  Next, a free display operation, which is one of the operations performed by the digital camera having such a configuration, will be described in detail with reference to FIGS. 2, 3, 4, and 5. FIG. FIG. 2 is a flowchart showing the free display operation. 3, 4, and 6 are diagrams showing examples of display screens displayed on the display unit 6 during execution of this operation. FIG. 5 is a diagram for explaining image ranking performed in this operation.

  This free display operation is performed when the CPU of the system control unit 2 reads and executes a control program stored in the storage unit 9. The free display operation is an operation that starts when the free display mode is instructed by the operation of the operation unit 7 by the user.

  In FIG. 2, when starting this operation, the system control unit 2 first reads reduced image data (thumbnail image data) of a plurality of image files recorded on a memory card attached to the storage unit 17. A reduced image (also referred to as a thumbnail image) is displayed as a thumbnail on the display screen of the display unit 6 (step (hereinafter simply referred to as “S”) 1).

  FIG. 3 is a diagram showing an example of a display screen of the display unit 6 when thumbnails are displayed in S1. As shown in the figure, in this embodiment, 4 × 4 reduced images 1 to 16 are displayed. Note that, on this display screen, a reduced image of a plurality of other image files recorded on the memory card can be displayed by instructing a screen advance by operating the operation unit 7 by the user. ing.

  After S1, when an image selection instruction is given by the operation of the operation unit 7 by the user, a reduced image is selected according to the instruction (S2). In the selection of the reduced image in S2, the user selects a reduced image at the display position corresponding to the touch position by touching the desired reduced image displayed on the display screen with a finger via the touch panel 14. It is also possible to do so.

  FIG. 4 is a diagram illustrating an example of a display screen of the display unit 6 when a reduced image is selected in S2. As shown in the figure, in this embodiment, a check mark indicating that the selected reduced image (images 1, 3, 7, and 10 in the example shown in the figure) is selected at the lower left of the image. Displayed.

  In S2, the reduced image is selected according to the user's intention. For example, the reduced image may be automatically selected based on the content of the attached information of the image file, or randomly. It is possible to select automatically, or to select all. In S2, when the user selects a reduced image, the number of selectable reduced images can be limited in consideration of the area of the displayable area of the display unit 6.

  After S2, the reduced image data related to the reduced image selected in S2 and the attached information of the image file are extracted (S3), and the order determining unit 12 uses the attached information extracted in S3 and the like. Similarly, the reduced image data extracted in S3 is ranked (S4).

  FIG. 5 is a diagram for explaining the ranking performed in S4. In the figure, the degree of favorite, the number of times of browsing, and the shooting date are obtained from the attached information extracted in S3 (in the example of the figure, attached information of images 1, 3, 7, and 10). Here, the favorite degree can be arbitrarily designated by the user at the time of shooting or reproduction, and is registered or updated in the attached information each time the designation is made. The browsing count indicates the number of times that the reduced image is normally displayed on the display unit 6 (one frame display instead of thumbnail display), and is registered or updated in the attached information each time the display is performed. It is. The shooting date is the date when the reduced image was shot.

The check order is acquired when the user selects a reduced image in S2, and indicates the order in which the user selects the reduced image.
The display images can be ranked based on the information such as the degree of favorite, the number of browsing times, the shooting date, and the check order acquired in this way. In this embodiment, display images are ranked on the basis of the degree of favorite. As a result, the ranking is determined in the order of images 7, 1, 10, and 3 according to the degree of favorite as shown in FIG. It is assumed that the greater the numerical value, the higher the favorite degree.

In addition, the ranking can be performed randomly.
Subsequently to S4, the image size changing unit 2b subsequently determines the image size of the reduced image data extracted in S3 so that the higher the ranking, the larger the image size based on the ranking determined in S4. Is changed (S5). However, in this embodiment, it is assumed that even the highest ranking image is changed only to an image size of 80% of the displayable area of the display unit 6.

  Subsequently, the image angle of the reduced image data whose image size has been changed in S5 is changed within a range of ± 45 (S6). Here, + indicates the right rotation direction, and-indicates the left rotation direction. The image angle can be designated by the user arbitrarily within a range of ± 45 °, or can be automatically designated by the digital camera. For example, when the digital camera automatically designates, it is possible to designate at random within a range of ± 45 °. Alternatively, it may be specified according to the ranking.

