  If “year, month, day, and multiple days” is selected in step S1, the control unit 20 controls the recording unit 50 to search the interlocking information table 60 recorded in the memory card 51. Then, the shooting date / time of the latest shooting date / time and the reduced image data of the shooting date / time are extracted (step S11), and the process branches to the clock & image display processing subprogram to display the clock and reduction shown in FIG. Image display processing is performed to display the analog clock 81 and the reduced image 84 (step S12).

  Next, the interlocking information table 60 recorded in the memory card 51 is checked by controlling the recording unit 50. If there is no information regarding the image photographed on the selected day, the process proceeds to step S23 (step S13). If there is a photographed image of the selected date, the recording unit 50 is controlled to take out the next photographing date and time and reduced image data in the interlocking information table 60 recorded in the memory card 51 and return to step S12 (step S14). .

  If “year, month” is selected in step S1, the control unit 20 controls the recording unit 50 to search the interlocking information table 60 recorded on the memory card 51 and select the selected month. The most recent shooting date and time and the reduced image data of the shooting date and time are extracted (step S15), and the program branches to the clock & image display processing subprogram to perform the clock and reduced image display processing shown in FIG. A clock 81 and a reduced image 84 are displayed (step S16).

  Next, the recording unit 50 is controlled to check the interlocking information table 60 recorded on the memory card 51. If there is no information regarding the image photographed in the selected month, the process proceeds to step S23 (step S17). If there is a captured image in the designated time zone, the recording unit 50 is controlled to extract the next shooting date and time and reduced image data in the interlocking information table 60 recorded in the memory card 51, and the process returns to step S16 (step S18). ).

  When “only time zone” is selected in step S1, the control unit 20 controls the recording unit 50 to search the interlocking information table 60 recorded on the memory card 51, and shoots in the selected time zone. The shooting date and time and the reduced image data of the newest image among the recorded images are extracted (step S19), and the clock and the reduced image display processing shown in FIG. 81 and the reduced image 84 are displayed (step S20).

  Next, the recording unit 50 is controlled to check the interlocking information table 60 recorded on the memory card 51. If there is no information regarding the image taken in the selected time zone, the process proceeds to step S23 (step S21). When there is information about the image taken in the selected time zone, the recording unit 50 is controlled to display the next shooting date and time of the linked information table 60 recorded in the memory card 51 and the reduced image data of the shooting date and time. It takes out and returns to step S20 (step S22).

  Information related to the image taken in the time zone specified in the step S4, S8, S12, S16, or S20 when the display end operation is performed by the clock & image display processing subprogram of FIG. If not, the screen is cleared and the interlocking display operation is terminated (step S23).

  FIG. 8 is a flowchart showing an operation example of the clock & image display processing subprogram. When there is a transition from step S4, S8, S12, S16, or S20 in FIG. 7, the position of the clock hand 82 of the analog clock 81 (the needle tip) based on the shooting date and time acquired in any of these steps. Coordinate (x, y)) is determined, the clock hand 82 is displayed based on the determined position (step S4-1), and the reduced image data associated with the shooting date extracted in the above step is stored in the memory card. (Step S4-2), and the reduced image 84 is displayed based on the extracted reduced data (Step S4-3).

  Next, the control unit 20 checks whether or not a predetermined display time (for example, 5 seconds) has passed (step S4-4), and if the display time has passed, a step corresponding to the transition source step in FIG. The process returns to S5, S9, S13, S17, or S21, and if it has not elapsed, the process proceeds to step S4-5 (step S4-4).

  If the display time has not elapsed, the control unit 20 checks whether or not the cursor key 35 has been operated. If the cursor key 35 has not been operated to the right (>), the process proceeds to step S4-8 (step S4-5). When the operation is performed to the right, the period is advanced by the number of operations in units of the period (time zone, day, multiple days (eg, week), month) selected in step S1 or step S2 in FIG. Then, the linked information table 60 recorded in the memory card 51 is searched, and the shooting date and time and the reduced image data of the newest image among the images shot during the selected period are extracted (step S4-6) and acquired. The position of the clock hand 82 of the analog clock 81 is determined based on the shooting date and time, and the process proceeds to step S4-16 (step S4-7).

  If the cursor key 35 is not operated to the left (<), the process proceeds to step S4-11 (step S4-8). If the cursor key 35 is operated to the left, the period (time zone, day) selected in step S1 or step S2 of FIG. Searching the linked information table 60 recorded in the memory card 51 by going back the period by the number of operations in units of a plurality of days (for example, week) and month), and among the images taken in the selected period Then, the shooting date and time and the reduced image data of the newest image are extracted (step S4-9), the position of the clock hand 82 of the analog clock 81 is determined based on the acquired shooting date and time, and the process proceeds to step S4-16 (step S4). -10).

  When the position of the clock hand 82 of the analog clock 81 is not designated by the cursor key 35, the process proceeds to step S4-15 (step S4-11). When the position of the clock hand 82 is designated, the position of the designated position is changed. Time is obtained from the coordinate data (X, Y) (step S4-12), the interlocking information table 60 recorded in the memory card 51 is searched, and the shooting date and time of the image taken at the time closest to the obtained time and The reduced image data is extracted (step S4-13), the position of the clock hands 82 of the analog clock 81 is determined based on the acquired shooting date and time, and the process proceeds to step S4-16 (step S4-14).

  The control unit 20 checks whether a display end operation (for example, an up / down (∧∨) movement operation of the cursor key 35) has been performed. If the end operation has been performed, the process proceeds to step S23 in FIG. Returns to step S4-4 (step S4-15).

