Abstract

PROBLEM TO BE SOLVED: To sequentially efficiently display one or a plurality of columns and segments cut out from one page in contents including a plurality of pages without generating a blank.SOLUTION: A content display device determines whether or not a blank occurs on a screen of a display unit when allowing the display unit to display a first display portion cut out from a page to be displayed, and when determining that the blank occurs, cuts out a second display portion to be sequentially displayed from a next page, and combines the first display portion and the second display portion to allow the display unit to display the combined display portion. Accordingly, the device allows the display unit to sequentially cut out and display contents so as to generate no blank or minimize the blank in the display unit.

Description

  The present invention relates to a content display apparatus, method, and program, and more particularly to a technique for efficiently displaying an image such as comic content.

  Conventionally, image data (content) for browsing comic images is distributed via a network or made available via a portable recording medium (memory card), and various types of mobile phones, portable game machines, etc. Technologies that enable browsing with electronic devices are known.

  The content to be browsed described in Patent Document 1 includes one or a plurality of image data units for each page and anchor description data in which a plurality of transition sequences of image area extraction reference coordinates (anchor coordinates) are described. The browsing device sequentially determines image region extraction reference coordinates based on a transition sequence of one designated image region extraction reference coordinate, and the image included in the extraction frame defined by the sequentially determined image region extraction reference coordinates Are sequentially restored from the image data included in one or a plurality of image data units, and at least a part of the restored image is displayed on the display means.

  The electronic filing device described in Patent Document 2 combines and extracts necessary parts from the front page and the back page when registering a document that makes one meaning on both sides (a document on both sides). In addition, the synthesized image is registered in an enlarged / reduced manner so as to fit the designated document size.

JP 2011-33850 A JP 7-311831 A

  The transition sequence of the image region extraction reference coordinates (anchor coordinates) described in Patent Document 1 is described for each page, and Patent Document 1 does not describe anchor coordinates extending over two pages. That is, the image browsing apparatus described in Patent Document 1 cannot browse a comic image that spans two pages.

  The electronic filing device described in Patent Document 2 combines images cut out from two pages, a front page and a back page, so that operations such as page turning can be omitted even in a document on both sides. It does not cut out a part sequentially according to the reading order and display it in an enlarged manner.

  By the way, when a comic image is electronically distributed, the screen size of the display device is small in the entire comic page, which may be difficult to read. In this case, a part of the entire page is cut out, and the display part is optimized and displayed in an enlarged size as compared with the case of the entire display. At this time, since the sizes of the steps and frames vary, the size is determined to be optimal for the size of the display device each time and displayed.

  In this process, if the frame at the last stage of the page is cut out, a blank space (no display portion) may occur in the displayable area of the display device, and it takes time to display data, and the user In addition, the number of display instructions for transitioning the screen is increased, resulting in trouble and waste. In particular, in a tablet display device, when a comic is displayed, if it is cut out and displayed for each stage, a non-display portion may occur greatly.

  The present invention has been made in view of such circumstances, so that margins do not occur when content consisting of images of a plurality of pages is cut out and sequentially displayed by cutting out one or more stages and frames in one page. Another object of the present invention is to provide a content display device, method, and program that can be efficiently displayed so that margins are reduced.

  In order to achieve the above object, a content display device according to an aspect of the present invention is content composed of images of a plurality of pages, has a divided region indicating a plurality of stages or frames in one page, and each Content acquisition means for acquiring content including position information of divided areas, display means having a screen size smaller than the image size of an image of one page of the content, and from the content acquired by the content acquisition means, the display means Display control means for sequentially cutting out portions suitable for the screen size and displaying them sequentially on the display means, wherein the display control means is cut out based on position information of a plurality of divided areas in the display target page. Occurs on the screen of the display means when only the first display portion corresponding to one or more divided areas is displayed on the display means. The first display portion should be cut out and displayed on the display means or the first display portion should be cut out in accordance with the size of the margin to be displayed, and the next page of the display target page should be sequentially displayed. A second display portion corresponding to one or more divided areas is cut out, and the cut out first display portion and the second display portion are combined and displayed on the display means.

