  The electronic device 1 executes one predetermined data process among the second data process to the fourth data process described later. Note that the electronic apparatus 1 may be configured so that the user can select data processing from the second data processing to the fourth data processing.

(1) First data processing (change of icon display mode)
FIG. 4 is a diagram for describing the first data processing of the electronic device 1 when the electronic device 1 copies the image data included in the memory card 1091. Specifically, FIG. 4 is a diagram for explaining processing of the electronic device 1 in a case where finger images are not included in all the three-dimensional image generation data included in the memory card 1091. More specifically, FIG. 4 illustrates the processing when the finger image is not included in the left-eye image data and the right-eye image data constituting the three-dimensional image generation data for all the three-dimensional image generation data. It is a figure for doing.

  Referring to FIG. 4, memory card 1091 stores files A, B, D, F, G, and H, which are three-dimensional image generation data. The memory card 1091 stores files C and E, which are two-dimensional image data.

  When the electronic device 1 copies the eight files A to H stored in the memory card 1091, an object (specifically, for specifying the files A, B, D, F, G, and H in the three-dimensional file list) , File icon). Further, the electronic device 1 displays objects for specifying the files C and E in the two-dimensional file list based on the copy. Hereinafter, an object for specifying a file is also referred to as a “file icon”.

  In the following description, it is assumed in the electronic device 1 whether to display a three-dimensional file list or a two-dimensional file list based on the copy. The file list to be displayed can be switched based on a user instruction. In the following, a configuration in which a three-dimensional file list is displayed based on the copy and a two-dimensional file list is displayed when an instruction to switch the display target from the three-dimensional file list to the two-dimensional file list will be described as an example. Note that both file lists may be displayed based on the copy, or both file lists may be hidden.

  Since the electronic device 1 does not include a finger image in all the three-dimensional image generation data (files A, B, D, F, G, and H), the files A, B, D, F, G, and H Are displayed in a three-dimensional file list on the display 105. Further, the electronic device 1 displays the icons of the files C and E in a two-dimensional file list on the display 105.

(2) Second data processing (change of icon display mode)
FIG. 5 is a diagram for explaining the second data processing of the electronic device 1 when the electronic device 1 copies the image data included in the memory card 1091. Specifically, FIG. 5 is a diagram for explaining processing of the electronic device 1 in the case where there is an abnormality in the file D that is data for generating a three-dimensional image. Specifically, FIG. 5 is a diagram for describing processing of the electronic device 1 when one of the two viewpoint image data constituting the file D includes a finger image. . FIG. 5A shows an example of processing when the file D has an abnormality, and FIG. 5B shows another example of processing when the file D has an abnormality.

  Referring to FIG. 5A, the memory card 1091 stores files A, B, D, F, G, and H, which are three-dimensional image generation data, as in the case of FIG. The memory card 1091 stores files C and E, which are two-dimensional image data.

  When the electronic device 1 copies the eight files A to H stored in the memory card 1091, the image of the finger is included in the file D, so the icons of the files A, B, F, G, and H are usually displayed. Are displayed in the three-dimensional file list. In addition, the electronic device 1 displays the icon of the file D in the three-dimensional file list in a display mode different from the normal display mode. Specifically, the electronic apparatus 1 displays a mark 1051 indicating that the file D is a file that cannot be three-dimensionally displayed, attached to the icon of the file D. On the other hand, when the electronic device 1 receives the switching instruction, the electronic device 1 displays the icons of the files C and E in the two-dimensional file list.

  Thus, paying attention to one piece of data for three-dimensional image generation, the electronic device 1 has the following configuration. The electronic apparatus 1 determines whether one of the left-eye image data and the right-eye image data includes an image of an object that blocks external light from entering the image sensor. When the electronic device 1 determines that one of the left-eye image data and the right-eye image data includes a finger image, the electronic device 1 changes the display mode of the icon in the three-dimensional file list.

  Therefore, when the electronic apparatus 1 performs the data processing described with reference to FIG. 5A as an example of data processing, the user points to either the left-eye image data or the right-eye image data. It is possible to easily determine a file (three-dimensional image generation data) including the image without needing to visually recognize the three-dimensional image. Therefore, the electronic device 1 can perform file management that is highly convenient for the user.

  Note that the electronic device 1 generates 3D image data for the file identified by the icon with the mark 1051 (file D in FIG. 5A), and generates 3D image data. Instead of displaying an image based on the image, a two-dimensional image based on viewpoint image data not including a finger image is displayed. However, the present invention is not limited to this, and when the electronic device 1 selects a file specified by the icon with the mark 1051, a finger image is included, but the three-dimensional image data is generated. An image based on the three-dimensional image data may be displayed. It is preferable that the setting is selectable by the user.

