With this setting, when the acceleration sensor 9 detects that the main body of the digital camera 21 is shaken, the operation accepting unit accepts an operation of a user who selects an image. Next, the control unit 8 sets the size of the constituent images of the thumbnail list image to a default value (S13). This default value corresponds to an NTSC analog television. Next, the control unit 8 displays a thumbnail display confirmation screen on the external monitor 18 (S14), and confirms with the user of the digital camera 21 whether or not to display the thumbnail list image on the external monitor 18. By this confirmation, it is determined whether or not the thumbnail list image is displayed on the external monitor 18 (S15). When this determination is “NO”, a standby state in which the process of S15 is repeated is entered. On the other hand, if this determination is “YES”, the control unit 8 causes the user of the digital camera 21 to perform settings for associating the selected images in the thumbnail list images displayed on the built-in monitor 16 and the external monitor 18 ( S16). Even in this setting, the type of relevance of the selected image in each thumbnail list image displayed on the built-in monitor 16 and the external monitor 18 from the menu screen of the digital camera 21 is selected from the three types of association settings 1 to 3 described above. Let them choose one. Next, the control unit 8 displays each thumbnail list image on the external monitor 18 of the television 31 and the built-in monitor 16 of the digital camera 21 with the association selected in the process of S16 (S17).

  FIG. 7 is a detailed flowchart of the thumbnail display process shown in S10 of FIG. 5 or S17 of FIG. 6 when association setting 1 is selected in S9 of FIG. 5 or S16 of FIG.

  First, the control unit 8 determines whether or not the thumbnail display mode is ended (see S21 in FIG. 7). If the determination in S21 is “YES”, the thumbnail display process ends. On the other hand, when the determination in S21 is “NO”, the control unit 8 determines whether or not there is an instruction to select the next image by the operation reception unit (S22). If this determination is “NO” and the user does not select the next image selected from the thumbnail list images, the process enters a standby state in which the process of S22 is repeated. On the other hand, when the process of S22 is “YES”, that is, when the operation receiving unit receives an operation for selecting the next image after the currently selected image on each monitor 16, 18, the control unit 8 receives each monitor. For the built-in monitor 16 in which the first image of each thumbnail list image displayed on 16 and 18 disappears, the display positions of the second and subsequent images are sequentially advanced, and a new image is displayed at the end of each thumbnail list image. Thumbnail list images for the external monitor 18 and thumbnail list images for the external monitor 18 are generated by the built-in monitor list image generating means and the external monitor list image generating means (S23).

  In this process, for example, in the case where an image of number 2 that is the next image of the currently selected first image in FIG. 3 or 4 is selected, the first image of number 1 is selected on the built-in monitor 16. Is deleted, and the display positions of the images with numbers 2 to 9 are sequentially incremented, and the image with the number 2 is set as the top image. Then, a new image of number 10 is entered at the end position where the number is 9, and nine images of numbers 2 to 10 are displayed. In the external monitor 18, the first image with the number 1 is deleted, the display positions of the images with the numbers 2 to 36 are sequentially advanced, and the image with the number 2 is set as the first image. Then, an image of number 37 is newly inserted at the rearmost position where the number is 36, and 36 images of numbers 2 to 37 are displayed. At this time, the selected images of the thumbnail list images on the built-in monitor 16 and the external monitor 18 are always at the same position (in FIG. 3 and FIG. 4, the position of the top left image of each thumbnail list image) and do not move. Thereafter, the process returns to the process of S21 and the above-described process is repeated.

  In the above description, the position of the cursor frame 41 is not limited to the first image position of number 1, but may be another image position (for example, an image position in the middle of numbers 2 and 3). In this case, as described above, since the selected images of the thumbnail list images are always at the same position, it is possible to identify the currently selected image on each of the monitors 16 and 18 without the cursor frame 41. Can do.

  FIG. 8 is a detailed flowchart of the thumbnail display processing shown in S10 of FIG. 5 or S17 of FIG. 6 when the association setting 2 is selected in S9 of FIG. 5 or S16 of FIG.