In the present embodiment, the changeable image angle is in the range of ± 45 °, but the present invention is not limited to this.
Subsequently, an image position for displaying the reduced image related to the reduced image data whose image angle has been changed in S6 is determined (S7). However, the image position is determined so that the four corners of the reduced image to be displayed enter the displayable area of the display unit 6. The image position can be arbitrarily specified by the user, or can be automatically specified by the digital camera. For example, when the digital camera automatically designates, it can be designated at random. Alternatively, it may be specified according to the ranking.

  Subsequently, the image composition unit 2a displays the reduced image data in which the image size and the image angle have been changed in S5 and S6 at the image position determined in S7 in the foremost order. The combined image data is created by arranging and synthesizing (S8). The created composite image data is recorded on the memory card as an image file together with the attached information. Here, the attached information includes information such as the file name, selection mode, ranking, image size, image angle, and image position of the reduced image data used to create the composite image data. It is included, and the composite image can be reproduced from this attached information later.

Subsequently, the composite image related to the composite image data created in S8 is displayed on the display unit 6 (S9), and this flow ends.
FIG. 6 is a diagram illustrating an example of a display screen of the display unit 6 when a composite image is displayed in S9. As shown in the figure, the ranking determined in S4 (the order of images 7, 1, 10 and 3), the image size changed in S5, the image angle changed in S6, and determined in S7. According to the set image position, a higher ranking image is displayed larger in the foreground.

  As described above, according to this embodiment, when a plurality of images are displayed on one screen, the size and arrangement of each image can be changed and displayed. Moreover, since the higher the ranking, the larger the display, the higher the ranking of the desired image, and the easier viewing of the desired image can be made. Further, by displaying the composite image related to the composite image data recorded in the memory card, the user can view the desired image immediately at any time.

Further, by adopting a display method different from a simple enlarged image in this way, it is possible to provide the user with the pleasure of browsing the image.
In the present embodiment, in S5 described above, the image size is changed so that the higher the ranking, the larger the image size is displayed. is there.

In this embodiment, an operation (hereinafter referred to as “free display editing operation”) when editing the composite image data created by the free display operation shown in FIG. 2 will be described.
FIG. 7 is a flowchart illustrating the free display editing operation. 8, 9, 10, and 11 are diagrams for explaining operations on the touch panel 14 performed by the user during execution of this operation. FIG. 12 is a diagram illustrating an example of a display screen displayed on the display unit 6 by executing this operation.

  This free display editing operation is also performed when the CPU of the system control unit 2 reads and executes a control program stored in the storage unit 9. The free display editing operation is performed by the user using the operation unit 7 when the composite image related to the composite image data created by the free display operation shown in FIG. 2 is displayed on the display screen of the display unit 6. This operation starts when the free display editing mode is instructed by the operation.

  In FIG. 7, when starting this operation, the system control unit 2 first reads the attached information of the image file related to the composite image displayed on the display unit 6 and creates the composite image included in the attached information. The information such as the file name, ranking, image size, image angle, and image position is obtained for each reduced image used in the above. Subsequently, the reduced image data of the image file with the file name is read out from the memory card, and the read out reduced image data is read from the corresponding S5 to S6 in FIG. 2 based on the corresponding image size and image angle. Process. Then, the image placement unit 5c performs display control so that the reduced image related to the reduced image data after the processing is displayed at a corresponding position on the display screen based on the corresponding image position, and image duplication processing is performed. The unit 5d performs display control based on the corresponding ranking described above so that the higher ranking is displayed in the foreground. That is, display control is performed so that the higher the ranking, the higher the priority. As a result, instead of the composite image related to the composite image data, the display unit 6 displays an overlapping image composed of the reduced images related to the plurality of reduced image data reproduced based on the attached information.

  Subsequently, when the overlapping image is displayed, when the user touches a desired reduced image (except for the four corners of the reduced image) with the finger via the touch panel 14 (S11), the coordinate detection unit 15 performs the touch. The coordinates of the position are detected (S12), and the image specifying unit 2c specifies a reduced image touched (selected) by the user based on the coordinates of the touch position detected in S12 (S13).

