a ) through  FIG. 3(   d ) and  FIG. 4(   a ) and  FIG. 4(   b ), the enlargement processing is controlled to stop for a predetermined amount of time in the event that the enlargement scale reaches 1.0 times, but the enlargement scale at which to stop the enlargement processing may be optionally set by the operator or the cellular phone maker, to be other than 1.0 times. 
         [0101]    Also, with the example shown in  FIG. 3(   a ) through  FIG. 3(   d ) and  FIG. 4(   a ) and  FIG. 4(   b ), the enlargement processing is controlled to stop for a predetermined amount of time in the event that the enlargement scale reaches 1.0 times, but the enlargement processing may be stopped for a predetermined amount of time when the enlargement scale reaches 1.0 times and when the enlargement scale reaches 2.0 times, respectively. In other words, the enlargement processing may be controlled to be stopped multiple times at desired timings of the enlargement scale, not only limited to once in the event that the enlargement scale reaches 1.0 times. 
         [0102]    Further, the example as described above is an example in the case of enlargement operations of a still image, but performing reduction operations of a still image will be similar to that described above. That is to say, in the case that dragging operations to specify reduction processing in the event that a still image having a display scale of 2.0 times is displayed, the control unit  14  subjects the still image to gradual reduction according to the dragging operation, and in the event that the display scale of the still image reaches a display scale of 1.0 times, the reduction operation by the operator is cancelled for a predetermined amount of time such as 200 msec or the like for example, and the reduction processing is stopped during the predetermined amount of time. The reduction operation of the still image according to dragging operation by the operator is resumed at a timing when the predetermined amount of time has elapsed. 
         [0103]    Thus, even if continuous dragging operations are performed, the reduction scale of the still image can be controlled to be temporarily stopped at a reduction scale of 1.0 times, for example, whereby the operator can easily operate to display the still image having a reduction scale of 1.0 times. In other words, the still image having a display scale of 1.0 times which has a high probability of being desired by the operator can be easily displayed, and also advantages similar to the above descriptions can be obtained. 
         [0104]    Next,  FIG. 5  is a diagram showing a situation wherein the still image displayed on the display unit  5  is subjected to enlarging processing according to the flicking operations and displayed. Also,  FIG. 6(   a ) shows the correlation between the strength of the flicking operation and the enlargement scale of the still image. 
         [0105]    As can be seen from  FIG. 6(   a ), in the case of the cellular phone, in the case that a strong flicking operation is performed, the still image is subjected to enlarging processing according to the strength of the flicking operation, and in the case that a weak flicking operation is performed, the enlarging processing of the still image is temporarily stopped at the above-described enlargement scale of 1.0 times. 
         [0106]    To detect the strength or weakness of the flicking operation, the control unit  15  computes “operational distance of flicking operation/flicking operation time”, whereby “operational speed of flicking operation” is computed. In the case that the operational speed herein is faster than the predetermined operational speed (i.e. operational speed serving as a threshold), this means that a strong flicking operation is performed, and in the case that the operational speed herein is slower than the predetermined operational speed, this means that a weak flicking operation is performed. 
         [0107]    Therefore, in the case that the control unit  15  detects a strong flicking operation which is a high speed flicking operation, as shown in  FIG. 5(   a ) and  FIG. 6(   a ), the enlargement processing of the still image is not stopped at the enlargement scale of 1.0 times as with the description above, but the still image is subjected to enlargement processing with an enlargement scale corresponding to the strength of the flicking operation, and this is displayed on the display unit  5 . 
         [0108]    Conversely, in the case that the control unit  15  detects a weak flicking operation which is a slow speed flicking operation, as shown in  FIG. 5(   b ) and  FIG. 6(   a ), the enlargement processing of the still image is stopped at the enlargement scale of 1.0 times as with the description above. In the case that a flicking operation is performed again after this stopping, the still image is subjected to enlargement processing with an enlargement scale corresponding to the strength of the flicking operation, and this is displayed on the display unit  5 . 
         [0109]    Thus, when a weak flicking operation is performed, the enlargement scale of the still image is controlled to be temporarily stopped at an enlargement scale of 1.0 times, whereby the operator can easily display the still image having an enlargement scale of 1.0 times. In other words, the still image having a display scale of 1.0 times which has a high probability of being desired by the operator can be easily displayed. 
         [0110]    Note that in the event that the enlargement scale of the still image is gradually increased according to a weak flicking operation by the operator and the enlargement scale nears 1.0 times as shown in  FIG. 4(   b ), the enlargement scale may be caused to reach 1.0 times following a curve by gradually reducing the width of the enlargement processing, and in the event of reaching an enlargement scale of 1.0 times the enlargement processing may be stopped. 
         [0111]    Thus, as the enlargement scale of the still image nears the enlargement scale of 1.0 times, the enlargement width is gradually decreased, and the enlargement processing eventually is stopped, whereby enlargement processing with natural changes can be shown to the user. 
         [0112]    Also, according to the example herein, in the event that the enlargement scale reaches 1.0 times, the enlargement processing is controlled to be stopped, but even if the enlargement scale at which to stop the enlargement processing is other than 1.0 times, this can be set optionally by the operator or the maker of the cellular phone. 
         [0113]    Further, the example as described above is an example in the case of enlargement operations of a still image, but performing reduction operations of a still image will be similar to that described above. That is to say, in the case that weak flicking operations is performed to specify reduction processing in the event that a still image having a display scale of 2.0 times is displayed, the control unit  15  subjects the still image to gradual reduction according to the weak flicking operation, and in the event that the display scale of the still image reaches a display scale of 1.0 times, the reduction operation is stopped. 
         [0114]    Thus, the reduction scale of the still image can be controlled to be temporarily stopped at a reduction scale of 1.0 times, for example, whereby the operator can easily operate to display the still image having a reduction scale of 1.0 times. In other words, the still image having a display scale of 1.0 times which has a high probability of being desired by the operator can be easily displayed, and also advantages similar to the above descriptions can be obtained. 
         [0115]    Next,  FIG. 7(   a ) through  FIG. 7(   d ) are diagrams showing a situation wherein the still image displayed on the display unit  5  is subjected to enlarging processing according to the long-pressing operations and displayed. Also,  FIG. 8(   a ) shows the correlation between the time of the long-pressing operation and the enlargement scale of the still image. 
         [0116]    As can be seen from  FIG. 8(   a ), in the case of the cellular phone, when the enlargement scale (display scale) of the still image subjected to enlarging processing by a long-pressing operation by the operator is 1.0 times, regardless of the long-pressing operation being performed by the operator, the enlarging processing of the still image is stopped for 200 msec for example, and at a timing that the 200 msec have elapsed, the enlarging processing of the still image corresponding to the long-pressing operation of the operator is performed again. 
         [0117]    As shown in  FIG. 7(   a ) for example, the control unit  15  first displays the still image on the display unit  5  at an enlargement scale of 0.8 times, performs enlargement processing of the still image according to the long-pressing operation, and when the enlargement scale of the still image reaches an enlargement scale of 1.0 times, stops the enlargement processing of the still image for a predetermined amount of time such as 200 msec or the like, regardless of the long-pressing operation being performed as shown in  FIG. 7(   b ) and  FIG. 7(   c ). The control unit  15  then resumes the enlarging processing of the still image as shown in  FIG. 7(   d ), corresponding to the long-pressing operations of the operator, after the predetermined amount of time having elapsed. 
         [0118]    Thus, even if the long-pressing operation is continuously performed, the enlargement scale of the still image is controlled so as to temporarily be stopped at an enlargement scale of 1.0 times, the still image can easily be subjected to display operations at an enlargement scale of 1.0 times. In other words, a still image having an enlargement scale of 1.0 times, which has a great probability of being the desired scale of the operator, can be easily displayed. 
         [0119]    With the example shown in  FIG. 8(   a ), the enlargement scale of the still image is linearly increased according to the long-pressing operation of the operator, and in the event of reaching the enlargement scale of 1.0 times, the enlargement processing is stopped for a predetermined amount of time such as 200 msec as mentioned above, and after the predetermined amount of time has elapsed, the enlargement scale of the still image is again linearly increased according to the long-pressing operations by the operator. 
         [0120]    The enlargement scale of the still image is increased according to the long-pressing operations of the operator as shown in  FIG. 8(   b ), and when the enlargement scale nears 1.0 times, the width of the enlargement processing is gradually reduced, whereby the enlargement scale reaches 1.0 times following a curve, and in the event of reaching the enlargement scale of 1.0 times, the enlargement processing is stopped for a predetermined amount of time such as 200 msec as shown above. After the predetermined amount of time has elapsed, the enlargement scale of the still image may be increased again following a curve according to the long-pressing operation by the operator. 
         [0121]    In this case, when the enlargement scale of the still image subjected to long-pressing operations nears an enlargement scale of 1.0 times, the enlargement width of the still image becomes smaller and the still image reaches an enlargement scale of 1.0 times as mentioned above, and during the predetermined amount of time such as the 200 msec mentioned above, the enlarging processing is stopped. Therefore, as the enlargement scale of the still image nears the enlargement scale of 1.0 times, the enlargement width gradually becomes smaller, and the enlargement processing eventually stops. Also, in the event that the enlargement processing is resumed after a predetermined amount of time having elapsed, the enlargement width gradually is increased, and eventually the enlargement processing of the still image is performed linearly according to the long-pressing operations. Therefore, an enlarging processing with natural changes can be shown to the user. 
         [0122]    Note that in the examples shown in  FIG. 7(   a ) through  FIG. 7(   d ) and  FIG. 8(   a ) and  FIG. 8(   b ), the enlargement processing is controlled to stop for a predetermined amount of time in the event that the enlargement scale reaches 1.0 times, but the enlargement scale at which to stop the enlargement processing may be optionally set by the operator or the cellular phone maker, to be other than 1.0 times. 
         [0123]    Also, with the example shown in  FIG. 7(   a ) through  FIG. 7(   d ) and  FIG. 8(   a ) and  FIG. 8(   b ), the enlargement processing is controlled to stop for a predetermined amount of time in the event that the enlargement scale reaches 1.0 times, but the enlargement processing may be stopped for a predetermined amount of time when the enlargement scale reaches 1.0 times and when the enlargement scale reaches 2.0 times, respectively. In other words, the enlargement processing may be controlled to be stopped multiple times at desired timings of the enlargement scale, not only limited to once in the event that the enlargement scale reaches 1.0 times. 
         [0124]    Further, the example as described above is an example in the case of enlargement operations of a still image, but performing reduction operations of a still image will be similar to that described above. 
         [0125]    That is to say, in the case that long-pressing operations to specify reduction processing in the event that a still image having a display scale of 2.0 times is displayed, the control unit  15  subjects the still image to gradual reduction according to the long-pressing operation, and in the event that the display scale of the still image reaches a display scale of 1.0 times, the long-pressing operation performed by the operator is ignored (canceled), and the reduction processing is stopped during the predetermined amount of time. The reduction operation of the still image according to long-pressing operation by the operator is resumed at a timing when the predetermined amount of time has elapsed. 
         [0126]    Thus, even if continuous long-pressing operations are performed, the reduction scale of the still image can be controlled to be temporarily stopped at a reduction scale of 1.0 times, for example, whereby the operator can easily operate to display the still image having a reduction scale of 1.0 times. In other words, the still image having a display scale of 1.0 times which has a high probability of being desired by the operator can be easily displayed, and also advantages similar to the above descriptions can be obtained. 
         [0127]    Next, the above-described example described temporarily stopping the enlargement processing of the still image in the event that the enlargement scale of the still image reaching 1.0 times. In the case that a facial image of a person is showing in the still image, as described below, the enlargement processing of the still image can be temporarily stopped at a timing that the facial image is fully enlarged on the display screen. 
         [0128]    The flowchart in  FIG. 9  shows the flow of the enlargement processing in the case that only one facial image of a person is showing in the still image to be subjected to enlarging processing. Upon controlling the still image specified by the operator to be displayed on the display unit  5  based on the viewer program of the camera control program, the processing shown in the flowchart in  FIG. 9  is started based on the viewer program herein. 
         [0129]    In step S 11 , the control unit  15  determines whether or not a facial image of a person is currently showing in the still image displayed on the display unit  5 , based on a face recognition program built into the camera control program. In the case determination is made that there is no facial image of a person in the still image, the processing is advanced to step S 1  in the flowchart in  FIG. 2 , and in the event that the enlargement scale reaches 1.0 times as described above, control is performed to temporarily stop the enlargement processing. 
         [0130]    Conversely, in the case determination is made that this is a facial image of a person in the still image, the control unit  15  advances the processing to step S 12 , and determines whether or not multiple facial images of persons are currently showing in the still image displayed on the display unit  5 . In the case determination is made in step S 12  herein that multiple facial images of persons are showing in the still image, the processing is advanced to step S 31  in the flowchart in  FIG. 10  to be described later. 
         [0131]    Conversely, determining in step S 12  that multiple facial images of persons are not showing in the still image means that only one facial image of a person is showing in the still image, whereby the control unit  15  advances the processing to step S 13 . 
         [0132]    In step S 13 , the control unit  15  monitors the operational situation of the display unit  5 , thereby monitoring whether or not enlarging operations such as the above-described dragging operations, long-pressing operations or the like are performed, and advances processing to step S 14  at a timing that a enlarging operation is detected. 
         [0133]    In step S 14 , the control unit  15  subjects the still image to enlarging processing according to the enlarging operations of the operator and displays this on the display unit  5 , and advances the processing to step S 15 . In step S 15 , the control unit  15  determines whether or not one of the outline portions of a facial image subjected to enlarging processing has been displayed at an end portion of the display unit  5 , based on the face recognition program. 
         [0134]    That is to say, in step S 14 , the control unit  15  performs enlarging processing of the still image, thereby determining whether or not the enlarging processing of the still image has been performed until one of the portions of an outline of the facial image has reached an edge portion of the display unit  5 . 
         [0135]    In the case determination is made that one of the portions of an outline of the facial image has not reached an edge portion of the display unit  5 , the control unit  15  advances the processing to step S 22  and monitors whether or not the operator is continuing the enlarging operations. The control unit  15  then performs enlarging processing of the still image (step S 14 ) during the time that enlarging operations are continued by the operator (step S 22 ) and until one of the portions of an outline of the facial image has reached an edge portion of the display unit  5  (step S 15 ). In step S 15 , the control unit  15  advances the processing to step S 16  at a timing that one of the portions of an outline of the facial image has been determined to have reached an edge portion of the display unit  5 . 
         [0136]    In step S 16 , one of the portions of an outline of the facial image has reached an edge portion of the display unit  5 , whereby the control unit  15  temporarily stops the enlarging processing of the still image with the current display scale, and advances the processing to step S 17 . In step S 17 , upon temporarily stopping the enlarging processing of the still image, determination is made as to whether or not a predetermined amount of time such as 200 msec for example has elapsed, and the processing is advanced to step S 18  at the timing that the predetermined amount of time has been determined to have elapsed. 
