Description

  The present invention relates to a content display device for displaying book-type digital content.

JP 2005-204338 A

  In recent years, there are many small devices such as mobile phones having a display. Furthermore, there are already many digital contents provided in the form displayed on the display, which are used by many users. Some of these contents provide books provided on paper as digital contents. For example, Patent Document 1 discloses a technique for displaying a manga as digital content on a screen.

  However, in such a small device, naturally the display size must be reduced, and the screen cannot be displayed in the same size as a book provided on paper. For this reason, naturally, it is necessary to reduce the display content. However, if the entire spread page of the book is reduced and displayed, characters and images become too small to read. In particular, the screen of a mobile phone or the like is an extremely small screen, and if a spread page screen is displayed on the screen, it is impossible to read characters.

  On the other hand, there may be a display method such as disassembling the display contents and displaying each enlarged image. However, since the display by this method no longer has the form of a book, it is far from the consciousness of reading a book. For users who are accustomed to books, it is difficult to understand how to handle digital content that is far from the books.

  An object of the present invention is to provide a digital content display device that can read a book-type digital content having a spread page in a form that is easy to read even on a small screen and that is similar to a book provided on paper. Is to provide.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, a digital content display device of the present invention provides:
A book type digital content having a plurality of spread pages consisting of a first spread page and a second page is displayed on the screen, and the screen display is to be viewed among the first and second spread pages. A digital content display device in which only one browsing page is displayed in its entirety and the other page is not displayed in its entirety,
An adjacent page switching operation means for performing an adjacent page switching operation for displaying an adjacent page of the current browsing page as a new browsing page;
When the adjacent page switching operation is performed and the current browsing page is switched to the adjacent page of the browsing page, the screen display area that is the screen display target in the spread page is the spread page between the first page and the second page. From the first display area in which only the page on the browsing page before switching is displayed as a whole and the other page is not displayed as a whole, only the other page is displayed as a whole and the page on the browsing page before switching is displayed as a whole. Page switching display means for scrolling and displaying the page image of the spread page in a form that is moved to the second display area that is not performed,
It is characterized by providing.

  According to the configuration of the present invention, since the entire one page of the first page and the second page of the spread page is displayed on the entire screen, the display content is compared with the case where the entire spread page is displayed on the screen. Easy to see. In addition, when an adjacent page switching operation is performed, scroll display is performed on the other side of the spread page, so that the user can recognize the page movement and proceed to read the page in the same style as when reading a book on paper. I can go.

  Further, the adjacent page switching operation of the present invention may include a page turning operation for switching the browsing page to a back page that forms the back side of the browsing page. In this case, when the page turning operation is performed, the page switching display means can be configured to display at least a part of the page turning operation process of the browse page in the screen display area moved by scroll display. . According to the present invention, the page movement within the same spread page can be performed by a simple scroll display in which the screen display area is moved from right to left or from left to right. Furthermore, when turning the page and displaying the back page, the screen display area is scrolled as described above, and the operation of turning the page is displayed in the screen display area during the scroll movement. The user can recognize that the page has been turned, and can continue to read the page in the same style as when reading a book on paper.

  The page switching display means of the present invention animately displays a page turning operation for turning a browse page to be turned when the page turning operation is performed, and scrolls the spread page area. In this, at least a part of the page turning operation expressed by the animation is included and can be configured to be displayed on the screen. Since the page turning operation can be recognized more realistically by the animation display, it becomes easier to read the page in the same style as when reading a book on paper.

  This page-turning animation is based on the page-turning action of the viewing page that is the target of page turning. It can be expressed in the form of appearing sequentially according to. Specifically, in the process of page turning, the first page and second page of the spread pages that are to be browsed next are areas that do not overlap with the page being turned, as the page turning action proceeds. The animation will be displayed sequentially. Thereby, in the process of the page turning operation, the next facing pages appear sequentially as necessary, so that the page turning operation can be expressed more realistically.

  It is also possible to determine the same number of frames for the animation of the page turning operation and the number of frames used for the scroll display. According to this configuration, the sense of unity of scroll movement and animation display is increased, and smooth expression is possible.

