           [0002]    The present invention relates to an electronic camera.  
           [0003]    2. Description of Related Art  
           [0004]    In the field of electronic cameras for converting a photographed image into a digital image and recording the digital image on a recording medium, such as a memory card, there is widely known a camera in which information related to photographing, such as date, can be recorded with respect to each photographic film frame.  
           [0005]    In the conventional electronic camera, however, the information related to photographing is generally entered using a switch, command dial or the like, which does not necessarily ensure a high operating efficiency. Further, the switch, command dial or the like needs to be additionally provided, or a switch having other function needs to be shared for the above purpose.  
         SUMMARY OF THE INVENTION  
         [0006]    An object of the present invention is to provide an electronic camera provided with data entry function by means of a pen-type designator.  
           [0007]    To accomplish the above object, an electronic camera according to one aspect of the present invention comprises: an imaging element that forms an image of an object; a display device that displays the formed image; a memory that stores the image formed by the imaging element; and a designating device that designates arbitrary positions on a display screen of the display device.  
           [0008]    An electronic camera according to another aspect of the present invention comprises: an imaging element that converts an optical image that passes through a photographing lens into a digital image by operating a release switch to an ON state; a display device capable of displaying the digital image; a pen-type designator capable of designating an arbitrary position on a display screen of the display device; a pen position detecting device that detects the position designated by the pen-type designator; a pen trail display controller that causes the display device to display a movement trail of the detected designated position; and a pen detection controller that inhibits the imaging element from forming an image of a next frame and allows the pen position detecting device to detect the designated position and allows the pen trail display controller to control display of the movement trail, while the release switch is kept operated to the ON state after the imaging element terminates forming an image of one frame, the pen detection controller enabling the imaging element to effect forming an image of the next frame when the release switch is thereafter operated to an OFF state.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0020]    First Embodiment  
         [0021]    There will be described the first embodiment of the present invention, referring to FIG. 1A through FIG. 3.  
         [0022]    [0022]FIGS. 1A and 1B are perspective views of an electronic camera having the pen input function, as viewed from the back side and the front side of the camera, respectively. In FIG. 1A, a pen input detecting portion  2  consists of a touch panel (touch tablet) and others. As known in the art, the touch panel consists of two layers of transparent electrodes and detects the position of a pressed point at which the two electrode layers are in contact with each other, or detects the position of a contact point by detecting a change in the capacitance at the point. Display portion  4  is positioned inside the pen input detecting portion  2  (the side toward the front side of the camera). The display portion  4  consists of a liquid crystal display (LCD), for example, and a camera user can view a display screen of the display portion  4  from the back side of the camera, through the pen input detecting portion  2 .  
         [0023]    Select switch  7  is operated to select one of the following modes: a photographing mode in which an object is photographed, a pen input mode that permits data entry with a pen, and a reproduction mode in which the display portion  4  displays photographed image data that are recorded in a memory portion  6  or detachable PC card memory portion  6  which will be described later. When the select switch  7  is operated to the pen input mode, a trail of a pen-shaped pointer  3  is superposed on the photographed image, and outputted on the display portion  4  in real-time operation. Thus, desired data can be entered through the pen-shaped pointer  3  as if they were drawn with ink. If the select switch  7  is operated to the photographing mode, an image of an object obtained through a photographing lens  11  (FIG. 1B) appears in the display portion  4 . If a release button  12  is pressed in this condition, the image that appears at this moment is recorded in the memory portion  6 . In the case where a background is dark, flash light is emitted by an electronic flash device (strobe)  13  (FIG. 1B).  
         [0024]    [0024]FIG. 2 is a block diagram showing the construction of a main portion of the electronic camera of FIG. 1A and FIG. 1B. Where the selector switch  7  is operated to the photographing mode, the imaging portion  1  starts forming an image when the release button  12  is half pressed, and the image taken by the photographing lens  11  is converted into electric signals by means of CCD (photoelectric converting device) that is not shown in the figure, and received by a control portion  5  that performs image processing and others, through a sampling hold circuit and AD converter that are not shown in the figure. The control portion  5  incorporates a buffer (not shown) for temporarily storing the image that has been just photographed, and displays the image in the display portion  4 . The control portion  5  also performs image processing, such as JPEG compression, with respect to an image taken at the point of time when the release button  12  is fully pressed, and the processed image is recorded in the memory portion  6 . The control portion  5  consists of a microprocessor and peripheral equipment, and performs the above-described image processing and other controls of the electronic camera.  