         [0137]    That is to say, in the case of this example, by performing the enlarging processing of the still image, in the event of displaying one of the portions of an outline of the facial image showing in the still image on the display unit  5 , even if the enlarging operations are being continuously performed by the operator, the control unit  15  cancels the enlarging operation and stops the enlarging processing of the still image for a predetermined amount of time. 
         [0138]    Upon stopping the enlarging processing of the still image for a predetermined amount of time, the control unit  15  advances the processing to step S 18 , determines whether or not the enlarging operations are continuously performed by the operator, and in the case the enlarging operations are not continuously performed by the operator, the processing shown in the flowchart in  FIG. 9  is ended with no further processing. 
         [0139]    Conversely, in the case determination is made in step s 18  that enlarging operations are continuously performed by the operator, the control unit  15  advances the processing to step S 19 . In step S 19 , the control unit  15  resumes the enlarging processing of the still image according to enlarging operations by the operator, and advances the processing to step S 20 . 
         [0140]    In step S 20 , the control unit  15  determines with the resumed enlarging processing whether or not the display scale of the still image has reached the maximum display scale. Upon resuming the enlarging processing of the still image, the control unit  15  performs monitoring of whether or not enlarging operations are continuously performed by the operator (step S 18 ) and monitoring of whether or not the display scale of the still image has reached the maximum display scale (step S 20 ). In the case that the operator has ended the enlarging operation before the display scale of the still image reaches the maximum display scale, the control unit  15  ends the processing in the flowchart in  FIG. 9  with no further processing. Also, even if before the operator ends the enlarging operations, in the case the display scale of the still image reaches the maximum display scale, the control unit  15  advances the processing from step S 20  to step S 21 , stops the enlarging processing of the still image, and ends the processing in the flowchart in  FIG. 9 . 
         [0141]    In the case of this example, upon recognizing that only one facial image of a person is showing in the still image, the control unit  15  subjects the still image to enlarging processing according to the enlarging operations by the operator, cancels the enlarging operation by the operator at a timing that one of the portions of an outline of the facial image showing in the still image subjected to enlarging processing reaches an edge portion of the display unit  5 , and stops the enlarging processing for a predetermined amount of time. The control unit  15  then resumes the enlarging processing of the still image according to the enlarging operations by the operator after the predetermined amount of time has elapsed, and in the event that the display scale of the still image has reached the maximum display scale, the control unit  15  stops the enlarging processing of the still image. 
         [0142]    Thus, in a case wherein only one facial image of a person is showing in a still image, the enlarging processing can be temporarily stopped at a timing that the outline of the facial image reaches the edge portions of the display unit  5 . In the state that the outline of the facial image has reached the edge portions of the display unit  5 , this means that the facial image is in a state of having been fully displayed as to the display unit  5 . 
         [0143]    Also, in a state that the facial image is fully displayed as to the display unit  5 , there is a great probability that the display scale is that which the operator performing the enlarging operations of the still image desires. Therefore, by temporarily stopping the enlarging processing at a timing that the outline of the facial image has reached the edge portions of the display unit  5 , the display scale of the still image can be easily operated to change to the display scale desired by the operator. 
         [0144]    Next, the example described above is of a flow of enlarging processing in the case that only one facial image of a person is showing in the still image, but the enlarging processing in the case that multiple facial images of persons are shown in the still image is as the flow in the flowchart in  FIG. 10 . 
         [0145]    That is to say, in step S 12  in the flowchart in  FIG. 9 , upon determining that currently multiple facial images of persons are showing in the still image displayed on the display unit  5 , the control unit  15  advances the processing to step S 31  in the flowchart in  FIG. 10 . 
         [0146]    In step S 31 , the control unit  15  monitors the operational state of the display unit  5 , thereby monitoring whether or not there are any enlarging operations such as the above-described dragging operations or long-pressing operations, and advances the processing to step S 32  at the timing that the enlarging operation is detected. 
         [0147]    In step s 32 , the control unit  15  subjects the still image to enlarging processing according to the enlarging operations by the operator and displays this on the display unit  5 , and advances the processing to step S 33 . In step S 33 , the control unit  15  determines whether or not one of the outline portions of one of the facial images out of the multiple facial images subjected to enlarging processing is to be displayed at an edge portion of the display unit  5 , based on the face recognition program. 
         [0148]    That is to say, in step S 33 , by performing the enlarging processing of the still image, the control unit  15  determines whether or not an outline portion of one of the facial images out of the multiple facial images shown in the still image has reached an edge portion of the display unit  5 . 
         [0149]    In the case determination is made that outlines in all of the facial images have not reached an edge portion of the display unit  5 , the control unit  15  advances the processing to step S 42 , and monitors whether or not the operator is continuing the enlarging operations. The control unit  15  then performs enlarging processing of the still image (step S 32 ) during the time that enlarging operations are continued by the operator (step S 42 ) and until one of the portions of an outline of the facial image has reached an edge portion of the display unit  5  (step S 33 ). In step S 33 , the control unit  15  advances the processing to step S 34  at a timing that one of the portions of an outline of the facial image has been determined to have reached an edge portion of the display unit  5 . 
         [0150]    In step S 34 , one of the portions of an outline of one of the facial images has reached an edge portion of the display unit  5 , whereby the control unit  15  temporarily stops the enlarging processing of the still image with the current display scale, and advances the processing to step S 35 . In step S 35 , upon temporarily stopping the enlarging processing of the still image, determination is made as to whether or not a predetermined amount of time such as 200 msec for example has elapsed, and the processing is advanced to step S 36  at the timing that the predetermined amount of time has been determined to have elapsed. 
         [0151]    That is to say, in the case of this example, by performing the enlarging processing of the still image, in the event of displaying one of the portions of an outline of one of the facial images showing in the still image on the display unit  5 , even if the enlarging operations are being continuously performed by the operator, the control unit  15  cancels the enlarging operation and stops the enlarging processing of the still image for a predetermined amount of time. 
         [0152]    Upon stopping the enlarging processing of the still image for a predetermined amount of time, the control unit  15  advances the processing to step S 36 , determines whether or not the enlarging operations are continuously performed by the operator, and in the case the enlarging operations are not continuously performed by the operator, the processing shown in the flowchart in  FIG. 10  is ended with no further processing. 
         [0153]    Conversely, in the case determination is made in step S 36  that enlarging operations are continuously performed by the operator, the control unit  15  advances the processing to step S 37 . In step S 37 , the control unit  15  resumes the enlarging processing of the still image according to enlarging operations by the operator, and advances the processing to step S 38 . 
         [0154]    In step S 38 , the control unit  15  determines with the resumed enlarging processing whether or not the outline portion of one of the other facial images, out of the multiple facial images shown in the still image, has reached an edge portion of the display unit  5 . Specifically, for example, in the case that the facial images of Mr. A and Mr. B are shown in the still image, and determination is made in step S 33  that the outline of the facial image of Mr. A has first reached an edge portion of the display unit  5 , in step S 38  herein the control unit  15  determines whether or not the outline of the facial image of Mr. B has reached an edge portion of the display unit  5 . 
         [0155]    In step S 38 , in the case determination is made from the resumed enlarging processing that the outline portion of one of the other facial images, out of the multiple facial images shown in the still image, has not reached an edge portion of the display unit  5 , the control unit  15  performs monitoring in step S 39  of whether or not enlarging operations are continuously performed by the operator and monitoring in step S 40  of whether or not the display scale of the still image has reached the maximum display scale. 
         [0156]    In the case that the operator has ended the enlarging operation before the display scale of the still image reaches the maximum display scale, the control unit  15  ends the processing in the flowchart in  FIG. 10  with no further processing. Also, even if before the operator ends the enlarging operations, in the case the display scale of the still image reaches the maximum display scale, the control unit  15  advances the processing from step S 40  to step S 41 , stops the enlarging processing of the still image, and ends the processing in the flowchart in  FIG. 10 . 
         [0157]    On the other hand, in the case determination is made in step S 38  from the resumed enlarging processing that the outline portion of one of the other facial images, out of the multiple facial images shown in the still image, has reached an edge portion of the display unit  5 , the control unit  15  returns the processing to step S 34 , stops the enlarging processing of the still image at the current display scale again, and advances the processing to step S 35 . In step S 35 , determination is made as to whether or not predetermined amount of time has elapsed from the stopping again, and at a timing that the predetermined time has been determined to have elapsed, the enlarging processing of the still images are resumed as described above. 
         [0158]    In the case of this example, the control unit  15  subjects the still image to enlarging processing according to the enlarging operations by the operator, cancels the enlarging operation by the operator at a timing that one of the portions of an outline of the facial image showing in the still image subjected to enlarging processing reaches an edge portion of the display unit  5 , and stops the enlarging processing for a predetermined amount of time. After the predetermined amount of time has elapsed, the enlarging operations by the operator are cancelled at a timing that one of the portions of an outline of another facial image shown in the still image has reached an edge portion of the display unit  5 , and the enlarging processing by the operator is stopped for a predetermined amount of time. 
         [0159]    Thus, in a case wherein multiple facial images of persons are showing in a still image, the enlarging processing can be temporarily stopped each time that a portion of an outline of the various facial images reaches an edge portion of the display unit  5 . As described above, in the state that the outline of the facial image has reached the edge portions of the display unit  5 , this means that the facial image is in a state of having been fully displayed as to the display unit  5 . Also, it is highly probable that a state in which the facial image is displayed filling up the display unit  5  is at the display scale that the operator who is performing enlarging operations of the still image desires. Therefore, by temporarily stopping the enlarging processing at a timing that the outline of the facial image has reached the edge portion of the display unit  5 , the display scale of the still image can be easily operated to change to the display scale that the operator desires. 
         [0160]    Next, the above-described example has described the enlarging processing of a still image based on a viewer program of a camera control program, but the cellular phone according to the present embodiment has a display scale change control function in the Web browsing program, similar to the above description. The control unit  15  can control to change the display scale of an object displayed on the display unit  5  according to display scale change operations by an operator, based on the Web browsing program herein. 
         [0161]      FIG. 11  is a diagram showing a situation wherein the object displayed on the display unit  5  by the control unit  15  based on the Web browsing program is subjected to enlarging processing according to a dragging operation and displayed.  FIG. 12(   a ) is a diagram showing the correlation between the distance of the dragging operation and the enlargement scale of the object. 
         [0162]    As can be seen from  FIG. 12(   a ), in the case of the cellular phone, when the enlargement scale (display scale) of the object is 1.0 times, regardless of whether a dragging operation is being performed by an operator, the enlarging processing of the still image is stopped for 200 msec for example, and at a timing that the 200 msec have elapsed, the enlarging processing of the still image corresponding to the dragging operation of the operator is performed again. 
         [0163]    That is to say, the enlargement scale of 1.0 of the still image means the original image size of the object thereof (i.e. the size at the time the still image was shot, without change). If the still image is enlarged more than the 1.0 times, the image quality becomes coarse. Therefore, the operator tends to temporarily stop the enlarging operation at the original size of the object. This means that many operators desire an enlarging operation of an enlargement scale of 1.0 times. 
         [0164]    Therefore, with the cellular phone according to the present embodiment, for example as shown in  FIG. 11(   a ), the control unit  15  first displays the object on the display unit  5  at an enlargement scale of 0.8 times, performs enlargement processing of the object according to the dragging operation, and when the enlargement scale of the still image reaches an enlargement scale of 1.0 times, stops the enlargement processing of the object for a predetermined amount of time such as 200 msec or the like, regardless of the dragging operation being performed as shown in  FIG. 11(   b ) and  FIG. 11(   c ). The control unit  15  then resumes the enlarging processing of the object as shown in  FIG. 11(   d ), corresponding to the dragging operations of the operator, after the predetermined amount of time having elapsed. 
         [0165]    Thus, even if the dragging operation is continuously performed, the enlargement scale of the object is controlled so as to temporarily be stopped at an enlargement scale of 1.0 times, object image can easily be subjected to display operations at an enlargement scale of 1.0 times. In other words, an object having an enlargement scale of 1.0 times, which has a great probability of being the desired scale of the operator, can be easily displayed. 
         [0166]    With the example shown in  FIG. 12(   a ), the enlargement scale of the object is linearly increased according to the dragging operation of the operator, and in the event of reaching the enlargement scale of 1.0 times, the enlargement processing is stopped for a predetermined amount of time such as 200 msec as mentioned above, and after the predetermined amount of time has elapsed, the enlargement scale of the object is again linearly increased according to the dragging operations by the operator. 
         [0167]    The enlargement scale of the object is increased according to the dragging operations of the operator as shown in  FIG. 12(   b ), and when the enlargement scale nears 1.0 times, the width of the enlargement processing is gradually reduced, whereby the enlargement scale reaches 1.0 times following a curve, and in the event of reaching the enlargement scale of 1.0 times, the enlargement processing is stopped for a predetermined amount of time such as 200 msec as shown above. After the predetermined amount of time has elapsed, the enlargement scale of the object may be increased again following a curve according to the dragging operation by the operator. 
         [0168]    In this case, when the enlargement scale of the object subjected to enlargement operations nears an enlargement scale of 1.0 times, the enlargement width of the object becomes smaller and the object reaches an enlargement scale of 1.0 times as mentioned above, and during the predetermined amount of time such as the 200 msec mentioned above, the enlarging processing is stopped. Therefore, as the enlargement scale of the object nears the enlargement scale of 1.0 times, the enlargement width gradually becomes smaller, and the enlargement processing eventually stops. Also, in the event that the enlargement processing is resumed after a predetermined amount of time having elapsed, the enlargement width gradually is increased, and eventually the enlargement processing of the object is performed linearly according to the dragging operations. Therefore, an enlarging processing with natural changes can be shown to the user. 
         [0169]    Note that in the examples shown in  FIG. 11(   a ) through  FIG. 11(   d ) and  FIG. 12(   a ) and  FIG. 12(   b ), the enlargement processing is controlled to stop for a predetermined amount of time in the event that the enlargement scale reaches 1.0 times, but the enlargement scale at which to stop the enlargement processing may be optionally set by the operator or the cellular phone maker, to be other than 1.0 times. 
         [0170]    Also, with the example shown in  FIG. 11(   a ) through  FIG. 11(   d ) and  FIG. 12(   a ) and  FIG. 12(   b ), the enlargement processing is controlled to stop for a predetermined amount of time in the event that the enlargement scale reaches 1.0 times, but the enlargement processing may be stopped for a predetermined amount of time when the enlargement scale reaches 1.0 times and when the enlargement scale reaches 2.0 times, respectively. In other words, the enlargement processing may be controlled to be stopped multiple times at desired timings of the enlargement scale, not only limited to once in the event that the enlargement scale reaches 1.0 times. 
         [0171]    Further, the example as described above is an example in the case of enlargement operations of an object, but performing reduction operations of an object will be similar to that described above. That is to say, in the case that dragging operations to specify reduction processing in the event that an object having a display scale of 2.0 times is displayed, the control unit  15  subjects the object to gradual reduction according to the dragging operation, and in the event that the display scale of the object reaches a display scale of 1.0 times, the reduction operation by the operator is cancelled for a predetermined amount of time such as 200 msec or the like for example, and the reduction processing is stopped during the predetermined amount of time. The reduction operation of the object according to dragging operation by the operator is resumed at a timing when the predetermined amount of time has elapsed. 