  Further, the page switching display means of the present invention can display the movement of the screen display area by scroll display and the page turning operation that is displayed in an interlocking manner. That is, according to this configuration, the sense of unity of scroll movement and animation display is increased, and the page turning operation can be expressed more realistically in the screen display area where scroll movement is performed. For example, the page switching display means can be configured to display so that a page expressed in a form that is turned in an animation of a page turning operation is always included in the screen display area. As a result, the page turning operation can be recognized more clearly, and it can be surely understood that the page has been turned. Furthermore, the page switching display means is configured such that the movement of the screen display area by the scroll display moves to the second display position in a form that precedes the page that moves in the form of turning in the animation of the page turning operation. Can do. As a result, the destination page can be quickly viewed.

  By the way, the page switching display means of the present invention performs the page turning operation, and when the scrolling display is executed in the form of displaying the page turning operation of the browse page as an animation, the page turning operation and the page switching direction coincide with each other. When the adjacent page switching operation is newly performed, an animation of the page turning operation of the browse page is continuously displayed, while the scroll direction of the scroll display is switched to the opposite direction. it can. When a page turning operation is performed, a page turning operation and scroll display are required to view the back page of the current browsing page. However, if a page switching operation is performed in the same page switching direction as the previous page turning operation in the middle of the page turning operation and scroll display, the page on the reverse side of the above-mentioned reverse page is viewed. It becomes. For this reason, although the page turning operation needs to be continued as it is, the scroll display that moves the screen display area to the second display position needs to be returned to the original first display position again. Therefore, when this additional page switching operation is performed, even if the screen display area has not reached the second display position, the scroll direction is reversed when the operation is performed, and the screen display area is By moving to the first display position, the page can be moved quickly. This is especially effective when you want to turn pages one after another in the same direction, and when you turn a single page, you can only move pages one page at a time compared to moving the screen display area to the opposite side. Speed will be much faster.

  Moreover, in this invention, it can comprise, and an enlarged display means to carry out enlarged display of the browsing page displayed on the whole screen by the browsing page display means. Further, in this case, it is possible to provide an enlarged display area moving means for moving the display area displayed on the screen in the enlarged display state of the browsing page.

  Further, when the enlarged display means is provided, the page switching display means, when the adjacent page switching operation is performed in the enlarged display state of the browse page, when the current browse page is switched to the adjacent page of the browse page, The scroll page (the screen display area is displayed first) after the browse page in the enlarged display state is reduced so that at least the entire browse page is displayed (for example, after returning to the normal display before enlargement) (Moving from the area to the second display area) can also be started. At this time, after moving to the second display area, the same area as the enlarged area in the screen display area enlarged immediately before may be enlarged. In the enlarged display state of the browse page, a display restriction unit that prohibits page switching to a different page from the spread page including the browse page that is enlarged may be provided.

  The digital content display device of the present invention can be a portable display device that can be carried by a user. Further, the screen can be a vertically long screen having a longer vertical width than a horizontal width. The method of viewing a spread page as in the present invention is effective for a display device having a small screen, and is particularly effective for a vertically long screen having no width for displaying both pages of the spread. This makes it possible to browse the book-type digital content on a portable device that can only be mounted with a small display.

  Further, the digital content display device of the present invention can be a mobile phone, whereby the book-type digital content can be browsed by the mobile phone.

  Furthermore, the present invention may be software (program) that causes a computer to execute the above-described means.

  The storage unit 13 stores and holds content data for displaying the digital content in the present embodiment on the screen and an application that allows the display unit 11 to display the digital content on the basis of the content data. Yes. The content data may be received from an external server through communication by the wireless unit 14, or may be stored in the storage unit via a storage medium. It may be stored in a connected storage medium.

  In the present embodiment, the digital content displayed on the screen of the display unit 11 includes a plurality of spread pages 20 including a first spread page 20A and a second page 20B as shown in the upper diagram of FIG. It is premised on the book type digital content, and is displayed on the screen by executing the application. The display form is determined as follows.

  That is, the display of the book-type digital content in the present embodiment is such that only the browsing page that is the browsing target among the first page 20A and the second page 20B of the spread page is displayed as a whole, and the other page is not displayed as a whole. The screen display is assumed. In other words, in the display state for page browsing, it is assumed that the entire spread page 20 is not displayed and only one page of the spread is displayed as a whole.

  FIG. 4 is a diagram for explaining a display form of digital contents in the present embodiment. Note that, here, the display state of the pages denoted by reference numerals 21b and 22a is illustrated as the spread page 20, but the display of other pages is the same as this.

