2. Display method [Display method 1]
(Display example 1)
Next, the display method 1 in the display device 100 will be described with reference to FIG. FIG. 4 is a flowchart for explaining the thumbnail image display method 1, and shows a flow of processing executed by the display device 100. The components of the display device 100 will be described with the same reference numerals as above.

  First, the control unit 110 selects thumbnail bundles 21, 22, 23, 24 and thumbnail bundles 21, 22, 23, 24 to be displayed as a search screen from a plurality of book data and electronic photo files stored in the storage unit 160. The file data corresponding to the thumbnail images 11 and 12 and the like constituting the file are read (step S201). When the operation unit 150 performs an operation of selecting one of a plurality of book data and electrophotographic data stored in the storage unit 160, the control unit 110 stores the selected data in the storage unit 160. Read from.

  Next, the control unit 110 supplies the data of each page of the file data read from the storage unit 160 to the thumbnail image generation unit 120 (step S202). The thumbnail image generation unit 120 generates thumbnail images 11 and 12 of each page rendered based on the received data of each page, and supplies the thumbnail images 11 and 12 of each page to the display image generation unit 130 (step S203).

  Note that the thumbnail images 11 and 12 as images are arranged on a first virtual axis along the first direction of the screen configuring the display unit 140, intersect the first virtual axis, It is an image displayed by rotating around a second virtual axis along the second direction of the screen configuring the display unit 140, and further rotating around the first virtual axis. As described above, the thumbnail images 11 and 12 are rotated about the second virtual axis and the first virtual axis, so that when the screen is directly faced to the user in a readable state, The thumbnail bundles 21, 22, 23, and 24 composed of a plurality of thumbnail images 11 and 12 are transformed into a state in which they can be overlooked. That is, the user views the thumbnail images 11, 12, etc. included in the thumbnail bundles 21, 22, 23, 24, etc. obliquely from above so that the user can see the page in the same manner as when looking down. The thumbnail images 11 and 12 of the page are modified.

  Here, the process of deforming the thumbnail image will be described with reference to FIGS. 5A, 5B, 5C, 5D, and 5E. 5A to 5E are diagrams for explaining the process of deforming the thumbnail image. In the description of the process of deforming the thumbnail image, the reference numerals (11, 12) of the thumbnail image given above are omitted.

  Each thumbnail image supplied from the thumbnail image generation unit 120 is an image in which each page such as a book or an electronic photograph is viewed in plan. As shown in FIG. 5B, the vertical length is L and the horizontal length is L. It is the image 11b which made S into. In other words, in the image 11b, the vertical side is parallel to the vertical direction of the display area along the second direction of the display section 140, and the horizontal side is along the first direction of the display section 140. It is configured to be parallel to the horizontal direction of the display area.

  The thumbnail image generation unit 120 generates an image obtained by transforming each thumbnail image representing each page such as a book or an electronic photograph. Specifically, for each page, the thumbnail image generation unit 120 vertically arranges the page 11a on the first virtual axis Q set on the virtual horizontal plane N in the virtual space, as shown in FIG. 5A. The second virtual axis M intersecting the first virtual axis Q is rotated at a rotation angle θ from the reference position 11 in which the horizontal direction of the page 11a is parallel to the horizontal direction of the display area. Further, the thumbnail image generation unit 120 rotates the page 11a rotated about each second virtual axis M in the virtual space at the depression angle φ (not shown) about the first virtual axis Q. The generated image is generated. That is, the thumbnail image generation unit 120 obliquely tilts the page 11a at a depression angle φ (not shown) from the viewpoint above the upper side of the page 11a rotated about the second virtual axis M in the virtual space. Generate the image looking down. In other words, an image obtained by transforming each thumbnail image is generated as a bird's-eye view of the page 11a in the virtual space from a viewpoint above the upper side of the page 11a by obliquely observing the page 11a at a depression angle φ (not shown). When the page is not rotated, the horizontal direction of the page is parallel to the horizontal direction (first direction) of the display area, and the rotation angle θ is 0 °. In addition, the depression angle φ is a predetermined angle. Further, the second virtual axis M is not limited to the configuration in which the second virtual axis M is parallel to the side in the vertical direction (second direction) of the page, but may be configured to intersect the side in the horizontal direction of the page. Good.