  The coordinate system on the touch panel 14 corresponds to the coordinate system on the display screen of the display unit 6, and the position on the touch panel 14 can be specified to specify the corresponding position on the display screen. It can be done. Further, since the position, image size, and image angle of the displayed reduced image on the display screen are also known, the touch position on the touch panel 14 is specified, and thus the display screen corresponding to the touch position is displayed. It can be determined which of the displayed reduced images the position is included in, so that the reduced image selected by the user can be specified.

  FIG. 8 shows a state where the user touches the reduced image of “image 3” with the finger via the touch panel 14 in S11. Here, the x mark in the figure indicates the touch position of the user. Thereby, the reduced image of “image 3” is specified as the reduced image selected by the user.

  Subsequently to S13, when the user drags without releasing the finger that touched the touch panel 14 in S11, the drag amount detection unit 16 detects the coordinates of the touch position at the start of dragging (detected in S12), and at the end of dragging. From the coordinates of the touch position at the end of the drag detected by the coordinate detection unit 15, the movement component in the x direction and the movement component in the y direction are detected as the drag amount (movement amount and direction) (S14), and the image movement unit 5a. Moves the display position of the reduced image specified in S13 based on the drag amount detected in S14 (S15). However, the movement of the display position is limited to a range in which the reduced image is within the displayable area of the display unit 6.

  In other words, S14 is, in other words, coordinates that continuously change to the coordinates after the coordinates corresponding to the position when the image is specified by the image specifying unit 2c is detected by the coordinate detecting unit 15. When detected by the detection unit 15, as a drag amount, coordinates (drags) that continuously change from the coordinates corresponding to the position when the image is specified by the image specifying unit 2c (coordinates at the start of dragging) to the coordinates. It is also a process of detecting the movement amount and direction up to the coordinates at the end).

  FIG. 9 shows a state when the user drags the reduced image of “image 3” with the finger via the touch panel 14 in S14 to S15. Here, the reduced image of the dotted line “image 3” indicates the one at the start of the drag, and the reduced image of the solid line “image 3” indicates the one at the end of the drag. As a result, the reduced image of “image 3” moves to the position at the end of the drag.

  After S15, when the user subsequently touches the four corners of the desired reduced image with the finger via the touch panel 14, image rotation processing (S16) is started. In this image rotation process, first, when it is determined from the coordinates of the touch position detected by the coordinate detection unit 15 that the touch position is the four corners of the reduced image, rotation icons are displayed at the four corners of the reduced image. When the user touches and drags any of the rotation icons with the finger via the touch panel 14, the coordinate detection unit 15 detects the coordinates of the touch position, and then the drag amount detection unit 16 detects the detected touch position. Based on the coordinates, a movement component in the x direction and a movement component in the y direction are detected as a drag amount (movement amount and direction), and the image rotation unit 5b has a rotation direction and a rotation angle corresponding to the detected drag amount. Display control is performed so that the touched and dragged reduced image is rotated about the image center. The rotation direction is rotated left / right when the user drags the rotation icon at the upper right of the reduced image left / right, and rotates left / right when the rotation icon at the lower right of the reduced image is dragged up / down. When the rotation icon at the lower left of the reduced image is dragged to the right / left, it rotates left / right, and when the rotation icon at the upper left of the reduced image is dragged down / up, it rotates left / right. When the user touches another portion other than the reduced image or the reduced image via the touch panel 14, the touch position is a portion other than the other reduced image or the reduced image from the coordinates of the touch position detected by the coordinate detection unit 15. This image rotation process is terminated.

  FIG. 10 shows a state in which the user touches the lower right part of the reduced image of “Image 7” with the finger via the touch panel 14 before starting the image rotation process of S16. Here, the x mark in the figure indicates the touch position of the user. As a result, rotation icons are displayed at the four corners of the reduced image of “image 7”.