  Referring to FIG. 5B, when electronic device 1 copies eight files A to H stored in memory card 1091, file D contains the images of the fingers, so files A, B, The icons of F, G, and H are displayed on the three-dimensional file list on the display 105 in a normal display mode. At this time, as described above, the electronic device 1 displays the icon of the file D in the three-dimensional file list in a display mode different from the normal display mode. Therefore, when the electronic device 1 performs the data processing described with reference to FIG. 5B as an example of the data processing, as in the data processing described with reference to FIG. A file containing a finger image in one of the left-eye image data and the right-eye image data can be easily determined without viewing a three-dimensional image.

  On the other hand, when the electronic device 1 receives a file list switching instruction, the electronic device 1 displays the icons of the files C and E in the two-dimensional file list. Furthermore, the electronic device 1 displays the icon of the file D in the two-dimensional file list. At this time, the electronic device 1 displays a mark 1052 indicating that the file D is a file that cannot be three-dimensionally displayed on the icon of the file D in the two-dimensional file list. As described above, the electronic device 1 is configured to display the icon (the icon of the file D) whose display mode is changed in the two-dimensional file list in addition to the configuration described with reference to FIG. Therefore, the user can easily determine that a file icon including a finger image is present in the two-dimensional file list.

  As described above, the electronic device 1 can perform file management that is convenient for the user.

  Note that the electronic device 1 generates 3D image data for the file identified by the icon with the mark 1052 (file D in FIG. 5B), and generates 3D image data. Instead of displaying an image based on the image, a two-dimensional image based on viewpoint image data not including a finger image is displayed. However, the present invention is not limited to this, and when the electronic device 1 selects a file specified by the icon with the mark 1052, a finger image is included, but the three-dimensional image data is generated. An image based on the three-dimensional image data may be displayed. It is preferable that the setting is selectable by the user.

(3) Third data processing (deletion of icons)
FIG. 6 is a diagram for explaining the third data processing of the electronic device 1 when the electronic device 1 copies the image data included in the memory card 1091. Specifically, FIG. 6 is a diagram for explaining processing of the electronic device 1 when there is an abnormality in the file D that is data for generating a three-dimensional image.

  Referring to FIG. 6, memory card 1091 stores files A, B, D, F, G, and H, which are three-dimensional image generation data, as in FIGS. The memory card 1091 stores files C and E, which are two-dimensional image data.

  When the electronic device 1 copies the eight files A to H stored in the memory card 1091, the image of the finger is included in the file D, so that the files A, B, D, and F are shown as the state α. , G, H icons are displayed in a three-dimensional file list in a normal display mode. On the other hand, when the electronic device 1 receives a file list switching instruction, the electronic device 1 displays the icons of the files C and E in the two-dimensional file list.

  After the electronic device 1 displays the file icon as in the state α, whether or not the finger image is included in all the three-dimensional image generation data (files A, B, D, F, G, and H). Determine whether. When the electronic device 1 determines that the image of the finger is included in the file D, the electronic device 1 deletes the icon of the file D from the three-dimensional file list if the three-dimensional file list is displayed. If the electronic device 1 determines that the image of the finger is included in the file D, the electronic device 1 displays the icon of the file D in the two-dimensional file list if the two-dimensional file list is displayed.

  Thus, paying attention to one piece of data for three-dimensional image generation, the electronic device 1 has the following configuration. The electronic apparatus 1 determines whether one of the left-eye image data and the right-eye image data includes an image of an object that blocks external light from entering the image sensor. When the electronic device 1 determines that either one of the left-eye image data and the right-eye image data includes a finger image, the electronic device 1 displays icons for the left-eye image data and the right-eye image data. Delete from the 3D file list. Further, the electronic device 1 is configured to display an icon deleted from the three-dimensional file list in the two-dimensional file list.

Therefore, the user can easily determine that a file icon including a finger image is present in the two-dimensional file list.

  As described above, the electronic device 1 can perform file management that is convenient for the user.

(4) Fourth data processing (change of icon display position)
FIG. 7 is a diagram for describing the fourth data processing of the electronic device 1 when the electronic device 1 copies the image data included in the memory card 1091. Specifically, FIG. 7 is a diagram for explaining processing of the electronic device 1 when there is an abnormality in the file D that is data for generating a three-dimensional image.

  Referring to FIG. 7, files A, B, D, F, G, and H, which are three-dimensional image generation data, are stored in memory card 1091 as in the case of FIGS. The memory card 1091 stores files C and E, which are two-dimensional image data.

  When the electronic device 1 copies the eight files A to H stored in the memory card 1091, the finger image is included in the file D. Therefore, the icons of the files A, B, D, F, G, and H are displayed. In the normal display mode, it is displayed on the three-dimensional file list. On the other hand, when receiving an instruction to switch the file list, the electronic device 1 displays the icon of the file D in the two-dimensional file list in addition to the icons of the files C and E. At this time, the electronic device 1 displays a mark 1052 indicating that the file D is a file that cannot be three-dimensionally displayed on the icon of the file D.