  The analog clock 81 with the clock hand 82 advanced (or retracted) at the position determined in steps S4-7, S4-10, and S4-14 is displayed (step S4-16), and the reduced size taken out from the memory card is displayed. A reduced image 84 is displayed based on the data (step 4-17).

  Next, the control unit 20 checks the signal from the operation unit 30 to check whether or not the DISP button 39 has been pressed. If the DISP button 39 has been pressed, the process proceeds to step S4-19; otherwise, the process proceeds to step S4. -4 (step S4-18).

  When the DISP button 39 is pressed, the control unit 20 searches the interlocking information table 60 recorded on the memory card 51 with the acquired shooting date and time, that is, image data of an image shot at the shooting date and time (that is, the image data). The original image data (compressed image data) of the reduced image 84 that is displayed is taken out (step S4-19), subjected to expansion processing, and sent to the display unit 40, as an image 85 as shown in FIG. 6C. Reproduction display is performed (step S4-20).

  The control unit 20 checks the signal from the operation unit 30 to check whether the DISP button 39 has been pressed again. If the DISP button 39 has been pressed, the control unit 20 returns to the linked display screen of the clock and the reduced image at step S4- 16 (step S21), if not, it is checked whether or not an end operation (for example, up / down (∧∨) movement operation of the cursor key 35) has been performed. If the end operation has been performed, the process proceeds to FIG. The process returns to step S5, S9, S13, S17, or S21 corresponding to the original step (step S4-22).

  According to the flowcharts of FIGS. 7 and 8, it is possible to view images taken within a selected period while sequentially feeding the images in chronological order. In other words, since the shooting time of the newest image taken during the specified period is displayed in analog clock format, it is easy to understand when the image was taken, and the user can see the scene and memories at the time of shooting. It becomes easier to recall. In addition, if the time is advanced or not retroactive with the cursor keys, the clock time advances along with the passage of time, and if there is an image taken at a certain clock time, the reduced image is displayed in conjunction with this. It is also possible to confirm that an image has been taken.

  In addition, by designating only the time zone, images taken at the same time (10 am on August 10th, 10 am on August 14th, ...) can be displayed sequentially on multiple days. It is also possible to perform time-series comparison of the regularly observed images.

  When displaying the analog clock 81 in steps S4-1 and S4-16 in FIG. 8 or displaying the reduced image 84 in steps S4-3 and S4-17, the shooting date may be displayed on the screen. desirable. In steps S4-3 and S4-17, it is desirable to display the reduced image relatively enlarged or reduced according to the display size (for example, the size of an analog clock) of another image on the screen. Further, in step S4-20, the reproduced image of the original image may be displayed in a relatively enlarged or reduced manner according to the display size of other images on the screen.

  In addition, if there are multiple images taken at the same time, one representative image (start or end) is displayed in conjunction with an analog clock, or a multi-screen display is displayed. Displayed, or sequentially switching display every predetermined time, selecting and displaying a display image at random, or changing the selected image according to the period (for example, the first image on the first day, the second image on the second day) 3rd day, 3rd, ...).

1-2: Clock and slide show linked display FIG. 9 is a schematic flowchart showing an example of clock and slide show linked display operation, and FIGS. 10 to 12 are diagrams showing examples of clock and slide show linked display, FIG. 10 shows an example of slideshow display of images taken in the same time zone as the current time regardless of the date, and FIG. 11 shows images of the latest reproduction date in a random order together with a clock indicating the shooting time. FIG. 12 shows an example of switching to a slide show type, FIG. 12 shows an example of images 105, 106,... Of the most recent reproduction date assigned at random to a screen together with a clock indicating a shooting time, and FIG. An example in which date images 105, 106,... Are stacked and displayed in a random order together with a clock indicating the photographing time. 10 to 13, reference numeral 101 denotes an analog clock, reference numeral 102 denotes a reproduced image displayed as a slide show, and reference numeral 103 denotes a shooting date. 10 to 13, reference numeral 104 indicates the current time. In this embodiment, it is assumed that the interlocking information table 60 (FIG. 4) has an image reproduction date storage column, and the reproduction date is overwritten and stored every time an image is reproduced.

  In FIG. 9, in the playback mode, the control unit 20 checks whether or not the user has selected the slide show display function. If the slide show display function is selected, the control unit 20 proceeds to step T2, otherwise proceeds to step T10 (step T1). ).

When the slide show display function is selected, the control unit 20 searches for the reproduction date / time of the interlocking information table 60 (FIG. 4), checks whether there is an image taken in the same time zone regardless of the date, and takes the photo in the same time zone. If there is a processed image, the process proceeds to step T3, and if not, the process proceeds to step T6 (step T2).
When there is a photographed image taken in the same time zone as the current time, the control unit 20 searches for the reproduction date and time in the interlocking information table 60 and regardless of the date, the same time zone as the current time (1 hour, 30 minutes, 15 10) (step T3), and the image data obtained by the search is reproduced at a predetermined time interval as shown in the examples of FIGS. 10 (a) to 10 (c). The playback image 102 is displayed (step T4), and the analog clock 101 indicating the current time, the shooting date 103, and the current time are displayed together with the playback image 102, and the process proceeds to step T8 (step T5).