  FIG. 11 shows a state when the user touches and drags the rotation icon 18 in the lower right part of the reduced image of “image 7” with the finger via the touch panel 14. For example, when the user drags the rotation icon in the lower right portion with his / her finger through the touch panel 14 in the upward / downward direction, the reduced image of “image 7” is rotated left / right. In addition, the x mark of the figure has shown the rotating shaft at this time.

  After S16, when an instruction to finish editing is given by the operation of the operation unit 7 by the user, the editing is finished and confirmed, and the image composition unit 2a displays the composite image data of the overlapped image displayed at this time. Create (S17). That is, the reduced image data related to the reduced image included in the overlapping image displayed at this time is synthesized (re-synthesized) so that the overlapping image becomes one image as it is, and synthesized image data (re-synthesized image data) Create

  Subsequently, the recomposed image related to the recombined image data created in S17 is displayed on the display screen of the display unit 6, and the composite image data and the attached information of the composite image file recorded in the memory card are edited. The subsequent composite image data (recombined image data) and post-edit information (image position, image angle, etc.) are updated to the attached information (S18), and this flow ends.

  FIG. 12 is a diagram illustrating an example of a display screen of the display unit 6 when a recombined image is displayed in S18. As shown in the figure, after the image is moved in S15 and rotated in S16 (see, for example, FIGS. 8 to 11), the edited composite image is displayed.

As described above, according to the present embodiment, the composite image can be easily changed according to the user's preference, and the desired image can be browsed in the desired arrangement at any time.
In this embodiment, the image file related to the composite image data before editing is updated to the image file related to the recombined image data after editing. In addition, it is also possible to newly create image data relating to recombined image data after editing.

  In this embodiment, based on the attached information of the composite image file recorded on the memory card, the operation when creating composite image data using the main image data of the reduced image used to create the composite image (hereinafter referred to as “ High-resolution composite image creation operation ”).

  FIG. 13 is a flowchart illustrating a high-definition composite image creation operation. FIG. 14 is a diagram illustrating an example of attached information. FIG. 15 is a diagram for explaining the relationship between attached information and a composite image.

  This high-definition composite image creation operation is also performed by the CPU of the system control unit 2 reading and executing a control program stored in the storage unit 9. The high-definition composite image creation operation is performed by the user using the operation unit 7 when the composite image data is recorded on the memory card by the free display operation shown in FIG. 2 or the free display edit operation shown in FIG. This operation starts when a high-definition composite image creation mode is instructed by the operation.

  In FIG. 13, when starting this operation, the system control unit 2 first performs a composite image name acquisition process (S21). In this composite image name acquisition process, when the file name of an image file related to a desired composite image is designated by the operation of the operation unit 7 by the user, the file name is acquired.

Subsequently, the attached information of the image file having the file name acquired in S21 is acquired from the memory card. (S22).
FIG. 14 is a diagram illustrating an example of attached information acquired in S22. As shown in the figure, the attached information includes a file name (image file name) and any selection method (selected image, metadata selection, random selection) for each reduced image data used to create the composite image. , Or all image selection), information such as whether or not a reduced image has been selected, an image order, a selection number, a reduced image size, an image start coordinate, an angle reference, and an image angle are included. Further, although not shown, information on the image size of the composite image is also included.

  Here, in each of the selected image, metadata selection, random selection, and all image selection items, ON (= 1) indicates a selection method that is used, and OFF (= 0) indicates a selection method that is not used. Show. In the example shown in the figure, the selection method used is a selection image. As described in S2 of FIG. 1, the selected image indicates a selection method arbitrarily selected by the user, the metadata selection indicates a selection method selected based on attached information, and the random selection is a selection selected randomly. A method is shown, and all image selection indicates a selection method for selecting all images.

Further, the image ranking indicates the above-described ranking value, the selection number indicates the order of selection, the image start coordinate indicates the above-described image position, and the angle reference indicates the position of the image serving as the reference for the image angle.
FIG. 15 is a diagram for explaining the relationship between the attached information shown in FIG. 14 and the composite image, and shows a display screen when the composite image of the image file having the attached information is displayed on the display unit 6. . As shown in FIG. 15, in the coordinate system on the display screen, the upper left corner of the display screen is the origin (0, 0), the horizontal direction is the x direction, and the vertical direction is the y direction. Here, for example, when focusing on the reduced image of “image 7”, the reduced image size “240 × 380” is the image of “image 7” in the information related to “image 7” (“0000000.jpg”) included in the attached information. The image start coordinates “130, 190” are the upper left coordinates of “image 7”, the angle reference “lower left” is the lower left corner of “image 7”, and the image angle “−15” is the “image”. This is an angle θ formed by a straight line passing through the lower left of 7 ″ and parallel to the x direction and the lower side of “Image 7”. However, in the image angle, + is a clockwise direction and-is a counterclockwise direction.

