Description

  The present invention relates to a display device having a function of browsing electronic books.

From the latter half of 1990, electronic books, which were only ideas until then, have been put into practical use, and now, electronic books are becoming more popular in the world as dedicated terminals are released. Initially, content was provided only by text files, but now comics, magazines, photo collections, etc. are also sold, and serial comics are also digitized (see, for example, Patent Document 1). .
Japanese Patent Laid-Open No. 7-230473

  Series comics occupy several to tens of pages in magazines that are published regularly, and many of them have the feature that the story gradually develops for each story in the magazine. Due to the nature of such serialized comics, there are many cases where the first page and the first frame are made the same as or almost the same as the last page and the last frame in order to adjust the previous review and the flow of the story.

  It is necessary to review and adjust the flow of the story when serializing comics in magazines, but if you view serials together like a book, duplication will occur and wasteful browsing will occur for viewers In addition, it makes the distance between the stories conscious and cuts off the flow of the story.

  In addition, in the case of electronic comics obtained by capturing serialized comics with a scanner, there are cases in which extra pages are created between stories, similar to paper-based books. In an electronic comic that browses comics page by page, this extra page interrupts the flow of the story and makes the viewer bothersome.

  In addition, although the problem was demonstrated about the serialized comics of digitization, the same problem can be assumed also about the electronic book of other serialized things.

  The present invention has been proposed in view of the above-described conventional problems, and the object of the present invention is to eliminate browsing of unnecessary displays such as overlapping pages and extra pages when browsing electronic books. It is to provide a display device.

In one embodiment of the present invention, there is a display device having a function of continuously browsing an electronic book of serialized articles in units of stories over a plurality of stories, and means for detecting a break of a story from electronic book data; Means for acquiring a first image of the last page or last frame of the previous story in the detected segment; means for acquiring a second image of the first page or first frame of the subsequent story in the detected segment; The means for determining the identity between the first image and the second image, and when it is determined that the first image and the second image are identical, either the first image or the second image And a means for setting it to non-display during a browsing operation of browsing either one page at a time or one frame at a time .

  Preferably, the process of setting the image to non-display is collectively performed before the start of browsing the electronic book.

  Preferably, the process of setting the image to non-display is performed at the time of reaching the break of the story when browsing the electronic book.

  In the display device of the present invention, when browsing electronic books, it is possible to eliminate browsing of wasteful displays such as overlapping pages and extra pages, and to perform seamless browsing without interrupting the flow of talk Can do.

  Hereinafter, preferred embodiments of the present invention will be described.

<Operation>
FIG. 5 is a flowchart showing a processing example in which overlapping page or frame non-display processing is performed collectively before browsing. That is, when the browsing application is activated and the electronic book is opened, all overlaps between the stories are checked and the display is omitted.

  In FIG. 5, when the user starts browsing the electronic book by performing a predetermined operation with the operation unit 12 (step S <b> 101), the control unit 11 activates a browsing application by the browsing application program 142 in the storage unit 14 ( Step S102).

  Next, the user selects an electronic book to be read by the operation unit 12, and the control unit 11 opens the electronic book (step S103).

  Next, the control unit 11 sets “1” to the variable N (step S104), and acquires the image data A of the last page (or frame) of the Nth episode (step S105). That is, in the case of the data structure of FIG. 2 or FIG. 4, the page having the last page flag “#” in the page number is specified on the lower page by specifying the story number of the image management table as N. A number is specified, and image data is acquired from the corresponding image. In the case of the data structure of FIG. 3, the story number of the story data is identified as N, and the page number is identified by identifying the page number having the last page flag “#” from the image management table. Image data is acquired from the corresponding image. The same process is performed when frame image data is acquired.

  Next, the control unit 11 acquires the image data B of the first page (or frame) of the (N + 1) th episode (step S106). That is, in the case of the data structure of FIG. 2 or FIG. 4, by specifying the story number of the image management table of N + 1 and specifying the page number with the first page flag “$” in the lower page. A page number is specified, and image data is acquired from the corresponding image. In the case of the data structure of FIG. 3, the page number is specified by specifying that the story number of the story data is N + 1, and specifying the page number having the first page flag “$” from the image management table. The image data is acquired from the corresponding image. The same process is performed when frame image data is acquired.

  Next, the control unit 11 causes the image comparison unit 15 to compare the image data A and the image data B, and determines whether or not the similarity condition is satisfied (step S107). A known technique such as image matching can be used for the image comparison.

  Here, when the image data A and the image data B satisfy the similarity condition (YES in step S107), either the image data A or the image data B is set to non-display (step S108). Which of the similar image data A and image data B is hidden may be fixedly determined (for example, a later story is not displayed) or may be determined in advance by user settings. The non-display setting is performed by setting a skip flag to the corresponding page number in the image management table (FIGS. 2 to 4). The same operation is performed when a frame is set to non-display.