         [0172]    Thus, even if continuous dragging operations are performed, the reduction scale of the object can be controlled to be temporarily stopped at a reduction scale of 1.0 times, for example, whereby the operator can easily operate to display the object having a reduction scale of 1.0 times. In other words, the object having a display scale of 1.0 times which has a high probability of being desired by the operator can be easily displayed, and also advantages similar to the above descriptions can be obtained. 
         [0173]    Next,  FIG. 13(   a ) and  FIG. 13(   b ) are diagrams showing a situation wherein the object displayed on the display unit  5  based on a Web browsing program is subjected to enlarging processing according to the flicking operations and displayed. Also,  FIG. 14(   a ) shows the correlation between the strength of the flicking operation and the enlargement scale of the still image. 
         [0174]    As can be seen from  FIG. 14(   a ), in the case of the cellular phone, in the case that a strong flicking operation is performed, the object is subjected to enlarging processing according to the strength of the flicking operation, and in the case that a weak flicking operation is performed, the enlarging processing of the object is temporarily stopped at the above-described enlargement scale of 1.0 times. 
         [0175]    To detect the strength or weakness of the flicking operation, the control unit  15  computes “operational distance of flicking operation/flicking operation time”, whereby “operational speed of flicking operation” is computed. In the case that the operational speed herein is faster than the predetermined operational speed (i.e. operational speed serving as a threshold), this means that a strong flicking operation is performed, and in the case that the operational speed herein is slower than the predetermined operational speed, this means that a weak flicking operation is performed. 
         [0176]    Therefore, in the case that the control unit  15  detects a strong flicking operation which is a high speed flicking operation, as shown in  FIG. 13(   a ) and  FIG. 14(   a ), the enlargement processing of the object is not stopped at the enlargement scale of 1.0 times as with the description above, but the object is subjected to enlargement processing with an enlargement scale corresponding to the strength of the flicking operation, and this is displayed on the display unit  5 . 
         [0177]    Conversely, in the case that the control unit  15  detects a weak flicking operation which is a slow speed flicking operation, as shown in  FIG. 13(   a ) and  FIG. 14(   a ), the enlargement processing of the object is stopped at the enlargement scale of 1.0 times as with the description above. In the case that a flicking operation is performed again after this stopping, the object is subjected to enlargement processing with an enlargement scale corresponding to the strength of the flicking operation, and this is displayed on the display unit  5 . 
         [0178]    Thus, when a weak flicking operation is performed, the enlargement scale of the object is controlled to be temporarily stopped at an enlargement scale of 1.0 times, whereby the operator can easily display the object having an enlargement scale of 1.0 times. In other words, the object having a display scale of 1.0 times which has a high probability of being desired by the operator can be easily displayed. 
         [0179]    Note that in the event that the enlargement scale of the object is gradually increased according to a weak flicking operation by the operator and the enlargement scale nears 1.0 times as shown in  FIG. 14(   b ), the enlargement scale may be caused to reach 1.0 times following a curve by gradually reducing the width of the enlargement processing, and in the event of reaching an enlargement scale of 1.0 times the enlargement processing may be stopped. 
         [0180]    Thus, as the enlargement scale of the object nears the enlargement scale of 1.0 times, the enlargement width is gradually decreased, and the enlargement processing eventually is stopped, whereby enlargement processing with natural changes can be shown to the user. 
         [0181]    Also, according to the example herein, in the event that the enlargement scale reaches 1.0 times, the enlargement processing is controlled to be stopped, but even if the enlargement scale at which to stop the enlargement processing is other than 1.0 times, this can be set optionally by the operator or the maker of the cellular phone. 
         [0182]    Further, the example as described above is an example in the case of enlargement operations of an object, but performing reduction operations of an object will be similar to that described above. That is to say, in the case that weak flicking operations is performed to specify reduction processing in the event that an object having a display scale of 2.0 times is displayed, the control unit  15  subjects the object to gradual reduction according to the weak flicking operation, and in the event that the display scale of the object reaches a display scale of 1.0 times, the reduction operation is stopped. 
         [0183]    Thus, the reduction scale of the object can be controlled to be temporarily stopped at a reduction scale of 1.0 times, for example, whereby the operator can easily operate to display the object having a reduction scale of 1.0 times. In other words, the object having a display scale of 1.0 times which has a high probability of being desired by the operator can be easily displayed, and also advantages similar to the above descriptions can be obtained. 
         [0184]    Next,  FIG. 15(   a ) through  FIG. 15(   d ) are diagrams showing a situation wherein the object displayed on the display unit  5  based on the Web browsing program is subjected to enlarging processing according to the long-pressing operations and displayed. Also,  FIG. 16(   a ) shows the correlation between the time of the long-pressing operation and the enlargement scale of the object. 
         [0185]    As can be seen from  FIG. 16(   a ), in the case of the cellular phone, when the enlargement scale (display scale) of the object subjected to enlarging processing by a long-pressing operation by the operator is 1.0 times, regardless of the long-pressing operation being performed by the operator, the enlarging processing of the object is stopped for 200 msec for example, and at a timing that the 200 msec have elapsed, the enlarging processing of the object corresponding to the long-pressing operation of the operator is performed again. 
         [0186]    As shown in  FIG. 15(   a ) for example, the control unit  15  first displays the object on the display unit  5  at an enlargement scale of 0.8 times, performs enlargement processing of the object according to the long-pressing operation, and when the enlargement scale of the object reaches an enlargement scale of 1.0 times, stops the enlargement processing of the object for a predetermined amount of time such as 200 msec or the like, regardless of the long-pressing operation being performed as shown in  FIG. 15(   b ) and  FIG. 15(   c ). The control unit  15  then resumes the enlarging processing of the object as shown in  FIG. 15(   d ), corresponding to the long-pressing operations of the operator, after the predetermined amount of time having elapsed. 
         [0187]    Thus, even if the long-pressing operation is continuously performed, the enlargement scale of the object is controlled so as to temporarily be stopped at an enlargement scale of 1.0 times, the object can easily be subjected to display operations at an enlargement scale of 1.0 times. In other words, an object having an enlargement scale of 1.0 times, which has a great probability of being the desired scale of the operator, can be easily displayed. 
         [0188]    With the example shown in  FIG. 16(   a ), the enlargement scale of the object is linearly increased according to the long-pressing operation of the operator, and in the event of reaching the enlargement scale of 1.0 times, the enlargement processing is stopped for a predetermined amount of time such as 200 msec as mentioned above, and after the predetermined amount of time has elapsed, the enlargement scale of the object is again linearly increased according to the long-pressing operations by the operator. 
         [0189]    The enlargement scale of the object is increased according to the long-pressing operations of the operator as shown in  FIG. 16(   b ), and when the enlargement scale nears 1.0 times, the width of the enlargement processing is gradually reduced, whereby the enlargement scale reaches 1.0 times following a curve, and in the event of reaching the enlargement scale of 1.0 times, the enlargement processing is stopped for a predetermined amount of time such as 200 msec as shown above. After the predetermined amount of time has elapsed, the enlargement scale of the object may be increased again following a curve according to the long-pressing operation by the operator. 
         [0190]    In this case, when the enlargement scale of the object subjected to long-pressing operations nears an enlargement scale of 1.0 times, the enlargement width of the object becomes smaller and the object reaches an enlargement scale of 1.0 times as mentioned above, and during the predetermined amount of time such as the 200 msec mentioned above, the enlarging processing is stopped. Therefore, as the enlargement scale of the object nears the enlargement scale of 1.0 times, the enlargement width gradually becomes smaller, and the enlargement processing eventually stops. Also, in the event that the enlargement processing is resumed after a predetermined amount of time having elapsed, the enlargement width gradually is increased, and eventually the enlargement processing of the object is performed linearly according to the long-pressing operations. Therefore, an enlarging processing with natural changes can be shown to the user. 
         [0191]    Note that in the examples shown in  FIG. 15(   a ) through  FIG. 15(   d ) and  FIG. 16(   a ) and  FIG. 16(   b ), the enlargement processing is controlled to stop for a predetermined amount of time in the event that the enlargement scale reaches 1.0 times, but the enlargement scale at which to stop the enlargement processing may be optionally set by the operator or the cellular phone maker, to be other than 1.0 times. 
         [0192]    Also, with the example shown in  FIG. 15(   a ) through  FIG. 15(   d ) and  FIG. 16(   a ) and  FIG. 16(   b ), the enlargement processing is controlled to stop for a predetermined amount of time in the event that the enlargement scale reaches 1.0 times, but the enlargement processing may be stopped for a predetermined amount of time when the enlargement scale reaches 1.0 times and when the enlargement scale reaches 2.0 times, respectively. In other words, the enlargement processing may be controlled to be stopped multiple times at desired timings of the enlargement scale, not only limited to once in the event that the enlargement scale reaches 1.0 times. 
         [0193]    Further, the example as described above is an example in the case of enlargement operations of an object, but performing reduction operations of an object will be similar to that described above. 
         [0194]    That is to say, in the case that long-pressing operations to specify reduction processing in the event that an object having a display scale of 2.0 times is displayed, the control unit  15  subjects the object to gradual reduction according to the long-pressing operation, and in the event that the display scale of the object reaches a display scale of 1.0 times, the long-pressing operation performed by the operator is ignored (canceled), and the reduction processing is stopped during the predetermined amount of time. The reduction operation of the object according to long-pressing operation by the operator is resumed at a timing when the predetermined amount of time has elapsed. 
         [0195]    Thus, upon performing long-pressing operations to specify reducing processing, the reduction scale of the still image can be controlled to be temporarily stopped at a reduction scale of 1.0 times, for example, whereby the operator can easily operate to display the object having a reduction scale of 1.0 times. In other words, the object having a display scale of 1.0 times which has a high probability of being desired by the operator can be easily displayed, and also advantages similar to the above descriptions can be obtained. 
       [Switching Processing of Music Player Playing Speed by Dragging Operations] 
       [0196]    Next, the various examples above have described the changing processing of display scale for a predetermined amount of time at a display scale thought to have high usage frequency in the event of change processing of the display scale of the object displayed on the display unit  5 , based on a technical idea of the present disclosure of “during a series of variable controls for variable operations, the variable controls are stopped for a predetermined amount of time at a desired timing”. 
         [0197]    Conversely, the example described below is an example wherein, in the event of performing variable control of the playing speed of a music player, the variable control of the playing speed is stopped for a predetermined amount of time at a predetermined playing speed, based on based on a technical idea of the present disclosure described above. The specific control flow is similar to the control flow shown in the flowchart in  FIG. 2 . 
         [0198]    Upon starting playing of the music data based on the music player program stored in the memory  14 , the control unit  15  monitors the operational situation of the display unit  5 , thereby monitoring whether or not enlarging operations are performed wherein the finger in contact with the display unit  5  is moved in the horizontal direction in a state of remaining in contact. In the case of the cellular phone according to the present embodiment, the dragging operation in the right horizontal direction at time of playing the music data means a variable operation in the direction of increasing the speed of the playing speed. 
         [0199]    Therefore, upon detecting the dragging operation herein the control unit  15  first accelerates the playing speed from 0.1 times to 0.8 times as shown in  FIG. 17(   a ), the playing speed of the music data is changed so as to gradually become a high-speed playing speed according to the dragging operation of the operator, as shown in  FIG. 18(   a ). 
         [0200]    Next, so that the playing speed will thus gradually become a high-speed playing speed, the control unit  15  subjects the playing speed of the music data to change control, whereby the dragging operation that the operator is continuously performing is cancelled with the playing speed reaches a playing speed of 1.0 times, and the change control of the playing speed is stopped for a predetermined amount of time, as shown in  FIG. 17(   b ) and  FIG. 17(   c ). 
         [0201]    Next, upon the predetermined amount of time having elapsed, the control unit  15  subjects the playing speed of the music data to change control so that the playing speed gradually increases again, according to the dragging operation of the operator, as shown in  FIG. 17(   d ) and  FIG. 18(   a ). 
         [0202]    Thus, even if the dragging operation is continuously performed, the playing speed of the music data is temporarily stopped at the playing speed of 1.0 times, whereby the operator can easily operate at the playing speed of 1.0 times. In other words, the playing speed can be easily operated at a playing speed of 1.0 times, which has a great probability of being the desired speed of the operator. 
         [0203]    With the example shown in  FIG. 18(   a ), the playing speed is linearly increased according to the dragging operation of the operator, and in the event of reaching the playing speed of 1.0 times, change control of the playing speed is stopped for a predetermined amount of time such as 200 msec as mentioned above, and after the predetermined amount of time has elapsed, the playing speed is again linearly increased according to the dragging operations by the operator. 
         [0204]    The playing speed is increased according to the dragging operations of the operator as shown in  FIG. 18(   b ), and when the playing speed nears 1.0 times, the width of the changing processing of the playing speed is gradually reduced, whereby the playing speed reaches 1.0 times following a curve, and in the event of reaching the playing speed of 1.0 times, the changing processing of the playing speed is stopped for a predetermined amount of time such as 200 msec as shown above. After the predetermined amount of time has elapsed, the playing speed may be increased again following a curve according to the dragging operation by the operator. 
         [0205]    In this case, when the playing speed of the music data subjected to changing operations nears an enlargement scale of 1.0 times, the change width of the playing speed of the music data becomes smaller and the playing speed reaches a playing speed of 1.0 times as mentioned above, and during the predetermined amount of time such as the 200 msec mentioned above, the changing processing of the playing speed is stopped. Therefore, as the playing speed of the music data nears 1.0 times, the change width gradually becomes smaller, and the changing processing of the playing speed eventually stops. Also, in the event that the changing processing of the playing speed is resumed after a predetermined amount of time having elapsed, the change width gradually is increased, and eventually the changing processing of the playing speed of the music data is performed linearly according to the dragging operations. Therefore, the playing speed of the music data can be subjected to changing processing in a natural manner. 
         [0206]    Note that in the examples shown in  FIG. 17(   a ) through  FIG. 17(   d ) and  FIG. 18(   a ) and  FIG. 18(   b ), the changing processing of the playing speed is controlled to stop for a predetermined amount of time in the event that the playing speed reaches 1.0 times, but the playing speed, including reverse playing speed, at which to stop the changing processing may be optionally set by the operator or the cellular phone maker, to be other than 1.0 times. 
         [0207]    Also, with the example shown in  FIG. 17(   a ) through  FIG. 17(   d ) and  FIG. 18(   a ) and  FIG. 18(   b ), the changing processing of the playing speed is controlled to stop for a predetermined amount of time in the event that the playing speed reaches 1.0 times, but the changing processing of the playing speed may be stopped for a predetermined amount of time when the enlargement scale reaches 1.0 times and when the enlargement scale reaches 2.0 times, respectively. In other words, the playing processing may be controlled to be stopped multiple times at desired timings of reaching playing speeds, not only limited to once in the event that the playing speed reaches 1.0 times. 