  Returning to FIG. 13, after S22, the file name of the reduced image included in the attached information acquired in S22 is acquired, and the main image data of the image file having the acquired file name is read from the memory card (S23). ). That is, the original image data of the reduced image used for creating the composite image is called up.

  Subsequently, automatic editing processing for editing the main image data read in S23 based on the attached information acquired in S22 is performed (S24). In this automatic editing process, the ratio of the image size and the image angle of the main image in the composite image to the composite image related to the composite image data created using the main image data in S25 is the file name specified in S21. The image size of the composite image included in the attached information acquired in S22 so that the ratio and the image angle of the reduced image in the composite image with respect to the composite image related to the composite image data of the image file are the same as the image angle. The image size and image angle of the main image data read in S23 are changed based on the information such as the image size and image angle of the reduced image in the combined image. The image size is changed by the image size changing unit 2b.

However, in this embodiment, the image size of the composite image data created using the main image data is set to be twice that of the main image data.
Subsequently, an image composition storage process is performed in which the main image data that has been subjected to the automatic editing process in S24 is combined and stored based on the attached information acquired in S22 (S25). In this image composition saving process, the arrangement of the main image in the composite image with respect to the composite image related to the composite image data created using the main image data that has been subjected to the automatic editing process in S24 is the file designated in S21. The image size of the composite image and the size of the reduced image in the composite image included in the attached information acquired in S22 so as to be the same as the arrangement of the reduced image in the composite image with respect to the composite image related to the name image file Based on the information such as the image size and the image start coordinates, the image composition unit 2a composes the main image data that has been subjected to the automatic editing process in S24 and creates composite image data. Note that in the creation of the composite image data, arrangement and synthesis are performed such that the higher rankings are displayed in the foreground based on the information such as the image ranking included in the attached information acquired in S22. Then, the created composite image data is recorded on the memory card as an image file together with new additional information related to the composite image data, and this flow is finished.

  As described above, according to the present embodiment, when the composite image is printed or displayed on a high-definition display device such as a PC, the composite image data created using the main image data is used. The printing or display can be performed with high image quality.

  In this embodiment, when the composite image related to the composite image data created by the free display operation shown in FIG. 2 or the free display edit operation shown in FIG. 7 is displayed on the display screen of the display unit 6, An operation when the composite image display format is changed to a certain format (hereinafter referred to as “display format change operation”) will be described.

  This display format changing operation is also performed when the CPU of the system control unit 2 reads and executes a control program stored in the storage unit 9. Further, in this display format changing operation, a composite image related to the composite image data created by the free display operation shown in FIG. 2 or the free display editing operation shown in FIG. 7 is displayed on the display screen of the display unit 6. Sometimes, the operation is started when the display format change mode is instructed by the operation of the operation unit 7 by the user.

FIG. 16 is a diagram for explaining the display format changing operation.
As shown in the figure, in this operation, in the composite image displayed on the display screen of the display unit 6, the user designates a desired reduced image (here, a reduced image of “image 1”) via the touch panel 14. (See the display screen 19 on the upper side of the figure), the touched reduced image is displayed large at the approximate center of the display screen, and the remaining reduced images are displayed small in the corners without changing the image angle (see FIG. (See display screen 20 on the lower side of the figure). At this time, when the reduced image touched by the user is touched again via the touch panel 14, the original composite image (see the display screen 19 on the upper side of the figure) is restored.

  The display format changing operation will be described in more detail. First, when the user touches a desired reduced image with a finger via the touch panel 14, the coordinate detection unit 15 detects the coordinates of the touch position, and the image specifying unit 2c. Specifies a reduced image touched (selected) by the user based on the coordinates of the detected touch position.