  On the page image (image data) of the spread page 20, the browse page to be browsed of the first page 20A and the second page 20B of the spread page is entirely displayed on the screen, and the other page is displayed on the screen. The screen display area 11B displayed on the screen is set so that it is not displayed on the entire screen, and only the image (image data) included in the screen display area 11B among the page images (image data) of the spread page 20 is displayed on the screen 11A. Is displayed. FIG. 4 is a visual representation of this, and a spread page area 11D is set in which a plurality of spread pages 20 are drawn in such a manner that they are switched in the same area. On the spread page area 11D, the spread page 20 having the browse page to be viewed on either the first page 20A or the second page 20B of the spread page is drawn, and a screen is displayed on the spread page area 11D. As the screen display area 11B to be displayed, an area is set in which the browsing page is entirely displayed on the screen and the other page is not entirely displayed. Then, the page image of the spread page 20 in the screen display area 11B set in this way is displayed on the screen 11A of the display unit 11.

  As shown in FIG. 4A, the screen display area 11B displays only the right page 20B as a whole and does not display the left page 20A as a whole. Only the page 20A is displayed as a whole, and the page is set to one of the left page display areas where the right page 20B is not displayed as a whole. In the present embodiment, both the right page display area and the left page display area have a predetermined setting position on the spread page 20 to be displayed, and are set to the same area on each spread page. In addition, both of the right page display area and the left page display area in the present embodiment are not only the browse page on the spread page 20, but also a part of the reverse page (the browse page on the reverse page). (Part of the side) is also displayed.

  The spread pages 20 of the present embodiment are the left and right spread pages, but may be upper and lower spread pages or other pages. The digital content of the present embodiment is configured to have a plurality of pages with consecutive page numbers. That is, each page has a configuration identified by a page number assigned with a serial number. If the page is a spread page 20, page numbers that are continuous on both the first page 20A and the second page 20B are displayed. It is numbered. The page image data for screen display is stored in the storage unit 13 as separate image data in a form in which both spread pages are associated with each other.

  Here, the browsing page display processing will be specifically described with reference to FIG.

  First, in order to browse the book type digital content of the present embodiment, the CPU activates a corresponding application. Accordingly, in S1, the CPU displays a page (initial page) predetermined for initial display in the content. Specifically, the page number of the initial page is stored in the storage unit 13 in advance, whereby the initial page is specified as the browsing page, and the spread page including this is specified. Then, screen display based on the image data of the specified spread page is performed. However, in the image data of the spread page, the screen display area 11B is set so that the entire initial page specified as the browse page is displayed, and only the area 11B is displayed on the screen (view page). Display means). Here, it is assumed that the top page or cover of the book type digital content is defined as the initial page. Moreover, the page displayed when it was closed last time may be stored in the storage unit 13, and based on this, this page may be displayed as the initial page. However, in the case of a single-sided page such as a cover page, only the single-sided page is displayed as a whole.

  In S2, the CPU determines whether or not there is a page movement operation. Various operations can be set for the page movement operation. In the present embodiment, an adjacent page switching operation for displaying an adjacent page of the current browsing page as a new browsing page is possible. Here, the numeric keypad “4” is defined as a one-page return operation unit, and “6” is defined as a page feed operation unit, and these constitute a page switching operation unit (adjacent page switching operation means). That is, in the adjacent page switching operation unit of the present embodiment, the numeric keypad corresponding to the page turning direction (here, the left-right direction) is selected, and a correspondence relationship is provided between the operation unit and the displayed page turning operation. .

  It should be noted that other page movement operations such as an operation of inputting a page number directly from the numeric keypad and moving to the page of the input page number, or an operation of jumping to the first page or the last page may be possible. If a page movement operation has been performed, the process proceeds to S3, and if not, the process proceeds to S8.

  In S3, based on the page moving operation, the CPU specifies the page designated to be displayed next as the next browsing page, and further specifies the spread page including the page. Here, as the page movement operation is performed, the CPU specifies the page number of the page to be the next browsing page, and further specifies the spread page including the page of the page number based on the specified page number. To do.

  In subsequent S4, the CPU determines whether or not page turning is required when switching the display from the current browsing page to the next browsing page. Here, it is determined whether the spread page before the page movement operation and the spread page including the page to be the next browsing page specified by the page movement operation are the same spread page. If they are the same, it is determined that page turning is necessary and the process proceeds to S5. If it is determined that they are different, it is determined that page turning is not necessary and the process proceeds to S9.