         [0208]    Further, the example as described above is an example in the case of increasing the speed of the music data playing speed, but decreasing the speed of the music data playing speed will be similar to that described above. That is to say, in the case of dragging operations in the left horizontal direction at time of playing the music data, this means variable operations in the direction of reducing the playing speed. 
         [0209]    Therefore, in the event of subjecting the playing speed of the music data to change control to be a playing speed of 2.0 times, when a dragging operation in the left horizontal direction is detected, the control unit  15  gradually reduces the playing speed of the music data from the playing speed of 2.0 times, according to the dragging operation, and in the event that the playing speed is a playing speed of 1.0 times, the dragging operation performed by the operator is cancelled for a predetermined amount of time such as 200 msec, for example, and stops the changing processing of the playing speed for the predetermined amount of time. The change processing of the playing speed according to the dragging operation by the operator is resumed at a timing when the predetermined amount of time has elapsed. 
         [0210]    Thus, even if continuous dragging operations are performed, the changing processing of the playing speed can be controlled to be temporarily stopped at a playing speed of 1.0 times, for example. Therefore, the operator can easily adjust the playing speed of the music data to be a playing speed of 1.0 times. In other words, the playing speed of the music data can be adjusted to be a playing speed of 1.0 times which has a high probability of being desired by the operator. 
         [0211]    Next, change control of the music data playing speed with flicking operations will be described. 
         [0212]      FIG. 19(   a ) and  FIG. 19(   b ) are schematic diagrams to describe the change control of the music data playing speed that the control unit  15  performs based on the music player program. Also,  FIG. 20(   a ) shows the correlation between the strength of the flicking operation and the playing speed. 
         [0213]    As an example, in the case of the cellular phone in the present embodiment, in the event of increasing the playing speed of the music data, the operator performs a flicking operation in the right horizontal direction. 
         [0214]    As can be seen from  FIG. 20(   a ), in the case of the cellular phone, in the case that a strong flicking operation is performed in the right horizontal direction, the music data playing speed is subjected to change control according to the strength of the flicking operation, and in the case that a weak flicking operation is performed in the right horizontal direction, the changing processing of the music data playing speed is temporarily stopped at the above-described playing speed of 1.0 times. 
         [0215]    To detect the strength or weakness of the flicking operation, the control unit  15  computes “operational distance of flicking operation/flicking operation time”, whereby “operational speed of flicking operation” is computed. In the case that the operational speed herein is faster than the predetermined operational speed (i.e. operational speed serving as a threshold), this means that a strong flicking operation is performed, and in the case that the operational speed herein is slower than the predetermined operational speed, this means that a weak flicking operation is performed. 
         [0216]    Therefore, in the case that the control unit  15  detects a strong flicking operation which is a high speed flicking operation, as shown in  FIG. 19(   a ) and  FIG. 20(   a ), the change control of the playing speed is not stopped at the playing speed of 1.0 times as with the description above, but the music data playing speed is controlled to be the playing speed corresponding to the strength of the flicking operation. 
         [0217]    Conversely, in the case that the control unit  15  detects a weak flicking operation which is a slow speed flicking operation, as shown in  FIG. 19(   a ) and  FIG. 20(   a ), the change control of the playing speed is stopped at the enlargement scale of 1.0 times as with the description above. In the case that a flicking operation is performed again after this stopping, the music data playing speed is controlled to be the playing speed corresponding to the strength of the flicking operation. 
         [0218]    Thus, when a weak flicking operation is performed, the change control of the music data playing speed is controlled to be temporarily stopped at an enlargement scale of 1.0 times, whereby the operator can easily set the music data playing speed to be the playing speed of 1.0 times. In other words, the music data playing speed can be easily set to be the playing speed of 1.0 times which has a high probability of being desired by the operator. 
         [0219]    Note that in the event that the playing speed is gradually increased according to a weak flicking operation by the operator and the playing speed nears 1.0 times as shown in  FIG. 20(   b ), the playing speed may be caused to reach 1.0 times following a curve by gradually reducing the change width of the playing speed, and in the event of reaching a playing speed of 1.0 times the change control of the playing speed may be stopped. 
         [0220]    Thus, as the music data playing speed nears the playing speed of 1.0 times, the playing speed change width is gradually decreased, and the playing speed change processing eventually is stopped, whereby the playing speed can be changed in a natural manner. 
         [0221]    Also, according to the example herein, in the event that the playing speed reaches 1.0 times, the change of the playing speed is controlled to be stopped, but even if the playing speed to stop the change control is other than 1.0 times including the reverse playing direction, this can be set optionally by the operator or the maker of the cellular phone. 
         [0222]    Further, performing reduction in the music data playing speed will be similar to that described above. That is to say, in the case of the cellular phone herein, a flicking operation in the left horizontal direction at time of playing the music data is an operation to specify reduction of the playing speed. 
         [0223]    Therefore, when a weak flicking operation in the left horizontal direction is detected in the event of changing the playing speed of the music data playing speed to be 2.0 times, the control unit  15  gradually reduces the music data playing speed according to the weak flicking operation in the left horizontal direction, and in the event that the music data playing speed reaches a playing speed of 1.0 times, the change control of the playing speed is temporarily stopped. 
         [0224]    Thus, even in the case of operating the music data playing speed at a slow speed, the music data playing speed can be controlled to be temporarily stopped at a playing speed of 1.0 times, for example. Therefore, even in the case of operating the music data playing speed at a slow speed, the operator can easily adjust the music data playing speed to be a playing speed of 1.0 times. In other words, the music data playing speed can be easily adjusted to be 1.0 times which has a high probability of being desired by the operator. 
         [0225]    Next, change control of the music data playing speed with long-pressing operations will be described. 
         [0226]      FIG. 21(   a ) through  FIG. 21(   d ) are schematic diagrams to describe the change control of the music data playing speed performed by the control unit  15  according to long-pressing operations by the operator, based on the music player program. Also,  FIG. 22(   a ) is a diagram showing the correlation between the time of the long-pressing operation and the playing speed. 
         [0227]    Upon starting playing of the music data based on the music player program stored in the memory  14 , the control unit  15  monitors the operational situation of the display unit  5 , thereby monitoring whether or not long-pressing operations are performed wherein a finger presses the display unit  5  for a predetermined amount of time. In the case of the cellular phone according to the present embodiment, the long-pressing operation with one finger at time of playing the music data means a variable operation in the direction of increasing the speed of the playing speed. Note that although described later, a long-pressing operation with two fingers at the time of music data playing means a variable operation in the direction of decreasing the speed of the playing speed. 
         [0228]    Therefore, upon detecting the long-pressing operation with one finger herein the control unit  15  first accelerates the playing speed from 0.1 times to 0.8 times as shown in  FIG. 21(   a ), the playing speed of the music data is changed so as to gradually become a high-speed playing speed according to the long-pressing operation of the operator, as shown in  FIG. 22(   a ). 
         [0229]    Next, so that the playing speed will thus gradually become a high-speed playing speed, the control unit  15  subjects the playing speed of the music data to change control, whereby the long-pressing operation that the operator is continuously performing is cancelled when the playing speed reaches a playing speed of 1.0 times, and the change control of the playing speed is stopped for a predetermined amount of time, as shown in  FIG. 21(   b ) and  FIG. 21(   c ). 
         [0230]    Next, upon the predetermined amount of time having elapsed, the control unit  15  subjects the playing speed of the music data to change control so that the playing speed gradually increases again, according to the long-pressing operation of the operator, as shown in  FIG. 21(   d ) and  FIG. 22(   a ). 
         [0231]    Thus, even if the long-pressing operation is continuously performed, the playing speed of the music data is temporarily stopped at the playing speed of 1.0 times, whereby the operator can easily operate at the playing speed of 1.0 times. In other words, the playing speed can be easily operated at a playing speed of 1.0 times, which has a great probability of being the desired speed of the operator. 
         [0232]    With the example shown in  FIG. 22(   a ), the playing speed is linearly increased according to the dragging operation of the operator, and in the event of reaching the playing speed of 1.0 times, change control of the playing speed is stopped for a predetermined amount of time such as 200 msec as mentioned above, and after the predetermined amount of time has elapsed, the playing speed is again linearly increased according to the long-pressing operations by the operator. 
         [0233]    The playing speed is increased according to the long-pressing operations of the operator as shown in  FIG. 22(   b ), and when the playing speed nears 1.0 times, the width of the changing processing of the playing speed is gradually reduced, whereby the playing speed reaches 1.0 times following a curve, and in the event of reaching the playing speed of 1.0 times, the changing processing of the playing speed is stopped for a predetermined amount of time such as 200 msec as shown above. After the predetermined amount of time has elapsed, the playing speed may be increased again following a curve according to the dragging operation by the operator. 
         [0234]    In this case, when the playing speed of the music data subjected to changing operations nears an enlargement scale of 1.0 times, the change width of the playing speed of the music data becomes smaller and the playing speed reaches a playing speed of 1.0 times as mentioned above, and during the predetermined amount of time such as the 200 msec mentioned above, the changing processing of the playing speed is stopped. Therefore, as the playing speed of the music data nears 1.0 times, the change width gradually becomes smaller, and the changing processing of the playing speed eventually stops. Also, in the event that the changing processing of the playing speed is resumed after a predetermined amount of time having elapsed, the change width gradually is increased, and eventually the changing processing of the playing speed of the music data is performed linearly according to the dragging operations. Therefore, the playing speed of the music data can be subjected to changing processing in a natural manner. 
         [0235]    Note that in the examples shown in  FIG. 21(   a ) through  FIG. 21(   d ) and  FIG. 22(   a ) and  FIG. 22(   b ), the changing processing of the playing speed is controlled to stop for a predetermined amount of time in the event that the playing speed reaches 1.0 times, but the playing speed at which to stop the changing processing may be optionally set by the operator or the cellular phone maker, to be other than 1.0 times. 
         [0236]    Also, with the example shown in  FIG. 21(   a ) through  FIG. 21(   d ) and  FIG. 22(   a ) and  FIG. 22(   b ), the changing processing of the playing speed is controlled to stop for a predetermined amount of time in the event that the playing speed reaches 1.0 times, but the changing processing of the playing speed may be stopped for a predetermined amount of time when the enlargement scale reaches 1.0 times and when the enlargement scale reaches 2.0 times, respectively. In other words, the playing processing may be controlled to be stopped multiple times at desired timings of reaching playing speeds, not only limited to once in the event that the playing speed reaches 1.0 times. 
         [0237]    Further, the example as described above is an example in the case of increasing the speed of the music data playing speed, but decreasing the speed of the music data playing speed will be similar to that described above. That is to say, in the case of long-pressing operations with two fingers as described above, this means variable operations in the direction of reducing the playing speed. 
         [0238]    Therefore, in the event of subjecting the playing speed of the music data to change control to be a playing speed of 2.0 times, when a long-pressing operations with two fingers as described above is detected, the control unit  15  gradually reduces the playing speed of the music data from the playing speed of 2.0 times, according to the long-pressing operation, and in the event that the playing speed is a playing speed of 1.0 times, the long-pressing operations with two fingers performed by the operator is cancelled for a predetermined amount of time such as 200 msec, for example, and stops the changing processing of the playing speed for the predetermined amount of time. The change processing of the playing speed according to the long-pressing operations with two fingers by the operator is resumed at a timing when the predetermined amount of time has elapsed. 
         [0239]    Thus, even if continuous long-pressing operations with two fingers are performed, the changing processing of the playing speed can be controlled to be temporarily stopped at a playing speed of 1.0 times, for example. Therefore, the operator can easily adjust the playing speed of the music data to be a playing speed of 1.0 times. In other words, the playing speed of the music data can be adjusted to be a playing speed of 1.0 times which has a high probability of being desired by the operator. 
         [0240]    Next, the above-described example is an example of operations to change the playing speed of music data, but change control of the playing speed of moving picture data according to various operations will be described below. 
         [0241]    Upon starting playing of the moving picture data based on the moving picture player program of the camera control program stored in the memory  14 , the control unit  15  monitors the operational situation of the display unit  5 , thereby monitoring whether or not dragging operations are performed wherein the finger in contact with the display unit  5  is moved in the horizontal direction in a state of remaining in contact. In the case of the cellular phone according to the present embodiment, the dragging operation in the right horizontal direction at time of playing the moving picture data means a variable operation in the direction of increasing the speed of the playing speed. 
         [0242]    Therefore, upon detecting the dragging operation herein the control unit  15  first reduces the playing speed to 0.8 times as shown in  FIG. 23(   a ), the playing speed of the moving picture data is changed so as to gradually become a high-speed playing speed according to the dragging operation of the operator, as shown in  FIG. 24(   a ). 
         [0243]    Next, so that the playing speed will thus gradually become a high-speed playing speed, the control unit  15  subjects the playing speed of the moving picture data to change control, whereby the dragging operation that the operator is continuously performing is cancelled when the playing speed reaches a playing speed of 1.0 times, and the change control of the playing speed is stopped for a predetermined amount of time, as shown in  FIG. 23(   b ) and  FIG. 23(   c ). 
         [0244]    Next, upon the predetermined amount of time having elapsed, the control unit  15  subjects the playing speed of the moving picture data to change control so that the playing speed gradually increases again, according to the dragging operation of the operator, as shown in  FIG. 23(   d ) and  FIG. 24(   a ). 
         [0245]    Thus, even if the dragging operation is continuously performed, the playing speed of the moving picture data is temporarily stopped at the playing speed of 1.0 times, whereby the operator can easily operate at the playing speed of 1.0 times. In other words, the playing speed can be easily operated at a playing speed of 1.0 times, which has a great probability of being the desired speed of the operator. 
         [0246]    With the example shown in  FIG. 24(   a ), the playing speed is linearly increased according to the dragging operation of the operator, and in the event of reaching the playing speed of 1.0 times, change control of the playing speed is stopped for a predetermined amount of time such as 200 msec as mentioned above, and after the predetermined amount of time has elapsed, the playing speed is again linearly increased according to the dragging operations by the operator. 
         [0247]    The playing speed is increased according to the dragging operations of the operator as shown in  FIG. 24(   b ), and when the playing speed nears 1.0 times, the width of the changing processing of the playing speed is gradually reduced, whereby the playing speed reaches 1.0 times following a curve, and in the event of reaching the playing speed of 1.0 times, the changing processing of the playing speed is stopped for a predetermined amount of time such as 200 msec as shown above. After the predetermined amount of time has elapsed, the playing speed may be increased again following a curve according to the dragging operation by the operator. 
         [0248]    In this case, when the playing speed of the moving picture data subjected to changing operations nears an enlargement scale of 1.0 times, the change width of the playing speed of the moving picture data becomes smaller and the playing speed reaches a playing speed of 1.0 times as mentioned above, and during the predetermined amount of time such as the 200 msec mentioned above, the changing processing of the playing speed is stopped. Therefore, as the playing speed of the moving picture data nears 1.0 times, the change width gradually becomes smaller, and the changing processing of the playing speed eventually stops. Also, in the event that the changing processing of the playing speed is resumed after a predetermined amount of time having elapsed, the change width gradually is increased, and eventually the changing processing of the playing speed of the moving picture data is performed linearly according to the dragging operations. Therefore, the playing speed of the moving picture data can be subjected to changing processing in a natural manner. 