  Specifically, first, the thumbnail image generation unit 120 does not change the horizontal width of the image 11b in which each page is viewed from the front (see FIG. 5B), and the vertical direction is set as shown in FIG. 5C. By deforming the image 11b in FIG. 5B, the right side is shifted from the left side by S · sin θ · tan φ to generate an image 11c. Next, as shown in FIG. 5D, the thumbnail image generation unit 120 generates an image 11d obtained by horizontally reducing the image 11c of FIG. 5C by a magnification of cos θ. As a result, the width of the image 11d becomes S · cos θ. Then, finally, as shown in FIG. 5E, the thumbnail image generation unit 120 generates an image 11e obtained by reducing the image 11d of FIG. 5D in the vertical direction by a magnification of cos φ. As a result, the size of the image 11e in the vertical direction is L · cosφ. As a result, an image 11e is obtained in which the page is rotated about the second virtual axis M at the rotation angle θ and further rotated about the first virtual axis Q. In other words, the image 11e is obtained when the page is rotated about the second virtual axis M at the rotation angle θ and the page is looked down at the depression angle φ from the viewpoint above the upper side of the page.

  The rotation angle θ is set to a predetermined rotation angle θ1 for the selected page specified by the selection page data, and is set to a predetermined rotation angle −θ1 for the page immediately before the selection page. .. For pages other than the selected page, the rotation angle θ is gradually increased as the page number moves away from the selected page, and the rotation angle θ of the pages after the selected page is θ1 <θ in this embodiment. Within the range of <90 °, the rotation angle θ of the page before the selected page is set within the range of −θ1> −θ> −90 ° in the present embodiment. The selected page here is a page for displaying the spread state, and includes, for example, a page selected by the user to be displayed as the representative thumbnail images 31, 32, 33, 34, or a cover page.

  Returning to FIG. 4, the display image generation unit 130 generates a plurality of image bundles in which the thumbnail images 11 and 12 of the respective pages supplied from the thumbnail image generation unit 120 are arranged so as to be arranged in the first direction ( Step S204). In this configuration, thumbnail bundles 21, 22, 23, 24 are illustrated as the plurality of image bundles.

  Then, the display image generation unit 130 generates a display image in which the thumbnail bundles 21, 22, 23, and 24 generated as a plurality of image bundles are arranged along the second direction intersecting the first direction (step). S205). Here, the display image generation unit 130 partially superimposes the plurality of modified thumbnail images 11 and 12 and the like on adjacent images, and the images are separated as the distance from the thumbnail image 11 of the cover page increases. It includes an area m arranged so as to have a narrow interval between them, and an area s arranged between the predetermined position and the thumbnail image 12 of the last page and in which each image is arranged in parallel at a predetermined interval. The thumbnail bundle 21 is arranged. The other thumbnail bundles 22, 23, 24 are also configured by arranging a plurality of similar thumbnail images 11, 12, etc.

  In step S205, the display image generation unit 130 also selects a user-selected selection page (hereinafter referred to as a selection page) that is arranged side by side along the first direction of the thumbnail bundles 21, 22, 23, and 24. Alternatively, representative thumbnail images 31, 32, 33, 34 are generated as display images of representative pages such as covers. At this time, the display image generation unit 130 uses the file names n1, n2, n3, and n4 representing the contents of the thumbnail bundles 21, 22, 23, and 24 as the display image of the selected page or a representative page such as a cover page. It is generated as an image to be displayed in an overlapping manner. The file names n1, n2, n3 and n4 can be paraphrased as document names.

