  FIG. 5 is a flowchart illustrating an example of display control of the display 110 in the digital camera 100. The processing shown in FIG. 5 is realized by the CPU 101 developing and executing a program stored in the internal storage device 102 in the memory 103.

  In FIG. 5, when the CPU 101 receives a display layout change instruction from the input unit 105 in step S <b> 201, the process proceeds to step S <b> 202.

  In step S202, the CPU 101 determines whether the layout change instruction in step S201 is an enlarged display or a reduced display. Then, the CPU 101 proceeds to step S203 in the case of reduced display, and proceeds to step S204 in the case of enlarged display.

  In step S203, the CPU 101 performs a display layout reduction process, controls the display control unit 104 to update the display screen of the display 110, and ends the process.

  Note that the display layout reduction process is to display a plurality of images when a single image is displayed on the display screen, or to a one-step reduced image when a single image is enlarged. When a plurality of images are displayed, the display screen is switched to display a larger number of images. Further, when the maximum number of images are displayed in one screen, the CPU 101 does not perform any processing and ends the processing.

  In step S204, the CPU 101 determines whether the image currently displayed on the display 110 is in a mode for displaying one image on one screen (one-screen playback mode). If the CPU 101 is not in the single-screen playback mode, the process proceeds to step S205. If it is in the single-screen playback mode, the process proceeds to step S206.

  In step S206, the CPU 101 determines whether the image currently displayed on the display 110 is an image in the MPF file. The CPU 101 proceeds to step S207 if the image is in the MPF file, and proceeds to step S205 if the image is an image other than the MPF file, for example, a normal image file such as JPEG format.

  In step S205, even if the display mode is a multiple-image display mode or a single-screen playback mode, the image is not an image in the MPF file, and the CPU 101 performs display layout enlargement processing. Then, the CPU 101 controls the display control unit 104 to update the display screen of the display 110 and ends the process.

  In the display layout enlargement process, when one image is displayed on the display screen of the display 110, a part of the display image is cut out and enlarged, and more than one image is displayed. A switching process for switching to display of a small number of images.

  In step S207, the CPU 101 switches the playback mode to the display format of the MPF playback mode, executes playback processing of the image stored in the MPF file, and ends the processing. The MPF playback mode is a mode in which a panorama image, a high dynamic range image, a continuously shot image, or the like stored in an MPF file is subjected to different playback processing depending on the type of image, and is used with reference to FIGS. Will be described in detail.

  FIG. 6 is a flowchart showing an operation example when the MPF playback mode in step S207 of FIG. 5 is the panorama display mode. In the panorama display mode, when one panorama image is formed from the four images of FIGS. 7A to 7D, the display control shown in FIG. 3 is realized.

  In FIG. 6, in step S <b> 301, when the CPU 101 receives an enlarged display instruction from the input unit 105 in a state where the panoramic image is displayed on one screen of the display 110 as illustrated in FIG. Panorama display is started, and the process proceeds to step S302. In the panorama display here, the CPU 101 enlarges the vertical direction of the image so as to match the height of the display 110 as shown in FIG. Move.

  In step S302, when the CPU 101 receives a display layout change instruction from the input unit 105, the process proceeds to step S303.

  In step S303, the CPU 101 determines whether the display layout change instruction in step S302 is an enlarged display or a reduced display. Then, the CPU 101 proceeds to step S304 in the case of reduced display, and proceeds to step S305 in the case of enlarged display.

  In step S304, the CPU 101 shifts to the normal reproduction mode and ends the process.

  In step S305, the CPU 101 switches the display format to a mode in which each image constituting the MPF file is individually displayed, and the process proceeds to step S306. At this time, as an image to be displayed on the display 110, an image including the most area of the portion displayed on the display 110 in the panorama display mode is automatically selected as the initial screen.

  In the example of FIG. 3, the image including the most part of the region displayed in FIG. 3B is the one shown in FIG. 7B, so that the mode for individually displaying each image constituting the MPF file is entered. The first image displayed on the display 110 after the transition is shown in FIG.

