Title: Method, apparatus and program for image selection

Description:
BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      The present invention relates to an image selection method and an image selection apparatus for carrying out selection from images displayed on a monitor such as a TV set. The present invention also relates to a program for causing a computer to execute the image selection method.  
      2. Description of the Related Art  
      With use of a DVD player, a movie recorded in a DVD can be reproduced on a household TV set, and music recorded in a CD can be reproduced. By using a DVD player, displaying still image data representing still images recorded in a recording medium such as a DVD or a CD is also becoming a reality. Therefore, if image data obtained by a digital camera or by reading a photographic film are recorded in a recording medium, a user can appreciate images he/she photographed with his/her friends and family by displaying the images on a household TV set.  
      A DVD player having a function of a Web browser used for connection to the Internet has also been provided. In the case where a DVD player has the function of a Web browser, a user can surf the Internet by using a TV set. Furthermore, the user can access a Web site of a DPE store that provides a printing service using image data, and can receive a network printing service such as printing, album generation, and storage regarding still image data he/she obtained.  
      Meanwhile, since a recording medium can record a plurality of still image data sets, a user needs to select a portion of the still image data sets to be reproduced or used for a service in the case where the user wishes to request the service such as printing. Therefore, thumbnail images represented by the still image data sets are generated and displayed as a catalog on a TV set, and the user selects and determines the images by using Left, Right, Up, and Down keys of a remote control of a DVD player.  
      However, image display using a DVD player is often carried out in a comparatively relaxed state, unlike the case of using a personal computer. Therefore, image selection by repetitively pressing small keys on a remote control is troublesome.  
     SUMMARY OF THE INVENTION  
      The present invention has been conceived based on consideration of the above circumstances. An object of the present invention is therefore to enable easy image selection.  
      A first image selection method of the present invention is a method of instructing selection or non-selection regarding a plurality of images, and the first image selection method comprises the steps of:  
      displaying selection status information representing a selection or non-selection state of each of the images being attached thereto when the images are sequentially displayed in predetermined order;  
      displaying one of the images without changing the selection status information of an immediately preceding one of the images in the case where a display instruction thereof has been input within a predetermined time after display of the immediately preceding image, and  
      displaying the image while changing the selection status information of the immediately preceding image in the case where the display instruction has not been input within the predetermined time.  
      A second image selection method of the present invention is a method of instructing selection or non-selection regarding a plurality of images, and the second image selection method comprises the steps of:  
      displaying selection status information representing selection or non-selection of each of the images being attached thereto when the images are sequentially displayed in predetermined order;  
      displaying one of the images while changing the selection status information of an immediately preceding one of the images in the case where a display instruction thereof has been input within a predetermined time after display of the immediately preceding image, and  
      displaying the image without changing the selection status information of the immediately preceding image in the case where the display instruction thereof has not been input within the predetermined time.  
      The predetermined order refers to ascending or descending order of file names, or ascending or descending order of photography date, for example.  
      The selection status information refers to information indicating whether or not an image has been selected. In the first and second image selection methods, the selection status information is attached to the images at the time of display thereof. For example, an icon comprising a circle or an X is attached to the image and displayed together, for respectively indicating that the image has been selected or has not been selected. It is preferable for the selection status information to be described in tag information of image data corresponding to the image.  
      Changing the selection status information refers to changing the selection status information that represent non-selection to represent selection, and to changing the selection status information that represent selection to represent non-selection.  
      In the first and second image selection methods of the present invention, how the selection status information is displayed may be changed before the selection status information is actually changed.  
      Changing how the selection status information is displayed refers to a change for causing a user who carries out image selection instruction to understand the fact that the selection status information is going to be changed. For example, the selection status information may blink or a color thereof may be changed.  
      In the first and second image selection methods of the present invention, a sound may be output for notifying the user of the fact that the selection status information has been changed.  
      A third image selection method of the present invention is a method of instructing selection or non-selection regarding a plurality of images, and the third image selection method comprises the steps of:  
      attaching selection status information to one of the images for representing a selection or non-selection state thereof in the case where an instruction for selecting or not selecting the image is input during display of the image in the course of sequential display of the images in predetermined order, and displaying an immediately following one of the images.  
      In the third image selection method, a sound corresponding to the selection status information to be attached may be output.  