         [0249]    Note that in the examples shown in  FIG. 23(   a ) through  FIG. 23(   d ) and  FIG. 24(   a ) and  FIG. 24(   b ), the changing processing of the playing speed is controlled to stop for a predetermined amount of time in the event that the playing speed reaches 1.0 times, but the playing speed at which to stop the changing processing may be optionally set by the operator or the cellular phone maker, to be other than 1.0 times. 
         [0250]    Also, with the example shown in  FIG. 23(   a ) through  FIG. 23(   d ) and  FIG. 24(   a ) and  FIG. 24(   b ), the changing processing of the playing speed is controlled to stop for a predetermined amount of time in the event that the playing speed reaches 1.0 times, but the changing processing of the playing speed may be stopped for a predetermined amount of time when the enlargement scale reaches 1.0 times and when the enlargement scale reaches 2.0 times, respectively. In other words, the playing processing may be controlled to be stopped multiple times at desired timings of reaching playing speeds, not only limited to once in the event that the playing speed reaches 1.0 times. 
         [0251]    Further, the example as described above is an example in the case of increasing the speed of the moving picture data playing speed, but decreasing the speed of the moving picture data playing speed will be similar to that described above. That is to say, in the case of dragging operations in the left horizontal direction at time of playing the moving picture data, this means variable operations in the direction of reducing the playing speed. 
         [0252]    Therefore, in the event of subjecting the playing speed of the moving picture data to change control to be a playing speed of 2.0 times, when a dragging operation in the left horizontal direction is detected, the control unit  15  gradually reduces the playing speed of the moving picture data from the playing speed of 2.0 times, according to the dragging operation, and in the event that the playing speed is a playing speed of 1.0 times, the dragging operation performed by the operator is cancelled for a predetermined amount of time such as 200 msec, for example, and stops the changing processing of the playing speed for the predetermined amount of time. The change processing of the playing speed according to the dragging operation by the operator is resumed at a timing when the predetermined amount of time has elapsed. 
         [0253]    Thus, even if continuous dragging operations are performed in the left horizontal direction, the changing processing of the playing speed can be controlled to be temporarily stopped at a playing speed of 1.0 times, for example. Therefore, the operator can easily adjust the playing speed of the moving picture data to be a playing speed of 1.0 times. In other words, the playing speed of the moving picture data can be adjusted to be a playing speed of 1.0 times which has a high probability of being desired by the operator. 
         [0254]    Next, change control of the moving picture data playing speed with flicking operations will be described. 
         [0255]      FIG. 25(   a ) and  FIG. 25(   b ) are schematic diagrams to describe the change control of the moving picture data playing speed that the control unit  15  performs based on the music player program. Also,  FIG. 26(   a ) shows the correlation between the strength of the flicking operation and the playing speed. 
         [0256]    As an example, in the case of the cellular phone in the present embodiment, in the event of increasing the playing speed of the moving picture data, the operator performs a flicking operation in the right horizontal direction. 
         [0257]    As can be seen from  FIG. 26(   a ), in the case of the cellular phone, in the case that a strong flicking operation is performed in the right horizontal direction, the moving picture data playing speed is subjected to change control according to the strength of the flicking operation, and in the case that a weak flicking operation is performed in the right horizontal direction, the changing processing of the moving picture data playing speed is temporarily stopped at the above-described playing speed of 1.0 times. 
         [0258]    To detect the strength or weakness of the flicking operation, the control unit  15  computes “operational distance of flicking operation/flicking operation time”, whereby “operational speed of flicking operation” is computed. In the case that the operational speed herein is faster than the predetermined operational speed (i.e. operational speed serving as a threshold), this means that a strong flicking operation is performed, and in the case that the operational speed herein is slower than the predetermined operational speed, this means that a weak flicking operation is performed. 
         [0259]    Therefore, in the case that the control unit  15  detects a strong flicking operation which is a high speed flicking operation, as shown in  FIG. 25(   a ) and  FIG. 26(   a ), the change control of the playing speed is not stopped at the playing speed of 1.0 times as with the description above, but the moving picture data playing speed is controlled to be the playing speed corresponding to the strength of the flicking operation. 
         [0260]    Conversely, in the case that the control unit  15  detects a weak flicking operation which is a slow speed flicking operation, as shown in  FIG. 25(   b ) and  FIG. 26(   a ), the change control of the moving picture playing speed is stopped at the playing speed of 1.0 times as with the description above. In the case that a flicking operation is performed again after this stopping, the moving picture data playing speed is controlled to be the playing speed corresponding to the strength of the flicking operation. 
         [0261]    Thus, when a weak flicking operation is performed, the change control of the moving picture data playing speed is controlled to be temporarily stopped at an enlargement scale of 1.0 times, whereby the operator can easily set the moving picture data playing speed to be the playing speed of 1.0 times. In other words, the moving picture data playing speed can be easily set to be the playing speed of 1.0 times which has a high probability of being desired by the operator. 
         [0262]    Note that in the event that the playing speed is gradually increased according to a weak flicking operation by the operator and the playing speed nears 1.0 times as shown in  FIG. 26(   b ), the playing speed may be caused to reach 1.0 times following a curve by gradually reducing the change width of the playing speed, and in the event of reaching a playing speed of 1.0 times the change control of the playing speed may be stopped. 
         [0263]    Thus, as the moving picture data playing speed nears the playing speed of 1.0 times, the playing speed change width is gradually decreased, and the playing speed change processing eventually is stopped, whereby the playing speed of the moving picture data can be changed in a natural manner. 
         [0264]    Also, according to the example herein, in the event that the playing speed reaches 1.0 times, the change of the playing speed is controlled to be stopped, but even if the playing speed to stop the change control is other than 1.0 times, this can be set optionally by the operator or the maker of the cellular phone. 
         [0265]    Further, performing reduction in the moving picture data playing speed will be similar to that described above. That is to say, in the case of the cellular phone herein, a flicking operation in the left horizontal direction at time of playing the moving picture data is an operation to specify reduction of the playing speed. 
         [0266]    Therefore, when a weak flicking operation in the left horizontal direction is detected in the event of changing the playing speed of the moving picture data playing speed to be 2.0 times, the control unit  15  gradually reduces the moving picture data playing speed according to the weak flicking operation in the left horizontal direction, and in the event that the moving picture data playing speed reaches a playing speed of 1.0 times, the change control of the playing speed is temporarily stopped. 
         [0267]    Thus, even in the case of operating the moving picture data playing speed at a slow speed, the moving picture data playing speed can be controlled to be temporarily stopped at a playing speed of 1.0 times, for example. Therefore, even in the case of operating the moving picture data playing speed at a slow speed, the operator can easily adjust the moving picture data playing speed to be a playing speed of 1.0 times. In other words, the moving picture data playing speed can be easily adjusted to be 1.0 times which has a high probability of being desired by the operator. 
         [0268]    Next, change control of the moving picture data playing speed with long-pressing operations will be described. 
         [0269]      FIG. 27(   a ) through  FIG. 27(   d ) are schematic diagrams to describe the change control of the moving picture data playing speed performed by the control unit  15  according to long-pressing operations by the operator, based on the moving picture player program. Also,  FIG. 28(   a ) is a diagram showing the correlation between the time of the long-pressing operation and the playing speed. 
         [0270]    Upon starting playing of the moving picture data based on the moving picture player program stored in the memory  14 , the control unit  15  monitors the operational situation of the display unit  5 , thereby monitoring whether or not long-pressing operations are performed wherein a finger presses the display unit  5  for a predetermined amount of time. In the case of the cellular phone according to the present embodiment, the long-pressing operation with one finger at time of playing the moving picture data means a variable operation in the direction of increasing the speed of the playing speed. Note that although described later, a long-pressing operation with two fingers at the time of moving picture data playing means a variable operation in the direction of decreasing the speed of the playing speed. 
         [0271]    Therefore, upon detecting the long-pressing operation with one finger herein the control unit  15  first reduces the playing speed to 0.8 times as shown in  FIG. 27(   a ), the playing speed of the moving picture data is changed so as to gradually become a high-speed playing speed according to the long-pressing operation of the operator, as shown in  FIG. 28(   a ). 
         [0272]    Next, so that the playing speed will thus gradually become a high-speed playing speed, the control unit  15  subjects the playing speed of the moving picture data to change control, whereby the long-pressing operation that the operator is continuously performing is cancelled when the playing speed reaches a playing speed of 1.0 times, and the change control of the playing speed is stopped for a predetermined amount of time, as shown in  FIG. 27(   b ) and  FIG. 27(   c ). 
         [0273]    Next, upon the predetermined amount of time having elapsed, the control unit  15  subjects the playing speed of the moving picture data to change control so that the playing speed gradually increases again, according to the long-pressing operation of the operator, as shown in  FIG. 27(   d ) and  FIG. 28(   a ). 
         [0274]    Thus, even if the long-pressing operation is continuously performed, the playing speed of the moving picture data is temporarily stopped at the playing speed of 1.0 times, whereby the operator can easily operate at the playing speed of 1.0 times. In other words, the playing speed can be easily operated at a playing speed of 1.0 times, which has a great probability of being the desired speed of the operator. 
         [0275]    With the example shown in  FIG. 28(   a ), the playing speed is linearly increased according to the long-pressing operation of the operator, and in the event of reaching the playing speed of 1.0 times, change control of the playing speed is stopped for a predetermined amount of time such as 200 msec as mentioned above, and after the predetermined amount of time has elapsed, the playing speed is again linearly increased according to the long-pressing operations by the operator. 
         [0276]    The playing speed is increased according to the long-pressing operations of the operator as shown in  FIG. 28(   b ), and when the playing speed nears 1.0 times, the width of the changing processing of the playing speed is gradually reduced, whereby the playing speed reaches 1.0 times following a curve, and in the event of reaching the playing speed of 1.0 times, the changing processing of the playing speed is stopped for a predetermined amount of time such as 200 msec as shown above. After the predetermined amount of time has elapsed, the playing speed may be increased again following a curve according to the long-pressing operation by the operator. 
         [0277]    In this case, when the playing speed of the moving picture data subjected to changing operations nears an enlargement scale of 1.0 times, the change width of the playing speed of the moving picture data becomes smaller and the playing speed reaches a playing speed of 1.0 times as mentioned above, and during the predetermined amount of time such as the 200 msec mentioned above, the changing processing of the playing speed is stopped. Therefore, as the playing speed of the moving picture data nears 1.0 times, the change width gradually becomes smaller, and the changing processing of the playing speed eventually stops. Also, in the event that the changing processing of the playing speed is resumed after a predetermined amount of time having elapsed, the change width gradually is increased, and eventually the changing processing of the playing speed of the moving picture data is performed linearly according to the dragging operations. Therefore, the playing speed of the moving picture data can be subjected to changing processing in a natural manner. 
         [0278]    Note that in the examples shown in  FIG. 27(   a ) through  FIG. 27(   d ) and  FIG. 28(   a ) and  FIG. 28(   b ), the changing processing of the playing speed is controlled to stop for a predetermined amount of time in the event that the playing speed reaches 1.0 times, but the playing speed at which to stop the changing processing may be optionally set by the operator or the cellular phone maker, to be other than 1.0 times. 
         [0279]    Also, with the example shown in  FIG. 27(   a ) through  FIG. 27(   d ) and  FIG. 28(   a ) and  FIG. 28(   b ), the changing processing of the playing speed is controlled to stop for a predetermined amount of time in the event that the playing speed reaches 1.0 times, but the changing processing of the playing speed may be stopped for a predetermined amount of time when the enlargement scale reaches 1.0 times and when the enlargement scale reaches 2.0 times, respectively. In other words, the playing processing may be controlled to be stopped multiple times at desired timings of reaching playing speeds, not only limited to once in the event that the playing speed reaches 1.0 times. 
         [0280]    Further, the example as described above is an example in the case of increasing the speed of the moving picture data playing speed, but decreasing the speed of the moving picture data playing speed will be similar to that described above. That is to say, in the case of long-pressing operations with two fingers as described above, this means variable operations in the direction of reducing the playing speed. 
         [0281]    Therefore, in the event of subjecting the playing speed of the moving picture data to change control to be a playing speed of 2.0 times, when a long-pressing operations with two fingers as described above is detected, the control unit  15  gradually reduces the playing speed of the moving picture data from the playing speed of 2.0 times, according to the long-pressing operation, and in the event that the playing speed is a playing speed of 1.0 times, the long-pressing operations with two fingers performed by the operator is cancelled for a predetermined amount of time such as 200 msec, for example, and stops the changing processing of the playing speed for the predetermined amount of time. The change processing of the playing speed according to the long-pressing operations with two fingers by the operator is resumed at a timing when the predetermined amount of time has elapsed. 
         [0282]    Thus, even if continuous long-pressing operations with two fingers are performed, the changing processing of the playing speed can be controlled to be temporarily stopped at a playing speed of 1.0 times, for example. Therefore, the operator can easily adjust the playing speed of the moving picture data to be a playing speed of 1.0 times. In other words, the playing speed of the moving picture data can be adjusted to be a playing speed of 1.0 times which has a high probability of being desired by the operator. 
         [0283]    Next, the various examples above have described the changing processing of display scale for a predetermined amount of time at a display scale thought to have high usage frequency in the event of change processing of the display scale of the object displayed on the display unit  5 , based on a technical idea according to the present disclosure of “during a series of variable controls for variable operations, the variable controls are stopped for a predetermined amount of time at a desired timing”. 
         [0284]    Conversely, the example described below is an example wherein, in the event of performing variable control of the playing speed of music data or moving picture data, the changing processing of the playing speed is stopped for a predetermined amount of time at a playing speed that is thought to have a high usage frequency, based on based on a technical idea according to the present disclosure described above. 
         [0285]    Conversely, the example described below is an example based on a technical idea according to the present disclosure described above wherein, in the event of switching multiple still images continuously and displaying on the display unit  5 , the switching display processing is stopped for a predetermined amount of time at a change of day or change of month, for example, based on time information such as imaging point-in-time or obtaining point-in-time provided to each still image. 
         [0286]    The flowchart in  FIG. 29  shows the still image switching processing flow. Upon display specifying operations of the still image having been performed by the operator, the still image specified by the operator is displayed on the display unit  5 , based on the viewer program of the camera control program stored in the memory  14 . The control unit  15  monitors whether or not there has been any switching operations of the still image at a timing wherein the still image is controlled to display on the display unit  5 , and upon detecting switching operations, the processing shown in the flowchart in  FIG. 29  is started, based on the viewer program of the camera control program. 
         [0287]    Note that with this example, upon detecting one of the “dragging operations”, “flicking operations”, and “long-pressing operations”, the control unit  15  performs switching operations of the still images. 