  In S5, page image data of the newly specified spread page (respective page image data of both spread pages) is read.

  In S <b> 6, the CPU specifies the page turning direction, and causes the display unit 11 to perform animation display of the page turning operation in the specified direction. Further, the CPU specifies which page is the current browsing page, and simultaneously with the animation display, the CPU 11 displays the screen display area 11B set on the spread page data on the display unit 11 at the same time. From the first display area where the entire browsing page is displayed ((a) of FIG. 8 and FIG. 9), the page moves to the opposite side of the spread with respect to the browsing page, and the reverse page area is entirely Scroll display to move to the second display position to be displayed ((e) to (g) in FIGS. 8 and 9) is performed. In other words, the animation of the page turning operation is performed on the data using the current spread page and the next spread page, while the scrolling image display area 11B is specified on the animation image data in each frame of the animation. Then, only the animation image in the area 11B is displayed on the screen 11A (page switching display means).

  It is determined whether the animation of the page turning operation performed in S6 is a right page turning or a left page turning, and then an animation display corresponding to the determined page turning direction is performed. These page-turning animations have frames drawn so that the inclination angle of the page changes in accordance with the direction in which the page is turned, and these frames are defined corresponding to the page turning. It is implemented in the form of displaying sequentially at regular time intervals according to the order.

  In this embodiment, as shown in FIGS. 8 and 9, the page (22 or 21) of the page (22a or 21b) turned in each frame of the page turning motion animation is a perspective view. Inclined expression in the form. Here, the paper surface (22 or 21) having the page to be turned (22a or 21b) has its left and right end edges extending in the vertical direction while maintaining a straight line parallel to the vertically extending spread boundary line 20S. It changes so as to draw a curved locus in which the corners of the upper and lower ends of the edge are convex upward.

  Further, the animation of the page turning operation has at least one frame from the state in which the spread page including the current viewing page is flatly displayed until the next spread page is flatly displayed. Here, there are 9 to 10 frames (however, in the drawing, some frames are omitted). As shown in FIGS. 8 and 9, each frame has the same inclination angle of the straight line indicating the upper and lower edges of the paper (22 or 21) having the pages (22a or 21b) to be turned in the order of reproduction. It is drawn in a form that changes sequentially with each angle.

  Further, in the present embodiment, the page (22 or 21) to be turned is not only the shape thereof, but also the display content in the page (22 or 21) is inclined in each frame of the page turning motion animation. Inclination is expressed in a form that reflects. As shown in FIGS. 8 and 9, the page (22 or 21) of the page (22a or 21b) turned in each frame has a first page length direction (here, the extending direction of the left and right edges of the page). A plane coordinate system is set with the axis and the second axis in the page width direction (here, the extension direction of the upper and lower edges of the page: which inclines as the page is turned). When the page image of the browse page (22a or 21b) is turned and tilted, the plane coordinate system in each tilted state is set, and the browse page (22a or 21b) that was in the flat display state at the beginning of page turning. A page image reflecting the tilt state at that time is drawn on the page (22a or 21b) in a tilted manner in such a manner that the page image is subjected to coordinate transformation. However, after the page (22 or 21) of the page to be turned (22a or 21b) crosses the spread boundary, the page (22a or 21b) as the page image (22 or 21) of the page to be turned (22a or 21b). The page image of the back page (the page to be set next as the browsing page: 22b or 21a) is displayed. For the page image of the back page (22b or 21a), the page image of the back page (22b or 21a) displayed in the flat display state at the end of the page turning is coordinate-transformed into the plane coordinate system in the inclined state at that time. As a page image reflecting the tilt state at that time, the page image is tilted and drawn on the page (22b or 21a).

  In the page turning animation in S6, the displayed content is displayed in an inclined state on the inclined surface (22 or 21) in each frame to be displayed. However, the displayed content on such a paper surface (22 or 21) is displayed. For example, the inclined paper surface (22 or 21) may be displayed as a page turning operation (for example, a page turning operation of a blank page) in which only the paper frame is displayed. . Furthermore, during the page turning operation, the current next spread page and the display contents of the next spread page are not displayed at all, and at least only the paper frame is displayed (for example, a blank page). May be. These can greatly simplify the process. In this case, S5 and S6 may be switched in order. In this embodiment, in order to display the page image reflecting the tilted state, in S5, the page image data of the next spread page is read in advance, and in S6, the page image data of the current spread page and S5 The page turning animation is displayed using the page image data of the next spread page read out in step (1).