         [0025]    Where the select switch  7  is operated to the reproduction mode, the control portion  5  reads the image recorded in the memory portion  6 , and displays the image in the display portion  4 . Where the select switch  7  is operated to the pen input mode, the movement trail of the pen detected by the pen input detecting portion  2  is displayed in the display portion  4  irrespective of whether the photographed image is displayed in the display portion  4  or not. When the photographed image is displayed in the display portion  4 , therefore, the trail of the pen-shaped pointer  3  is displayed as it is superposed on the photographed image.  
         [0026]    The electronic camera of the present embodiment as described above is often used in a manner in which information related to photographing of one frame is entered through the pen-shaped pointer  3  after completion of photographing with respect to that frame. In such cases, however, it takes trouble to operate the select switch  7  each time photographing is followed by pen data entry and pen data entry is followed by photographing. In view of this, a control routine of FIG. 3 is executed in the present embodiment so as to save trouble in operating the select switch  7 .  
         [0027]    [0027]FIG. 3 is a flow chart showing a part of the operation of the electronic camera when the select switch  7  is operated to the photographing mode. The operation of the first embodiment will be described referring to this flow chart. In step S 1  of FIG. 3, an initial screen is displayed in the display portion  4  when a power supply switch of the electronic camera is turned on, while waiting for the release button  12  to be operated. In step S 1 A, it is determined whether the release button  12  is half pressed or not. The control flow goes to step S 1 B when the button  12  is half pressed, and stays in step S 1 A if the button  12  is not half pressed. Namely, this step S 1 A indicates that the camera is on standby for the operation of the camera user. Even if the release button  12  is fully pressed at a time, these steps are executed since the button  12  must go through a half-pressed state.  
         [0028]    In step S 1 B, the imaging portion  1  starts forming an image of an object, and the formed image is converted into a digital image and then displayed in the display portion  4 . At this time, the display portion  4  functions as a view finder. In step S 2 , it is determined whether the release button  12  is fully pressed (a release switch is turned on, in other words release is ON) or not. The control flow stays at step S 2  if the release switch is in the OFF state, and goes to step S 3  if the switch is turned ON. In step S 3 , a release flag is set to ON. This release flag is a flag for judging whether pen data entry is acceptable or not, and the ON state of this flag indicates that the pen data entry is acceptable. And also, this release flag is maintained in the ON state while the release button  12  is being pressed, and placed in the OFF state once a hand is released from the release button  12 .  
         [0029]    In step S 4 , the digital image of the object image taken at the point of time when the release switch is turned ON is obtained and fixed by the control portion  5 , and the fixed digital image is displayed in the display portion  4  in step S 5 . In step S 6 , the obtained and fixed digital image is subjected to image compression processing in the control portion  5 , and the result is recorded in the memory portion  6  in step S 7 .  
         [0030]    In step S 8 , it is determined whether the above-described release flag is ON or not. The control flow goes back to step S 1  when the flag is OFF, and goes to step S 9  when the flag is ON. The ON state of the release flag indicates that the release button  12  is kept pressed even after the release switch is turned ON. In this case, the pen input processing is effected by executing steps S 9 -S 14  as described below.  
         [0031]    In step S 9 , the pen input function is turned ON. More specifically, a signal is fed to the pen input detecting portion  2 , to start processing for detecting coordinate positions at which the user enters data with a pen or the like. In step S 10 , characters or others entered with the pen are converted into image data based on the coordinate positions detected by the pen input detecting portion  2 , and displayed such that the image data are superposed on photographed image data that are currently displayed. In step S 11 , it is determined again whether the release flag is ON or not. This determination is made in order to determine whether data entry with the pen has been completed or not. Since the release flag is turned OFF at the point of time when the user releases his/her hand from the release button  12  after the pen data entry is finished, it is possible to know whether the pen data entry is finished or not by detecting whether the release flag is ON or not.  