  In the mode in which images are individually displayed, the CPU 101 switches the display to an adjacent image in the MPF file in response to an image feed instruction from the input unit 105 and displays an image located at the end of the panoramic image. , An instruction to send the image outward is not accepted.

  In step S306, when the CPU 101 receives a display layout change instruction again, the process proceeds to step S307.

  In step S307, the CPU 101 determines whether the layout change instruction in step S306 is an enlarged display or a reduced display. Then, the CPU 101 proceeds to step S308 in the case of enlarged display, and proceeds to step S309 in the case of reduced display.

  In step S308, the CPU 101 enlarges and displays the image currently displayed on the display 110, updates the display screen, and returns to step S306.

  In step S309, the CPU 101 determines whether the image enlargement process currently displayed on the display 110 is being performed. If the CPU 101 has not performed the enlargement process, the process returns to step S301 to shift to the panorama display mode. If the enlargement process has been performed, the CPU 101 proceeds to step S310.

  In step S310, the CPU 101 reduces and displays the image currently displayed on the display 110 by one step, and returns to step S306 to continue the individual image display mode.

  FIG. 8 is a flowchart showing an operation example when the MPF reproduction mode in step S207 of FIG. 5 is the continuous shot image display mode. In the continuous image display mode, as shown in FIGS. 9A to 9E, when five images obtained by continuous shooting are stored in one MPF file, FIG. The display control shown in Fig. 2 is realized.

  In FIG. 8, in step S <b> 401, as shown in FIG. 4A, the CPU 101 gives an enlargement display instruction from the input unit 105 in a state where five images stored in the MPF file are displayed superimposed on the display 110. Is accepted, the MPF individual playback mode is entered. Then, the CPU 101 displays the top image of the images displayed in an overlapping manner on the display 110 (FIG. 4B), and proceeds to step S402.

  Unlike the above-described panoramic image, the continuous shot image does not need to generate and display a single image by combining a plurality of images, and thus shifts directly to the display format of the individual image display mode. Here, when an image forwarding instruction is received from the input unit 105, the CPU 101 changes the image to be displayed to an adjacent image in the MPF file, and updates the screen display of the display 110 (FIG. 4C). This image feed processing can be performed up to the end image (FIG. 9E) in the MPF file, and the image feed processing in a state where the image of FIG. 9E is displayed on the display 110 is invalid. It becomes.

  In step S402, when the CPU 101 receives a display layout change instruction, the process proceeds to step S403.

  In step S403, the CPU 101 determines whether the layout change instruction in step S402 is an enlarged display or a reduced display. Then, the CPU 101 proceeds to step S404 in the case of enlarged display, and proceeds to step S405 in the case of reduced display.

  In step S404, the CPU 101 performs an enlargement process on the image currently displayed on the display 110 (FIG. 4C), changes to the screen display shown in FIG. 4D, and returns to step S402.

  In step S405, the CPU 101 determines whether the image currently displayed on the display 110 is an image on which an enlarged display process is performed. Then, the CPU 101 proceeds to step S406 if the image is subjected to the enlarged display process, and proceeds to step S407 if the image is not subjected to the enlarged display process.

  In step S406, the CPU 101 performs a one-step reduction process on the image on which the enlargement display process is being performed, and returns to step S402.

  In step S407, the CPU 101 shifts to the normal reproduction mode, displays the image shown in FIG. 4A on the display 110, and ends the process.

  As described above, the present embodiment provides a user interface for performing an enlargement / reduction operation according to the type of individual image in the MPF file by an enlargement / reduction operation used for normal image reproduction. Therefore, the operability can be improved.

  Further, in the present embodiment, when shifting to the MPF reproduction mode, the display mode is changed for each type of individual image stored in the MPF file. When displaying a plurality of images in the MPF file in an environment where MPF files and normal image files are mixed, the plurality of images in the MPF file can be browsed without being developed. Further, when it is desired to confirm details of a plurality of images in the MPF file, it can be easily confirmed by an enlargement operation.

  In addition, this invention is not limited to what was illustrated to the said embodiment, In the range which does not deviate from the summary of this invention, it can change suitably.