         [0288]    Upon such switching operations having been performed by the operator, in step S 51  the control unit  15  sequentially reads out the still images stored in the memory  14 , and sequentially displays the still images read in above with a display mode wherein an image enters the frame from the right edge portion of the display unit  5  and exits towards the left edge portion of the display unit  5 , and advances the processing to step S 52 . 
         [0289]    In step S 52 , the control unit  15  determines whether or not switching operations are being continuously performed by the operator. In the case determination is made that switching operations are not continuing, the control unit  15  advances the processing to step S 53 , stops the switching processing of the still images as described above, and ends the processing shown in the flow chart shown in  FIG. 29 . 
         [0290]    Conversely, in the case determination is made in step S 52  that switching operations are being continuously made, the control unit  15  advances the processing to step S 53 , and determines whether or not the date shown on the date information provided to the still image is the predetermined date. 
         [0291]    Specifically, upon a subject being shot with a camera unit  8 , the control unit  15  obtains the point-in-time information showing the current date and time from a timer  10 , and provides the point-in-time information showing the current date and time to the shot still image as imaging point-in-time information in the memory  14 . 
         [0292]    Also, in the case of storing the still images obtained externally in the memory  14 , as with the still images obtained via a network or the like, the control unit  15  obtains the point-in-time information showing the current date and time from the timer  10 , and provides the point-in-time information showing the current date and time to the obtained still image as obtained point-in-time information in the memory  14 . 
         [0293]    Upon starting the switching processing in step S 51 , the control unit  15  determines whether or not the still image to which the point-in-time information of the predetermined date has been displayed on the display unit  5 , based on the point-in-time information such as the imaging point-in-time information or obtained point-in-time information provided on the various still images. Until determination is made that the still image to which the point-in-time information of the predetermined date is provided has been displayed on the display unit  5 , the control unit  15  returns the processing to step S 51 , and continues to execute the switching processing of the still images. 
         [0294]    Conversely, upon determining that the still image to which the point-in-time information of the predetermined date is provided has been displayed on the display unit  5 , the control unit  15  advances the processing to step S 54 , stops the switching processing of the still images and advances the processing to step S 55 . In step S 55 , the control unit  15  determines whether or not a predetermined amount of time such as 200 msec, for example, has elapsed from the time that the still image switching processing has been stopped, based on the time information obtained from the timer  10 , and in the event of determining that the predetermined amount of time has elapsed, advances the processing to step S 56 . 
         [0295]    In step S 56 , the control unit  15  monitors the operational situation of the display unit  5 , thereby determining whether or not switching operations are being continuously performed by the operator. In the case determination is made that switching operations are not being continuously performed by the operator, the control unit  15  advances the processing to step S 57 , stops the still image switching processing, and ends the processing shown in the flowchart in  FIG. 29 . 
         [0296]    Conversely, in the case determination is made in step S 56  that switching operations are being continuously performed by the operator, the control unit  15  advances the processing to step S 58 , resumes the still image switching processing, and returns the processing to step S 53 . In step S 53 , determination is made as to whether or not the still image to which the point-in-time information with the predetermined date has been provided has been displayed on the display unit  5 , and in the event determination is made that the still image to which the point-in-time information with the predetermined date has been provided has been displayed on the display unit  5 , operations to stop the still image switching processing is repeatedly executed. The still image switching processing of the cellular phone will be described using specific examples. 
         [0297]      FIG. 30(   a ) through  FIG. 30(   f ) are diagrams showing a situation wherein the still image displayed on the display unit  5  is subjected to switching processing according to the dragging operations by the operator.  FIG. 31(   a ) is a diagram showing the correlation between the dragging operation distance and the number of still images to be switched. 
         [0298]    As an example, as can be seen from  FIG. 31(   a ), in the case of the cellular phone herein, by performing still image switching, the switching processing is stopped for a predetermined amount of time in the event that the year shown in the point-in-time information provided to the still image is changed. 
         [0299]    By performing the still image switching processing, if the control unit  15  performs the still image switching processing in the order of Oct. 6, 2009→Nov. 23, 2009→Dec. 31, 2009→Jan. 1, 2010 as shown in  FIG. 30(   a ) through  FIG. 30(   c ), the still image switching processing is stopped for a predetermined amount of time at the timing that the still image to which the point-in-time information of Jan. 1, 2010 is provided, which is the still image to which the earliest point-in-time information of 2010 in this case is provided, is displayed. 
         [0300]    Similarly, by performing the still image switching processing, if the control unit  15  performs the still image switching processing in the order of Nov. 6, 2009→Dec. 10, 2009→Dec. 31, 2009→Jan. 1, 2010 as shown in  FIG. 30(   a ) through  FIG. 30(   c ), the still image switching processing is stopped for a predetermined amount of time at the timing that the still image to which the point-in-time information of Jan. 1, 2010 is provided, which is the still image to which the earliest point-in-time information of 2010 in this case is provided, is displayed. 
         [0301]    Thus, immediately following the year shown in the point-of-time provided to the still images having been changed, the still image switching processing is stopped for a predetermined amount of time. That is to say, in the event of searching for a desired still image by performing the still image switching operations, regardless of continuous switching processing being performed, switching processing is temporarily stopped at the year change, whereby the operator can perform a search of the desired still images while visually confirming the year change. Therefore, a desired still image can be quickly searched from a large number of still imaging. Also, the stopping as mentioned above may be at Dec. 31, 2009, immediately before the year changes. 
         [0302]    The example shown in  FIG. 31(   a ) is an example wherein, in the event that the point-in-time information provided to the still image to be switched out by the dragging operation by the operator displays the predetermined date such as the change in year as described above, the switching processing is stopped for a predetermined amount of time such as 200 msec, and after the predetermined amount of time has elapsed, the switching processing is resumed according to the dragging operations by the operator. 
         [0303]    An arrangement may be made wherein the still images are subject to switching processing according to the dragging operation by the operator as shown in  FIG. 31(   b ), and in the event that the date provided to the still image nears the predetermined date, the switching speed is gradually slowed down, and the switching processing is stopped for a predetermined amount of time at a iteming displaying the still image with the predetermined date. Upon the predetermined amount of time having elapsed, the switching processing may be resumed so as to gradually increase the switching speed. Thus, switching processing with changes in a natural manner can be performed. 
         [0304]    Note that with the examples shown in  FIG. 30(   a ) through  FIG. 30(   f ) and  FIG. 31(   a ) and  FIG. 31(   b ), the still image switching processing is controlled to be stopped for a predetermined amount of time immediately before the year changes, but the stopping control of the predetermined time can be performed each time the date changes, each time the month changes, each time a folder wherein the still images are stored changes, or each time a certain number of still images changes. 
         [0305]      FIG. 32(   a ) and  FIG. 32(   b ) are diagrams showing a situation wherein the still image displayed on the display unit  5  is subjected to switching processing according to the flicking operations by the operator.  FIG. 33(   a ) is a diagram showing the correlation between the flicking operation strength and the number of still images to be switched. 
         [0306]    As can be seen from  FIG. 33(   a ), in the case that a strong flick is performed, the control unit  15  controls the switching of the number of still images according to the strength of the flicking operation, and in the case that a weak flick is performed, the switching processing of the still images is stopped temporarily at the change in years as described above. 
         [0307]    To detect the strength or weakness of the flicking operation, the control unit  15  computes “operational distance of flicking operation/flicking operation time”, whereby “operational speed of flicking operation” is computed. In the case that the operational speed herein is faster than the predetermined operational speed (i.e. operational speed serving as a threshold), this means that a strong flicking operation is performed, and in the case that the operational speed herein is slower than the predetermined operational speed, this means that a weak flicking operation is performed. 
         [0308]    Therefore, in the case that the control unit  15  detects a strong flicking operation which is a high speed flicking operation, as shown in  FIG. 32(   a ) and  FIG. 33(   a ), switching control of the still images in the number of still images corresponding to the strength of the flicking operation is performed, without stopping the switching control at a change in year. 
         [0309]    Conversely, in the case that the control unit  15  detects a weak flicking operation which is a slow speed flicking operation, as shown in  FIG. 32(   b ) and  FIG. 33(   a ), the switching control of the still images in the number of still images corresponding to the flicking operation is performed, and in the event that a still image having point-in-time information serving as a change in year is displayed, the switching control of the still images is subjected to stopping control immediately beforehand, for a predetermined amount of time. 
         [0310]    Thus, when a weak flicking operation is performed, the switching control of the still image is temporarily subjected to stopping control at a change in year, whereby the operator can perform a search of a desired still image while recognizing the change in year. Therefore, an operator can quickly search for a desired still image from a large number of still images. 
         [0311]    Note that in the event that the still images are subjected to switching processing according to the flicking operations of the operator as shown in  FIG. 33(   b ), and the date provided to the still images nears the predetermined date, the switching speed is gradually decreased and the switching processing is stopped for a predetermined amount of time at a timing at which the still image having the predetermined date is displayed. Thus, switching processing can be performed with natural changes. 
         [0312]    Note that in the examples shown in  FIG. 32(   a ),  FIG. 32(   b ),  FIG. 33(   a ), and  FIG. 33(   b ), the still image switching processing is subjected to stopping control for a predetermined amount of time immediately before the year changes, but this may be controlled so as to stop for a predetermined amount of time as described above, each time the date changes, each time the month changes, each time a folder wherein the still images are stored changes, or each time a certain number of still images change. 
         [0313]      FIG. 34(   a ) through  FIG. 34(   f ) are diagrams showing a situation wherein the still image displayed on the display unit  5  is subjected to switching processing according to the long-pressing operations by the operator.  FIG. 35(   a ) is a diagram showing the correlation between the long-pressing operation distance and the number of still images to be switched. 
         [0314]    As an example, as can be seen from  FIG. 34(   a ), in the case of the cellular phone herein, by performing still image switching, the switching processing is stopped for a predetermined amount of time in the event that the year shown in the point-in-time information provided to the still image is changed. 
         [0315]    That is to say, by performing the still image switching processing, if the control unit  15  performs the still image switching processing in the order of Oct. 6, 2009→Nov. 23, 2009→Dec. 31, 2009→Jan. 1, 2010 as shown in  FIG. 34(   a ) through  FIG. 34(   c ), the still image switching processing is stopped for a predetermined amount of time at the timing that the still image to which the point-in-time information of Jan. 1, 2010 is provided, which is the still image to which the earliest point-in-time information of 2010 in this case is provided, is displayed. 
         [0316]    Similarly, by performing the still image switching processing, if the control unit  15  performs the still image switching processing in the order of Nov. 6, 2009→Dec. 10, 2009→Dec. 31, 2009→Jan. 1, 2010, the still image switching processing is stopped for a predetermined amount of time at the timing that the still image to which the point-in-time information of Jan. 1, 2010 is provided, which is the still image to which the earliest point-in-time information of 2010 in this case is provided, is displayed. Also, stopping may be at Dec. 31, 2009, immediately before the year changes. 
         [0317]    Thus, immediately following the year shown in the point-of-time provided to the still images having been changed, the still image switching processing is stopped for a predetermined amount of time. That is to say, in the event of searching for a desired still image by performing the still image switching operations, regardless of continuous switching processing being performed, switching processing is temporarily stopped at the year change, whereby the operator can perform a search of the desired still images while visually confirming the year change. Therefore, a desired still image can be quickly searched from a large number of still imaging. 
         [0318]    The example shown in  FIG. 35(   a ) is an example wherein, in the event that the point-in-time information provided to the still image to be switched out by the dragging operation by the operator displays the predetermined date such as the change in year as described above, the switching processing is stopped for a predetermined amount of time such as 200 msec, and after the predetermined amount of time has elapsed, the switching processing is resumed according to the long-pressing operations by the operator. 
         [0319]    An arrangement may be made wherein the still images are subject to switching processing according to the long-pressing operation by the operator as shown in  FIG. 35(   b ), and in the event that the date provided to the still image nears the predetermined date, the switching speed is gradually slowed down, and the switching processing is stopped for a predetermined amount of time at a timing displaying the still image with the predetermined date. Upon the predetermined amount of time having elapsed, the switching processing may be resumed so as to gradually increase the switching speed. Thus, switching processing with changes in a natural manner can be performed. 
         [0320]    Note that with the examples shown in  FIG. 34(   a ) through  FIG. 34(   f ) and  FIG. 35(   a ) and  FIG. 35(   b ), the still image switching processing is controlled to be stopped for a predetermined amount of time immediately before the year changes, but the stopping control of the predetermined time can be performed each time the date changes, each time the month changes, each time a folder wherein the still images are stored changes, or each time a certain number of still images changes. 
         [0321]    Next, the timing to stop the above-described switching processing temporarily may be specified by the operator as a desired timing such as every year, every month, and so forth, or point-in-time information provided to each still image may be detected beforehand, and the timing to temporarily stop the switching processing may be automatically set based on the detection results thereof. 
         [0322]    In this case, the operator selects menu items to automatically detect and set the timing to temporarily stop the switching menu, from an operational menu on the cellular phone. Upon this menu item selection operation having been performed, the control unit  15  executes the processing shown in the flowchart in  FIG. 36 , thereby automatically detecting and setting the timing for switching processing of the still images. 
         [0323]    That is to say, upon the menu item having been selected, in step S 61  the control unit  15  detects the still image to which the point-in-time information for the oldest date is provided, and begins the switching processing of the still images in the order from the oldest date to the newest date. 
         [0324]    Upon starting such still image switching processing, first in step S 62  the control unit  15  sets “day” as a candidate for temporarily stopping the switching processing, and advances the processing to step S 63 . 
         [0325]    In step S 63 , the control unit  15  determines whether or not the date of the currently displayed still image and the date of the still image to be displayed next have the same date, and in the case of having the same date, advances the processing to step S 64 , displays the still image having the same date thereof on the display unit  5 , and returns the processing to step S 62 . 
         [0326]    Thus, as long as the date shown with the point-in-time information provided to each still image is the same date for each, the still images having the same date respectively are sequentially switched and displayed on the display unit  5 . 
         [0327]    Next, in step S 63 , in the case determination is made that the date of the currently displayed still image and the date of the still image to be displayed next have different dates, the control unit advances the processing to step S 65 . In step S 65  the control unit  15  determines whether or not the still image having a different date is a still image that is less than the hundredth still image as counted from the still images to which the point-in-time information has the oldest data provided thereto. 
         [0328]    If the still image having a different date is a still image that is the hundredth or greater still image as counted from the still images to which the point-in-time information has the oldest data provided thereto, this means that there are 100 or more still images having the same date. Therefore, in the case determination is made in step S 65  that the still image having a different date is a still images that is the hundredth still image or greater, as counted from the still images to which the point-in-time information has the oldest data provided thereto, the control unit  15  advances the processing to step S 66 . 
         [0329]    In step S 66  the control unit  15  then performs setting for the stopping timing, so as to temporarily stop the still image switching processing for each date, and ends the processing in the flowchart in  FIG. 36 . Note that the setting information showing the stopping timing here is stored in the memory  14 . In the event of performing still image switching control, the control unit  15  reads in the setting information showing the stopping timing that is stored in the memory  14 , and temporarily stops the still image switching control as described above for a predetermined amount of time, at a timing shown in the setting information. 