         [0032]    If it is determined in step S 11  that the release flag is ON, the control flow goes back to step S 10  to continue detection of the trail of the pen-shaped pointer  3 . If it is determined that the release flag is OFF, the control flow goes to step S 12  to turn OFF the pen input function. As a result, the pen input detecting portion  2  stops detecting the pen coordinate positions. In step S 13 , the image data entered through the pen-shaped pointer  3  is compressed by the control portion  5 , and the compressed data is stored in the memory portion  6  in step S 14 .  
         [0033]    When the pen input data are stored in the memory portion  6  in step S 14 , the input data are related to the photographed image data previously stored in the memory portion  6 . Where the photographed image data is given a name “950831000010”, for example, the pen input data may be given a file name “950831000011”. With the pen input data related to the photographed image data, both of these data can be superposed on each other again and displayed when they are reproduced later or when the data are transferred to an external computer to be further processed. Upon completion of the processing of step S 14 , the control flow goes back to step S 1  and then proceed to step S 1 A to place the camera on standby for the operation by the user. Namely, the initial screen is displayed on the display device  4  while waiting for the operation to half press the release button  12 .  
         [0034]    In the first embodiment as described above, the camera user can utilize the pen input function to arbitrarily enter trails directed by the pen-shaped pointer  3 , such as handwritten characters or drawings, thus making it possible for the electronic camera to receive a wide variety of information.  
         [0035]    Where the release button  12  is kept fully pressed after the release button  12  is fully pressed, the camera is automatically switched to a condition in which data can be entered with the pen, thus eliminating a need to operate the select switch  7  to switch the modes before the data entry is effected. As a result the operability is improved. Further, the pen input function is automatically turned OFF once the user releases the hand from the release button upon completion of the data entry with the pen, thus allowing the user to prepare for the next photographing immediately after the pen data entry, and eliminating a possibility of missing a chance to release the shutter. Namely, according to the first embodiment, the pen input function can be selectively turned ON or not by selecting whether the release button  12  that is always operated upon photographing is kept operated or not, thereby eliminating a possibility for the user to hesitate as to how to operate, and thus assuring improved operating efficiency. While the pen is employed as input means, it may be replaced by other input means, such as a trackball or a mouse.  
         [0036]    Second Embodiment  
         [0037]    In the second embodiment, the pen input function is automatically set to the ON state when photographed image data that have been photographed and stored in a memory, a memory card or the like are reproduced. The construction of the second embodiment is the same as that of the first embodiment, and thus will not be explained. In the following, the operation of the second embodiment will be described referring to a flow chart of FIG. 4. In this embodiment, the power supply of the electronic camera is turned ON while the select switch  7  is placed in the reproduction mode.  
         [0038]    In step S 51  of FIG. 4, when the power supply switch of the electronic camera is turned ON, photographed image data which correspond to a plurality of frames among photographed image data stored in the memory portion  6  are displayed on the display portion  4  at the same time in order starting from the latest photographed image data, while waiting for the release button  12  to be operated. Namely, this step S 51  indicates that the camera is on standby for a command for reproduction. In this step S 51 , the photographed image data of respective frames are displayed in reduced size (so-called thumbnail display) so that the image data corresponding to the plurality of frames can be displayed at the same time.  
         [0039]    In step S 52 , it is determined whether the release button  12  is fully pressed (the release switch is turned ON) or not. The control flow stays at step S 52  if the release switch is OFF, and goes to step S 53  if the switch is turned ON. In step S 53 , the release flag is set to ON. In step S 54 , the latest frame (that has been photographed most lately) is determined as a frame to be reproduced, and the photographed image data corresponding to this frame is retrieved from the memory portion  6 . In step S 55 , the latest photographed image data is displayed in enlargement over the entire display screen of the display portion  4 .  
         [0040]    In step S 56 , it is determined whether a predetermined period of time (e.g., 1 to 2 seconds) has elapsed since the reproduction display started in step S 54 . Upon a lapse of the predetermined time, the control flow goes to step S 57  to determine whether the release flag is ON or not. Where the release flag is ON, which means that the release button  12  is kept being pressed, the control flow goes to step S 58  to actuate the pen input function, and steps S 58  to S 63  are subsequently executed to effect the same processing as conducted in steps S 9  to S 14  of FIG. 3.  