  Further, in step S205, the display image generation unit 130 corresponds to a selected page arranged side by side along the first direction of the thumbnail bundles 21, 22, 23, 24, or a representative page such as a cover. Each of the representative thumbnail images 31, 32, 33, and 34 is a so-called gradation display image in which the color tone is changed as it goes downward from above as indicated by arrows f1, f2, f3, and f4 in FIG. To generate. In the display example 1 shown in FIG. 3, the light color tone is gradually changed to the dark color tone as it goes downward. By such gradation display, it becomes easy to distinguish the division between the display images of the selected pages adjacent to each other in the vertical direction, which is the vertical direction along the second direction, or the representative page such as the cover, and the visibility is improved. be able to. Further, by such gradation display, when the file names n1, n2, n3, and n4 are displayed in outline characters, the representative thumbnail images 31, 32, 33, 34 and the file names n1, which are dark display parts, are displayed. The comparison with n2, n3, n4 becomes clear, and the file names n1, n2, n3, n4 can be made easy to see.

  Then, the control unit 110 displays various display images generated by the display image generation unit 130 on the display unit 140 (step S206), and ends the series of processes. Note that the display here is arranged on the first virtual axis Q along the first direction shown in FIGS. 5A to 5E, intersects with the first virtual axis Q, and is displayed along the second direction. A plurality of images 11e displayed by being rotated around two virtual axes M are used. Then, as shown in FIG. 3, the control unit 110 causes the display unit 140 to display thumbnail bundles 21, 22, 23, 24 as image bundles composed of the thumbnail images 11, 12 that are the images 11e. To do. Specifically, the control unit 110 sets the plurality of thumbnail bundles 21, 22, 23, 24 in which the plurality of thumbnail images 11, 12 and the like are arranged side by side in the first direction (X axis in the drawing) as the first thumbnail bundle. It is arranged and displayed along a second direction (Y axis in the drawing) intersecting the direction.

  According to the display method of the display example 1 as described above, the display unit 140 is arranged on the first virtual axis along the first direction (X axis) which is the horizontal direction of the screen constituting the display unit 140. An image obtained by rotating about a second virtual axis along a second direction (Y axis) intersecting the virtual axis of, and further rotating about the first virtual axis, that is, a page view in the virtual space. The thumbnail bundles 21, 22, 23, and 24 using the thumbnail images 11 and 12 as a plurality of images that are the generated images are generated and displayed. The thumbnail bundles 21, 22, 23, and 24, which are image bundles in which the thumbnail images 11 and 12 are arranged in the first direction, are arranged in a second direction (Y-axis) that intersects the first direction (X-axis). ) Are displayed along with multiple arrangements. As a result, more thumbnail bundles 21, 22, 23, 24, thumbnail images 11, 12, etc. can be displayed in the limited display area of the display unit 140. In this way, even in the limited display area of the display unit 140, the entire contents of the image bundle, in other words, the entire contents of the folder or file that is an aggregate of each page can be viewed.

FIG. 6 is a flowchart for explaining the thumbnail image display method 2, and shows the flow of processing executed by the display device 100. FIG. 7A is a diagram showing a second display example of thumbnail bundles including thumbnail images. FIG. 7B is a diagram illustrating the display change operation of display example 2. FIG. 7C is a diagram illustrating another display change operation of display example 2. In the description of the display method 2 and the display example 2, constituent parts of the display device 100 will be described with the same reference numerals as above.

  As shown in FIGS. 6 and 7A, first, like the display method 1, the control unit 110 displays a thumbnail bundle to be displayed as a search screen from a plurality of book data and electronic photo files stored in the storage unit 160. File data corresponding to the thumbnail images 11 and the like forming the 21, 22, 23, 24 and the thumbnail bundles 21, 22, 23, 24 are read (step S301). When the operation unit 150 performs an operation of selecting one of a plurality of book data and electrophotographic data stored in the storage unit 160, the control unit 110 stores the selected data in the storage unit 160. Read from.

  Next, the control unit 110 supplies the data of each page of the file data read from the storage unit 160 to the thumbnail image generation unit 120, similarly to the display method 1 (step S302). The thumbnail image generation unit 120 generates thumbnail images 11 and 12 of each page based on the received data of each page, and supplies the thumbnail images 11 and 12 of each page to the display image generation unit 130 (step S303). Note that the thumbnail images 11 and 12 as images are the same as those in the display method 1, and the description thereof is omitted here.