  First, the control unit 8 determines whether or not the thumbnail display mode is ended (see S31 in FIG. 8). If the determination in S31 is “YES”, the thumbnail display process ends. On the other hand, when the determination in S31 is “NO”, the control unit 8 determines whether or not there is an instruction to select the next image by the operation reception unit (S32). If this determination is “NO” and the user does not select the next image selected from the thumbnail list images, the process enters a standby state in which the process of S32 is repeated. On the other hand, when the process of S32 is “YES”, that is, when the operation accepting unit accepts an operation for selecting the next image after the currently selected image on each of the monitors 16, 18, the control unit 8 performs the operation. Is determined to be an instruction to select the next image after the last image of the thumbnail list image of the built-in monitor 16 (for example, the image of the number 9 at the lower right in FIG. 3) (S33).

  When the determination in S33 is “NO”, the control unit 8 determines that the selected image displayed in the first display mode is the next to the monitor 16 and 18 from the image currently displayed in the first display mode. Internal monitor list image generation for thumbnail list image for built-in monitor 16 and thumbnail list image for external monitor 18 other than the next image switched to the non-selected image displayed in the second display mode. And the list image generating means for external monitor, and the position of each selected image in the thumbnail list image of each monitor 16, 18 is moved by one frame (S34). In this process, for example, in FIG. 3, when the currently selected image is an image other than the last number 9 (for example, an image of number 5) in the built-in monitor 16, each of the built-in monitor 16 and the external monitor 18 The position of the selected image is moved, and the next image (for example, the image of number 6) is set as the selected image.

  On the other hand, if the process of S33 is “YES”, that is, the operation received by the operation receiving unit is an instruction to select the next image from the image of the last number 9 of the thumbnail list image displayed on the built-in monitor 16. If it is, the control unit 8 updates all the thumbnail list images of the built-in monitor 16 and updates the thumbnail list image of the external monitor 18 for nine frames (S35). That is, the control unit 8 deletes all the images having the number 1 to 9 constituting the thumbnail list image displayed on the built-in monitor 16 and deletes all the images from the next new image group having the number 10 to 18, for example. The thumbnail list image for the built-in monitor 16 is generated by the built-in monitor list image generation means 8. At the same time, the control unit 8 includes, for example, images numbered 1 to 36 constituting the thumbnail list image displayed on the external monitor 18 as nine frames corresponding to the total number of thumbnail list images displayed on the built-in monitor 16. Each display position of, for example, the numbered 10 to 36 images that have been erased and left off is sequentially advanced by 9 frames, and has been erased from the next display position of the last image that has been advanced, for example, the numbered 36 image. The external monitor list image generation means 8 is caused to generate a thumbnail list image for the external monitor 18 in which a new image group of, for example, numbers 37 to 45 for nine frames is displayed.

  Next, the control unit 8 returns the selected images displayed on the built-in monitor 16 and the external monitor 18 to the top positions of the thumbnail list images displayed on the built-in monitor 16 and the external monitor 18 (S36). As a result of this processing, the selected image displayed in the first display mode is switched from the last image, for example, number 9 in the thumbnail list image to the first image, for example, number 10 in the built-in monitor image 16. Then, for example, the image having the number 9 is switched to the head image having the number 10, for example. In addition, the non-selected images displayed in the second display mode are images other than the top image, for example, the numbers 11 to 18 on the built-in monitor 16, and images other than the top image, for example, the numbers 11 to 45, other than the top image. Switch. Thereafter, the process returns to the process of S31 again after the process of S34 or S36 described above, and the above process is repeated.

  FIG. 9 is a detailed flowchart of the thumbnail display process shown in S10 of FIG. 5 or S17 of FIG. 6 when the association setting 3 is selected in S9 of FIG. 5 or S16 of FIG.