         [0041]    In this manner, the photographed image data that are currently reproduced are displayed such that the image data entered with the pen-shaped pointer  3  are superposed on the photographed image data, and the photographed image data that are being reproduced and the pen input image data are stored in the memory portion  6  such that these data are correlated with each other. When the photographed image data and pen input image data are displayed as they are superposed on each other, these two kinds of data are handled independently of each other, thus avoiding loss of independence of the data even if they are superposed on each other and displayed.  
         [0042]    Thus, in the second embodiment, various kinds of image information related to the photographed image data that are being reproduced can be entered with the pen-shaped pointer  3 , and stored in the memory portion  6  or the like such that the input image data thus entered are correlated with the photographed image data. Further, the select switch  7  need not be operated by the operator since the pen input function can be actuated only by keeping the release button  12  pressed.  
         [0043]    Third Embodiment  
         [0044]    The third embodiment permits switching of respective modes, i.e., pen input mode, photographing mode and reproduction mode, without providing the select switch  7  shown in FIG. 1A.  
         [0045]    FIGS.  5  to  9  are rear elevational views of an electronic camera according to the third embodiment. The same reference numerals as used in FIG. 1A are used for identifying corresponding elements. As shown in FIG. 5, the electronic camera of the third embodiment does not have the select switch  7  shown in FIG. 1A, but instead includes touch switches for effecting switching of various modes. The touch switches are constructed by combining the pen input detecting portion  2  with the display portion  4  and a display sheet representing the functions of the switch that are provided below the detecting portion  2 . It is to be noted that the release button  12 , recording switch  13  and a power supply switch that is not shown are provided in the form of mechanical switches as used in the first embodiment, rather than in the form of touch switches. The electronic camera of the third embodiment is provided with an optical finder  14  that is located apart from the display portion  4 . A block diagram showing the construction of the main portion of the electronic camera is the same as that of FIG. 2, except for the absence of the select switch  7  and addition of the recording switch  13 .  
         [0046]    As shown in FIG. 5, the display portion  4  and a sheet in which are printed a picture representing “scroll bars”, characters that read “MENU”, characters that read “DEFINED” and characters that read “CLEAR” are provided below the pen input detecting portion  2 . The display portion  4  consists of a liquid crystal display (LCD) as used in the first embodiment, for example. The printed sheet is combined with respective portions of the pen input detecting portion  2  that correspond to items printed in the sheet, so as to provide touch switches of scroll bars  21 - 24 , MENU button  25 , DEFINED button  26  and CLEAR button  27 . For example, if the scroll bar  22  is pressed by the pen-shaped pointer  3 , the image data in the display portion  4  is scrolled upwards. To the contrary, the image data in the display portion  4  is scrolled downwards if the scroll bar  23  is pressed by the pen-shaped pointer  3 . If the scroll bar  21  is pressed by the pen-shaped pointer  3 , on the other hand, the top image data is displayed in the display portion  4 , and if the scroll bar  24  is pressed by the pen-shaped pointer  3 , the last image data is displayed in the display portion  4 . In this connection, the pen input detecting portion  2  detects the position of a point pressed by the pen-shaped pointer  3  based on the pressure applied to the point. It is therefore possible to actuate the MENU button  25 , DEFINED button  26 , CLEAR button  27  and others that have somewhat large areas, by pressing these buttons with fingers or the like having some areas.  
         [0047]    While the touch switches are constituted by the combination of the sheet on which the scroll bars  21 - 24 , MENU button  25 , DEFINED button  26  and CLEAR button  27  are printed, and the pen input detecting portion  2 , the size of the display portion  4  may have the size corresponding to the entire area of the pen input detecting portion  2 , and the contents printed as described above may be displayed on the display portion  4  so as to provide the touch switches.  
         [0048]    When the menu button  25  is pressed, the display screen  5  displays a screen as shown in FIG. 5 that allows selection of modes. In this display, indications  28 - 30  represent touch switches  28 - 30  for selecting respective modes, which switches consist of the indications and portions of the pen input detecting portion  2  that correspond to these indications. In this condition, if any one of the touch switches  28 - 30  in the display portion  4  is selected by the pen-shaped pointer  3  and the DEFINED button  26  is pressed, the selected mode is stored in the memory portion  6  or the like, and the mode is switched to the selected one. To the contrary, the selection is cancelled if the CLEAR button  27  is pressed.  