  When the image data A and the image data B do not satisfy the similarity condition (NO in step S107), the non-display process (step S108) is not performed.

  Next, the control unit 11 adds “1” to the variable N (step S109), and determines whether or not the Nth episode is the final episode (step S110). In the case of the data structure of FIG. 2 or FIG. 4, this determination is made based on whether or not the final story flag “★” is present in the story number of the image management table. In the case of the data structure of FIG. Judgment is made based on whether or not there is a final story flag.

  If the Nth episode is not the final episode (NO in step S110), the process proceeds to image data acquisition (step S105) and the same processing is repeated. If the Nth episode is the final episode (YES in step S110), a skip flag is set on all overlapping pages (or frames) between the episodes, and browsing by the user is started (step). S111).

  When browsing by the user, the control unit 11 that operates based on the browsing application program 142 determines whether or not the skip flag is set in the corresponding page number (or frame) of the image management table (FIGS. 2 to 4). The page (or frame) with the skip flag set is not displayed. Thereby, the continuity of browsing can be ensured.

  FIG. 6 is a flowchart illustrating a processing example in which the process of hiding overlapping pages or frames is performed during browsing. That is, when the last page (or the last frame) of the main story is reached while browsing the electronic book, it is compared with the first page (or the first frame) of the next story as needed, and display is omitted if necessary. It is a thing.

  In FIG. 6, when a user starts a browsing process of an electronic book by performing a predetermined operation with the operation unit 12 (step S <b> 121), the control unit 11 activates a browsing application by the browsing application program 142 of the storage unit 14 ( Step S122).

  Next, the user selects an electronic book to be read by the operation unit 12, and the control unit 11 opens the electronic book (step S123). Then, the user starts browsing the electronic book (step S124). In this state, the first page (or frame) of the electronic book is displayed.

  Next, the control unit 11 determines whether or not the main story is the final story (step S125). In the case of the data structure of FIG. 2 or FIG. 4, this determination is made based on whether or not the final talk flag “★” is included in the story number of the image management table. In the case of the data structure of FIG. Judgment is made based on whether or not there is a final story flag.

  If the main story is the final story (YES in step S125), the control unit 11 advances the display to the next page (or frame) (step S126). This is because there is no need to consider the overlap of pages (or frames) in the last story.

  When the main story is not the final story (NO in step S125), the control unit 11 determines whether or not the current page (or frame) is the final story (step S127). This determination is made based on whether or not the last page flag “#” (or the last frame flag) is set in the page number of the image management table (FIGS. 2 to 4).

  Here, when the current page (or frame) is not the last of the main story (NO in step S127), the control unit 11 advances the display to the next page (or frame) (step S126).

  When the current page (or frame) is the last of the main story (YES in step S127), the control unit 11 acquires the image data A of the last page (or frame) of the main story (step S128). That is, the page number corresponding to the current page is specified from the image management table (FIGS. 2 to 4), and image data is acquired from the corresponding image. The same process is performed when frame image data is acquired.

  Next, the control unit 11 acquires the image data B of the first page (or frame) of the next story (step S129). That is, in the case of the data structure of FIG. 2 or FIG. 4, the story number in the image management table is specified by adding “1” to the main story, and the first page flag “$” is added to the page number on the lower page. A page number is specified by specifying a certain thing, and image data is acquired from the corresponding image. In the case of the data structure of FIG. 3, the story number of the story data obtained by adding “1” to the main story is specified, and the page number having the first page flag “$” is specified from the image management table. Thus, the page number is specified, and the image data is acquired from the corresponding image. The same process is performed when frame image data is acquired.

  Next, the control unit 11 causes the image comparison unit 15 to compare the image data A and the image data B, and determines whether or not the similarity condition is satisfied (step S130). A known technique such as image matching can be used for the image comparison.

  Here, when the image data A and the image data B satisfy the similarity condition (YES in step S130), either the image data A or the image data B is set to non-display (step S131). Which of the similar image data A and image data B is hidden may be fixedly determined (for example, a later story is not displayed) or may be determined in advance by user settings. The non-display setting is performed by setting a skip flag to the corresponding page number in the image management table (FIGS. 2 to 4). The same operation is performed when a frame is set to non-display.

  When the image data A and the image data B do not satisfy the similarity condition (NO in step S130), the non-display process (step S131) is not performed.

  Next, the control unit 11 advances the display to the next page (or frame) (step S126), but since the skip flag is set, the display is further advanced to the next page (or frame). Thereby, the continuity of browsing can be ensured. These processes are repeated until browsing is completed.

  FIG. 7 is a flowchart showing a processing example in which the processing of hiding extra pages is performed in a batch before browsing.

  In FIG. 7, when the user starts a process of browsing an electronic book by performing a predetermined operation using the operation unit 12 (step S <b> 201), the control unit 11 activates a browsing application by the browsing application program 142 in the storage unit 14 ( Step S202).