  Further, as shown in FIGS. 8 and 9, as the page turning operation is started, a partial area of the spread page (25 or 26) including the page set as the next browsing page (22b or 21a) is displayed. Appear. That is, as the page to be turned (22a, 21b) is displayed in a perspective view, the page on the opposite side to the back page (22b, 21a) in the spread page (25, 26) including the back page (22b, 21a). (23a, 24b) is the same display state as the flat display state before the page (22a, 21b) to be turned (however, the area that does not overlap the paper surface (22, 21) of the page (22a, 21b) to be turned) Appears at (). Then, as the page turning operation proceeds, the appearance area increases. When the page (22a, 21b) to be turned exceeds the spread boundary ((e) to (g) in FIGS. 8 and 9), the back page ( The pages (23a, 24b) on the opposite side of the spread with respect to 22b, 21a) are always displayed. On the other hand, when the page to be turned (22a, 21b) exceeds the spread boundary, a part of the page (21b, 22a) on the opposite side to the page to be turned (22a, 21b) is turned (22a, 21b). The page image of the back page (22b, 21a) is displayed on the page (22, 21) of the page (22a, 21b) that is hidden by being overlapped with the page (22, 21) of the page. When the page (22a, 21b) to be turned reaches the end position ((g) in FIGS. 8 and 9), the page (21b, 22a) on the opposite side of the spread is the page of the page (22a, 21b) to be completely turned. 22, 21), and the entire back page (22 b, 21 a) is displayed in a flat display state.

  However, the animation of the page turning operation as described above is displayed on the screen 11A of the display unit 11 only in the area that is included in the moving screen display area 11B. The entire paper surface (22, 21) of the page (22a, 21b) to be turned may not always be displayed.

  In the scroll display by moving the screen display area 11B performed in S6, the image display area 11B set on the page image data of the spread page 20 is displayed on the first page of the spread page 20 as the browse page before the page movement operation. Whether the page is the page 20A or the second page 20B is specified, and scroll display toward the page on the opposite side is performed. In the present embodiment, as shown in FIGS. 8 and 9, the scroll display start position (first display position: FIGS. 8A and 9A) and end position (second display position: FIG. 8). (G) and FIG. 9 (g)) are determined in advance, and since the scroll movement locus is also set in advance, the image display area 11B is moved according to these settings. In the present embodiment, during the movement of the image display area 11B, the page that is currently being page-turned represented by the animation moves so as to enter the image display area 11B. .

  8 and 9, the scroll movement trajectory here is the scroll display start position (first display position: left page display area in the case of FIG. 4 (a), FIG. 4 (b)). The right page display area) to the end position (second display position: right page display area in FIG. 4A, left page display area in FIG. 4B) is linearly determined. A simple scrolling display has been implemented. Furthermore, the image display area 11B of the present embodiment is not set so that all the pages (22a, 21b) to be turned are necessarily included, and is turned depending on the inclined state of the pages (22a, 21b) to be turned. It is determined that a part of the pages (22a, 21b) protrudes from the area. In the case of FIG. 8 and FIG. 9, the browsing page (22a, 21b) in the browsing display state (flat display state) is displayed at the center of the image display area 11B with a slight margin area around it. The page turning animation of the pages (22a, 21b) to be turned is displayed in the blank area, and the screen drawing process is simplified.

  Also, in this scroll display, similarly to the animation of the page turning operation, a plurality of frames whose order is determined in accordance with the scroll direction are sequentially displayed at regular time intervals according to the order. Here, the position of the image display area 11B corresponding to each frame is set at regular intervals between the scroll display start position (first display position) and end position (second display position). Here, the number of frames of the page turning motion animation and the number of frames used for the scroll display are determined to be the same.

  Note that, in the present embodiment, the screen display is configured in such a manner that the movement of the screen display area 11B by scroll display and the page turning operation displayed in animation are interlocked. Specifically, as shown in FIGS. 8 and 9, the movement of the screen display area 11 </ b> B by scroll display includes at least a part of the pages (22 a, 21 b) that are surely turned at the destination. Is set to More specifically, the movement of the screen display area 11B by scroll display precedes the movement of the page (22a, 21b) expressed in the form of turning in the animation of the page turning operation, and the end position (second display position). ) To move towards. 8 and 9, the screen display area 11B has already reached the end position (second display position) at the stage (e) in the figure, which is in the middle of turning pages, and the movement has been completed.