  When there is no photographed image photographed in the same time zone as the current time, the control unit 20 retrieves the reproduction date and time of the linkage information table 60, extracts the image data of the photographed image at the most recently reproduced date and time, and FIG. As shown in any of the examples of FIG. 12 or FIG. 13, the reproduced image 102 is displayed by reproduction (step T6). The reproduced image 102 is displayed together with the analog clock 101 indicating the current time, the shooting date 103, and the current time. The display is superimposed and the process proceeds to step T8 (step T7).

  When a predetermined time elapses after the end operation by the user or all images within the time period are reproduced and displayed (step T8), the reproduction date and time on the interlocking information table 60 relating to the displayed image is updated with the current date and time, and the process is terminated. (Step T9).

  In the description of FIG. 9 to FIG. 13 described above, images taken in the same time zone (15 minutes, 30 minutes, 1 hour, etc.) as the current time are described. However, the time zone for the slide show display is the same as the current time. It is not limited to the time zone. For example, the time zone specified by the user or the same time zone as the shooting time of a certain image may be used. In this case, it is desirable that the analog clock displayed in conjunction with the display indicates the shooting time of the displayed image.

  With the above configuration, you can display the shooting time of an image that is displayed in an analog slide show with an analog clock along with the image, and slide the multiple images that were shot in the same time zone as the current time or the specified time. Can be displayed.

  In addition, when there is no photographed image taken at the same time zone as the current time, an image of the latest reproduction date is displayed in a slide-show manner in an at random order together with an analog clock indicating the photographing time (FIG. 11). ), The image of the most recent playback date is assigned and displayed on the screen at random together with the clock indicating the shooting time (FIG. 12), or the image of the latest playback date is displayed in random order with the clock indicating the shooting time. By displaying in a stacked manner (FIG. 13), it is possible to know a list of recently reproduced images.

(Embodiment 2)
In the present embodiment, an image captured within a period (time zone, day, week, or month) designated or selected in the calendar or a reduced image thereof is displayed in association with (= corresponding to) the clock time. Hereinafter, the digital camera 100 will be described as an example of the image display device with reference to FIGS. Note that the original image of the reduced image displayed in conjunction with the analog display clock (hereinafter referred to as “analog clock”) in the present embodiment is not limited to a still image, and may be a moving image.

2-1: Parallel Display of Captured Image and Calendar FIG. 14 is a diagram showing an example of an interlocking display screen of a display image and the calendar of the shooting date. Reference numeral 141 is a reproduced image, and reference numeral 142 is a reproduced image. The calendar of the month, symbol 143 indicates the shooting date and time. In this example, the shooting date is highlighted. FIG. 15 is a flowchart showing an example of a linked display operation of the display image and the calendar of the shooting date.

  In FIG. 15, when the user operates the mode dial 31 to select the playback mode, the control unit 20 controls the recording unit 50 to read the image data (compressed data) recorded on the memory card 51 and the image information. The read image data is reproduced and transferred to the DRAM 14 (step U1), and the read image data is reproduced and sent to the display unit 40 to be displayed on the liquid crystal monitor screen 41 as the reproduced image 141. At this time, the reproduced image 141 is relatively reduced and displayed in accordance with the display size of the calendar 142 (step U2).

  Further, the shooting date and time is taken out from the acquired image information, and the calendar data corresponding to the shooting date is acquired from the OSD data ROM 45, sent to the display unit 40, and arranged in the reproduced image 141 displayed on the liquid crystal monitor screen 41. The year / month calendar 142 is displayed (step U3).

  Further, a display control code is sent to the display unit 40 to discriminate display (inverted display in the example of FIG. 14) so as to be different from other dates in order to emphasize the date corresponding to the shooting date of the calendar 142 (step U4). .

  Next, the control unit 20 examines a signal from the operation unit 30 to determine whether or not the user has operated the cursor key 35 to the right (>). If the user has performed the right operation, the process proceeds to Step U6 and an end operation has been performed. In this case, the reproduction mode is terminated (step U5).

  When the right operation is performed in step U5, the next compressed image data stored in the memory card 51 is read out and transferred to the DRAM 14, and the process returns to step U2 (step U6).

  When the image is played back by the operation shown in the flowchart of FIG. 15 above, the calendar of the shooting date of the image is displayed in parallel and the shooting date is highlighted by reverse display, etc. Easy to remember scenes and events.

  It should be noted that (1) when a favorite reproduction image is designated by a cursor operation or the like, a discrimination display (for example, blinking the date) may be performed so that the favorite image is found. (2) When playing back the second and subsequent images, the shooting date of the image that has already been played back in the current playback mode operation is changed to a highlighted display method (for example, white) other than the reverse display and displayed. You may make it do. (3) When a date is selected on the calendar, an image reproduced on that day may be reproduced and displayed.

  By combining the above (1), (2), and (3), if you want to view the replayed image again, or if you want to transfer only the favorite image among the replayed images to the external image processing device, When you want to print, you can transfer or print your favorite image simply by specifying the date that is displayed in a discriminatory manner.

  Further, when there are a plurality of captured images on the same day, a mark indicating that (for example, ¬) may be displayed in the date column, or the number of images may be displayed near the date.

2-2: Display of Image on Calendar FIG. 16 is a diagram showing an example of image-linked display on the calendar.

A reduced image denoted by reference numeral 162 in FIG. 16 indicates a reduced image selected by the user by operating the cursor key 35. When the reduced image displayed in FIG. 16 is selected / designated by a cursor operation or the like, the original image 166 is displayed. When there are a plurality of images taken on the same day, display by the DISP button 39 is performed. After the switching operation or a predetermined time has elapsed, the next original image 167 is displayed.