  The display image generation unit 130 generates a plurality of image bundles in which the thumbnail images 11 of the respective pages supplied from the thumbnail image generation unit 120 are arranged so as to be arranged in the first direction (step S304). The thumbnail images 11 of the respective pages may be arranged from the left to the right of the display area in ascending order of page numbers such as page 1, page 2, and page 3, or conversely, in descending order of page numbers. You may line up with. In this example, as shown in FIG. 7A, thumbnail bundles 21, 22, 23, and 24 are illustrated as a plurality of image bundles arranged in ascending order of page numbers from the left to the right of the display area.

  Next, the display image generation unit 130 determines whether or not there is a selected page as a page selected and opened by the user (step S305). Then, when there is a selected page (step S305: Yes), the display image generation unit 130, like the thumbnail bundle 24 shown in FIG. 7A, is in the thumbnail bundle 24, and the thumbnail image 13 corresponding to the selected page. , 14 are deformed and generated as a display image in a spread state (step S306). Here, if there is no selected page (step S305: No), the display image generation unit 130 proceeds to step S307.

  Next, the display image generation unit 130 generates a display image in which the thumbnail bundles 21, 22, 23, 24 generated as a plurality of image bundles are arranged along the second direction intersecting the first direction ( Step S307). Here, the display image generation unit 130 arranges the plurality of deformed thumbnail images 11 so as to partially overlap the adjacent images, and arranges the images such that the distance between the images becomes narrower as the distance from the thumbnail image 11 of the cover page increases. Alternatively, the thumbnail bundle 21 is formed by arranging the images in parallel at a predetermined interval between the predetermined position and the last page. The other thumbnail bundles 22, 23, 24 are also composed of a plurality of similar thumbnail images 11.

  When there is a page selected and opened by the user or a selected page which is the last opened page, the display image generation unit 130 determines that the thumbnail bundle 24 is included in the thumbnail bundle 24 shown in FIG. 7A. , Thumbnail images 13 and 14 corresponding to the selected page are generated as spread display images. The display image generation unit 130 arranges the thumbnail image 13 that is the image of the selected page and the thumbnail image 14 that is the image of the page immediately after the selected page so that the entire page can be seen. Further, the display image generation unit 130 widens the interval between the image of the selected page and the images of the pages before and after the selected page, which form the spread state, so that the content of the image of the page represented by the data of the selected page can be viewed. .. With such a two-page spread display, the user can easily know the most recently read page by the two-page spread image arranged in the thumbnail bundle 24, in this example, the thumbnail images 13 and 14. You can

  Further, in step S307, the display image generation unit 130, similarly to the above-described display method 1, selects pages to be arranged side by side along the first direction of the thumbnail bundles 21, 22, 23, 24, or For example, representative thumbnail images 31, 32, 33, 34 which are display images of representative pages such as covers are generated. Since these display images are the same as those in the display method 1, the description thereof is omitted here.

  Note that, as shown in FIG. 7A, for example, the images of the thumbnail bundle 21 including the thumbnail image 11 located at the beginning of the thumbnail bundle 21 may be arranged so as to overlap the display of the representative thumbnail image 31. In other words, a part of the representative thumbnail image 31 related to the representative page of the files included in the thumbnail bundle 21 may be displayed on the background of the thumbnail bundle 21. Similarly, in the thumbnail bundles 22, 23, 24, the thumbnail image located at the beginning may be arranged so as to overlap the display of the representative thumbnail images 32, 33, 34.

  Note that the thumbnail bundle 21 and the representative thumbnail image 31 may overlap not only the thumbnail image 11 located at the beginning but also other thumbnail images (not numbered) arranged side by side with the thumbnail image 11. .. Further, the thumbnail bundle 21 may be displayed so that the thumbnail bundle 21 can be moved so that the overlapping degree is changed. The representative thumbnail image 31 may be displayed in the full width of the display unit 140 in the first direction (X axis), for example.

  With such a display, a part of the representative thumbnail images 31, 32, 33, 34 relating to the representative pages of the files included in the thumbnail bundles 21, 22, 23, 24 are thumbnail bundles 21, 22, 23, 24. Is displayed in the background. Therefore, the user visually recognizes the images related to the representative thumbnail images 31, 32, 33, and 34 displayed on the background of the thumbnail bundles 21, 22, 23, and 24 so that the thumbnail bundles 21, 22, 23, and 24 are displayed. You can easily know the contents of the included files.