  First, the control unit 8 determines whether or not the thumbnail display mode is ended (see S41 in FIG. 9). If the process of S41 is “YES”, the thumbnail display mode ends. On the other hand, when the determination in S41 is “NO”, the control unit 8 determines whether or not there is an instruction to select the next image by the operation receiving unit (S42). If this determination is “NO” and the user does not select the next image selected from the thumbnail list images, the process enters a standby state in which the process of S42 is repeated. On the other hand, when the process of S42 is “YES”, that is, when the operation receiving unit receives an operation for selecting the next image after the currently selected image on each monitor 16, 18, the control unit 8 performs the operation. Is determined to be an instruction to select the next image after the last image of the thumbnail list image of the built-in monitor 16 (for example, the image of the number 9 at the lower right in FIG. 3) (S43).

  When the determination in S43 is “NO”, the control unit 8 causes the built-in monitor 16 to change the selected image displayed in the first display mode from the image currently displayed in the first display mode to the next image. The thumbnail list image for the built-in monitor 16 that is changed to a non-selected image displayed in the second display mode other than the next image is generated by the built-in monitor list image generating means, and the thumbnail list of the built-in monitor 16 is displayed. The position of the selected image in the image is moved by one frame (S44). In this process, for example, in FIG. 3, when the selected image is an image other than the last number 9 on the built-in monitor 16 (for example, an image of number 5), the position of the selected image on the built-in monitor 16 is moved. Then, the next image (for example, the image of number 6) is set as the selected image.

  On the other hand, if the determination in S43 is “YES”, that is, the operation accepted by the operation accepting means is an instruction to select the next image from the image with the number 9 at the end of the thumbnail list image displayed on the built-in monitor 16. If it is, the control unit 8 updates all thumbnail list images of the built-in monitor 16 (S45). That is, the control unit 8 deletes all the images having the number 1 to 9 constituting the thumbnail list image displayed on the built-in monitor 16 and deletes all the images from the next new image group having the number 10 to 18, for example. The thumbnail list image for the built-in monitor 16 is generated by the built-in monitor list image generating means. Next, the selected image displayed on the built-in monitor 16 is returned to the top position of the thumbnail list image displayed on the built-in monitor 16 (S46). As a result of this processing, the selected image displayed in the first display mode on the built-in monitor 16 is switched from the rearmost image, for example, number 9 of the thumbnail list image, to the first image, for example, number 10, and the second image is displayed. The non-selected images displayed in the display mode are switched to images other than the first image, for example, numbers 11 to 18.

  Next, the control unit 8 selects the next image of the currently selected image received in S42 as the last image of the thumbnail list image of the external monitor 18 (for example, the number on the lower right in FIG. 4). It is determined whether or not it is an instruction to select the next image (36 images) (S47).

  When the determination in S47 is “NO”, the control unit 8 causes the external monitor 18 to change the selected image displayed in the first display mode from the image currently displayed in the first display mode to the next image. The external monitor list image generating means generates thumbnail list images for the external monitor 18 other than the next image that is switched and the non-selected image displayed in the second display mode is switched, and the thumbnail list of the external monitor 18 is displayed. The position of the selected image in the image is moved by one frame (S48). In this process, for example, in FIG. 4, when the currently selected image is an image other than the last end number 36 on the external monitor 18 (for example, the image of number 15), the position of the selected image on the external monitor 18 is determined. The next image (for example, image number 16) is selected as the selected image.

  On the other hand, if the determination in S47 is “YES”, that is, the operation accepted by the operation accepting means is an instruction to select the next image from the number 36 at the end of the thumbnail list image displayed on the external monitor 18. If it is, the control unit 8 updates all thumbnail list images of the external monitor 18 (S49). That is, the control unit 8 deletes all the images, for example, numbers 1 to 36 constituting the thumbnail list image displayed on the external monitor 18, and sets all the images to the next new image group, for example, the numbers 37 to 72. The thumbnail list image for the external monitor 18 is generated by the external monitor list image generation means. Next, the selected image displayed on the external monitor 18 is returned to the top position of the thumbnail list image displayed on the external monitor 18 (S50). As a result of this processing, the selected image displayed in the first display mode on the external monitor 18 is switched from the last image, for example, number 36 of the thumbnail list image, to the first image, for example, number 37. In addition, the non-selected image displayed in the second display mode is switched to an image of, for example, numbers 38 to 72 other than the top image. After the process of S48 or S50 described above, the process returns to the process of S41 again and the above process is repeated.