  FIG. 17 is an example of a list display by the weekly calendar 170, and reduced data of captured images for seven days can be displayed for each week. In this example, a time frame is displayed below each day of the week and date, and a reduced image 171,. is there. When FIG. 17 is displayed, when the user presses the DISP button 39, the display is switched to FIG. When the DISP button 39 is further pressed, the display is switched to FIG. A reduced image indicated by reference numeral 172 in FIG. 17 indicates a reduced image selected by the user by operating the cursor key 35. When the reduced image 172 displayed in FIG. 17 is selected / designated by a cursor operation or the like, the original image 176 is displayed. When there are a plurality of images taken in the same time zone, the DISP button 39 is displayed. After the display switching operation or the predetermined time has elapsed, the next original image is displayed.

  FIG. 18 shows a clock-type daily calendar, and a reduced image within a 12-hour or 24-hour frame of the dial of the analog clock-like calendar 180 corresponding to the shooting time and time zone of the image taken on that day. Is an example in which is superimposed and displayed. When FIG. 18 is displayed, when the user presses the DISP button 39, the display is switched to FIG. When the DISP button 39 is further pressed, the display is switched to FIG. A reduced image indicated by reference numeral 182 in FIG. 18 indicates a reduced image selected by the user by operating the cursor key 35. When the reduced image 182 displayed in FIG. 18 is selected / designated by a cursor operation or the like, the original image 186 is displayed. When there are a plurality of images taken in the same time zone, the DISP button 39 is displayed. After the display switching operation or the predetermined time has elapsed, the next original image 187 is displayed.

  In addition, when there are a plurality of images taken on the same date (FIG. 16) or the same time zone (FIGS. 17 and 18) on the same date, a mark (in the example shown, ¬) 165 indicating that fact, 175 and 185 are displayed in the vicinity of the reduced image. At this time, the reduced image displayed on the date (or on the time zone) is a representative image among a plurality of images (in the embodiment, on the date or on the same time zone on that date). The first image is a reduced image (6th day, 10th day, 28th day in FIG. 16, 28th day in FIG. 17 from 6 to 9 o'clock, 12:00 to 3 pm, 30th from 12:00 to 4 pm, FIG. 1 to 3 o'clock, 4 o'clock to 5 o'clock, 9 o'clock to 11 o'clock, refer to the reduced image).

  When the cursor key 35 is operated to the left (<) or right (>), the number of months is advanced according to the number of operations in the example of FIG. 16, or the calendar and the month are photographed by going back the number of months according to the number of operations. A reduced image of the selected image is displayed on the date. In the example of FIG. 17, the week is advanced according to the number of operations, or the calendar and the reduced image of the image photographed in that week are traced back according to the number of operations. 18 is displayed on the date and time zone. In the example of FIG. 18, the number of days is advanced according to the number of operations, or the calendar and a reduced image of the image taken on that day are displayed on the time zone by going back the number of days according to the number of operations. Is done.

  FIG. 19 is a flowchart showing an example of an image linked display operation on the calendar. When the playback mode is selected by the digital camera 100 (step V1), the control unit 20 first reads the current month from the OSD data ROM 45. The calendar data is read, the monthly calendar of the current month is displayed, the signal from the operation unit 30 is checked, and if the DISP button 39 is pressed, the process proceeds to step V12, otherwise the cursor key 35 left (<), It is checked whether or not a right (>) operation has been performed, and the process proceeds to step V3 (step V2).

  According to the number of left / right operations of the cursor key checked in step V2, the monthly calendar data of the month that is advanced or retroactively read out from the OSD data ROM 45, and the monthly calendar of the corresponding month is displayed (step V3) and recorded. The image capturing time 61 in the interlocking information table 60 of the memory card 51 is searched by controlling the unit 50 (step V4). If there is reduced image data for the corresponding month, the process proceeds to step V6, and there is no reduced image data for the corresponding month. Advances to step V9 (step V5).

  If there is reduced image data for the corresponding month, the pointer 63 of the reduced image data for the corresponding month is obtained from the linkage information table 60, and the reduced image data photographed in the corresponding month is read, and the image of the displayed calendar date is displayed. A reduced image is displayed in the date column corresponding to the shooting date. If there are reduced image data of a plurality of images taken on that day, the reduced image of the first image is displayed (step V6). When the representative image is displayed, a display mark indicating that (in the example of FIG. 16, mark 165 (¬ mark)) is displayed (step V7).

  Next, it is checked whether or not the displayed image is the last image of the month, and if it is the last image, the process proceeds to step V9 assuming that the reduced image has been displayed on the calendar, and otherwise returns to step V4 ( Step V8).

  The user can select the date on which the reduced image is displayed by operating the cursor key 35 to the right (>) or left (<) and designate the date by pressing the SET key 351. Therefore, the control unit 20 checks the signal from the operation unit 30, and if the date selection / designation operation is not performed even after a predetermined time has passed, the process proceeds to step V11. If the date selection / designation operation is performed, Proceed to step V10 (step V9).

  Of the reduced images displayed in the date column of the monthly calendar, when the image indicating the representative image (that is, when there are a plurality of images taken on the same day) is designated, the user presses the cursor key 35. The page can be returned or sent by up (∧) / down (∨) operation. Therefore, the control unit 20 examines the signal from the operation unit 30 and, every time the cursor key 35 is operated under (∨), the reduced image data photographed on the same day is taken out from the memory card 51 in the normal order and designated on the specified date. Overwrite display. Further, every time the cursor key 35 is operated (∧), the reduced image data photographed on the same day is taken out from the memory card 51 in the reverse order and is overwritten and displayed on the designated date (step V10).