  Subsequently, the attached information of the image file related to the composite image displayed on the display unit 6 is read, and the file name, the image angle, etc. for each reduced image used to create the composite image are included in the attached information. The information is obtained, the reduced image data of the image file with the file name is read from the memory card, and the corresponding image angle is not changed with respect to the read reduced image data, and only the image size is specified as described above. The above-described processes of S5 to S6 in FIG. 2 are performed so that the reduced image is displayed larger and other reduced images are displayed smaller. Then, the image arrangement unit 5c performs display control so that the reduced image related to the reduced image data after the processing is displayed so that the above-described specified reduced image is displayed at the approximate center and another reduced image is displayed at the corner. As a result, instead of the composite image related to the composite image data, the specified reduced image is displayed at the approximate center and other reduced images are displayed at the corners on the display unit 6.

  After that, when the user touches the reduced image displayed largely in the center with his / her finger through the touch panel 14 again, the coordinate detection unit 15 detects the coordinates of the touch position, and the image specifying unit 2c Based on the coordinates of the detected touch position, it is specified that the reduced image touched (selected) by the user is a reduced image displayed largely at the center. As described above, when the reduced image touched by the user is specified to be a reduced image displayed largely at the center, a combined image related to the previously displayed combined image data is displayed on the display unit 9.

  In FIG. 14, when the display screen 19 is displayed, the user does not display a reduced image of “image 1” displayed large at the center, for example, but displays a small image at the corner. When the reduced image related to “Image 10” is touched with a finger via the touch panel 14, the reduced image of “Image 10” is displayed in a large size in the approximate center instead of the reduced image of “Image 1”, and the reduced image of “Image 1” is displayed. It is also possible to display the image small in the corner instead of the reduced image of “image 10”, for example.

  As described above, according to the present embodiment, when the desired reduced image is displayed small in the composite image displayed on the display unit 6, the user can easily enlarge it and browse it.

  In the present embodiment, when the composite image related to the composite image data created by the free display operation shown in FIG. 2 or the free display edit operation shown in FIG. 7 is displayed on the display screen of the display unit 6, An operation for changing (returning) the format to the thumbnail display (hereinafter referred to as “thumbnail display changing operation”) will be described.

  This thumbnail display change operation is also performed by the CPU of the system control unit 2 reading and executing the control program stored in the storage unit 9. Further, in this thumbnail display changing operation, a composite image related to the composite image data created by the free display operation shown in FIG. 2 or the free display editing operation shown in FIG. 7 is displayed on the display screen of the display unit 6. Sometimes, the operation is started when an instruction to switch to thumbnail display is made by the operation of the operation unit 7 by the user.

FIG. 17 is a diagram illustrating a display screen of the display unit 6 after the thumbnail display change operation is performed. In this embodiment as well, the thumbnail display is a 4 × 4 thumbnail display.
As shown in the figure, when an instruction to switch to thumbnail display is given, reduced images ("image 7" in the figure), which are included in the composite image (here, the composite image shown in FIG. 6), In addition to “image 1”, “image 10”, and “image 3” (reduced images), reduced images related to other image files recorded on the memory card are displayed as thumbnails.

  However, in this thumbnail display, the reduced images included in the composite image are displayed in order according to the ranking (here, the degree of favorite), and the other reduced images are, for example, the attached information of the image file. They are displayed in order based on the contents (shooting date, etc.).

  The thumbnail display changing operation will be described in more detail. When a composite image is displayed on the display screen, first, when a user instructs to switch to thumbnail display by operating the operation unit 7, the memory card Based on the attached information of the image file related to the composite image, the reduced image data related to the reduced image used to create the composite image is read out, and the reduced image data of the remaining image files that can be displayed as thumbnails is read out. . Then, among the reduced images related to the read reduced image data, the reduced images used for creating the composite image are displayed in order from the upper left of the display screen according to the ranking included in the attached information, The remaining reduced images are displayed as thumbnails by sequentially displaying the reduced images used for creating the composite image based on the attached information (for example, the shooting date) included in the attached information.