  It should be noted that the thumbnail list image displayed on the external monitor 18 is consistent with the movement of the thumbnail list images displayed on the external monitor 18 and the built-in monitor 16 as described above with reference to FIGS. The number is preferably an integral multiple of the number of thumbnail list images displayed on the built-in monitor 16. In the present embodiment, as shown in FIGS. 3 and 4, the number 36 of thumbnail list images displayed on the external monitor 18 is an integer of the number 9 of thumbnail list images displayed on the built-in monitor 16. It is 4 times that is double.

  According to the digital camera 21 according to the present embodiment as described above, when the user operates an image while viewing both thumbnail list images displayed on the built-in monitor 16 and the external monitor 18, the operation is performed by the operation reception unit. Since the image in the thumbnail list image displayed on the built-in monitor 16 and the image in the thumbnail list image displayed on the external monitor 18 are recognized as being the same by the association means, It becomes easier to grasp the correspondence between the thumbnail list images displayed on the monitor 16 and the external monitor 18 and the correspondence between the selected images selected in the thumbnail images, so that the screens of the built-in monitor 16 and the external monitor 18 can be operated simultaneously. Becomes easy.

  Further, according to the digital camera 21 according to the present embodiment, when the association setting 1 described with reference to FIG. 7 is set, an operation for selecting the next image of the currently selected image on each of the monitors 16 and 18. Is received by the operation accepting means, the display position of each selected image in the thumbnail list image with respect to each monitor 16, 18 does not move, and each selected image is fixed at a fixed display position on the screen of each monitor 16, 18. Has been. Therefore, when the user operates while viewing both the built-in monitor 16 and the external monitor 18, the display position of the selected image in each thumbnail list image can be easily grasped, and the thumbnail list of the built-in monitor 16 and the external monitor 18. It becomes easy to grasp the correspondence between images, and the screen operations of the monitors 16 and 18 are facilitated.

  Further, according to the digital camera 21 according to the present embodiment, when the association setting 2 described with reference to FIG. 8 is set, the selected image in the thumbnail list image displayed on the built-in monitor 16 is the last of the thumbnail list image. When an operation for switching from the end image to the next image is received by the operation receiving means, each thumbnail list image displayed on the built-in monitor 16 and the external monitor 18 is the total number of thumbnail list images displayed on the built-in monitor 16. Since the minutes are switched simultaneously, the correlation between the built-in monitor 16 and the external monitor 18 is easy to understand, and the simultaneous operation of the built-in monitor 16 and the external monitor 18 is facilitated. In addition, since the thumbnail list images of the monitors 16 and 18 are switched based on the built-in monitor 16, when the user operates the screen of the external monitor 18 based on the built-in monitor 16, the operation can be performed more easily. Become. Further, when the selected image displayed in the first display mode is switched from the currently displayed image to the next image, the display position of each selected image displayed in the first display mode in each thumbnail list image is Since one frame is moved and the previously selected image continues to be displayed, if it is desired to return to the previously selected image, it is possible to easily return while viewing each monitor 16 and 18 and display the previously selected image. It is possible and convenient. Further, since the same thumbnail list image is continuously displayed on each monitor 16 and 18 until the position of the selected image is moved by the number of all thumbnail list images displayed on the built-in monitor 16, the entire thumbnail list image is displayed. It becomes easy to grasp the positional relationship between the selected images.

  Further, according to the digital camera 21 according to the present embodiment, when the association setting 3 described with reference to FIG. 9 is set, the thumbnail list image displayed on the external monitor 18 is the thumbnail displayed on the built-in monitor 16. Since the number of updates to the next thumbnail list image is larger than the number of list images and the number of times the built-in monitor 16 is updated, the thumbnail list image is complicated for the user who operates while viewing the external monitor 18. It is not updated, it is easy to see and eye fatigue is reduced.