  When the user moves the cursor on a desired reduced image by operating the cursor key 35 and depresses the SET key 351, the selected image can be reproduced and displayed. Therefore, the control unit 20 examines the signal from the operation unit 30, and proceeds to step V32 if the SET key 351 is depressed, and returns to step V9 otherwise (step V11).

  When the DISP button 39 is pressed in step V2, the control unit 20 first reads the calendar data for the current week from the OSD data ROM 45, displays the weekly calendar for the current week, and then receives a signal from the operation unit 30. If the DISP button 39 is pressed, the process proceeds to step V22. If not, the process proceeds to step V13 after checking whether the left (<) and right (>) operations of the cursor key 35 have been performed (step S13). Step V12).

  The weekly calendar data for the week that is advanced or retroactively read out from the OSD data ROM 45 according to the number of left / right operations of the cursor key checked in step V12 is displayed (step V13) and recorded. The image capturing time 61 of the interlocking information table 60 of the memory card 51 is searched by controlling the unit 50 (step V14). If there is reduced image data for the corresponding week, the process proceeds to step V16, and there is no reduced image data for the corresponding week. Advances to step V19 (step V15).

  If there is reduced image data for the corresponding week, the pointer 63 of the reduced image data for the corresponding week is obtained from the linkage information table 60 to read out the reduced image data photographed in the corresponding week, and the image of the displayed calendar date is displayed. A reduced image is displayed in the date column corresponding to the shooting date. If there are reduced image data of a plurality of images taken on that day, the reduced image of the first image among them is displayed as a representative image (step V16). When a representative image is displayed, a display mark indicating that (in the example of FIG. 17, mark 175 (¬ mark)) is displayed (step V17).

  Next, it is checked whether or not the displayed image is the last image of the corresponding week. If it is the last image, the process proceeds to step V19 assuming that the reduced image has been displayed on the calendar. Otherwise, the process returns to step V14 ( Step V18).

  The control unit 20 examines the signal from the operation unit 30, and if the date selection / designation operation (left / right operation of the cursor key 35) is not performed even after a predetermined time has passed, the process proceeds to step V21, where the date selection / designation operation is performed. If it is performed, the process proceeds to Step V20 (Step V19).

  Of the reduced images displayed in the date column of the weekly calendar, when an image in which a representative image is displayed is designated, the user can return or send the page by a cursor operation. Therefore, the control unit 20 examines the signal from the operation unit 30 and, every time the cursor key 35 is operated under (∨), the reduced image data photographed on the same day is taken out from the memory card 51 in the normal order and designated on the specified date. Overwrite display. Further, every time the cursor key 35 is operated (∧), the reduced image data photographed on the same day is taken out from the memory card 51 in reverse order and overwritten on the designated date (step V20).

  When the user moves the cursor on a desired reduced image by operating the cursor key 35 and depresses the SET key 351, the selected image can be reproduced and displayed. Therefore, the control unit 20 examines the signal from the operation unit 30, and proceeds to step V32 if the SET key 351 is depressed, and returns to step V19 otherwise (step V21).

  When the DISP button 39 is pressed in step V12, the control unit 20 first reads the current day calendar data from the OSD data ROM 45, displays the current day daily calendar, and then from the operation unit 30. The signal is checked, and if the DISP button 39 is pressed, the process proceeds to step V2. If not, it is checked whether the left (<) and right (>) operations of the cursor key 35 have been performed, and then the process proceeds to step V23. (Step V22).

  The daily calendar data of the day advanced or retroactively read out from the OSD data ROM 45 according to the number of left / right operations of the cursor key checked in step V22 is displayed (step V23). The recording unit 50 is controlled to search for the shooting time 61 in the interlocking information table 60 of the memory card 51 (step V24). If there is reduced image data for the corresponding day, the process proceeds to step V26, and there is no reduced image data for the corresponding day. In this case, the process proceeds to Step V29 (Step V25).

  When there is reduced image data for the corresponding day, the pointer 63 of the reduced image data for the corresponding day is obtained from the linkage information table 60, the reduced image data photographed on that day is read, and the time or time zone column of the displayed calendar is displayed. The reduced image is displayed in the time or time zone column corresponding to the image shooting time. If there are reduced image data of a plurality of images taken at that time or time zone, the reduced image of the first image among them is displayed as a representative image (step V26). Further, when a representative image is displayed, a display mark to that effect (mark 185 (¬ mark) in the example of FIG. 18) is displayed (step V27).

  Next, it is checked whether or not the displayed image is the last image of the corresponding day, and if it is the last image, the process proceeds to step V29 on the assumption that the reduced image has been displayed on the calendar, and otherwise returns to step V24 ( Step V28).

  The control unit 20 examines the signal from the operation unit 30, and if a time or time zone selection / designation operation (left / right operation of the cursor key 35) is not performed even after a predetermined time has passed, the process proceeds to step V31, where the time or time If a band selection / designation operation is performed, the process proceeds to step V30 (step V29).

  When an image on which a representative image is displayed is specified among the reduced images displayed in the time or time zone column of the daily calendar, the user can return or send the page by operating the cursor. . Therefore, the control unit 20 examines the signal from the operation unit 30 and, every time the cursor key 35 is operated under (∨), the reduced image data photographed on the same day is taken out from the memory card 51 in the normal order and designated on the specified date. Overwrite display. Further, every time the cursor key 35 is operated (∧), the reduced image data taken on the same day is taken out from the memory card 51 in the reverse order and overwritten on the designated date (step V30).