         [0330]    Next, in step S 65 , the still image having a different date is determined to be a still image that is less than the hundredth still image as counted from the still images to which the point-in-time information of the oldest date is provided, whereby the processing is advanced to step S 67 , and the control unit  15  sets “week” as a candidate for temporarily stopping the switching processing and advances the processing to step S 68 . 
         [0331]    In step S 68 , the control unit  15  distinguishes whether or not the week to which the date of the currently displayed still image belongs and the week to which the date of the still image to be displayed next belongs are the same week, and in the case of being the same week, the control unit  15  advances the processing to step S 69 , displays the still images in the same week thereof on the display unit  5 , and returns the processing to step S 67 . 
         [0332]    Thus, while the weeks to which the dates shown by point-in-time information provided to the various still images belong are each the same week, the still images having the same week herein are sequentially switched and displayed on the display unit  5 . 
         [0333]    Next, in the case determination is made in step S 68  that the week to which the date of the currently displayed still image belongs and the week to which the date of the still image to be displayed next belongs are different weeks, the control unit  15  advances the processing to step S 70 . In step S 70 , the control unit  15  distinguishes whether or not the still image having a different week is a still image that is less than the hundredth still image as counted from the still images to which the point-in-time information has the oldest data provided thereto. 
         [0334]    If the still image having a different week is a still image that is the hundredth still image or greater as counted from the still images to which the point-in-time information has the oldest data provided thereto, this means that there are 100 or more still images having the same week. Therefore, in the case determination is made in step S 70  that the still image having a different week is a still image that is the hundredth still image or greater, as counted from the still images to which the point-in-time information has the oldest data provided thereto, the control unit advances the processing to step S 71 . 
         [0335]    In step S 71  the control unit  15  then performs setting for the stopping timing, so as to temporarily stop the still image switching processing for each week, and ends the processing in the flowchart in  FIG. 36 . In this case, the control unit  15  performs control to temporarily stop the still image switching control for a predetermined amount of time, for each week. 
         [0336]    Next, in step S 70 , the still image having a different week is determined to be a still image that is less than the hundredth still image as counted from the still images to which the point-in-time information of the oldest date is provided, whereby the processing is advanced to step S 72 , and the control unit  15  sets “month” as a candidate for temporarily stopping the switching processing and advances the processing to step S 73 . 
         [0337]    In step S 73 , the control unit  15  distinguishes whether or not the month to which the date of the currently displayed still image belongs and the month to which the date of the still image to be displayed next belongs are the same month, and in the case of being the same month, the control unit  15  advances the processing to step S 74 , displays the still images in the same month thereof on the display unit  5 , and returns the processing to step S 72 . 
         [0338]    Thus, while the months to which the dates shown by point-in-time information provided to the various still images belong are each the same month, the still images having the same month herein are sequentially switched and displayed on the display unit  5 . 
         [0339]    Next, in the case determination is made in step S 73  that the month to which the date of the currently displayed still image belongs and the month to which the date of the still image to be displayed next belongs are different months, the control unit  15  advances the processing to step S 75 . In step S 75 , the control unit  15  distinguishes whether or not the still image having a different month is a still image that is less than the hundredth still image as counted from the still images to which the point-in-time information has the oldest data provided thereto. 
         [0340]    If the still image having a different month is a still image that is the hundredth still image or greater as counted from the still images to which the point-in-time information has the oldest data provided thereto, this means that there are 100 or more still images having the same month. Therefore, in the case determination is made in step S 75  that the still image having a different month is a still image that is the hundredth still image or greater, as counted from the still images to which the point-in-time information has the oldest data provided thereto, the control unit advances the processing to step S 76 . 
         [0341]    In step S 76  the control unit  15  then performs setting for the stopping timing, so as to temporarily stop the still image switching processing for each month, and ends the processing in the flowchart in  FIG. 36 . In this case, the control unit  15  performs control to temporarily stop the still image switching control for a predetermined amount of time, for each month. 
         [0342]    Next, in step S 75 , the still image having a different month is determined to be a still image that is less than the hundredth still image as counted from the still images to which the point-in-time information of the oldest date is provided, whereby the processing is advanced to step S 77 , and the control unit  15  sets “year” as a candidate for temporarily stopping the switching processing and advances the processing to step S 78 . 
         [0343]    In step S 78 , the control unit  15  distinguishes whether or not the year to which the date of the currently displayed still image belongs and the year to which the date of the still image to be displayed next belongs are the same year, and in the case of being the same year, the control unit  15  advances the processing to step S 79 , displays the still images in the same year thereof on the display unit  5 , and returns the processing to step S 77 . 
         [0344]    Thus, while the years to which the dates shown by point-in-time information provided to the various still images belong are each the same year, the still images having the same year herein are sequentially switched and displayed on the display unit  5 . 
         [0345]    Next, in the case determination is made in step S 78  that the year to which the date of the currently displayed still image belongs and the year to which the date of the still image to be displayed next belongs are different years, the control unit  15  advances the processing to step S 80 . In step S 80 , the control unit  15  performs settings for the stopping timing to temporarily stop the still image switching processing for a predetermined amount of time, for each year. 
         [0346]    Thus, with the cellular phone according to the present embodiment, point-in-time information provided to the still images is detected beforehand, the timing at which a predetermined number of images or more exist is automatically set as the timing to temporarily stop the switching processing, and the still image switching processing is performed. Specifically, in the case that there are a predetermined number or greater, such as 100 or more for example, still images having the same date, for example, the control unit  15  performs temporary stopping control of the switching processing for each date. Alternatively, in the case that a predetermined number or more such as 100 or more, for example, still images exist to which the time information of the same month is provided, the control unit  15  performs temporary stopping control of the switching processing for each month. 
         [0347]    Thus, if there are a predetermined number or greater of still images having the point-in-time information for the same day out of the still images stored in the memory  14 , the switching processing is controlled to stop with every change in “day”, if there are equal to or more than a processing number of still images having the point-in-time information for the same week out of the still images stored in the memory  14 , the switching processing is controlled to stop with every change in “week”, if there are equal to or more than a processing number of still images having the point-in-time information for the same month out of the still images stored in the memory  14 , the switching processing is controlled to stop with every change in “month”, and in other cases the switching processing is controlled to stop with every change in “year”. 
         [0348]    Accordingly, switching processing can be controlled to temporarily stop at an optimal timing according to the number of still images stored in the memory  14 , whereby searching for a desired still image is easier. 
         [0349]    Next, an example will be described wherein, in the event of subjecting a phone book to scrolling control, the scrolling control is stopped for a predetermined amount of time at a change in a group to which a user registered in the phone book belongs. 
         [0350]    The flowchart in  FIG. 37  shows the flow of the phone book scrolling control. Upon display specifying operations having been performed for the phone book by an operator, the control unit  15  displays the phone book data registered in the phone book on the display unit  5 , based on the phone book managing program stored in the memory  14 . The control unit  15  monitors whether or not there has been any scrolling operations of the phone book data at a timing of displaying the phone book data on the display unit  5 , and upon detecting scrolling operations, the control unit  15  starts the processing shown in the flowchart in  FIG. 37 , based on the phone book managing program. 
         [0351]    Note that in this example, of the above-described “dragging operations”, “flicking operations”, and “long-pressing operations”, upon one of these being detected, the control unit  15  performs scrolling processing of the phone book data. 
         [0352]    Upon the operator performing such scrolling operations, the control unit  15  starts the scrolling processing of the phone book data in step S 81 , and advances the processing to step S 82 . 
         [0353]    In step S 82 , the control unit  15  determines whether or not the scrolling operations are continuously performed by the operator. In the case determination is made that scrolling operations are not continuing, the control unit  15  advances the processing to step S 87 , stops the above-described phone book data scrolling processing, and ends the processing shown in the flowchart in  FIG. 37  without further processing. 
         [0354]    Conversely, in the case determination is made in step S 82  that scrolling operations are continuing, the control unit  15  advances the processing to step S 83  and scrolls the phone book data, thereby determining whether or not the phone book data corresponding to the user belonging to a predetermined group has been displayed. 
         [0355]    Specifically, a user whose name is Andy and a user whose name is Annie both belong to a group that has the first letter of their names as “A”, and the user information is registered as such in the phone book. Similarly, a user whose name is Billy and a user whose name is Bryan both belong to a group that has the first letter of their names as “B”, and the user information is registered as such in the phone book. Each user is registered in the phone book so as to belong to one of the groups of group “A” through group “Z”, depending on the first letter of the name of the user. 
         [0356]    Upon starting the phone book data scrolling processing in step S 81 , the control unit  15  determines whether or not the phone book data of a predetermined group determined beforehand is displayed on the display unit  5 . Until determination is made that the phone book data of a predetermined group has been displayed on the display unit  5 , the control unit  15  returns the processing to step S 81 , and continuously executes the scrolling processing of the phone book data described above. 
         [0357]    Conversely, in the case determination is made that the phone book data of a predetermined group is displayed on the display unit  5 , the control unit  15  advances the processing to step S 84 , stops the phone book data scrolling processing, and advances the processing to step S 85 . In step S 85 , the control unit  15  determines whether or not the predetermined time such as 200 msec, for example, has elapsed since the phone book data scrolling processing has been stopped, and in the event determination is made that the predetermined amount of time has elapsed, the control unit  15  advances the processing to step S 86 . 
         [0358]    In step S 86 , by monitoring the operational situation of the display unit  5 , the control unit  15  determines whether or not continuous scrolling operations have been performed by the operator. In the case determination is made that continuous scrolling operations have not been performed by the operator, the control unit  15  advances the processing to step S 87 , stops the phone book scrolling processing, and ends the processing shown in the flowchart in  FIG. 37 . 
         [0359]    Conversely, in the case determination is made in step S 86  that continuous scrolling operations have been performed by the operator, the control unit  15  advances the processing to step S 88 , resumes the phone book data scrolling processing, and returns the processing to step S 83 . In step S 83 , by performing phone book data scrolling processing again, determination is made as to whether or not the phone book data in a predetermined group has been displayed on the display unit  5 , and in the event determination is made that the phone book data in a predetermined group has been displayed on the display unit  5 , operations are performed to stop the phone book data scrolling processing, and these are repeatedly executed. A specific example of the phone book data scrolling processing according to the cellular phone will be described. 
         [0360]      FIG. 38(   a ) through  FIG. 38(   e ) are diagrams showing a situation wherein the phone book data displayed so as to be scrolled on the display unit  5  is subjected to scrolling processing according to the dragging operations by the operator.  FIG. 39(   a ) is a diagram showing the timing to temporarily stop the phone book data scrolling control. 
         [0361]    As an example, as can be seen from  FIG. 39(   a ), in the case of the cellular phone herein, scrolling processing is stopped for a predetermined amount of time at changes in groups. 
         [0362]    That is to say, by performing the scrolling processing, in the case that displays of the phone book data in the group having the initial “A” have passed, and phone book data in the group having the initial “B” is displayed, as shown in  FIG. 38(   a ) and  FIG. 38(   b ), the control unit  15  stops the phone book scrolling processing for a predetermined amount of time at a timing wherein the phone book data in the group having the initial “B” is displayed on the display unit  5 , as shown in  FIG. 39(   a ). 
         [0363]    Also, in the case that, upon the predetermined amount of time having elapsed and the phone book data scrolling processing has resumed, displays of the phone book data in the group having the initial “B” have passed, and phone book data in the group having the initial “C” is displayed, the control unit  15  stops phone book scrolling processing for a predetermined amount of time at a timing wherein the phone book data in the group having the initial “C” is displayed on the display unit  5 . 
         [0364]    Also, in the case that, upon the predetermined amount of time having elapsed and the phone book data scrolling processing has resumed, displays of the phone book data in the group having the initial “C” have passed, and phone book data in the group having the initial “D” is displayed, the control unit  15  stops the phone book scrolling processing for a predetermined amount of time at a timing wherein the phone book data in the group having the initial “D” is displayed on the display unit  5 . 
         [0365]    Thus, each time the phone book data group switches with the scrolling processing, the control unit  15  performs stopping control of the phone book data scrolling processing for a predetermined amount of time. 
         [0366]    Thus, the operator can perform a search of the desired phone book data while visually confirming the group change. Therefore, desired phone book data can be quickly searched from a large number of users. 
         [0367]    The example shown in  FIG. 39(   a ) is an example wherein, in the event that the phone book data group is switched out, the phone book data scrolling processing is stopped for a predetermine amount of time, after the predetermined amount of time has elapsed, the phone book data scrolling processing is resumed according to the dragging operations by the operator. 
         [0368]    An arrangement may be made wherein, according to the scrolling processing as shown in  FIG. 39(   b ), the scrolling speed is gradually slowed down as a change to the phone book data group nears, and the scrolling processing is stopped for a predetermined amount of time at a timing wherein the phone book data group has switched. Upon the predetermined amount of time having elapsed, the scrolling processing may be resumed so as to gradually increase the scrolling speed. Thus, scrolling processing with changes in a natural manner can be performed. 
         [0369]      FIG. 40(   a ) and  FIG. 40(   b ) are diagrams showing a situation wherein the phone book data displayed on the display unit  5  is subjected to scrolling processing according to the flicking operations by the operator.  FIG. 41(   a ) is a diagram showing the phone book data scrolling processing according to the flicking operation strength. 
         [0370]    As an example, as can be seen from  FIG. 41(   a ), in the case that a strong flicking operation is performed, the control unit  15  performs scrolling processing without temporarily stopping at a change in groups, according to the strength of the flicking operation, and in the case that a weak flicking operation is performed, the control unit  15  temporarily stops the scrolling processing at changes in groups. 
         [0371]    To detect the strength or weakness of the flicking operation, the control unit  15  computes “operational distance of flicking operation/flicking operation time”, whereby “operational speed of flicking operation” is computed. In the case that the operational speed herein is faster than the predetermined operational speed (i.e. operational speed serving as a threshold), this means that a strong flicking operation is performed, and in the case that the operational speed herein is slower than the predetermined operational speed, this means that a weak flicking operation is performed. 
         [0372]    Therefore, in the case that the control unit  15  detects a strong flicking operation which is a high speed flicking operation, as shown in  FIG. 40(   a ) and  FIG. 41(   a ), scrolling control of the phone book data corresponding to the strength of the flicking operation is performed, without stopping the switching control at a change in groups. 
         [0373]    Conversely, in the case that the control unit  15  detects a weak flicking operation which is a slow speed flicking operation, as shown in  FIG. 40(   b ) and  FIG. 41(   a ), the phone book data scrolling processing is subjected to stopping control for a predetermined amount of time at changes in groups. 
         [0374]    Thus, when a weak flicking operation is performed, the phone book data scrolling processing is temporarily stopped at a change in groups, whereby the operator can perform a search of a desired still image while recognizing the change in groups. Therefore, an operator can quickly search for desired phone book data from a large number of users. 