  On the other hand, if it is determined in S4 that there is no page turning, the process proceeds to S9. In S <b> 9, the CPU displays the screen display area 11 </ b> B set on the spread page data with respect to the display unit 11 from the first display area where the current browsing page is entirely displayed, on the reverse side of the spread with respect to the browsing page. Scroll to the second display position where the entire page area on the opposite side is displayed (page switching display means). However, in S9, the animation of the page turning operation as in S6 is not performed, and the image display area 11B is displayed on the current viewing page (20) on the current spread page (20) as shown in FIGS. 22a, 21b) only moves to the page (21b, 22a) on the opposite side of the spread page (22a, 21b). That is, the page turning operation does not occur, and the processing is simply to move the viewpoint to the page on the opposite side of the spread.

  When the page switching process performed in S6 and S9 ends, the process proceeds to S7. In S7, based on the data read in S5, the CPU displays the next browsing page on the opposite side of the page. That is, the screen display area 11B is positioned at the end position (second display position) in the scroll display of S6 and S9, and only the next browsing page is displayed in the screen display area 11B, and the other of the spread pages. The page is displayed in such a way that the entire page is not displayed. If a page switching operation to an adjacent page is newly performed thereafter, the current position of the screen display area 11B is set as a new scroll display start position (first display position).

  In S8, it is determined whether or not an operation for ending the browsing of the book-type digital content of the present embodiment has been performed. In the present embodiment, it is assumed that browsing is ended by an operation on the ON / OFF button 15a provided on the upper right of the numeric keypad. If there is no browsing end operation, the process returns to S2, and if there is a browsing end operation, this process ends.

  Further, the digital content of the present embodiment has a page enlargement function as shown in FIG.

  FIG. 16 shows an example of the page enlargement process, which will be described below.

  In S50, the CPU determines whether or not there is an enlargement operation. The presence / absence of an enlargement operation in the present embodiment is determined based on the presence / absence of an operation to “5” of the numeric keypad input unit 15T that constitutes the enlargement operation unit. If there is an enlargement operation, enlargement display is performed in S51, and if there is no enlargement operation, this processing is terminated. In the present embodiment, the central portion of the browsing page is set as the initial position of the enlarged display.

  In S52, it is determined whether or not there is an operation for moving the enlarged display position. The operation of moving the enlarged display position is an operation of scrolling the enlarged display area 11C on the enlarged display image data, and the page image included in the enlarged display area 11C is displayed on the screen 11A. In the present embodiment, “4”, “6”, “2”, and “8” of the numeric keypad input unit 15T are defined as operation units for moving the enlarged display area 11C. Determine whether or not there is an operation. If there is no operation for moving the enlarged display position, the process proceeds to S55. If there is an operation for moving the enlarged display position, in S53, the enlarged display area 11C is scrolled in the direction corresponding to the operation, and the screen is moved. The enlarged position displayed on 11A moves.

  However, in subsequent S54, it is determined whether or not the enlarged display area 11C scrolled on the enlarged display image data has reached a predetermined movement limit position. When the movement limit position has not been reached, the scroll display based on the operation is continued, and when the movement limit position has been reached, the scrolling is immediately stopped and the movement of the enlarged display area 11C beyond that is prohibited.

  Note that the movement limit position may be defined as a page frame of the spread page 20 and prohibited from being enlarged in a region other than the spread page, but in the present embodiment, the first page 20A and the second page of the spread page 20 are the same. It is defined as a page frame of a page set as a browsing page in the page 20B. That is, as shown in FIG. 18, the upper end edge 20P2, the lower end edge 20P3, the left and right end edges 20P1, and the spread boundary 20S of the viewing page are determined as the movement limit positions, and the enlarged display area 11C is movable within these. Has been.

  In S55, the CPU determines whether or not an enlargement display cancellation operation has been performed. The presence / absence of the enlargement display canceling operation in the present embodiment is determined based on the presence / absence of an operation to “0” of the numeric keypad input unit 15T constituting the enlargement canceling operation unit. If there is an operation for canceling the enlarged display, the currently displayed enlarged display is canceled and this processing is terminated. If there is no operation for canceling the enlarged display, the process returns to S52. This process is repeatedly performed at a predetermined cycle.