  When the user moves the cursor on a desired reduced image by operating the cursor key 35 and depresses the SET key 351, the selected image can be reproduced and displayed. Therefore, the control unit 20 examines the signal from the operation unit 30, and proceeds to step V32 if the SET key 351 is depressed, and returns to step V29 otherwise (step V31).

  The control unit 20 takes out the pointer of the original image corresponding to the reduced image selected in step V11, V21, or V31 from the linkage information table 60, and controls the recording unit 50 to take out the image data of the original image and reproduce it. Processing is performed and a reproduced image is displayed (step V32).

  16 to 18 and FIG. 19, the reduced images are displayed in the date column of the monthly calendar and weekly calendar corresponding to the shooting date and time or the time zone column of the daily calendar, and the same day or Even when there are a plurality of images taken in the same time zone, it is possible to search the image easily because it is possible to select the image by turning the page, or to select the images by sorting them by time or time zone on the daily calendar.

  Note that, in steps V6, V16, V26, V10, V20, and V30 in the flowchart of FIG. 19, the reduced image is relatively matched with the display size of other images on the screen (for example, the size of the date field). It is desirable to enlarge or reduce the display. Further, in step V32, the reproduced image of the original image may be displayed in a relatively enlarged or reduced manner according to the display size of other images on the screen.

  20 to 22 are diagrams showing another embodiment of image-linked display on the daily calendar. FIG. 20 shows the daily calendar 201 (FIG. 20A) displaying 12 hours in the daytime and 12 hours in the nighttime. This is an example in which the displayed daily calendar 202 (FIG. 20B) can be switched and displayed, and when switching to the daily calendar is displayed at step V22 in the flowchart of FIG. 19, it is automatically determined whether it is daytime or nighttime from the current time. When the judgment is made so that the daily calendar 201 or the daily calendar 202 is displayed or the DISP button 39 is pressed in any step after step V23, the display switching between the daily calendar 201 and the daily calendar 202 is performed. It may be configured to do.

  FIG. 21 shows an example of a daily calendar that allows a list display of images taken on that day in a 24-hour system. FIG. 22 shows an example of a daily calendar in which images shoot on a certain day are arranged in a bar graph or in a straight line with time 223 and time zone and a list of reduced images 222 is displayed there. Data related to timekeeping information such as a calendar, a monthly example, six days of the week, or the contents 224 of an individual or work schedule (schedule) may be displayed together. For example, as shown in the daily calendar 220 of FIG. 22, when the reduced image 222 and the scheduled content data 224 of the captured image of the day are displayed in order of time, the past events of the day are stored as if reading a diary. It is convenient because it can be revived.

  FIG. 23 is a diagram showing an example of the reproduction and display of an image taken in a designated time zone regardless of the calendar date. FIG. 23A shows the time zone 231 on the vertical axis and the date 232 on the vertical axis. This is an image list calendar on the horizontal axis, and a reduced image 233 of the corresponding photographed image is superimposed and displayed by date and time zone. Further, when there are a plurality of images taken in the same time zone, a mark (in the illustrated example, ¬) 234 is displayed together with the reduced image. FIGS. 23B to 23E show examples of reproduction display of images taken in a specific time zone (in this example, from 6 o'clock to 7 o'clock). FIG. 24 is a flowchart showing a reproduction display example of an image taken in a designated time zone.

  24, in the playback mode, the control unit 20 displays the image list calendar 230 as shown in FIG. 23A, prompts the user to select a time zone (step W1), and the user selects the image list calendar 230. When the time zone is specified (step W2), the control unit 20 searches for the shooting date / time 61 in the interlocking information table 60 (FIG. 4) and checks whether there is an image shot in the same time zone regardless of the date. (Step W3) If there is an image taken in the same time zone, the image pointer is taken out, the image data in the designated time zone is sequentially taken out from the memory card 51, and reproduction processing is performed (Step W4). Images are sequentially displayed (step W5).

  With the operation shown in the flowchart of FIG. 24, for example, “search by time” that searches only images at dawn, sunset or night can be performed, so when there are a large number of images or shooting dates cannot be remembered. Even in this case, it is possible to quickly search for the same kind of image.

<Modification 1>
Various information other than those described above may be displayed on the calendars displayed in FIGS. 10 to 14 and FIGS. 16 to 23. Hereinafter, FIG. 25 shows an example of information display on a calendar in which images are displayed in conjunction with each other.

  25A shows the number of images taken on the date (or time zone) of the calendar date in the date column (or time zone column) together with the reduced image (FIG. 25 (a-1)). This is an example in which the presence or absence of recording or moving images is displayed with marks or the like (FIG. 25 (a-3)). In this case, information such as the number of shots may be displayed in a discriminative manner by blinking or the like in order to clearly distinguish it from the date. Note that information such as the number of shots may be overwritten on the reduced image displayed in the date column (or time zone column).

  Information display such as the number of shots may be turned on / off by pressing the DISP button 39. Further, on / off may be switched every n seconds without pressing the DISP button 39. If there are a plurality of images taken on the same day (or the same time zone), the second, third,... Image is reproduced and displayed in the date column when the DISP button 39 is pressed. You may make it do.

  FIG. 25B is an example in which the notification information is changed each time the DISP button 39 is pressed, FIG. 25B-1 is an example in which the date is displayed, and FIG. 25B-2 is the number of shots. FIG. 25B-3 shows an example in which the presence or absence of a recording or a moving image is displayed. Note that the notification information may be switched without pressing the DISP button 39.