      A first image selection apparatus of the present invention is an apparatus for instructing selection or non-selection regarding a plurality of images, and the first image selection apparatus comprises:  
      an input means for inputting a display instruction regarding an image; and  
      selection means for displaying selection status information representing a selection or non-selection state of each of the images being attached thereto when the images are sequentially displayed in predetermined order,  
      displaying one of the images without changing the selection status information of an immediately preceding one of the images in the case where the display instruction thereof has been input within a predetermined time after display of the immediately preceding image, and  
      displaying the image while changing the selection status information of the immediately preceding image in the case where the display instruction thereof has not been input within the predetermined time.  
      A second image selection apparatus of the present invention is an apparatus for instructing selection or non-selection regarding a plurality of images, and the second image selection apparatus comprises:  
      an input means for inputting a display instruction regarding an image; and  
      selection means for displaying selection status information representing a selection or non-selection state of each of the images being attached thereto when the images are sequentially displayed in predetermined order,  
      displaying one of the images while changing the selection status information of an immediately preceding one of the images in the case where the display instruction thereof has been input within a predetermined time after display of the immediately preceding image, and  
      displaying the image without changing the selection status information of the immediately preceding image in the case where the display instruction thereof has not been input within the predetermined time.  
      In the first image selection apparatus and the and second image selection apparatus of the present invention, the selection means may also be means for changing how the selection status information is displayed before changing the selection status information.  
      In the first image selection apparatus and the second image selection apparatus of the present invention, the selection means may also be means for outputting a sound notifying the fact that the selection status information has been changed.  
      A third image selection apparatus of the present invention is an apparatus for instructing selection or non-selection regarding a plurality of images, and the third image selection apparatus comprises:  
      an input means for inputting an instruction regarding selection of an image; and  
      selection means for attaching selection status information to one of the images for representing a selection or non-selection state thereof in the case where an instruction for selecting or not selecting the image is input during display of the image in the course of sequential display of the images in predetermined order, and for displaying an immediately following one of the images.

      The first to third image selection methods of the present invention may be provided as programs for causing a computer to execute the methods.  
      According to the first image selection method and the first image selection apparatus of the present invention, the images are sequentially displayed in the predetermined order, and the selection status information representing selection or non-selection of the respective images is attached to the corresponding images. In the case where the instruction to display one of the images is input within the predetermined time after the immediately preceding image is displayed, the image is displayed without a change of the selection status information of the immediately preceding image. In the case where the display instruction is not input within the predetermined time, the image is displayed and the selection status information of the immediately preceding image is changed.  
      According to the second image selection method and the second image selection apparatus of the present invention, the images are sequentially displayed in the predetermined order, and the selection status information representing selection or non-selection of the respective images is attached to the corresponding images. In the case where the instruction to display one of the images is input within the predetermined time after the immediately preceding image is displayed, the image is displayed and the selection status information of the immediately preceding image is changed. In the case where the display instruction is not input within the predetermined time, the image is displayed without a change of the selection status information of the immediately preceding image.  
      In this manner, the selection status information is changed if a user who carries out image selection inputs the display instruction or waits for the predetermined time. Therefore, the user can instruct selection or non-selection of the images with only a few operations, and the user is less burdened at the time of image selection.  
      By changing how the selection status information is displayed before changing the selection status information, the user can easily understand that the selection status information is going to be changed regarding the image being displayed.  
      By outputting the sound at the time of selection status information change, the user can easily understand that the selection status information has been changed regarding the image being displayed.  
      According to the third image selection method and the third image selection apparatus of the present invention, the images are sequentially displayed in the predetermined order. At the time of display, if the instruction for selecting or not selecting one of the images is input during the display of the image, the selection status information representing selection or non-selection of the image is attached to the image and the immediately following image is displayed.  
      Therefore, if a user who carries out image selection only instructs selection or non-selection of the image being displayed, the selection status information is attached thereto and the immediately following image is displayed. In this manner, the user can instruct selection or non-selection with only a few operations and the user is less burdened at the time of image selection.  