  Thus, paying attention to one piece of data for three-dimensional image generation, the electronic device 1 has the following configuration. The electronic apparatus 1 determines whether one of the left-eye image data and the right-eye image data includes an image of an object that blocks external light from entering the image sensor. When the electronic device 1 determines that either one of the left-eye image data and the right-eye image data includes a finger image, the electronic device 1 displays icons for the left-eye image data and the right-eye image data. Display in the 2D file list without displaying in the 3D file list.

It is possible to prevent the selected file from being selected from the three-dimensional file list.

  In addition, when displaying an icon of a file including a finger image in the two-dimensional file list, the electronic device 1 displays the icon in a manner different from that when displaying the icon in the three-dimensional file list. Therefore, the user can easily determine that a file icon including a finger image is present in the two-dimensional file list.

<F. Modification>
(F1. First modification)
(1) A determination is made as to whether or not a finger image is included in one of the left-eye image data and the right-eye image data, and the icons of the left-eye image data and the right-eye image data are first displayed. The electronic device 1 may be configured so that it is performed only once before being displayed on the screen 105.

  According to this configuration, each time the icons of the left-eye image data and the right-eye image data are displayed on the display 105, one of the left-eye image data and the right-eye image data includes a finger image. The data processing load of the electronic device 1 can be reduced as compared with the configuration for determining whether or not the electronic device 1 is present.

  (2) Further, a determination as to whether or not a finger image is included in one of the left-eye image data and the right-eye image data is generated using the left-eye image data and the right-eye image data. The electronic device 1 may be configured so that a three-dimensional image based on the three-dimensional image data is performed only once before being displayed on the display 105 for the first time. In other words, the electronic device 1 includes a finger image in one of the left-eye image data and the right-eye image data after receiving an instruction to display a three-dimensional image on the display regardless of whether the list is displayed. It may be determined whether or not it is.

  According to this configuration, every time a three-dimensional image based on three-dimensional image data generated using the left-eye image data and the right-eye image data is displayed on the display 105, the left-eye image data and the right-eye image data The data processing load of the electronic device 1 can be reduced as compared with the configuration in which it is determined whether or not a finger image is included in any one of the above.

(F2. Second modification)
In the above, the data processing of the electronic device 1 when the electronic device 1 acquires a still image file via the memory card 1091 has been described. Below, the data processing of the electronic device 1 when the electronic device 1 acquires a moving image file is demonstrated. Note that the method for obtaining a moving image file is the same as that for a still image (FIG. 3), and thus the description thereof will not be repeated here.

  (1) FIG. 15 is a diagram for explaining data processing of the electronic device 1 when the electronic device 1 acquires a moving image file.

  FIG. 15A is a diagram illustrating a case where a frame in which a finger is captured does not exist in each of the left-eye image data 801 and the right-eye image data 802. Referring to FIG. 15A, L (1) to L (10) represent left-eye frames, and R (1) to R (10) represent right-eye frames. The numbers in parentheses “()” indicate the playback order.

  FIG. 15B is a diagram illustrating a case where a frame in which a finger is captured exists in the left-eye image data 801. Referring to FIG. 15B, a finger is reflected in the seventh left-eye frame L (7) in the left-eye image data 801.

  In this way, when the image of the finger is included in the frame in one viewpoint image data (left-eye image data in FIG. 15) constituting the moving image file, the electronic device 1 performs the following processing. That is, the electronic device 1 shows the icon of the moving image file (that is, the image data for generating a three-dimensional image (left-eye image data and right-eye image data)) from the second data processing to the fourth data processing. Thus, for example, various data processing such as display in a two-dimensional file list, display with a mark 1051 in a three-dimensional file list, and deletion from the three-dimensional file list is performed (see FIGS. 5 to 7). That is, the electronic device 1 determines that the moving image file is an unsuitable file for three-dimensional reproduction, and notifies the user accordingly.

  Therefore, the electronic device 1 also includes a file in which the user includes a finger image in one of the left-eye frame and the right-eye frame, as in the case of data processing in a still image file. Can be prevented from being selected from the three-dimensional file list.

  (2) In the above, for example, as shown in FIG. 15B, if there is one frame including a finger in the left-eye image data 801, the above-described various data processing is performed. However, the present invention is not limited to this.

  FIG. 16 is a diagram for explaining another example of data processing of the electronic device 1 when the electronic device 1 acquires a moving image file. Specifically, FIG. 16 is a diagram illustrating a case where a plurality of frames in which a finger is captured are continuously present in the left-eye image data 801. Referring to FIG. 16, the sixth to ninth left eye frames L (6), L (7), L (8), and L (9) in left eye image data 801 include finger images. ing.