         [0049]    The modes displayed when the MENU button  25  is pressed include those as shown in FIG. 5. While the selectable modes are displayed in FIG. 5 in the form of characters that read “RECORD”, “REPRODUCTION” and “SETTING”, these characters may be replaced by icons as described below which hint the contents of the modes.  
         [0050]    (1) RECORD mode (icon display representing camera or video camera or the like, microphone, and pen)  
         [0051]    (2) REPRODUCTION mode (icon display representing television, speaker and pen)  
         [0052]    (3) SETTING mode (icon display representing switch)  
         [0053]    Each of the above modes may be established by selecting the corresponding one in the above-described menu screen. Otherwise, the RECORD mode may be unconditionally established when the power supply is turned on, and any mode may be switched to a photographed image record mode as described later if the release button is half pressed. It is also possible to display in the screen a menu icon selected for switching whichever mode to the photographed image record mode without operating the release button.  
         [0054]    There will be next described each of the modes. FIG. 10 is a view explaining the whole construction of the respective modes.  
         [0055]    (1) RECORD Mode  
         [0056]    The RECORD mode is unconditionally established whenever the power supply switch of the electronic camera is pressed. The RECORD mode is further subdivided into three subordinate modes, i.e., (A1) photographed image record mode, (B1) note input mode, and (C1) sound-recording mode.  
         [0057]    (A1) Photographed Image Recording Mode  
         [0058]    This mode is established by operating the release button  12 . Initially, the release button  12  is half pressed, and the display portion  4  starts displaying an image that has been formed (the timing in which the display portion  4  starts displaying can be changed as described later). If the release button  12  is fully pressed, the photographed image data are recorded in the memory portion  6 . Thereafter, the photographed image data are kept displayed in the display portion  4  while the release button  12  is kept pressed (including both states in which the button is half pressed and fully pressed), and various information can be entered with the pen-shaped pointer  3  during that period of time. Once a hand is released from the release button  12 , the image data entered with the pen and the photographed image data are recorded in the memory portion  6  such that these data are correlated with each other. If the CLEAR button  27  is pressed while the release button  12  is pressed, the display portion  4  displays a screen which requests selection of whether only the photographed image data are to be deleted, or only the pen input image data are to be deleted, or both of the image data are to be deleted. If any one of these is selected, the selected data are deleted from the display portion  4 . In the SETTING mode as described later, it is possible to change from a single-shot mode to a serial-shot mode and vice versa. If the serial-shot mode is selected, pictures are serially taken while the release button  12  is fully pressed. Data cannot be entered with the pen while the pictures are serially taken.  
         [0059]    In the SETTING mode can be also selected a setting in which the pen input mode is established for a predetermined period of time (e.g., 30 sec.) after the release button  12  is released or until the release button is half pressed next time, after the release button is fully pressed in the single-shot mode and the photographed image data are recorded. If the photographed image record mode is established, the image can be recorded by pressing the DEFINED button  26  of FIG. 5 with the pen in the same way in which the image is recorded by fully pressing the release button.  
         [0060]    (B1) Note Input Mode  
         [0061]    If a portion of the pen input detecting portion  2  that corresponds to a predetermined region of the display portion  4  is pressed by the pen-shaped pointer  3  after the power supply switch of the electronic camera is turned ON, the note input mode is established, and a palette (black, white, red) showing pen display colors is displayed at one corner of the screen. If the operator selects one of the colors in this palette, note data can be entered with the selected color. If the CLEAR button  27  is pressed, a screen is displayed again which confirms whether the note (pen input image data) is to be deleted or not, and the note is deleted after the confirmation. On the other hand, the note that has been entered is stored in the memory portion  6  at the point of time when the DEFINED button  26  is pressed. In the above-described note input mode, the photographed image or reproduced image is not displayed, and the note is entered with a blank background. In the SETTING mode as described later, it is also possible to set so as to automatically display the latest reproduced image as the back ground at the point of time when the note input mode is selected. In this case, the note thus entered is stored in the memory portion  6 , such that the note is correlated with the reproduced image displayed as the background.  
         [0062]    (C1) Sound-recording Mode  
         [0063]    The sound-recording mode is established if the recording button  13  shown in FIG. 5 is pressed. Pictures can be taken during sound recording or after the sound recording for a predetermined time. It is also possible to record sound after taking pictures to the contrary. Recorded voice or other sound can be recorded in the memory portion  6  such that the voice is correlated with the image taken at the same time as the recording. It is, however, impossible to record voice between film frames used for photographing (regardless of the frames).  