      By outputting the sound corresponding to the selection status information, the user can easily understand that the image being displayed has been selected or has not been selected.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
      Hereinafter, embodiments of the present invention will be explained with reference to the accompanying drawings.  FIG. 1  is a block diagram showing a configuration of a DVD player as an image selection apparatus of a first embodiment of the present invention. As shown in  FIG. 1 , a DVD player  1  in the first embodiment comprises a media drive  11 , a decoder  12 , a ROM  13 , a RAM  14 , a reception unit  16 , a TV terminal  17 , an input/output terminal  18 , image selection means  21 , and a CPU  19 . The media drive  11  receives insertion of a recording medium M, and reads still image data sets, moving image data sets, audio data sets, and the like recorded in the recording medium M. The decoder  12  decodes the still image data sets, the moving image data sets, and the audio data sets. The ROM  13  stores a program and various information for reproducing the still image data sets, the moving image data sets, and the audio data sets. The RAM  14  temporarily stores the data and is used as a work area. The reception unit  16  receives an instruction from a remote control  15 . The TV terminal  17  is used for connection to a TV set  3  (hereinafter referred to as the TV  3 ). The input/output terminal  18  is used for connecting an external apparatus  31  such as a memory card reader, a hard disc, a printer, or a communication interface, and adopts a standard such as USB or IEEE therefor. The image selection means  21  selects still image data sets S 0  as will be explained later. The CPU  19  controls the media drive  11 , the decoder  12 , the ROM  13 , the RAM  14 , the reception unit  16 , the TV terminal  17 , the input/output terminal  18 , and the image selection means  21 .  
      A personal computer  4  records the still image data sets S 0  obtained by a digital camera  5  in the recording medium M.  
      The still image data sets S 0 , the moving image data sets, and the audio data sets to be recorded in the recording medium M are compressed according to a format such as JPEG or MPEG. The decoder  12  decompresses the still image data sets S 0 , the moving image data sets, and the audio data sets recorded in a compressed state in the recording medium M, and inputs the data to the TV terminal  17  for reproduction thereof. The decoder  12  may be installed for each type of the data such as the still image data sets S 0 , the moving image data sets, and the audio data sets. However, for miniaturization and cost reduction of the apparatus, the decoder  12  is preferably used in common, for the still image data sets S 0 , the moving image data sets, and the audio data sets. During reproduction of the moving image data sets, images and sounds need to be decoded separately. Therefore, it is preferable for the decoders  12  for the images and the decoder  12  for the sounds to be used separately.  
      The ROM  13  stores an operation program for the DVD player  1 . The operation program causes the CPU  19  to carry out data reproduction, and a user can control the operation of the DVD player by using the remote control  15 .  
      Upon data reproduction instruction, a screen for prompting the user to select the data to be reproduced is displayed on the TV  3 , and the media drive  11 , the decoder  12 , and the CPU  19  are driven by the program so as to reproduce the data selected by the user with use of the remote control  15 .  
      For example, in the case where the user inserts the recording medium M having the moving image data sets in the media drive  11  and instructs reproduction of the moving image data sets, the media drive  11  reads the moving image data sets from the recording medium M, and the decoder  12  decodes the moving image data sets. The decoded moving image data sets are output from the TV terminal  17  to be reproduced on the TV  3 .  
      In the case where the user inserts the recording medium M having the still image data sets S 0  in the media drive  11  and instructs reproduction, the media drive  11  reads the still image data sets recorded in the recording medium M, and the decoder  12  decodes the still image data sets S 0 . The decoded still image data sets S 0  are output from the TV terminal  17  and displayed on the TV  3  as still images. In the case where a plurality of the still image data sets are recorded in the recording medium M, thumbnail images of the still image data sets S 0  are displayed and the still image data set S 0  corresponding to a selected one of the thumbnail image is reproduced.  
      In the case where the user inserts the recording medium M having the audio data sets in the media drive  11  and instructs reproduction of the audio data sets, the media drive  11  reads the audio data sets recorded in the recording medium M, and the decoder  12  decodes the audio data sets. The decoded audio data sets are output from the TV terminal  17 , and a sound is reproduced on the TV  3 . The input/output terminal  18  may be connected to a stereo system or a loudspeaker so that the stereo system or the loudspeaker can reproduce the sound.  
      The ROM  13  stores a Web browser. The user can control the Web browser by an instruction from the remote control  15  so as to connect to the Internet  32  via the communication interface  31  connected to the input/output terminal  18 . The user can access a Web site  33  run by a DPE store, and can request a network printing service with the Web site  33  for printing the still image data sets S 0 , for generating a photograph album using the still image data sets, and for storing the still image data sets.  