  Further, according to the digital camera 21 according to the present embodiment, when the external monitor 18 is connected to the external monitor interface 17, the operation accepting means detects that the digital camera 21 main body is tilted or shaken and displays an image. Since it automatically becomes a motion detection mode that accepts an operation of the user who selects the item, convenience is improved. In addition, the user can confirm the selected image while looking at the monitors 16 and 18 without looking at the hand for button operation by performing an operation of swinging or tilting the main body of the digital camera 21 to the left or right. , Operability is improved. Further, by associating the digital camera 21 itself with shaking or tilting and the moving direction of the selected image on the screens of the monitors 16 and 18, it is possible to operate the external monitor 18 intuitively and easily.

  Further, according to the digital camera 21 of the present embodiment, each image constituting the thumbnail list image displayed on the external monitor 18 has a built-in ratio of the size of each image to the screen size of the external monitor 18. Since the size of each image constituting the thumbnail list image displayed on the monitor 16 is set to be smaller than the ratio of the screen size of the built-in monitor 16, it is larger than the case where this ratio is the same. For this reason, when displaying the thumbnail list image on the external monitor 18 having a large screen such as the television 31, the user can grasp a summary of more images and a whole image at a glance.

  Next, a second embodiment in which the image display device according to the present invention is applied to a digital camera will be described.

  FIG. 10 is a diagram showing an outline of the back surface of the digital camera 21 according to the second embodiment, and FIG. 11 is a front view showing an outline of the front surface of the television 31 in the second embodiment.

  In the present embodiment, the thumbnail list images displayed on the built-in monitor 16 and the external monitor 18 are arranged and displayed in an arc shape different from the matrix shape in the first embodiment described above. This circular arc has a shape along the outer periphery of the multi selector 25 on the right side of the built-in monitor 16. The external monitor 18 includes, for example, a left column thumbnail list image composed of images 1a to 11a and a right column thumbnail list image composed of images 1b to 11b, which are classified into a plurality of columns based on the shooting date and time, the shooting number, and the like. It is displayed. Pressing the left end of the zoom button 22 selects the thumbnail list images 1a to 11a in the left column, and pressing the right end of the zoom button 22 selects the thumbnail list images 1b to 11b in the right column. . On the built-in monitor 16, for example, thumbnail list images 1 a to 11 a in the left column selected by the external monitor 18 by the operation of the zoom button 22 are displayed.

  In the present embodiment, the multi-selector 25 constitutes an operation accepting unit at the time of reproducing a captured image, and a user who selects an image in each thumbnail list image displayed on each monitor of the built-in monitor 16 and the external monitor 18. The operation of is accepted. By rotating the multi-selector 25, the selected image or thumbnail list image on the built-in monitor 16 and the external monitor 18 is switched as the circular arc rotates.

  The other configuration of the digital camera 21 according to the second embodiment is the same as that of the first embodiment described above.

  Also in the present embodiment, when the association between the selected images on the internal monitor 16 and the external monitor 18 by the association unit is set to association setting 1, the thumbnail display processing according to the flowchart shown in FIG. Is called.

  In other words, the currently selected image on each monitor 16, 18, for example, the image file name DSCN006. The operation accepting means accepts an operation for selecting an image next to the image 6a on which jpg is displayed, for example, the image 7a. When the determination shown in FIG. 7 and S22 is “YES”, the processing of S23 is performed, and the built-in monitor 16, the top image with the number 4a disappears, the display positions of the images with the numbers 5a to 8a are sequentially advanced, and the image with the number 5a is set as the top image. Then, the image of number 9a is newly entered at the rearmost position where the number is 8a, and five images of numbers 5a to 9a are displayed. In the external monitor 18, the top image with the number 1a disappears, the display positions of the images with the numbers 2a to 11a are sequentially advanced, and the image with the number 2a becomes the top image. Then, an image with the number 12a is newly entered at the rearmost position where the number is 11a, and 11 images with the numbers 2a to 12a are displayed. At this time, the selected images of the thumbnail list images on the built-in monitor 16 and the external monitor 18 are always at the same position (the center image position of the thumbnail list images in FIGS. 10 and 11) and do not move.