  Then, the control unit 110 displays various display images generated by the display image generation unit 130 on the display unit 140 (step S308), and ends the series of processes. As described above, also in the display method 2 described above, the same effect as that of the display method 1 described above can be obtained.

  Note that, as shown in FIG. 7B, for example, in the thumbnail bundle 21, the thumbnail image 11f displayed overlapping the representative thumbnail image 31 of the representative page is moved to a position where it does not overlap, and is set as the moved thumbnail image 11m. Can be displayed. This movement can be performed by, for example, the user placing his or her finger 90f on the display portion of the thumbnail image 11f, which is a touch panel, and moving the finger 90m, such as dragging and dropping or flicking. Note that when the finger 90m moves away from the touch panel for a predetermined time, the thumbnail image 11m can be moved again as the thumbnail image 11f which is the display at the original position. By doing so, the user can easily read the representative thumbnail image 31 without being disturbed by the thumbnail images 11f displayed in an overlapping manner, and can know the content of the thumbnail bundle 21. it can.

  Further, as shown in FIG. 7C, for example, the thumbnail image 11s of the thumbnail bundle 21 can be moved to a position overlapping with the representative thumbnail image, and the thumbnail image in the spread state can be moved and displayed on the other thumbnail images 11p and 11r. it can. This movement is performed by a moving operation such as a drag and drop operation or a flick operation in which the user moves the finger 90f to the position of the finger 90m in the direction of the arrow in the figure with the finger 90f applied to the display portion of the thumbnail bundle 21 that is a touch panel. be able to. By doing so, the thumbnail bundle 21 is spread over a wide area and displayed, so that the user can easily read the thumbnail images included in the thumbnail bundle 21.

(Modification of Display Example 2)
Next, a modified example of the display example 2 will be described with reference to FIG. FIG. 8 is a diagram showing a modified example of the display example 2. In the display example 2 shown and described in FIG. 7A, for example, the file name n1 representing the content of the representative thumbnail image 31 of the representative page is arranged in a region below the central portion of the display image of the representative page such as a cover. It was displayed. In comparison with this, the modification shown in FIG. 8 is different in the arrangement position of the file name n5 representing the content of the representative thumbnail image 31. In the modified example shown in FIG. 8, the file name n5 representing the content of the representative thumbnail image 31 is displayed so as to be superimposed on the central portion of the display image of the representative page. The file name n5 can be restated as the document name. Thus, for example, by displaying the file name n5 over the central portion of the display image of the representative page such as the cover, the user can easily know the contents of the files included in the thumbnail bundle 21.

[Display method 3]
(Display example 3)
Next, the display method 3 in the display device 100 will be described with reference to FIGS. 9 and 10. FIG. 9 is a flowchart for explaining the thumbnail image display method 3, and shows the flow of processing executed by the display device 100. FIG. 10 is a diagram showing a display example 3 of thumbnail bundles including thumbnail images. In addition, also in the description of the display example 3, the same components as those described above will be denoted by the same reference numerals as those of the display device 100.

  As shown in FIGS. 9 and 10, first, the control unit 110, similar to the display method 1, displays thumbnail bundles displayed as a search screen from a plurality of book data and electronic photo files stored in the storage unit 160. File data corresponding to, for example, the thumbnail images 11, 12, 15, 16, 17 and the like, which form the 21, 26, 27, 29 and the thumbnail bundles 21, 26, 27, 29, are read (step S401).

  Next, the control unit 110 supplies the data of each page of the file data read from the storage unit 160 to the thumbnail image generation unit 120, similarly to the display method 1 (step S402). The thumbnail image generation unit 120 generates thumbnail images 11, 12, 15, 16, 17, etc. of each page based on the received data of each page, and supplies the thumbnail images 11, 12, 15, 16, 17 and the like to the display image generation unit 130 (step S403). The thumbnail images 11, 12, 15, 16, 17 and the like as images are the same as those in the display method 1, and therefore the description thereof is omitted here.