  FIG. 25C shows an example in which an information display area is provided at a specific position on the calendar and information relating to the selected image is displayed there. FIG. 25D shows an example in which when the DISP button 39 is pressed, the information of the selected image is displayed in a balloon in association with the date field or the displayed reduced image, and the displayed information is easy to read. In FIG. 25 (e), when the DISP button 39 is pressed, the information of the enlarged image is displayed, and not only the page display such as the number of the image but also the information such as the image size and image quality is displayed. It is an example.

<Modification 2>
FIG. 26 and FIG. 27 are diagrams showing an example of image-linked display on a calendar with a bar graph, in which the shooting time is displayed as a graph. FIG. 26 (a) shows a 24-hour display. FIG. 26B shows a reproduction image 265 of the selected image displayed in conjunction with the calendar 260 with a bar graph, and FIG. 27A shows a calendar 270 with a bar graph displayed for one hour. FIG. 27B shows an example of a reduced image that is linked and displayed, and FIG. 27B shows a reproduced image 275 of the selected image.

  In FIG. 26A, a 24-hour display bar graph 261 representing the shooting time is displayed on the outer periphery of the calendar 260, and a reduced image 262- of the image shot in the calendar month (July 2003 in this example). 1, 262-2, 262-3, and 262-4 are displayed in the date column corresponding to the shooting date. In the example shown in the figure, the reduced image displayed in the display column is a representative image of a still image or a moving image taken on the date of this date. Note that the display color of the frame may be changed between a still image and a moving image.

  Here, the photographing time display portions 261-1, 261-2, 261-3, and 261-4 indicated by diagonal lines in the bar graph 261 are reduced images 262-1 and 262 indicated in the selected date column. -2, 262-3, and 262-4, which indicate the shooting time of the still image or moving image (for example, the portion 261-2 of the bar graph 261 indicates the shooting time of the moving image shot on July 17, 2003) (Shows 10:00 to 11:40)), and the flashing interval is different between a still image and a moving image. Note that the display color of the frame may be changed between a still image and a moving image.

  For example, when a reduced image of the date field “20th” of the calendar 260 is selected by operating the cursor key 35 or the like, the selected date field blinks (or the display color changes) as shown in the figure, and at the same time, the calendar is displayed. The shooting time display portion 261-3 of the bar graph 261 on the outer periphery of 260 blinks (or the display color changes).

  In addition, by designating the shooting time display portion of the bar graph 261 on which the reduced image is displayed, the original image 265 can be reproduced and displayed as shown in FIG. The illustrated example is a display example of an image taken between 12:50 and 13:30 on July 20, 2003. When there are a plurality of still images taken in the same time zone, page up and page down can be performed by operating the cursor key 35 up and down. In addition, when a moving image is shot, the moving image display can be advanced or returned by the up / down operation of the cursor key 35.

  Further, when the DISP button 39 is pressed while the calendar 260 is displayed in FIG. 26A, the display is switched, and another time-displayed calendar display with a graph (for example, the calendar 270 in FIG. 27A) is displayed. Display).

  In FIG. 27A, a time 273 is displayed above the day of the week display field of the calendar 270, and a bar graph 271 displaying a one-hour display indicating the shooting time in minutes is displayed on the outer periphery of the calendar 270. In the date field of the calendar 270, among the images captured in the calendar month (in this example, July 2003), the reduced images 272-1, 272-2, and 272 captured on the day corresponding to the date field. -3, 272-4 are displayed. In the example shown in the figure, the reduced image displayed in the display column is a representative image of a still image or a moving image taken on the date of this date. Note that the display color of the frame may be changed between a still image and a moving image.

  Here, the photographing time display portions 271-1, 271-2, 271-3, and 271-4 indicated by diagonal lines in the bar graph 271 are the reduced images 272-1 and 272 indicated in the selected date column. -2, 272-3, and 272-4 are the original images of still images or moving images, and the flashing intervals are different between the still images and the moving images. Note that the display color of the frame may be changed between a still image and a moving image.

  Also, by specifying the shooting time display portion of the bar graph 271 on which the reduced image is displayed, the original image 275 can be reproduced and displayed as shown in FIG. The illustrated example is a display example of an image taken at 13:15 on July 20, 2003. When there are a plurality of still images taken in the same time zone, page up and page down can be performed by operating the cursor key 35 up and down. In addition, when a moving image is shot, the moving image display can be advanced or returned by the up / down operation of the cursor key 35.

  Further, when the DISP button 39 is pressed while the calendar 270 is displayed in FIG. 27A, the display is switched, and another time-displayed calendar display with a graph (for example, the calendar 260 of FIG. 26A) is displayed. Display).

  FIG. 28 is a flowchart showing a schematic operation example of the image interlocking display on the calendar with the bar graph display. When the reproduction mode is selected (step X1), the control unit 20 displays the designated year and month for 24 hours. A monthly calendar with a bar graph is displayed (step X2).

  Next, a reduced image photographed in the year and month indicated by the calendar is taken out from the memory card 51 and displayed in the date column of the monthly calendar with a bar graph corresponding to the photographing date as shown in the example of FIG. . If a plurality of images are taken on the same day, a representative image is displayed (step X3). Also, the color scheme of the time or time zone corresponding to the shooting time of the original image of the reduced image taken out of the 24-hour bar graph displayed on the outer periphery of the calendar is changed from the surroundings and displayed ( Step X4).