  Therefore, also in the digital camera 21 according to the second embodiment, when the association setting 1 is set, an operation for selecting the next image after the currently selected image on each of the monitors 16 and 18 is performed by the operation accepting unit. Even if accepted, the display position of each selected image in the thumbnail list image on each monitor 16, 18 does not move as described above, and each selected image is fixed at a fixed display position on the screen of each monitor 16, 18. ing. Therefore, when the user operates while viewing both the built-in monitor 16 and the external monitor 18, the display position of the selected image in each thumbnail list image can be easily grasped, and the thumbnail list of the built-in monitor 16 and the external monitor 18. It becomes easy to grasp the correspondence between images, and the screen operations of the monitors 16 and 18 are facilitated.

  Also in the present embodiment, when the association between the selected images on the internal monitor 16 and the external monitor 18 by the association unit described above is set to the association setting 2, the thumbnail display processing according to the flowchart shown in FIG. Is done.

  In other words, the next image after the currently selected image on each of the monitors 16 and 18, for example, the top image at the top of the left column (image 1a on the internal monitor 16 shown in FIG. 12 and image 1a on the external monitor 18 shown in FIG. 11). When an operation for selecting an image (image 2a on each of the monitors 16 and 18) is accepted by the operation accepting means, and the determination shown in FIG. 8, S32 is “YES”, the control unit 8 performs the operation in S33. It is determined whether or not it is an instruction to select the next image of the last image of the thumbnail list image of the monitor 16 (for example, the image of the number 5a at the lower end in FIG. 12).

  If this determination does not select the image next to the last image in the thumbnail list image and the determination in S33 is “NO”, the control unit 8 selects each of the internal monitor 16 and the external monitor 18 in S34. The position of the image is moved, and the next image (for example, the image 2a on each monitor 16, 18) is set as the selected image. On the other hand, the operation accepted by the operation accepting means is an instruction to select the next image from the image with the number 5a at the end of the thumbnail list image displayed on the built-in monitor 16, and the determination in S33 is “YES”. In this case, in step S35, the control unit 8 erases all the images of the thumbnail list images displayed on the built-in monitor 16 such as the numbers 1a to 5a, and deletes all the images, for example, the next new image group of the numbers 6a to 10a. And At the same time, the control unit 8 converts, for example, the images of numbers 1a to 11a constituting the thumbnail list image displayed on the external monitor 18 into five frames corresponding to the total number of thumbnail list images displayed on the built-in monitor 16. The display positions of the images of number 6a to 11a remaining after being erased are sequentially incremented by 5 frames, and the erased 5 frames are erased from the next display position of the image of number 11a, for example, at the last advanced position. For example, a new image group of numbers 12a to 16a is displayed.

  Next, in S36, the control unit 8 displays the selected images displayed on the built-in monitor 16 and the external monitor 18 at the top positions of the thumbnail list images displayed on the built-in monitor 16 and the external monitor 18, that is, Return to the top.

  Therefore, also in the digital camera 21 according to the second embodiment, when the association setting 2 is set, the selected image in the thumbnail list image displayed on the built-in monitor 16 is the next image from the last image of the thumbnail list image. When the operation accepting unit accepts an operation for switching to the image of the thumbnail list, the thumbnail list images displayed on the built-in monitor 16 and the external monitor 18 are simultaneously switched by the total number of thumbnail list images displayed on the built-in monitor 16. The correlation between the built-in monitor 16 and the external monitor 18 is easy to understand, and the simultaneous operation of the built-in monitor 16 and the external monitor 18 becomes easy. In addition, since the thumbnail list images of the monitors 16 and 18 are switched based on the built-in monitor 16, when the user operates the screen of the external monitor 18 based on the built-in monitor 16, the operation can be performed more easily. Become. Also, when the selected image is switched from the currently displayed image to the next image, the display position of each selected image in each thumbnail list image moves by one frame, and the previously selected image continues to be displayed. When it is desired to return to the selected image, it is convenient that the user can easily return while viewing the monitors 16 and 18 and display the previously selected image. Further, since the same thumbnail list image is continuously displayed on each monitor 16 and 18 until the position of the selected image is moved by the number of all thumbnail list images displayed on the built-in monitor 16, the entire thumbnail list image is displayed. It becomes easy to grasp the positional relationship between the selected images.