         [0064]    The recording mode is further subdivided into four subordinate modes as follows, and an appropriate mode is selected in the SETTING mode as described later.  
         [0065]    (1) Mode in which sound is recorded while the recording button  13  is being pressed.  
         [0066]    (2) Mode in which the sound recording is started when the recording button  13  is pressed once, and is stopped when the button is pressed again.  
         [0067]    (3) Mode in which the sound recording is started when the recording button  13  is pressed only for a moment, and is terminated when the button is pressed again for a moment, while the recording continues during a period of time in which the recording button  13  is being pressed.  
         [0068]    (4) Mode in which photographing is effected once the release button is pressed, and the sound recording continues during a period of time in which the release button is being pressed.  
         [0069]    (2) REPRODUCTION Mode  
         [0070]    The REPRODUCTION mode is established when the switch  29  for the REPRODUCTION mode, which is displayed when the MENU button  25  is pressed by the pen-shaped pointer  3 , is pressed by the pen-shaped pointer  3 . The REPRODUCTION mode is further subdivided into (A2) image reproducing mode, (B2) note reproducing and recording mode, and (C2) sound reproducing mode. If the REPRODUCTION mode is established, the display as shown in FIG. 6 or FIG. 7 is provided. FIG. 9 is a view showing in enlargement the pen input detecting portion  2  and display portion  4  of FIG. 7.  
         [0071]    (A2) Image Reproducing Mode  
         [0072]    Initially, the photographed image data that have been photographed and stored in the memory portion  6  are displayed in thumbnail form (displayed in reduced size) (reference numeral  31  in FIG. 9). If it takes time to provide the thumbnail display, a given symbol (“*” mark, for example) is displayed (reference numeral  32  in FIG. 9) for the moment, and the “*” mark for the image data that are ready to be displayed in the thumbnail form is then deleted and replaced by the thumbnail display, in the order in which the preparation for the thumbnail display is completed.  
         [0073]    If the photographed image data corresponding to one frame is to be reproduced and displayed over the entire area of the display portion  4 , a selected one of the regions in which the thumbnail display is provided or a selected one of the “*” marks is pressed by the pen-shaped pointer  3 . Thus, the thumbnail image is positively displayed, causing the operator to recognize selection of the image data. If the operator then presses the DEFINED button  26  with the pen-shaped pointer  3 , the photographed image corresponding to the selected thumbnail image is displayed over the entire area of the display portion  4 .  
         [0074]    If the photographed image data corresponding to four frames (FIG. 8) or nine frames are to be reproduced and displayed in the display screen  4 , on the other hand, the thumbnail images or “*” marks corresponding to the four frames or nine frames are traced by the pen-shaped pointer  3 , and the DEFINED button  29  is pressed so that the photographed images corresponding to the four frames (FIG.  8 ) or nine frames are displayed in divided areas over the entire display region of the display portion  4 . In this condition, if one of the photographed images displayed in the divided areas is touched by the pen-shaped pointer  3 , and the DEFINED button  26  is pressed, the selected photographed image is displayed over the entire display region of the display portion  4 .  
         [0075]    When a part of the pen input detecting portion  2  that corresponds to a certain region of the display portion is pressed by the pen-shaped pointer  3  while the photographed image on one frame is displayed in the display portion  4 , a note can be entered with a pen, namely, a note can be written or drawn on the displayed photographed image. If the DEFINED button  26  is then pressed, the note is recorded as appended to the photographed image.  
         [0076]    If the scroll bar  22  in the pen input detecting portion  2  is pressed by the pen-shaped pointer  3  while the photographed image on one frame is displayed in the displayed portion  4 , the photographed image on a frame just before the above-indicated one frame is displayed. If the scroll bar  23  is pressed by the pen-shaped pointer  3 , on the other hand, the photographed image on a frame just after the above-indicated one frame is displayed. If the scroll bar  21  is pressed by the pen-shaped pointer  3 , the photographed image of the oldest frame that has been recorded in the memory portion  6  is displayed. If the scroll bar  24  is pressed by the pen-shaped pointer  3 , the photographed image of the latest frame is displayed.  