  The control unit 20 repeats steps X3 and X4 (step X5) until reduced images of all images taken in the month and month indicated on the calendar are displayed in the date column (step X5), and reduced images of all images are displayed in the date column. When it is displayed, it is checked whether or not the DISP button 39 has been pressed within a predetermined time. If the DISP button 39 has been pressed, the process proceeds to Step X7, and if not, the process proceeds to Step X12 (Step X6).

  When the DISP button 39 is pressed, the control unit 20 clears the screen and then displays a monthly calendar with a one-hour display bar graph of the specified year and month (step X7). A reduced image photographed in the year and month indicated by the calendar is taken out from the memory card 51 and displayed in the date column of the monthly calendar with a one-hour display bar graph corresponding to the photographing date as shown in the example of FIG. . When a plurality of images are taken on the same day, a representative image is displayed (step X8). In addition, the color scheme of the time or time zone corresponding to the shooting time of the original image of the reduced image extracted from the bar graph displayed for 1 hour displayed on the outer periphery of the calendar is changed from the surroundings (displayed). Step X9).

  The control unit 20 repeats the above steps X8 and X9 (step X10) until the reduced images of all the images taken in the month and month indicated on the calendar are displayed in the date column (step X10), and the reduced images of all the images are displayed in the date column. When it is displayed, it is checked whether or not the DISP button 39 has been pressed within a predetermined time. If the DISP button 39 has been pressed, the process returns to Step X2, and if not, the process proceeds to Step X12 (Step X11).

  If the DISP button 39 has not been pressed, it is checked whether or not the date field in which the reduced image is displayed has been designated by operating the cursor key 35 (step X12). If it is a moving image, the process proceeds to step X19 (step X13).

  If the specified image is a still image, the original image data of the reduced image (or the reduced image of the representative image) displayed in the specified date column is read from the memory card 51, and is reproduced by performing a reproduction process. The image is displayed (step X14), and it is checked whether or not the original image of the reduced image is a representative image (step X15). In the case of the representative image, the control unit 20 performs a page turning operation based on a signal from the operation unit 30. If a page turning operation is performed, that is, if there is a downward (∨) operation of the cursor key 35, the process proceeds to Step X17, and if not, the process proceeds to X18 (Step X16).

  When there is a page turning operation, the image data of the same shooting date is sequentially read out from the memory card 51 and subjected to playback processing to display a playback image (step X17). If a predetermined time has elapsed, the displayed calendar or The reproduced image is cleared and the process is terminated (step X18).

  The original image data (moving image data) of the reduced image displayed in the designated date column is sequentially read from the memory card 51, temporarily stored (held) in the DRAM 14 (step X19), subjected to reproduction processing and displayed (step S19). X20), it is checked whether or not the page turning / returning operation has been performed based on the signal from the operation unit 30, and when the page turning / returning operation has been performed, that is, the cursor key 35 is operated downward (∨) or upward (∧ ) If there is an operation, the process proceeds to step X22, and if not, the process proceeds to X23 (step X21).

  When there is a page turning / returning operation, the moving image data ahead or after the currently displayed moving image by the operation time is read out from the DRAM 14 in the normal or reverse order, subjected to reproduction processing and displayed (step X22). The control unit 20 also checks whether or not a moving image display end operation has been performed based on a signal from the operation unit 30, and if a moving image display end operation has been performed, clears the displayed calendar or playback image. The process ends, and if not, the process returns to Step X21 (Step X23).

  26 and 27, and the operation shown in the flowchart of FIG. 28, the shooting time is displayed in a graph around the calendar to be displayed, so that it can be seen at a glance how many images exist at which time on a specified date. Also, when playing back a moving image, you can see at a glance how long this cut (shooting unit) lasts.

  Also, because the graph is provided around the calendar, it does not take up space. Therefore, it is easy to see the calendar even in an image display device with a small screen, such as a digital camera, a mobile phone, or a cradle with a display unit whose screen size is limited. Furthermore, it is easy to specify a time on the bar graph and recall (= reproduce and display) an image taken at that time, and this is particularly effective for a moving image with a long shooting time.

  Note that it is desirable to display the reduced image relatively enlarged or reduced in accordance with the display size of other images on the screen (for example, the size of the date field) in steps X3 and X8 in FIG. Furthermore, in step X14 and X17, the reproduced image of the original image may be displayed while being relatively enlarged or reduced in accordance with the display size of other images on the screen.

  In the above embodiment, the graph display of time has been described by taking a bar graph as an example, but the graph display method is not limited to the bar graph. For example, a pie chart may be used. Moreover, although the graph of the calendar with a graph display is based on the 24-hour system and the 1-hour system, the present invention is not limited to these, for example, a 12-hour system or another time system may be used. In the above embodiment, the calendar period is set to one month. However, the calendar period is not limited to one month. For example, a unit of 10 days, a unit of week, or a unit of day may be used.

  Further, when the display screen is sufficiently wide like a personal computer (hereinafter referred to as a personal computer), the original images shown in FIGS. 26B and 27B may be displayed simultaneously for one month. In this way, a time graph is displayed on all days of a month, and can be grasped at a time.

  In the first embodiment and the second embodiment, the digital camera has been described as an example of the image display device, but the term image display device is not limited to the digital camera. For example, the present invention can also be applied to an electronic camera or an imaging device including a display unit, a mobile phone, a portable information terminal, a personal computer, a communication terminal including an image storage unit and a display unit, a cradle including an image display unit, and the like.