  Next, the user selects an electronic book to be read by the operation unit 12, and the control unit 11 opens the electronic book (step S203).

  Next, the control unit 11 sets “1” to the variable N (step S204), detects the first page of the N + 1 episode, and acquires the image data of the previous page (step S205). That is, in the case of the data structure of FIG. 2 or FIG. 4, by specifying the story number of the image management table of N + 1 and specifying the page number with the first page flag “$” in the lower page. The page number is specified, and the previous page number is specified (if there is no previous page in the story, the last page number of the previous story), and image data is acquired from the corresponding image. In the case of the data structure of FIG. 3, the story number of the story data is identified as N + 1, the one with the first page flag “$” in the page number is identified from the image management table, and the previous page number is further identified. (If there is no previous page in the story, the page number of the last page of the previous story) is specified, and image data is acquired from the corresponding image. In the case where the first page flag does not exist, for example, there is a method of regarding the page with the title of the story as the first page.

  Next, the control unit 11 determines whether or not the acquired page is an extra page (step S206). For example, there is a technique in which a page is drawn and the drawing is a regular page if the drawing covers a wide range of the page, and the other is regarded as an extra page.

  If the page is not an extra page (NO in step S206), the control unit 11 adds “1” to the variable N (step S207), and proceeds to acquisition of image data (step S205).

  If it is an extra page (YES in step S206), the control unit 11 sets the extra page to be non-display (step S208). This is done by setting a skip flag to the corresponding page number in the image management table (FIGS. 2 to 4).

  Next, the control unit 11 determines whether or not the Nth episode is the final episode (step S209). In the case of the data structure of FIG. 2 or FIG. 4, this determination is made based on whether or not the final story flag “★” is present in the story number of the image management table. In the case of the data structure of FIG. Judgment is made based on whether or not there is a final story flag.

  If the Nth episode is not the final episode (NO in step S209), the control unit 11 adds “1” to the variable N (step S207), and the process proceeds to acquisition of image data (step S205).

  When the Nth episode is the final episode (YES in step S209), a skip flag is set in all the extra pages between the episodes, and browsing by the user is started (step S210).

  When browsing by the user, the control unit 11 operating based on the browsing application program 142 determines whether or not a skip flag is set for the corresponding page number in the image management table (FIGS. 2 to 4), and the skip flag is set. The added page is not displayed. Thereby, the continuity of browsing can be ensured.

  FIG. 8 is a flowchart showing a processing example in which the process of hiding extra pages is performed during browsing.

  In FIG. 8, when the user starts browsing the electronic book by performing a predetermined operation with the operation unit 12 (step S <b> 221), the control unit 11 activates a browsing application by the browsing application program 142 in the storage unit 14 ( Step S222).

  Next, the user selects an electronic book to be read by the operation unit 12, and the control unit 11 opens the electronic book (step S223). Then, the user starts browsing the electronic book (step S224). In this state, the first page of the electronic book is displayed.

  Next, the control unit 11 determines whether or not the main story is the final story (step S225). In the case of the data structure of FIG. 2 or FIG. 4, this determination is made based on whether or not the final talk flag “★” is included in the story number of the image management table. In the case of the data structure of FIG. Judgment is made based on whether or not there is a final story flag.

  If the main story is the final story (YES in step S225), the control unit 11 advances the display to the next page (step S226).

  When the main story is not the final story (NO in step S225), the control unit 11 determines whether or not the current page is a page immediately before the last page of the main story (step S227). This determination is performed by specifying the page number next to the current page number in the image management table (FIGS. 2 to 4) and determining whether or not the last page flag “#” is set for the page number.

  If the current page is not the previous page of the last page of the main story (NO in step S227), the control unit 11 advances the display to the next page (step S226).

  When the current page is the previous page of the last page of the main story (YES in step S227), the control unit 11 acquires the last page of the main story and the image data of the next page (step S228). That is, the image data is acquired from the corresponding image of the page number corresponding to the last page from the image management table (FIGS. 2 to 4), the next page number is specified, and the image data is acquired from the corresponding image To do.

  Next, the control unit 11 determines whether any of the acquired pages is an extra page (step S229). For example, there is a technique in which a page is drawn and the drawing is a regular page if the drawing covers a wide range of the page, and the other is regarded as an extra page.

  If none of the pages is an extra page (NO in step S229), the control unit 11 advances the display to the next page (step S226).

  If any one is an extra page (YES in step S229), the control unit 11 sets the corresponding extra page to be non-displayed (step S230). This is done by setting a skip flag to the corresponding page number in the image management table (FIGS. 2 to 4).

  Next, the control unit 11 advances the display to the next page (step S226). If the skip flag is set for the page, the display is further advanced to the next page. Thereby, an extra page is abbreviate | omitted and the continuity of browsing can be ensured. These processes are repeated until browsing is completed.