  The aspect ratio of one page of the content does not necessarily match the aspect ratio of the display means, and the sizes of the steps and frames in one page are irregular. When a display portion (first display portion) corresponding to a divided area indicating a step or frame in one page suitable for the screen size of the display means is sequentially cut out and displayed on the display means, particularly at the end of the page When the display means displays only the first display portion from which the stage or frame is cut out, a margin is likely to occur on the screen of the display means. According to one aspect of the present invention, when a margin is generated on the screen of the display unit, the first unit is selected according to the size of the margin, for example, when there is no margin or when the margin is small. The display part is cut out and only the first display part is displayed on the display means. On the other hand, when the margin becomes large, the first display part is cut out and the next page of the display target page is sequentially displayed. A second display portion corresponding to one or more divided areas to be displayed is cut out, and the cut out first display portion and the second display portion are combined and displayed on the display means. . As a result, the contents can be sequentially cut out and displayed so that no margin is generated in the display means or the margin is reduced, and can be displayed efficiently.

  In the content display device according to another aspect of the present invention, the display control means determines whether or not a margin is generated on the screen of the display means when only the first display portion is displayed on the display means. If the margin determining means determines that no margin is generated, the first display portion is cut out and displayed on the display means, and the margin determining means generates a margin. When the judgment is made, the first display portion is cut out, and the second display portion corresponding to one or more divided regions to be sequentially displayed on the next page of the display target page is cut out and cut out. The first display portion and the second display portion are combined and displayed on the display means.

  In the content display device according to still another aspect of the present invention, the display control unit compares the margin with the second display portion when the margin determination unit determines that a margin is generated, and When the second display portion is less than the margin, it is preferable that the first display portion and the second display portion are combined and displayed on the display means. Thereby, it can be displayed so that the 2nd display part combined and displayed with the 1st display part may not be cut.

  In the content display device according to still another aspect of the present invention, the display control means includes magnification conversion means for changing the magnification of the cut out first display portion and second display portion, and the magnification conversion means. When the second display portion is larger than the margin, the first display portion and the second display portion are reduced at the same rate to fit on the screen of the display means, and the maximum magnification is obtained. It is preferable to change the magnification so that. As a result, even when the second display portion is cut off (when it protrudes from the margin), the second display portion can be displayed so as not to be cut off, and the magnification of the first display portion and the second display portion can be achieved. By making the same, it is possible to avoid a sense of incongruity.

  In the content display device according to still another aspect of the present invention, the display control means includes a first margin generated when only the first display portion is displayed on the display means, or the first display portion. When the first margin generated when the display unit is combined with the second display portion and displayed on the display means, and the magnification of the first display portion and the second display portion is changed by the magnification conversion means And when the first margin is less than or equal to the second margin, the first display portion before the magnification change, or the first display portion and the second margin are compared with each other. When the first margin is larger than the second margin, the first display portion and the second display portion after the magnification change are combined and displayed on the display means. Is preferably displayed on the display means.

  The aspect ratio of the image obtained by combining the first display portion and the second display portion does not necessarily match the aspect ratio of the screen of the display means. Accordingly, when the first display portion and the second display portion are combined with the margin (first margin) generated before the reduction, the reduction is performed so as to fill the first margin. A margin (second margin) is generated in a direction different from the first margin. For example, when the first margin is in the vertical direction of the screen, if the composite of the first display portion and the second display portion is reduced, the second margin is generated in the horizontal direction of the screen. According to still another aspect of the present invention, when the first margin is larger than the second margin, the composite image after the magnification change is displayed, but the second margin is greater than or equal to the first margin. In such a case, the second display portion is not synthesized, or the second display portion is synthesized within a range where the first margin is generated, and the first margin is maintained.

  In still another aspect of the present invention, in the content display device, the display control unit includes a magnification conversion unit that changes a magnification of the cut-out second display portion, and the magnification conversion unit includes the second display unit. When the portion is larger than the margin, it is preferable that the magnification is changed so that the second display portion is reduced to fit in the margin and has the maximum magnification.