      Instead of the ROM  13 , a dedicated IC chip may be used for data reproduction and connection to the Internet  32 .  
      The RAM  14  is used for temporary data storage and as a work area.  
      The remote control  15  has Up, Down, Left, and Right, keys  15 A to  15 D and a Determine key  15 E. When the user presses any one of the keys, a signal representing an instruction corresponding to the key is sent to the reception unit  16 .  
      The reception unit  16  receives the signal representing the instruction input by the user with use of the remote control  15 , and inputs to the CPU  19  the instruction for driving the DVD player  1  according to the instruction. The remote control  15  enables all operations of the DVD player  1 , such as reproduction of the still image data sets S 0 , the moving image data sets, and the audio data sets, and image selection as well as various settings, as will be explained later.  
      The image selection means  21  selects a desired portion of the still image data sets S 0  recorded in the recording medium M. Hereinafter, procedures carried out at the time of selection from the still image data sets S 0  will be explained.  FIG. 2  is a flow chart showing the procedures carried out by the first embodiment at the time of selection from the still image data sets S 0 . The recording medium M having the still image data sets S 0  is inserted in the media drive  11 , and a screen for instructing selection and reproduction of the still image data sets S 0  is being displayed on the TV  3 .  
      In the instruction screen, whether or not a still image data selection instruction has been input is judged first (Step S 1 ). If a result at Step S 1  is negative, processing corresponding to an instruction selected in the selection screen is carried out (Step S 2 ) to end the procedures. If the result at Step S 1  is affirmative, the still image data set S 0  having the file name that comes first in the recording medium M is read from the recording medium M (Step S 3 ), and decoded by the decoder  12  (Step S 4 ) to be output from the TV terminal  17  for display on the TV  3  (Step S 5 ).  
       FIG. 3  shows how the still image data set S 0  is displayed on the TV  3 . As shown in  FIG. 3 , an icon  7 A including an X (X) is displayed on the TV  3  in the lower right corner of the still image represented by the still image data set S 0 . The icon  7 A represents the fact that the still image data set S 0  being displayed is in a non-selected state.  
      When the still image is displayed on the TV  3 , a timer is started (Step S 6 ) to judge whether or not a first predetermined time (such as 2.5 seconds) has elapsed since display of the still image data set S 0  (Step S 7 ).  
      If a result at Step S 7  is negative, whether or not an instruction for ending the operation has been input is then judged (Step S 8 ). If a result at Step S 8  is affirmative, the procedures end. If the result at Step S 8  is negative, whether or not the Right key  15 D has been pressed is judged (Step S 9 ) for display of an immediately following one of the images. If a result at Step S 9  is negative, the process returns to Step S 7 . If the result at Step S 9  is affirmative, the still image data set S 0  having the file name that comes immediately after the still image data set S 0  being displayed is read from the recording medium M (Step S 10 ). The process then returns to Step S 4  and the procedures from Step S 4  are carried out to display the following still image data set S 0  on the TV  3 . In the case where the still image data set S 0  whose file name comes last is being displayed, the following image data set S 0  refers to the still image data set S 0  having the file name that comes first.  
      If the result at Step S 7  is affirmative, the icon  7 A blinks (Step S 11 ). Whether or not a second predetermined time (such as 3 seconds) has elapsed after the first predetermined time is then judged (Step S 12 ). If a result at Step s 12  is negative, the process goes to Step S 8  and the procedures from Step S 8  are carried out. If the result at Step S 12  is affirmative, the icon  7 A having the cross is changed to an icon  7 B having a circle (◯), as shown by  FIG. 4 , to indicate that the current still image data set S 0  has been selected (Step S 13 ). An audio message notifying the fact that the still image data set S 0  being displayed has been selected is output (Step S 14 ). The process then goes to Step S 10 , and the procedures from Step S 10  are carried out for display of the following still image data set S 0  on the TV  3 .  
      As has been described above, according to the first embodiment, when one of the still image data sets S 0  is displayed on the TV  3  for selection from the still image data sets S 0 , the following still image data set S 0  is displayed if the Right key  15 D is pressed for not selecting the still image data set S 0  being displayed. In the case where the still image data set being displayed is selected, the still image data set is selected by waiting for the second predetermined time, and the following still image data set S 0  is then displayed. Therefore, the user who carries out selection from the still image data sets S 0  can instruct selection or non-selection regarding the still image data sets S 0  with only a few operations therefor. Consequently, a burden on the user can be reduced at the time of selection.  