  Also in the present embodiment, when the association between the selected images on the internal monitor 16 and the external monitor 18 by the association means described above is set to the association setting 3, the thumbnail display processing according to the flowchart shown in FIG. Is done.

  In other words, the next image after the currently selected image on each of the monitors 16 and 18, for example, the top image at the top of the left column (image 1a on the internal monitor 16 shown in FIG. 12 and image 1a on the external monitor 18 shown in FIG. 11). When an operation for selecting an image (image 2a on each of the monitors 16 and 18) is accepted by the operation accepting means, and the determination shown in FIG. 9 and S42 is “YES”, the control unit 8 performs the operation in S43. It is determined whether or not it is an instruction to select the next image of the last image of the thumbnail list image of the monitor 16 (for example, the image of the number 5a at the lower end in FIG. 12).

  If this determination does not select the next image after the last image in the thumbnail list image and the determination in S43 is “NO”, the control unit 8 moves the position of the selected image on the built-in monitor 16 in S44. Then, the next image (for example, image 2a) is set as the selected image. On the other hand, the operation accepted by the operation accepting means is an instruction to select the next image from the image with the number 5a at the end of the thumbnail list image displayed on the built-in monitor 16, and the determination in S43 is “YES”. If there is, the control unit 8 deletes all the images having the number 1a to 5a, for example, constituting the thumbnail list image displayed on the built-in monitor 16 in S45, and deletes all the images to the next new image having the numbers 6a to 10a, for example. A group. Next, in S46, the selected image displayed on the built-in monitor 16 is returned to the top position of the thumbnail list image displayed on the built-in monitor 16.

  Next, in step S47, the control unit 8 selects the next image of the currently selected image as the last image of the thumbnail list image of the external monitor 18 (for example, the image with the number 11a at the bottom in FIG. 11). ) To determine whether the next image is an instruction to select the next image. If this determination is not an instruction to select the next image of the last thumbnail list image (for example, the image 11a) and the determination in S47 is “NO”, the control unit 8 performs external processing by the processing in S48. On the monitor 18, the selected image is switched to the next image (for example, the image 8a). On the other hand, the operation accepted by the operation accepting means is an instruction to select the next image from, for example, the number 11a at the end of the thumbnail list image displayed on the external monitor 18, and the determination in S47 is “YES”. In step S49, the control unit 8 deletes all the images having the thumbnail list images displayed on the external monitor 18 such as the numbers 1a to 11a in step S49, and deletes all the images, for example, next to the numbers 12a to 22a. Image group. Next, in S50, the selected image displayed on the external monitor 18 is returned to the top position of the thumbnail list image displayed on the external monitor 18.

  Therefore, also in the digital camera 21 according to the second embodiment, when the association setting 3 is set, the thumbnail list image displayed on the external monitor 18 is larger than the number of thumbnail list images displayed on the built-in monitor 16. Since the number of times of updating to the next thumbnail list image is less than the number of times of updating of the built-in monitor 16, the thumbnail list image is not complicatedly updated for the user who operates while viewing the external monitor 18, and is easy to see. , Eye fatigue is reduced.

  In the second embodiment, the zoom button 22 is operated to select thumbnail list images classified into a plurality of types by shooting date and time, shooting number, and the like. However, the front view of the television 31 shown in FIG. The thumbnail list images classified into the tree-like folders A, a, b, and c may be selected by designating the folders A, a, b, and c as shown in FIG. . When configured in this way, the thumbnail list image is managed for each folder, so that the user can easily grasp the entire stored thumbnail list image. Further, since the thumbnail list images 1b to 11b are displayed in association with the folder b as shown in the figure, the user can easily grasp the contents of the folder b intuitively, and each classified thumbnail list image is displayed. Thus, the efficiency of searching for one thumbnail list image is improved.