  As mentioned above, although one Embodiment of this invention was described, these are only illustrations to the last, and this invention is not limited to these, A various change is possible unless it deviates from the meaning of a claim. is there.

  In the above embodiment, with respect to the page switching processing shown in S2 to S7 and S9 in FIG. 5, when a page switching operation (adjacent page switching operation in the above embodiment) is performed, scroll display or animation display in S6 and S9 is performed. Unless completed, the next page switching operation cannot be started.

  However, when the adjacent page switching operation is continuously performed, the scroll display starts after the screen display area 11B starts from the start position (first display position) to the end position (second display position), and then finally. May return to the start position (first display position) again. In this case, the scroll display time can be shortened by performing a process of turning the scroll direction in the reverse direction. If the adjacent page switching operation is a page turning operation with an animation of a page turning operation, only the screen display area 11B to be scrolled is moved in the reverse direction while the animation display is continued. According to this configuration, if the page to be turned at least exceeds the spread boundary line 20S, the page designated as the next browsing page can be browsed in a flat display state by two consecutive adjacent page switching operations.

  The above processing can be realized by performing the processing of FIG. 10 on the processing of S2 to S7 and S9 of FIG.

  First, in S10, it is determined whether or not there is an adjacent page switching operation. If there is an adjacent page switching operation, the process proceeds to S11, and a new browsing page and a spread page including it are specified. In subsequent S12, it is determined whether or not page turning occurs in the adjacent page switching operation in S10. If there is page turning, the process proceeds to S16, and if there is no page turning, the process proceeds to S13. These are the same processes as S2 to S4.

  In S13, scrolling of the screen display area 11B is started. This is the same processing as S9 of the above embodiment. However, when an adjacent page switching operation is performed in the direction opposite to the adjacent page switching operation performed in S10 during scrolling of the screen display area 11B (S14: Yes), the screen display is performed when the operation is performed. The scroll direction of the area 11B is switched to the reverse direction (S15), and the image display area 11B is moved toward the original scroll start position. That is, when the adjacent page switching operation in the reverse direction is performed during the scroll movement of the screen display region 11B starting from FIG. 6A and FIG. 7A, the screen display region 11B is started from the stage where the operation is performed. Scroll movement to return to (a) of FIGS. 6 and 7 starts.

  In S16, the page image data of the newly specified spread page (respective page image data of both spread pages) is read, and in S17, animation of the screen display area 11B scrolling and page turning operation is started. These are the same processes as S5 and S6 in the above embodiment. However, when an adjacent page switching operation is performed in the same direction as the adjacent page switching operation performed in S10 during the scrolling and page turning animation of the screen display area 11B (S18: Yes), as shown in FIG. When the operation is performed, the scroll direction of the screen display area 11B is switched to the opposite direction, and the image display area 11B is moved toward the original scroll start position (S20). However, the page turning animation continues. On the other hand, when the adjacent page switching operation is performed in the opposite direction to the adjacent page switching operation performed in S10 during the scrolling and page turning animation of the screen display area 11B (S19: Yes), as shown in FIG. When the operation is performed, the scroll direction of the screen display area 11B is switched to the reverse direction, and the image display area 11B is returned to the original scroll start position (S21). At this time, the current page turning animation is continued in a form that is changed to an animation that reverses the frame when the operation is performed (S21).

  If it is determined in S22 that the on-screen display area 11B scrolling and page turning animation has been completed, the process ends. 11 and 14 show only page switching in one direction, but the same processing is naturally performed in page switching in the reverse direction.

  In addition, the above-described process of FIG. 10 allows the adjacent page switching operation to be continued up to two, and does not support further continuous operations. FIG. 12 shows a process corresponding to a further continuous operation of the adjacent page switching operation.

  First, in S30, it is determined whether or not there is an adjacent page switching operation. If there is an adjacent page switching operation, the process proceeds to S31, and a new browsing page and a spread page including it are specified. In S32, it is determined whether or not page turning occurs in the adjacent page switching operation in S30. If there is page turning, the process proceeds to S36, and if there is no page turning, the process proceeds to S33. These are the same processes as S2 to S4.