  The electronic device 1 performs the above-described data processing (the second data processing to the fourth data processing described with reference to FIGS. 5 to 7) when a frame including a finger image continues for a threshold Th or more in any viewpoint image data. Any one of the data processing). For example, when the threshold Th is “3”, the electronic device 1 displays the icon of the moving image file, for example, in a two-dimensional file list, with a mark 1051 in the three-dimensional file list. Various data processing such as deletion from the dimension file list is performed. That is, the electronic device 1 determines that the moving image file is an unsuitable file for three-dimensional reproduction, and notifies the user accordingly. The threshold value Th is stored in the flash memory 104.

  Therefore, the electronic device 1 has a three-dimensional image as compared with a configuration in which the icon is moved to a two-dimensional file list and no three-dimensional display is performed if there is even one frame including a finger. Can be fully enjoyed. Therefore, the electronic device 1 is excellent in user convenience. In addition, if the time is short, even if a three-dimensional image including a finger image is displayed on the display 105, the user may not be concerned. Therefore, the electronic device 1 can suppress the burden on the user's eyes and brain.

  (3) FIG. 17 is a diagram for explaining still another example of data processing of the electronic device 1 when the electronic device 1 acquires a moving image file. FIG. 17 is a diagram showing a case where a frame including a finger is present in the left-eye image data 801, as in FIG.

  When the electronic device 1 determines that a frame including a finger image is continuously included in one viewpoint image, the electronic device 1 determines a time t1 required to reproduce the continuous frame. When the determined time exceeds a threshold value Th relating to time, the electronic device 1 displays the icon of the moving image file in, for example, a two-dimensional file list and adds a mark 1051 in the three-dimensional file list. Various data processing such as display and deletion from the three-dimensional file list is performed. That is, the electronic device 1 determines that the moving image file is an unsuitable file for three-dimensional reproduction, and notifies the user accordingly.

  In this way, the electronic device 1 determines whether or not to perform predetermined data processing among the above-described data processing (FIGS. 5 to 7) based on the time required for reproduction, not the number of consecutive frames. You may judge.

Also in the present embodiment, the display contents of the three-dimensional file list and the display contents of the two-dimensional file list are the same as those in FIGS. 4 to 7 of the first embodiment. For this reason, the display contents of these file lists will not be described repeatedly. Hereinafter, differences from the processing of the first embodiment will be mainly described.

  Also in the present embodiment, electronic device 1 performs the same processing as the “first data processing” in the first embodiment. That is, as described with reference to FIG. 4, when the electronic device 1 does not include finger images in all the three-dimensional image generation data (files A, B, D, F, G, and H), When the three-dimensional file list is designated, the icons of the files A, B, D, F, G, and H are displayed on the three-dimensional file list on the display 105. Further, when the two-dimensional file list is designated, the electronic device 1 displays the icons of the files C and E in the two-dimensional file list on the display 105.

In the following description, for convenience of explanation, the case where both the viewpoint image data in the three-dimensional image generation data cannot be decoded will be described. That is, in the following, a case where one viewpoint image data cannot be decoded or both viewpoint image data can be decoded will be described.

(G1. Control structure in fifth data processing)
FIG. 18 is a flowchart when the electronic device 1 executes data processing corresponding to the data processing described with reference to FIG. 5A in the first embodiment. Referring to FIG. 18, in step S <b> 2, electronic device 1 acquires a plurality of files (for example, files A to G in FIG. 5A) via memory card 1091. In step S4, the electronic device 1 sets the value of the variable i to “1”. In step S6, the electronic device 1 decodes the i-th file. For example, when the i-th file is 3D image generation image data, the electronic device 1 decodes left-eye image data and right-eye image data associated with the left-eye image data.

  In step S8, the electronic apparatus 1 determines whether or not the decoded i-th file is a three-dimensional file (that is, three-dimensional image generation data). If electronic device 1 determines that the file is not a three-dimensional file (NO in step S8), the process proceeds to step S404. If the electronic device 1 determines that the file is a three-dimensional file (YES in step S8), in step S402, the bi-viewpoint image data (that is, left-eye image data and right-eye image data) that is the i-th file.

If electronic device 1 determines that a switching instruction has not been received (NO in step S20), it determines in step S22 whether an instruction to close the currently displayed file list has been received from the user.

  When electronic device 1 receives an instruction to close the file list (YES in step S22), the series of processing ends. If electronic device 1 determines that an instruction to close the file list has not been received (NO in step S22), the process proceeds to step S20.

  In the case of such a configuration, when the electronic apparatus 1 performs the data processing described with reference to FIG. 18, the user cannot decode either the left-eye image data or the right-eye image data (3 (Dimensional image generation data) can be easily determined without trying to visually recognize the three-dimensional image. Therefore, the electronic device 1 can perform file management that is highly convenient for the user.