  According to still another aspect of the present invention, the magnification is changed (reduced) so that only the second display portion fits in the margin and becomes the maximum magnification. Thereby, the first display portion can always be displayed at the maximum magnification.

  In the content display device according to still another aspect of the present invention, the display control means has a predetermined ratio of a magnification ratio between the first display portion and the second display portion after the magnification is changed by the magnification conversion means. It is preferable to determine whether or not the value is within a value, and when the magnification ratio exceeds the specified value, it is preferable to prohibit display of the second display portion in the margin. When only the second display portion is reduced, the magnification ratio between the first display portion and the second display portion is different. When this magnification ratio exceeds a predetermined specified value, a sense of incongruity occurs. Although inconveniences such as difficulty in seeing characters occur, the above-mentioned problem is prevented from occurring by limiting the magnification ratio within a specified value.

  In the content display device according to still another aspect of the present invention, a first display mode for displaying the entire display target page and a portion suitable for the screen size of the display means are sequentially cut out from the entire display target page. Display mode setting means for setting the first display mode or the second display mode, and a display for instructing the next display or the previous display. Instructing means, and when the display mode setting means sets the first display mode and the display instruction means instructs the next display or the previous display, the display control means The entire previous page is displayed on the display means, the second display mode is set by the display mode setting means, and the next display or the previous display is instructed by the display instruction means. When, be displayed on the display means by cutting out a portion corresponding to the next divided area or before the divided regions of a page of the display object is preferably based on the position information in the page of the display object.

  In the content display device according to still another aspect of the present invention, the display device includes a vertical / horizontal detection unit that detects a vertical position or a horizontal position of the display unit, and the display mode setting unit is configured to detect the vertical position of the display unit by the vertical / horizontal detection unit. It is preferable that the first display mode is set when detected, and the second display mode is set when the lateral position of the display means is detected. Normally, since the entire page is vertically long, the first display mode is set to display the entire page when the display unit is in the vertical position, and the divided area in the page is displayed when the display unit is in the horizontal position. It is preferable to set the second display mode in which corresponding portions are cut out and sequentially displayed.

  A content display method according to still another aspect of the present invention is content composed of images of a plurality of pages, has a divided area indicating a plurality of stages or frames in one page, and obtains position information of each divided area. A content acquisition step for acquiring the content to be included, and a display unit having a screen size smaller than the image size of the image of the one page, and a portion suitable for the screen size of the display unit from the display target pages of the content A display control step of sequentially cutting out and displaying the display means, wherein the display control step cuts out the first display portion according to the size of a margin generated on the screen of the display means. Or the first display portion is cut out and the first page corresponding to one or more divided areas to be sequentially displayed on the next page of the display target page is displayed. Cut out display portion, by synthesizing the first display part and second display part cut out so that is displayed on the display means.

  The invention according to still another aspect of the present invention is a content composed of images of a plurality of pages, a content having a divided area indicating a plurality of stages or frames in one page, and including position information of each divided area And a display unit having a screen size smaller than the image size of an image of one page of the content, and a portion suitable for the screen size of the display unit from among the display target pages of the content A content display program that realizes a display control function that sequentially cuts out and displays sequentially by a computer, wherein the display control function is cut out based on position information of a plurality of divided regions in the display target page 1 Or, when only the first display portion corresponding to two or more divided areas is displayed on the display means, the screen is displayed on the display means. Depending on the size of the margin to be cut out, the first display portion should be cut out and displayed on the display means, or the first display portion should be cut out and the next page of the display target page should be sequentially displayed. A second display portion corresponding to one or more divided areas is cut out, and the cut out first display portion and the second display portion are combined and displayed on the display means.

  Embodiments of a content display device, method, and program according to the present invention will be described below with reference to the accompanying drawings.

<Configuration of content display device>
FIG. 1 is a block diagram showing an embodiment of a content display apparatus according to the present invention. In this embodiment, a tablet terminal 10 is shown.