         [0077]    The photographed image data recorded in the memory portion  6  are deleted in the following manner. Initially, a part (one frame or a plurality of frames) of photographed images on a plurality of frames that are displayed in thumbnail form is selected by the pen-shaped pointer  3 . As a result, the photographed image(s) on the selected one or plural frame(s) is/are negatively displayed (though not limited to the negative display if the image(s) can be distinguished from the other images). If the operator presses the CLEAR button  27  in this condition, the photographed image data corresponding to the selected frame(s) are deleted. When the image data in the memory portion  6  are deleted, it can be set whether only the photographed image data are to be deleted, or only the note (pen input image data) are to be detected, or both of these data are to be deleted.  
         [0078]    (B2) Note Reproducing and Recording Mode  
         [0079]    The note entered with the pen is reproduced such that it is superposed on the photographed image data related to the note. Another note may be entered in this condition. If the CLEAR button  27  is pressed, on the other hand, a screen is displayed to confirm whether the note is to be deleted or not, and the note is deleted after confirmation. The noted entered is stored in the memory portion  6  if the DEFINED button  26  is pressed. It is to be noted that a picture is not taken even if the release button  12  is fully pressed while the note is being entered.  
         [0080]    (C2) Voice Reproducing Mode  
         [0081]    When the reproduction mode is established, a screen as shown in FIG. 9 is displayed in the display portion  4 . The photographed image is displayed in thumbnail form by the side of the time when the relevant picture was taken, and a bar graph representing voice is displayed by the side of the thumbnail display. If the DEFINED button  26  is pressed after the bar graph representing voice is pressed by the pen-shaped pointer  3 , the voice is reproduced. The range that is pressed by the pen-shaped pointer  3  is kept reversed (the reversed display is not necessarily provided if it can be distinguished from the other bar graphs), and the reversed state is maintained unless another button or bar graph is pressed by the pen-shaped pointer  3 , thus enabling the voice in the same portion to be reproduced any number of times by pressing the DEFINED button  26 .  
         [0082]    If the recording button  13  is pressed in the reproduction mode, the voice of the next bar graph is reproduced. It is also possible to serially reproduce a plurality of voices by pressing bar graphs representing these voices with the pen-shaped pointer  3 . If the voice and image are to be reproduced at the same time, the DEFINED button  26  is pressed after the thumbnail image and the bar graph for the voice are pressed by the pen-shaped pointer  3 . If the CLEAR button  27  is pressed while the bar graph is being reversed, the voice corresponding to the reversed bar graph is erased. In FIG. 9, the length of the bar graph is varied depending upon the recording time so that the recording time of the recorded voice can be recognized at a glance.  
         [0083]    (3) SETTING Mode  
         [0084]    When the MENU button  25  is pressed by the pen-shaped pointer  3 , a switch  30  for the SETTING mode is displayed as shown in FIG. 5, and the SETTING mode is established if this switch  30  is pressed by the pen-shaped pointer  3 . The SETTING mode is subdivided into eight subordinate modes, i.e., (A3) serial-shot setting mode, (B3) flash setting mode, (C3) image quality setting mode, (D3) LCD display mode, (E3) time setting mode, (F3) information display mode, (G3) sound-recording operation setting mode, and (H3) volume control mode. If the SETTING mode is selected, these modes are displayed in the display portion  4 . Each of the above modes can be set by pressing with the pen an icon of a toggle switch displayed in the display portion  4 . While the toggle switch is displayed in the form of the icon, this toggle switch may be merely represented by “O” when it is displayed. There are also displayed switches that correspond to respective items as explained below. Each of the items can be selected by pressing the corresponding switch with the pen-shaped pointer  3 , or pressing a character portion representing each of the items with the pen-shaped pointer  3 . If the MENU button  25  is pressed after one of the modes (A3)-(H3) is set, the currently set mode returns to the SETTING mode that is the previous mode to the current mode. Each of the modes will be hereinafter explained.  
         [0085]    (A3) Serial-Shot Setting Mode  
         [0086]    If the serial-shot setting mode in the display portion  4  is pressed by the pen-shaped pointer  3 , “1 Single-Shot Mode” and “2 Serial-Shot Mode” are displayed in the display portion  4 . If either of these is pressed by the pen-shaped pointer  3 , the single-shot mode or serial-shot mode is selected.  