  Although not shown in FIG. 10, the display image generation unit 130 arranges the thumbnail images 11, 12, 15, 16, 17, etc. of the respective pages supplied from the thumbnail image generation unit 120 in the first direction. A plurality of image bundles arranged in (1) are generated (step S404). At this time, the display image generating unit 130, as the image bundle corresponding to one file data, the temporary thumbnail bundle including the thumbnail bundles 25, 26, 27 and the thumbnail image 11 at the beginning, and the image corresponding to the second file data. As a bundle, a temporary thumbnail bundle including the thumbnail bundle 29 and the thumbnail image 17 at the head is generated.

  Next, with respect to the display of each temporary thumbnail bundle generated as one image bundle and two image bundles, the control unit 110 has an instruction to display a section for each document or a page number designation (image number designation). It is determined whether or not (step S405).

  In step S405, if the control unit 110 determines that there is an instruction to display the documents for each document, or that the number of pages or the number of images is specified (step S405: Yes), the control unit 110 includes, for example, one row of thumbnail bundles. The display image generation unit 130 is instructed to change the arrangement of the thumbnail bundle such as changing the number of thumbnail images to be displayed (step S406), and the process proceeds to the next step S407. In this example, when there is a page number designation such as the number of pages included in one thumbnail bundle or the upper limit of the number of images is set, the thumbnail image 11 is set at the beginning, and the thumbnail image 12, The provisional thumbnail bundle including 15 and 16 corresponds to one file including more pages than the designated number of pages. That is, this provisional thumbnail bundle becomes a target for which the arrangement of thumbnail bundles is changed in step S407.

  If the control unit 110 determines in step S405 that there is no instruction to display the classification of each document or the number of pages is not specified (step S405: No), the process proceeds to the next step S407.

  In step S407, when there is a change in the arrangement of thumbnail bundles such as the number of thumbnail images included in one row of thumbnail bundles, the display image generation unit 130 sets the temporary thumbnail bundle having the thumbnail image 11 at the beginning as a plurality of thumbnail bundles, In this example, the display image is generated by being divided into three thumbnail bundles 25, 26, and 27. The display image generation unit 130 sorts the thumbnail images 11 and 12 up to the upper limit number into the thumbnail bundle 25, and sorts the thumbnail images 15 exceeding the upper limit number into the thumbnail bundle 26 located next to the thumbnail bundle 25 in the second direction. Further, the thumbnail images 16 exceeding the upper limit number are distributed to the thumbnail bundle 27 located next to the thumbnail bundle 26 in the second direction to generate three thumbnail bundles 25, 26, 27. The thumbnail images 11, 15, 16 of the respective pages may be arranged in the ascending order of page numbers from the left to the right of the display area, or may be arranged in descending order of page numbers.

  In this way, the thumbnail images 11, 12, 15, 16 and the like included in one file are divided by the upper limit number and displayed as a plurality of thumbnail bundles assigned to the three thumbnail bundles 25, 26, 27. By doing so, for example, it is possible to prevent a problem in which the number of thumbnail images 11, 12, 15, 16 included in one thumbnail bundle 25 is too large and the user cannot recognize the images.

  The display image generating unit 130 includes the thumbnail bundles 25, 26, and 27, and a representative thumbnail image 38 as a display image of a selected page of a file configured with the thumbnail image 11 at the beginning or a representative page such as a cover. To generate. The display image generation unit 130 arranges the representative thumbnail images 38 side by side along the first direction of the thumbnail bundle 25.

  In addition, a title n8 indicating the content of the corresponding document is additionally displayed on the thumbnail bundle 25 indicating the beginning of the three thumbnail bundles 25, 26, and 27 as a plurality of thumbnail bundles divided according to the upper limit number. It may be that. The title n8 is arranged so as to overlap a part of the representative thumbnail images 38 arranged side by side along the first direction of the thumbnail bundle 25. In this way, by additionally displaying the title n8 indicating the content of the corresponding document, the content of the document included in the thumbnail bundle 25 can be easily known.