  As shown in FIG. 1, the tablet terminal 10 mainly includes a communication unit 11, a processing unit 12, a display unit 13, an input unit 14, a display control unit 15, a ROM 16, a cache memory 17, and a vertical / horizontal detection unit 18.

  The communication unit 11 communicates with a server (for example, a content providing server) on the Internet via a mobile communication network.

  The processing unit 12 is a part that performs overall control of the entire tablet terminal 10 in accordance with a predetermined control program based on an operation instruction input from the input unit 14, and may be a CPU or the like.

  The display unit 13 is composed of a color liquid crystal display, and is used as a user interface for performing various setting operations and also as a display for displaying characters, images, figures, and the like.

  The input unit 14 is configured by a touch panel disposed on the upper surface of the display unit 13, or is configured by a touch panel and soft buttons on the screen of the display unit 13, and relates to various displays and operations according to the operation of the touch panel. This is the part for inputting instructions. The input unit 14 may be composed of a mechanical numeric keypad other than the touch panel, a multi-function cross key, or the like, or may be a combination of both.

  The display control unit 15 is a part that generates display information to be displayed on the display unit 13. Details of the display control unit 15 will be described later.

  The ROM 16 stores a control program for operating the tablet terminal 10, a content display program according to the present invention, imaged electronic comics, contents such as documents, and the like. The processing unit 12 and the display control unit 15 Performs a required calculation according to a control program or a content display program. Note that the ROM 16 can be constituted by, for example, a flash ROM.

  The cache memory 17 is used as a calculation work area by the processing unit 12 and the display control unit 15 and a temporary storage area for images displayed on the display unit 13 of the tablet terminal 10, and is configured by, for example, a volatile memory.

  The vertical / horizontal detection unit 18 detects a vertical position in which the rectangular display unit 13 is vertically long, or a horizontal position in which the rectangular display unit 13 is horizontally long. For example, the inclination (vertical position / horizontal position) of the tablet terminal 10 is measured by measuring gravitational acceleration. An angular velocity sensor that detects a position).

  However, as will be described later, whether to display the entire page to be displayed on the display unit 13 or to sequentially cut out and display a part suitable for the screen size of the display unit 13 from the entire page depends on the length of the original, the frame / column. Since it also depends on the orientation, the concept of the vertical position and the horizontal position does not depend on the length of the display unit 13, and in order to show for convenience that it will be changed depending on the orientation until it gets tired, An embodiment will be described in which the vertical position and the horizontal position are the horizontal positions.

<Content>
Next, content displayed by the content display device will be described.

  The content of this embodiment is an electronic comic, and is obtained by automatically analyzing a comic image using high-resolution image data (comic image) obtained by reading a paper-based comic page by page with a scanner and an authoring tool (not shown). It consists of additional information such as frame information and balloon information.

  The frame information includes position information of the frame area. The position information of the frame area is information indicating the frame area, and includes the number of frames included in the page, the coordinates of the vertex of each frame, and the shape of each frame. The position information of the frame area may be vector data indicating a frame boundary. The frame information further includes frame order information related to the frame order (playback order) of each frame.

  As shown in FIG. 2, one page of a comic is usually divided into three or four stages, and each stage is divided into one or more frames. The position information of the frame area can also serve as position information indicating the area of the stage, but may have position information for each stage separately.

  The comic image has an image size of, for example, 2000 × 1500 (dot), which is larger than the screen size of the display unit 13 of the tablet terminal 10 (for example, 1024 × 768 (dot)).

[Content display method]
Next, an embodiment of a content display method according to the present invention will be described.

  3 to 5 are flowcharts showing an embodiment of a content display method according to the present invention.

  It is assumed that the electronic comic is downloaded and stored in the ROM 16 of the tablet terminal 10 from the content providing server on the network via the communication unit 11. The electronic comic may be obtained through a portable recording medium (memory card).

  In FIG. 3, when displaying the electronic comic stored in the ROM 16, the vertical / horizontal detection unit 18 of the tablet terminal 10 detects whether the tablet terminal 10 is in the vertical position or the horizontal position, and displays based on the detection result. The mode is switched (step S10). That is, when the vertical / horizontal detection unit 18 detects that the tablet terminal 10 is in the vertical position, the first display mode is selected (step S12), and when the horizontal position is detected, the second display is performed. A mode is selected (step S14).