      Furthermore, since the icon  7 A blinks before the still image data set S 0  is changed to a selection state, the user can easily understand that the still image data set S 0  being displayed is going to be selected.  
      Moreover, since the audio message is output at the time of selection of the still image data set S 0  being displayed, the user can easily understand the fact that the current still image data set S 0  has been selected.  
      In the first embodiment described above, the icon  7 A having the X is displayed together with the still image data set S 0 , for indicating that the still image data set S 0  being displayed is in the state of non-selection. However, the still image data set S 0  may be displayed together with the icon  7 B having the circle for indicating that the still image data set S 0  being displayed is in the selected state. In this case, the icon  7 B having the circle is changed to the icon  7 A having the X at Step S 13 , and the still image data set S 0  is changed to be in the non-selected state.  
      A second embodiment of the present invention will be explained next. In the second embodiment and a third embodiment that will be explained later, the same elements as in the first embodiment have the same reference numbers, and detailed explanations thereof will be omitted.  FIG. 5  is a flow chart showing procedures carried out in the second embodiment. Whether or not the still image data selection instruction has been input in the instruction screen is judged first (Step S 21 ). If a result at Step S 21  is negative, processing corresponding to the instruction that was input in the instruction screen is carried out (Step S 22 ) to end the operation. If the result at Step S 21  is affirmative, the still image data set S 0  having the file name that comes first is read from the recording medium M by the media drive  11  (Step S 23 ), and decoded by the decoder  12  (Step S 24 ). The still image data set S 0  is then output from the TV terminal  17  and displayed on the TV  3  (Step S 25 ).  
      When the still image data set S 0  is displayed on the TV  3 , the timer is activated (Step S 26 ), and whether or not the first predetermined time (such as 2.5 seconds) has elapsed since display of the still image data set S 0  is then judged (Step S 27 ).  
      If a result at Step S 17  is negative, whether or not the instruction for ending the operation has been input is judged (Step S 28 ). If a result at Step S 28  is affirmative, the operation ends. If the result at Step S 28  is negative, whether or not the Right key  15 D for displaying the following still image data set S 0  has been pressed is judged (Step S 29 ). If a result at Step S 29  is negative, the process returns to Step S 27 . If the result at Step S 29  is affirmative, the icon  7 A having the X is changed to the icon  7 B having the circle for indicating that the still image data set S 0  being displayed has been selected (Step S 30 ). The audio message for notifying that the still image data set S 0  has been selected is output (Step S 31 ), and the following still image data set S 0  whose file name comes next to the file name of the current still image data set S 0  is read from the recording medium M (Step S 32 ). The process then returns to Step S 24  and the procedures from Step S 24  are carried out for display of the following still image data set S 0  on the TV  3 . In the case where the still image data set S 0  whose file name comes last is being displayed, the following still image data set S 0  refers to the still image data set S 0  having the file name that comes first.  
      If the result at Step S 27  is affirmative, the icon  7 A blinks (Step S 33 ), and whether or not the second predetermined time (such as 3 seconds) has elapsed after the first predetermined time is judged (Step S 34 ). If a result at Step S 34  is negative, the process returns to Step S 28  and the procedures from Step S 28  are carried out. If the result at Step S 34  is affirmative, the process returns to Step S 32  and the procedures from Step S 32  are carried out for display of the following still image data set S 0  on the TV  3 .  
      As has been described above, in the second embodiment, when one of the still image data sets S 0  is displayed on the TV  3  at the time of selection from the still image data sets S 0 , the still image data set S 0  being displayed is selected if the Right key  15 D is pressed during the display thereof, and the following still image data set S 0  is then displayed. In the case where the current still image data set S 0  is not selected, the following still image data set S 0  is displayed after the second predetermined time has elapsed with no operation. Therefore, a user who carries out selection from the still image data sets S 0  can instruct selection or non-selection of the still image data sets with only a few operations. Consequently, the user is less burdened at the time of selection.  
      In the first and second embodiments described above, the still image data set S 0  having the file name that comes immediately before the file name of the current still image data set S 0  can be displayed by pressing the Left key  15 C. At this time, the still image data set S 0  has already been attached with the icon  7 A or  7 B representing the selected or non-selected state thereof. In this state, by pressing the Up or Down key  15 A or  15 B, selection or non-selection of the still image data set S 0  can be changed from one to the other.  