  In S33, it is determined whether or not the screen display area 11B is being scrolled. If not scrolling, scrolling is started in S34. If scrolling is in progress, scrolling is resumed after the scroll direction is reversed at this stage in S35.

  In S36, the page image data of the newly specified spread page (respective page image data of both spread pages) is read, and in subsequent S37, it is determined whether or not the page turning animation is being performed.

  If the page turning animation is being executed in S37, the process proceeds to S37. In S38, it is determined whether or not the adjacent page switching operation performed in S30 is a page moving operation in the same direction as the page turning direction of the latest page (the most recently turned page). If they are in the same direction (S38: Yes), that is, if the situation is as shown in FIG. 13B, the screen display area is displayed at this stage in S39 as shown in FIGS. 13C to 13G. While the scroll direction of 11B is reversed and switched to the reverse direction, a page turning operation for a new page is started in addition to the page turning operation currently being performed. That is, a page turning animation is performed in which page turning by a plurality of sheets of paper proceeds simultaneously with a time difference. Conversely, if it is determined in S38 that the adjacent page switching operation performed in S30 is a page moving operation in the direction opposite to the page turning direction of the latest page (the most recently turned page) ( S38: No) In S43, as shown in FIG. 14, the scroll direction of the screen display area 11B is reversed and switched to the reverse direction at this stage, and the latest page in the page turning animation being performed (most recently turned). The animation relating to the page is resumed in the form of reversing the frame from that stage.

  On the other hand, if the page turning animation is not being executed in S37, the process proceeds to S40. In S40, it is determined whether or not the screen display area 11B is being scrolled. If the screen display area 11B is not being scrolled, in S42, scrolling is started to spread the screen display area 11B and move it to the opposite side, and a new page turning animation for turning the page currently defined as the viewing page is started. To do. If the screen display area 11B is being scrolled, in S41, at this stage, the scroll direction of the screen display area 11B is reversed and switched to the reverse direction, and a new page that turns the page currently defined as the viewing page is turned. Start turning animation.

  In S44, it is determined whether or not the page turning animation and the screen display area 11B have been scrolled. If completed, this process is terminated, and if not completed, the process returns to S30. Note that the processing in FIG. 12 is repeatedly performed at predetermined intervals.

  By the way, the book-type digital content in the present invention can be a novel or a catalog, but as shown in FIG. 15, it is determined by both pages (21b ′, 22a ′) of the spread page (20 ′). It may be a cartoon in which a picture and dialogue are drawn in the frame 20k. Rather than displaying an enlarged picture or line for each frame 20k, the display format in which the entire page is displayed as in the present invention is easier to read because the previous and subsequent stories can be grasped.

  Moreover, in the said embodiment, the browsing page displayed entirely in the screen 11A can be expanded and displayed. Further, the display area displayed on the screen can be moved in the enlarged display state of the browsing page. When such an enlarged display function is provided, when the adjacent page switching operation is performed in the enlarged display state (zoomed-in state) of the browse page, as shown in FIG. 19, the currently displayed browse page is the relevant browse page. When switching to the adjacent page, the display page in the enlarged display state is reduced (zoomed out) so that at least the entire page is displayed (for example, after returning to the normal display before enlargement), Scroll display (moving the screen display area from the first display area to the second display area) can also be started. At this time, as shown in FIG. 20, after moving to the second display area, the same area as the enlarged area in the screen display area that was enlarged immediately before may be enlarged (zoomed in). On the other hand, when such an enlarged display function is provided, in a magnified display state of the browse page, page switching to a page different from the spread page including the browse page being magnified may be prohibited.

  The page switching display as in the above embodiment is effective when displaying a book-type digital content having left and right facing pages when the display screen is a vertically long screen whose left and right width is shorter than the vertical width. is there. While general book-type content has many left and right spread types, general mobile phones have a vertically long form extending in the length direction from the handset to the handset, and the screen is similarly A vertically long screen having a vertical direction in the length direction is provided. For this reason, the left and right screen widths are narrow and it is difficult to display both spread pages simultaneously, but adopting the page switching display as in the above embodiment makes it easy to see the entire spread pages. . Conversely, when displaying book-type digital content having upper and lower facing pages, the page switching display of the present invention is effective when the horizontal width is a horizontally long screen longer than the vertical width. For example, it can be applied to a mobile phone having means for switching the screen orientation.