  When the first display mode is selected, display control is performed to display the entire comic image of one page on the entire screen of the tablet terminal 10 (step S16), and when the second display mode is selected, one page is displayed. A part of the comic images in the whole is cut out according to the reading order, and display control for sequentially displaying the comic images is performed (step S18).

  Then, it is determined whether or not there is a display end instruction input from the input unit 14 (step S19). If there is no display end instruction input (in the case of “No”), the process proceeds to step S10 to end the display. Is displayed (if “Yes”), the display is terminated.

<First display mode>
FIG. 4 is a flowchart showing details of the process in step S16 shown in FIG.

  In FIG. 4, in the first display mode, the processing unit 12 acquires a comic image for one page to be displayed as an electronic comic from the ROM 16, and passes the comic image to the display control unit 15 (step S20).

  The display control unit 15 reduces the comic image based on the size ratio between the image size of one page of the comic image and the screen size of the display unit 13, and causes the display unit 13 to display the reduced comic image (step S22). Thereby, the entire page is displayed on the entire screen of the display unit 13 (see FIG. 2A).

  Subsequently, the processing unit 12 determines whether or not there is a display instruction input for the next page from the input unit 14 (step S24). If there is a display instruction input (in the case of “Yes”), the processing unit 12 proceeds to step S20. . Thereby, the comic image of the next page is acquired.

  On the other hand, if there is no display instruction input (in the case of “No”), it is further determined whether or not the tablet terminal 10 is in the horizontal position (step S26), and if the tablet terminal 10 is in the vertical position (“No”). ), The process proceeds to step S22, and the current page is continuously displayed. In step S26, when it is detected that the tablet terminal 10 is in the horizontal position (in the case of “Yes”), the subroutine corresponding to the first display mode is ended.

<Second display mode>
First, an overview of the display method in the second display mode will be described.

  In the second display mode, when displaying a comic image with one page vertically long on the display unit 13 (that is, a horizontally long screen) when the tablet terminal 10 is in the horizontal position, one or more steps are cut out from the comic image. In this mode.

  As shown in FIG. 2, when the tablet terminal 10 displays a vertically long comic image (for example, a comic image with an aspect ratio of 4: 3) configured in one page in three rows on the display unit 13 in the horizontal position, The aspect ratio of the display portion corresponding to the two-stage area is close to the aspect ratio of the display unit 13 in the horizontal position.

  Therefore, by cutting out the display portion corresponding to the area of two steps from one page, and adjusting the magnification so that it fits on the screen of the display unit 13 in the horizontal position and the maximum magnification is displayed. The display portion cut out from the display target page (hereinafter referred to as the “first display portion”) is displayed as large as possible, and no margin is generated on the screen of the display unit 13 or the margin is minimized. (The upper part of FIG. 2B).

  Next, the first display portion corresponding to the remaining step (third step) area of one page is cut out, and the magnification is adjusted so as to fit in the horizontal display unit 13 and to the maximum magnification. As a result, a large margin is generated on the screen of the display unit 13.

  In the present invention, when such a large margin occurs, a display part cut out from the next page (hereinafter referred to as “second display part”) (in this example, the first stage (first stage) of the next page). The second display portion corresponding to the area (2) is added to the place where the margin is generated so that the margin is not generated as much as possible.

[First Embodiment]
FIG. 5 is a flowchart showing the first embodiment of the process of step S18 shown in FIG.

  In FIG. 5, in the second display mode, the processing unit 12 acquires from the ROM 16 position information indicating a comic image of a page to be displayed for an electronic comic and a frame or column area associated with the page. These pieces of information are passed to the display control unit 15. The display control unit 15 extracts the first display portion in the display target page to be displayed on the horizontal position display unit 13 based on the position information (step S30).