      The third embodiment of the present invention will be explained next.  FIG. 6  is a flow chart showing procedures carried out in the third embodiment. Whether or not the still image data selection instruction has been input in the instruction screen is judged first (Step S 41 ). If a result at Step S 41  is negative, the processing corresponding to the instruction that was input in the instruction screen is carried out (Step S 42 ) to end the operation. If the result at Step S 41  is affirmative, the still image data set S 0  having the file name that comes first is read from the recording medium M by the media drive  11  (Step S 43 ), and decoded by the decoder  12  (Step S 44 ). The still image data set S 0  is then output from the TV terminal  17  to be displayed on the TV  3  (Step S 45 ).  
       FIG. 7  shows an image represented by the still image data set S 0  displayed on the TV  3 . As shown in  FIG. 7 , an icon  7 C having a question mark (?) is displayed in the lower right corner of the still image. The icon  7 C represents the fact that selection or non-selection of the current still image data set S 0  has not been instructed. Whether or not the Right key  15 D has been pressed is then judged (Step S 46 ). If a result at Step S 46  is affirmative, information representing non-selection of the current still image data set S 0  is attached to the current still image data set S 0  (Step S 47 ), and an audio message indicating non-selection is also output (Step S 48 ). The information representing non-selection is described in tag information of the still image data set S 0 .  
      The still image data set S 0  having the file name that comes immediately after the file name of the current still image data set S 0  is read from the recording medium M (Step S 49 ), and the process returns to Step S 44 . The procedures from Step S 44  are then carried out, and the following still image data set S 0  is displayed on the TV  3 . In the case where the current still image data set S 0  has the file name that comes last, the still image data set S 0  whose file name comes first is displayed as the still image data set S 0  having the file name that comes immediately after the file name of the current still image data set S 0 .  
      If the result at Step S 46  is negative, whether or not the Determine key  15 E has been pressed is then judged (Step S 50 ). If a result at Step S 50  is affirmative, information is attached to the currently displayed still image data set S 0  for representing selection thereof (Step S 51 ). An audio message indicating the selection is also output (Step S 52 ). The audio message output at Step S 52  is different from the audio message output at Step S 48 . The process then returns to Step S 49  for display of the following still image data set S 0 , and the procedures from Step S 49  are carried out. The following still image data set S 0  is therefore displayed.  
      If the result at Step S 50  is negative, whether or not the instruction for ending the operation has been input is judged (Step S 54 ). If a result at Step S 54  is affirmative, the operation ends. If the result at Step S 54  is negative, the process returns to Step S 46 , and the procedures from Step S 46  are carried out.  
      As has been described above, according to the third embodiment, when one of the still image data sets S 0  is displayed on the TV  3  at the time of selection from the still image data sets S 0 , the following still image data set S 0  having the file name that comes next to the file name of the currently displayed still image data set S 0  is displayed if the Right key  15 D is pressed during the display thereof, for not selecting the current still image data set S 0 . In the case where the current still image data set S 0  is to be selected, the current still image data set S 0  can be selected by pressing the Determine key  15 E, and the following still image data set S 0  is then displayed. Therefore, a user who carries out selection from the still image data sets S 0  can instruct selection or non-selection of the still image data sets with only a few operations. Consequently, the user is less burdened at the time of selection.  
      Moreover, since the audio message is output at the time of selection of the still image data set S 0  being displayed, the user can easily understand that the still image data set S 0  being displayed is in the selection state.  
      In the third embodiment, the still image data set S 0  having the file name that comes immediately before the file name of the current still image data set S 0  can be displayed by pressing the Left key  15 C. At this time, the icon  7 A or  7 B representing selection or non-selection, or icon  7 C representing that selection or non-selection has not been instructed is shown together with the still image data set S 0 . By pressing the Up or Down key  15 A or  15 B in this state, selection or non-selection of the still image data set S 0  can be changed from one to the other.  
      In the first to third embodiments described above, the still image data sets S 0  that have been selected are sent from the communication interface  31  connected to the input/output terminal  18  to the Web site  33  of the DPE store via the Internet  32 , and are used for various kinds of printing services therein.