         [0087]    (B3) Flash Setting Mode  
         [0088]    If the flash setting mode in the display portion  4  is pressed by the pen-shaped pointer  3 , “1 Auto”, “2 Inhibit Flash” “3 Forced Flash” are displayed in the display portion  4 . If any of these is pressed by the pen-shaped pointer  3 , the mode is switched to the selected one of “Auto”, “Inhibit Flash” and “Forced Flash”. “Auto” is a mode in which flash light is automatically generated depending upon the brightness of an object, and “Inhibit Flash” is a mode in which the flash light is inhibited from being generated irrespective of the brightness of the object, while “Forced Flash” is a mode in which the flash light is generated irrespective of the brightness of the object.  
         [0089]    (C3) Image Quality Setting Mode  
         [0090]    If the image quality setting mode in the display portion  4  is pressed by the pen-shaped pointer  3 , “1 High Resolution” and “2 Normal” are displayed in the display portion  4 . If either of these is pressed by the pen-shaped pointer  3 , the mode is switched to “High Resolution” or “Normal”. If the “High Resolution” is selected, the images are displayed at high resolution when one frame of image is reproduced over the entire area of the display portion  4  or when four or nine frames of images are reproduced at the same time.  
         [0091]    (D3) LCD Display Mode  
         [0092]    If the LCD display mode in the display portion  4  is pressed by the pen-shaped pointer  3 , “1 LCD Actuated by Half-pressing”, “2 LCD Actuated in RECORD Mode”, and “3 LCD Not Actuated in RECORD Mode” are displayed. If any of these is pressed by the pen-shaped pointer  3 , the selected mode is established. In the (A1) photographed image recording mode as described above, it was explained that the power supply for the display portion  4  is turned on by half pressing the release button  12 . This is in the case that “1 LCD Actuated by Half-pressing” is selected.  
         [0093]    (E3) Time Setting Mode  
         [0094]    If the time setting mode in the display portion  4  is pressed by the pen-shaped pointer  3 , panels of “0” to “9” and panels of “:” and “/” are displayed. The date and time in the electronic camera can be initialized (or set) by selecting appropriate one(s) from these panels by means of the pen-shaped pointer  3 .  
         [0095]    (F3) Information Display Mode  
         [0096]    If the information display mode in the display portion  4  is pressed by the pen-shaped pointer  3 , various kinds of information, such as a remaining amount of battery, number of pictures that have been taken, and date and time, can be displayed for a sight.  
         [0097]    (G3) Sound-recording Operation Setting Mode  
         [0098]    If the sound-recording operation setting mode in the display portion  4  is pressed by the pen-shaped pointer  3 , one mode can be selected from four kinds of modes as explained with respect to (C1) sound-recording mode.  
         [0099]    (1) Mode in which sound recording is started when the recording button  13  is pressed, and is stopped when the button is released.  
         [0100]    (2) Mode in which sound recording is started when the recording button  13  is pressed, and stopped when the recording button  13  is pressed again.  
         [0101]    (3) Mode in which sound recording is started when the recording button  13  is pressed for a moment, and is stopped when the button is pressed again for a moment, and the recording continues if the recording button  13  is kept pressed and is terminated when the button  13  is released.  
         [0102]    (4) Mode in which photographing is effected when the release button is pressed, and sound recording continues while the release button is being pressed.  
         [0103]    (H3) Volume Control Mode  
         [0104]    If the volume control mode in the display portion  4  is pressed by the pen-shaped pointer  3 , “1 Volume Large”, “2 Volume Middle”, “3 Volume Small” and “4 Mute” are displayed in the display portion  4 . Alternatively, a bar representing the volume of sound and a volume switch may be displayed, and the volume can be set from Mute (right) to Volume Large (left) by moving the position of the volume switch on the bar.  
         [0105]    In the third embodiment as described above, the electronic camera is provided with a wide variety of modes for photographing, reproduction of photographed images, and setting of various conditions, and the operation for setting these modes is effected by the combination of the pen input detecting portion with the display in the display portion and the specially positioned print sheet. This eliminates a need to provide additional switches, dials or the like for designating the modes, thus leading to improved operating efficiency, reduced cost of the camera, and reduced number of steps for manufacturing the camera.