  Further, when there is no change in the arrangement as described above in step S407, the display image generation unit 130, as in the above-described display method 1, the display image generation unit 130 creates an image bundle corresponding to the second file data. , A thumbnail bundle 29 having the top as the thumbnail image 17 and arranged in a line is generated. Then, the display image generation unit 130 generates a representative thumbnail image 39 that is a display image of the selected page of this file, a representative page, a cover, or the like, and arranges the thumbnail bundle 29 side by side along the first direction. Deploy. Further, similarly, the display image generation unit 130 may additionally display the title n9 indicating the content of the corresponding document on the thumbnail bundle 29. Note that the title n9 is arranged so as to overlap a part of the representative thumbnail images 39 arranged side by side along the first direction of the thumbnail bundle 29.

  Then, the control unit 110 displays various display images generated by the display image generation unit 130 on the display unit 140 (step S408), and ends the series of processes. As described above, also in the display method 3 described above, the same effect as that of the display method 1 described above can be obtained.

(Display example 4)
Next, with reference to FIG. 11, a display example 4 of a thumbnail bundle including thumbnail images will be described. FIG. 11 is a diagram showing a display example 4 of thumbnail bundles including thumbnail images.

  A display example 4 shown in FIG. 11 shows a display example in the case where the control unit 110 determines in step S405 of the above-described display method 3 that there is an instruction to display the documents separately (step S405: Yes). .. Note that in this example, the temporary thumbnail bundle including the thumbnail bundles 25, 26, and 27 generated as one image bundle, which is generated as one image bundle and has the head as the thumbnail image 11, is instructed to be displayed separately for each document. It corresponds to a certain file.

  In the display example 4, the temporary thumbnail bundle having the thumbnail image 11 at the head is divided into a plurality of thumbnail bundles, and in this example, three thumbnail bundles 25, 26, and 27 are displayed. At this time, the images included in the file are divided into the three thumbnail bundles 25, 26, and 27 according to each document, and are assigned as thumbnail images 11, 12, 15, 16 and the like for each document. Specifically, as the three thumbnail bundles 25, 26, and 27 corresponding to the document, the thumbnail bundle 25 having the thumbnail image 11 at the beginning, the thumbnail bundle 26 having the thumbnail image 15 at the beginning, and the thumbnail image 16 having the beginning at the thumbnail image 16 The bundle 27 is displayed.

  In this way, the thumbnail images 11, 12, 15, 16 and the like included in the file are divided according to the document and are displayed as a plurality of thumbnail bundles assigned to the three thumbnail bundles 25, 26, 27. As a result, the user can easily know the contents of the thumbnail bundles 25, 26, and 27, and can easily search for images.

  Note that each of the thumbnail bundles 25, 26, and 27 that stores the thumbnail images 11, 12, 15, and 16 of the divided documents is additionally displayed with titles 41, 42, and 43 indicating the content of the corresponding document. It may be that. In this example, date information in which the image data of this page is stored, for example, the date of taking an electronic photograph is additionally displayed as titles 41, 42, and 43. In this way, by additionally displaying the titles 41, 42, and 43 indicating the content of the corresponding document, the content of the document included in each of the thumbnail bundles 25, 26, and 27 can be easily known.

  In addition, thumbnail bundles 25, 26, and 27 are formed in the background portion located along the arrangement direction of the thumbnail bundles 25, 26, and 27 on the upper side in the first direction in this example. A representative page of a file including 12, 15, 16 or the like, or a representative thumbnail image 35 indicating a selected page is displayed as an enlarged image such as the thumbnail images 11, 12, 15, 16 for easy viewing. That is, the representative thumbnail image 35 may be displayed using the full width of the display unit 140 in the first direction (X axis). The representative thumbnail image 35, which is the display image of the representative page of the file or the selected page, is the same as that of the display method 1, and therefore the description thereof is omitted here.

  Further, the three thumbnail bundles 25, 26, and 27 as a plurality of thumbnail bundles divided according to documents may be arranged in descending order or ascending order according to the number of pages forming each thumbnail bundle. The number of pages forming each of the three thumbnail bundles 25, 26, and 27 can be rephrased as the number of thumbnail images 11, 12, 15, 16, and the like. By doing so, the user can easily know the number of pages included in the thumbnail bundles 25, 26, and 27. Further, the user can easily compare the number of pages included in the plurality of thumbnail bundles 25, 26, 27.