  As described above, according to the present embodiment, the reduced images are displayed in order according to the ranking such as the degree of favorite, and subsequently, are sequentially displayed based on the contents of the attached information other than the ranking (for example, the shooting date). Thumbnail display.

  In the present embodiment, when a composite image is displayed, an instruction to switch to thumbnail display is given. For example, when normal thumbnail display is performed as shown in FIG. In addition, after the user selects a desired reduced image as shown in FIG. 4, the user can perform a predetermined operation to display thumbnails in the format shown in FIG. is there.

In the present embodiment, an image display apparatus capable of reproducing content data such as music data and book data in addition to image data will be described.
The image display apparatus according to the present embodiment includes a touch panel on the display screen of the display unit as well as an operation unit including various switches and buttons, for example, like the digital camera shown in FIG.

  Similarly, in this display screen, when any selection is not requested and the virtual decision button 22 has no decision role, when the virtual decision button 22 is pressed via the touch panel, the image reproduction mode is selected. The display screen is switched to a display screen (for example, the display screen of FIG. 16) according to the image playback mode.

FIG. 20 is a flowchart showing a display operation including an operation related to such screen switching.
In the same figure, the operation related to the screen switching is performed by the processing of S36 to S40. The processing of S31 to S35 will be described later.

  In this operation, it is determined whether any selection decision is requested (whether no selection is requested and the virtual decision button 22 does not have a decision role) (S31). If the determination result is Yes, the process returns to S31, and if No, the process proceeds to S37.

In subsequent S37, it is determined whether or not the virtual determination button 22 has been pressed via the touch panel. If the determination result is Yes, the process proceeds to S38, and if it is No, the process returns to S31.
In subsequent S38, it is determined whether or not the display screen is an image function screen (display screen corresponding to the image playback mode). If the determination result is Yes, then the music function screen (corresponding to the music playback mode) is determined. (Display screen) (S39), in the case of No, subsequently, the screen is switched to the image function screen (display screen corresponding to the image reproduction mode) (S40).

Then, when the process of S39 or S40 ends, the process returns to S31.
The display screen is switched by such processing.
In this image reproducing apparatus, the color of the frame of the display screen is changed according to the data capacity of image data, music data, etc. recorded on the recording medium.

Such an operation of changing the color of the frame of the display screen is performed by the processes of S31 to S35 in FIG.
In this operation, it is determined whether or not the display screen is an image function screen (S 31). If the determination result is Yes, then the storage area of the recording medium that can be used for images has a free space of 10% or more. It is determined whether or not there is (S32), and if the determination result is Yes, the process proceeds to S36, and if it is No, then the outermost side of each side on the image function screen (current display screen). Is displayed in red (S33) and the process proceeds to S36.

  On the other hand, in the determination of S31, if the determination result is No, it is subsequently determined whether or not the storage area of the recording medium that can be used for music has 10% or more (S32). If the result is Yes, the process proceeds to S36. If the result is No, the outermost side of each side is displayed in red on the music function screen (current display screen) (S33), and the process proceeds to S36.

  As a result, when the storage area of the recording medium that can be used for images or music becomes less than 10%, the outer frame of the display screen is displayed in red, and the user has less than 10% of the storage area. Can know.

FIG. 21 is a diagram showing an example of an image function screen in which the outer frame is displayed in red by this operation. In the example of the figure, the outer frame 23 is displayed in red.
In this example, the outer frame of the display screen is displayed in red when the storage area is less than 10%. However, the threshold is not limited to 10%, and the color of the outer frame is limited to red. It is not something that can be done. For example, if the color of the frame is a semi-transparent color, the user can also view the image of the part corresponding to the part of the frame. Alternatively, it is possible to display in stages such that the storage area is less than 30% yellow and less than 10% red. Also in this case, the threshold value and the frame color are not limited to these.

  In this example, the outer frame of the display screen is displayed in red to notify the user that the free space in the storage area is less than 10%. It is also possible to notify with an indicator or the like displayed on the display screen. Alternatively, the color of the virtual cross button 21 can be changed according to the amount of use of the storage area. Alternatively, it is possible to turn on an LED of a predetermined color provided in a predetermined button included in the operation unit in accordance with the amount of use of the storage area.