         [0375]    Note that by performing the phone data scrolling processing according to the flicking operations of the operator as shown in  FIG. 41(   b ), in the event that a change in groups of phone book data is nearing, the scrolling speed may be gradually decreased and the scrolling processing stopped for a predetermined amount of time at a timing at which the groups are switched. Thus, scrolling processing can be performed with natural changes. 
         [0376]      FIG. 42(   a ) through  FIG. 42(   e ) are diagrams showing a situation wherein the phone book data scrolled on the display unit  5  is subjected to scrolling processing according to the long-pressing operations by the operator.  FIG. 43(   a ) is a diagram showing the timing to temporarily stop the phone book data scrolling processing. 
         [0377]    By performing the phone book data scrolling processing, in the case that displays of the phone book data in the group having the initial “A” have passed, and phone book data in the group having the initial “B” is displayed, as shown in  FIG. 42(   a ) and  FIG. 42(   b ), the control unit  15  stops the phone book data scrolling processing for a predetermined amount of time at a timing wherein the phone book data in the group having the initial “B” is displayed on the display unit  5 , as shown in  FIG. 43(   a ). 
         [0378]    Also, in the case that, upon the predetermined amount of time having elapsed and the phone book data scrolling processing having resumed, displays of the phone book data in the group having the initial “B” have passed, and phone book data in the group having the initial “C” is displayed, the control unit  15  stops phone book data scrolling processing for a predetermined amount of time at a timing wherein the phone book data in the group having the initial “C” is displayed on the display unit  5 . 
         [0379]    Also, in the case that, upon the predetermined amount of time having elapsed and the phone book data scrolling processing having resumed, displays of the phone book data in the group having the initial “C” have passed, and phone book data in the group having the initial “D” is displayed, the control unit  15  stops the phone book scrolling processing for a predetermined amount of time at a timing wherein the phone book data in the group having the initial “D” is displayed on the display unit  5 . 
         [0380]    Thus, each time the phone book data group switches with the scrolling processing, the control unit  15  stops the phone book data scrolling processing for a predetermined amount of time. 
         [0381]    Thus, the operator can perform a search of the desired phone book data while visually confirming the group change. Therefore, desired phone book data can be quickly searched from a large number of users. 
         [0382]    The example shown in  FIG. 43(   a ) is an example wherein, in the event that the phone book data group is switched out, the phone book data scrolling processing is stopped for a predetermined amount of time, and after the predetermined amount of time has elapsed, the phone book data scrolling processing is resumed according to the dragging operations by the operator. 
         [0383]    An arrangement may be made wherein, according to the scrolling processing as shown in  FIG. 43(   b ), the scrolling speed is gradually slowed down as a change to the phone book data group nears, and the scrolling processing is stopped for a predetermined amount of time at a timing wherein the phone book data group has switched. Upon the predetermined amount of time having elapsed, the scrolling processing may be resumed so as to gradually increase the scrolling speed. Thus, scrolling processing with changes in a natural manner can be performed. 
         [0384]    As we can see from the above description, the cellular phone according to the present embodiment has the following advantages. 
         [0385]    1. In the case of performing enlarging processing of still images according to dragging operations, the dragging operations that have been performed continuously are cancelled in the event that the enlarging processing is performed until a predetermined enlarging scale is reached, and the predetermined enlarging scale is maintained. After the predetermined amount of time has elapsed, the enlarging processing according to the dragging operations is resumed. Thus, for example enlarging processing can be stopped for a predetermined amount of time when the still image is at the original size thereof. 
         [0386]    When a still image is subjected to enlarging processing to be larger than the original size, a still image with poor image quality may gradually be displayed. However, by stopping the enlarging processing for a predetermined amount of time, the enlarging processing can be temporarily stopped in the state of displaying a still image (i.e. a still image at the original size) with favorable image quality. 
         [0387]    That is to say, the display scale of the still image can be a variable operation so as to easily change to a display scale having a high probability of being desired by the operator (in this case, the original size of the still image). 
         [0388]    2. In the case of performing enlarging processing of still images according to the flicking operations, the enlarging processing of the still image is performed so that, in the case that a strong flick is performed, the enlargement scale corresponds to the strength of the flicking operation. Conversely, in the case that a weak flick is performed, the enlarging processing is stopped at the enlargement scale of the original size of the still image. 
         [0389]    Thus, in the case of detecting a weak flick, the enlarging processing can be stopped in a state wherein the still image has a favorable image quality (still image at the original size). Therefore, the display scale of the still image can be a variable operation so as to easily change to a display scale having a high probability of being desired by the operator (in this case, the original size of the still image). 
         [0390]    3. In the case of performing enlarging processing of the still image according to long-pressing operations, the continuously performed long-pressing operations are cancelled for a predetermined amount of time in the event that the enlarging processing is performed up to a predetermined enlargement scale, and the predetermined enlargement scale is maintained. After the predetermined amount of time has elapsed, the enlarging processing according to the long-pressing operations is resumed. Thus, the enlarging processing can be stopped temporarily in a state wherein a still image with favorable image quality (i.e. a still image of the original size) is displayed. Therefore, the display scale of the still image can be a variable operation so as to easily change to a display scale having a high probability of being desired by the operator (in this case, the original size of the still image). 
         [0391]    4. In the case of performing enlarging processing of a Web page according to the dragging operations, the dragging operations that have been performed continuously are cancelled in the event that the enlarging processing is performed until a predetermined enlarging scale is reached, and the predetermined enlarging scale is maintained. After the predetermined amount of time has elapsed, the enlarging processing according to the dragging operations is resumed. Thus, for example enlarging processing of a Web page can be stopped temporarily in the event of enlarging text and images on a website to the size desired by a creator. 
         [0392]    That is to say, the display scale of the still image can be a variable operation so as to easily change to a display scale having a high probability of being desired by the operator (in this case, the size of the text and images as desired by the creator of the website thereof). 
         [0393]    5. In the case of performing enlarging processing of a Web page according to the flicking operations, in the case that a strong flicking operation is performed, the enlarging processing of the text and images on the web page is performed so as to be the enlargement scale according to the strength of the flicking operation. Conversely, in the case that a weak flicking operation is performed, the enlarging processing is stopped at an enlargement scale corresponding to the size of the text and images desired by the creator of the Website thereof. 
         [0394]    Thus, in the case of detecting a weak flick, the display scale of the still image can be a variable operation so as to easily change to a display scale having a high probability of being desired by the operator (in this case, the size of the text and images desired by the creator of the Website thereof). 
         [0395]    6. In the case of performing enlarging processing of a Web page according to the long-pressing operations, the dragging operations that have been performed continuously are cancelled in the event that the enlarging processing is performed until a predetermined enlarging scale is reached, and the predetermined enlarging scale is maintained. After the predetermined amount of time has elapsed, the enlarging processing according to the dragging operations is resumed. Thus, for example enlarging processing of a Web page can be stopped temporarily in the event of enlarging text and images on a website to the size desired by a creator. 
         [0396]    That is to say, the display scale of the still image can be a variable operation so as to easily change to a display scale having a high probability of being desired by the operator (in this case, the size of the text and images as desired by the creator of the website thereof). 
         [0397]    7. In the case of performing change control of the playing speed of a music player according to dragging operations, the dragging operations that have been performed continuously are cancelled in the event that the playing speed is changed until a predetermined playing speed is reached, and the predetermined playing speed is maintained. After the predetermined amount of time has elapsed, the change control of the playing speed according to the dragging operations is resumed. Thus, for example change control of the playing speed can be stopped temporarily at the original playing speed of the music. 
         [0398]    That is to say, the music playing speed can be a variable operation so as to easily change to a playing speed having a high probability of being desired by the operator (in this case, the original playing speed of the music). 
         [0399]    8. In the case of changing the music player playing speed according to the flicking operations, in the event a strong flicking operation is detected, the playing speed is changed according to the strength of the flicking operation. Conversely, in the case of detecting a weak flicking operation, the change control of the playing speed is stopped at the original playing speed of the music. 
         [0400]    Therefore, the music playing speed can be a variable operation so as to easily change to a playing speed having a high probability of being desired by the operator (in this case, the original playing speed of the music). 
         [0401]    9. In the case of performing change control of the playing speed of a music player according to long-pressing operations, the long-pressing operations that have been performed continuously are cancelled in the event that the playing speed is changed until a predetermined playing speed is reached, and the predetermined playing speed is maintained. After the predetermined amount of time has elapsed, the change control of the playing speed according to the long-pressing operations is resumed. Thus, for example change control of the playing speed can be stopped temporarily at the original playing speed of the music. 
         [0402]    That is to say, the music playing speed can be a variable operation so as to easily change to a playing speed having a high probability of being desired by the operator (in this case, the original playing speed of the music). 
         [0403]    10. In the case of performing change control of the playing speed of a moving picture player according to dragging operations, the dragging operations that have been performed continuously are cancelled in the event that the playing speed is changed until a predetermined playing speed is reached, and the predetermined playing speed is maintained. After the predetermined amount of time has elapsed, the change control of the playing speed according to the dragging operations is resumed. Thus, for example change control of the playing speed can be stopped temporarily at the original playing speed of the moving picture. 
         [0404]    That is to say, the moving picture playing speed can be a variable operation so as to easily change to a playing speed having a high probability of being desired by the operator (in this case, the original playing speed of the moving picture). 
         [0405]    11. In the case of changing the moving picture player playing speed according to the flicking operations, in the event a strong flicking operation is detected, the playing speed is changed according to the strength of the flicking operation. Conversely, in the case of detecting a weak flicking operation, the change control of the playing speed is stopped at the original playing speed of the moving picture. 
         [0406]    Therefore, the moving picture playing speed can be a variable operation so as to easily change to a playing speed having a high probability of being desired by the operator (in this case, the original playing speed of the moving picture). 
         [0407]    12. In the case of performing change control of the playing speed of a moving picture player according to long-pressing operations, the long-pressing operations that have been performed continuously are cancelled in the event that the playing speed is changed until a predetermined playing speed is reached, and the predetermined playing speed is maintained. After the predetermined amount of time has elapsed, the change control of the playing speed according to the long-pressing operations is resumed. Thus, for example change control of the playing speed can be stopped temporarily at the original playing speed of the moving picture. 
         [0408]    That is to say, the moving picture playing speed can be a variable operation so as to easily change to a playing speed having a high probability of being desired by the operator (in this case, the original playing speed of the moving picture). 
         [0409]    13. In the case of performing switching display control of the still images according to the dragging operations, the dragging operations that have been performed continuously are cancelled for a predetermined amount of time, at breaks between the still images to which time information for the year 2009 is provided and the still images to which time information for the year 2010 is provided, or breaks between folders wherein still images are stored, and the switching display control is stopped for a predetermined amount of time. After the predetermined amount of time has elapsed, the switching display control for the still images according to the dragging operations is resumed. 
         [0410]    Thus, even in the case of performing switching display control with the switching display speed of still images is at a high speed according to the distance of the dragging operations, the switching display control can be stopped for a predetermined amount of time at a break in easily distinguishable groups such as the dates and times that the shots were taken, the storage folders, and the number of images, for example. Therefore, a desired still image can be easily searched for from a large number of still images. 
         [0411]    14. In the case of performing switching display control of the still images according to the flicking operations, in the case that a strong flicking operation is detected, the switching display control of the still images is performed at a speed according to the strength of the flicking operations. Conversely, in the case that a weak flicking operation is detected, the switching display control is stopped at breaks between the still images to which time information for the year 2009 is provided and the still images to which time information for the year 2010 is provided, or breaks between folders wherein still images are stored, or the like. 
         [0412]    Thus, in the case that a weak flicking operation is detected, the switching display control can be stopped for a predetermined amount of time at a break in easily distinguishable groups such as the dates and times that the shots were taken, the storage folders, and the number of images, for example. Therefore, a desired still image can be easily searched for from a large number of still images. 
         [0413]    15. In the case of performing switching display control of the still images according to the long-pressing operations, the long-pressing operations that have been performed continuously are cancelled for a predetermined amount of time, at breaks between the still images to which time information for the year 2009 is provided and the still images to which time information for the year 2010 is provided, or breaks between folders wherein still images are stored, and the switching display control is stopped for a predetermined amount of time. After the predetermined amount of time has elapsed, the switching display control for the still images according to the long-pressing operations is resumed. 
         [0414]    Thus, even in the case of performing switching display control with the switching display speed of still images is at a high speed according to the distance of the long-pressing operations, the switching display control can be stopped for a predetermined amount of time at a break in easily distinguishable groups such as the dates and times that the shots were taken, the storage folders, and the number of images, for example. Therefore, a desired still image can be easily searched for from a large number of still images. 
         [0415]    16. In the case of scrolling control of the phone book data according to the dragging operations, the dragging operations that have been performed continuously are cancelled for a predetermined amount of time, at breaks between various registered users having “A” as the initial and various registered users having “B” as the initial, breaks in groups of company relations or university relations, and so forth, and the scrolling control is stopped for a predetermined amount of time. After the predetermined amount of time has elapsed, the scrolling control for the still images according to the dragging operations is resumed. 
         [0416]    Thus, even in the case of performing scrolling control with the switching display speed of still images at a high speed according to the distance of the dragging operations, the scrolling control can be stopped for a predetermined amount of time at breaks between various registered users having “A” as the initial and various registered users having “B” as the initial, breaks in groups of company relations or university relations, and so forth, and the scrolling control can be stopped for a predetermined amount of time. Therefore, a desired registered user can be searched for from a large number of registered users who are registered in the phone book. 
         [0417]    17. In the case of scrolling control of the phone book data according to the flicking operations, in the case that a strong flicking operation is detected, the phone book data is scrolled at a scrolling speed corresponding to the flicking operation. Conversely, in the case that a weak flicking operation is detected, scrolling control is stopped at breaks between various registered users having “A” as the initial and various registered users having “B” as the initial, breaks in groups of company relations or university relations, and so forth, for example. 
         [0418]    Thus, by performing a weak flicking operation, the scrolling control can be stopped at breaks between various registered users having “A” as the initial and various registered users having “B” as the initial, breaks in groups of company relations or university relations, and so forth. Therefore, a desired registered user can be searched for from a large number of registered users who are registered in the phone book. 
         [0419]    18. In the case of scrolling control of the phone book data according to the long-pressing operations, the long-pressing operations that have been performed continuously are cancelled for a predetermined amount of time, at breaks between various registered users having “A” as the initial and various registered users having “B” as the initial, breaks in groups of company relations or university relations, and so forth, and the scrolling control is stopped for a predetermined amount of time. After the predetermined amount of time has elapsed, the scrolling control for the still images according to the long-pressing operations is resumed. 
         [0420]    Thus, even in the case of performing scrolling control with the switching display speed of still images at a high speed according to the distance of the long-pressing operations, the scrolling control can be stopped for a predetermined amount of time at breaks between various registered users having “A” as the initial and various registered users having “B” as the initial, breaks in groups of company relations or university relations, and so forth, and the scrolling control can be stopped for a predetermined amount of time. Therefore, a desired registered user can be searched for from a large number of registered users who are registered in the phone book.