  The display control unit 15 determines whether or not a blank space is generated when only the extracted first display portion is displayed on the horizontal display unit 13 (step S32). The margin in this case is a screen generated when the first display portion is resized and displayed on the display unit 13 so that the horizontal size of the first display portion matches the horizontal size of the screen of the display unit 13. The bottom margin of If it is determined in step S32 that no margin is generated (in the case of “No”), the process proceeds to step S34, and only the first display portion is displayed on the display unit 13.

  On the other hand, when it is determined that a margin is generated (in the case of “Yes”), the processing unit 12 associates the comic image of the next page (next page) of the electronic comic display target page from the ROM 16 with this page. The position information indicating the frame or step area being acquired is acquired, and these pieces of information are passed to the display control unit 15. The display control unit 15 extracts the second display portion in the next page based on the position information (step S42).

  Subsequently, the image size of the image obtained by combining the first display portion of the display target page and the second display portion of the next page is compared with the screen size of the display unit 13 (step S42). In this case, the vertical size of the image obtained by resizing the first and second display portions so that the horizontal size of the combined image matches the horizontal size of the screen of the display unit 13 and the vertical size of the screen of the display unit 13 are set. Compare. When these sizes match, the process proceeds to step S45, and when the vertical size of the composite image is larger (when there is a protruding portion), the process proceeds to step S43. Further, when the vertical size of the composite image is smaller (when there is a margin), the process proceeds to step S40, where a second display area (next stage) larger than the currently extracted second display portion. The second display part including the above is extracted.

  In step S43, since a part of the composite image (second display part) protrudes from the margin, a display part other than the protruding second display part is output.

  For example, when the second display portion is inserted into the margin shown in FIG. 6A, as shown in FIG. 6B, if a protruding portion is generated, in step S43, display portions other than the protruding second display portion ( (Only the first display portion as shown in FIG. 6A) is displayed.

  On the other hand, if it is determined in step S42 that the first display portion and the second display portion match the screen size of the display unit 13, a composite image of the first display portion and the second display portion is output.

  That is, when the second display portion is inserted in the margin shown in FIG. 7A, as shown in FIG. 7B, if the margin and the protruding portion do not occur, step S42 proceeds to step S45. In step S45, a synthesized image obtained by synthesizing the first display portion and the second display portion is output as shown in FIG.

  Further, as a mode of outputting a composite image of the first display portion and the second display portion, a margin is generated when the second display portion for one stage is inserted in the margin shown in FIG. 7 (c)) When the second display portion for two levels is inserted, if an overhanging portion occurs, a display portion other than the second display portion of the second row protruding (ie, the first display portion and the second display portion). (Second display portion for one stage) is output. Thereby, a composite image as shown in FIG. 7C can be displayed.

  Subsequently, in step S34, during the display of only the first display part or the composite image obtained by synthesizing the first display part and the second part, the display control unit 15 instructs the next display instruction from the input unit 14. It is determined whether or not there is an input (step S36), and if there is a display instruction input (in the case of “Yes”), the process proceeds to step S30 to extract the latest first display portion in the next reading order. Make it.

  If there is a display instruction input during display of the composite image, the next page becomes the display target page. In this case, the first display portion may be extracted from the first stage of the display target page. You may make it extract a 1st display part from the stage next to the already displayed stage.

  If it is determined in step S36 that there is no next display instruction input from the input unit 14 (in the case of “No”), it is further determined whether or not the tablet terminal 10 is in the vertical position (step S38). When is in the horizontal position (in the case of “No”), the process proceeds to step S34, and the first display portion or the first and second display portions that are the current cutout region are continuously displayed. In step S38, when it is detected that the tablet terminal 10 is in the vertical position (in the case of “Yes”), the subroutine corresponding to the second display mode is ended.

  As described above, in the second display mode, not only the first display portion cut out from the display target page but also the second display area cut out from the next page is displayed in combination, so only the first display portion is displayed. It is possible to realize a display method that effectively uses a margin generated when displaying.

[Second Embodiment]
FIG. 8 is a flowchart showing a second embodiment of the process of step S18 shown in FIG. In addition, the same step number is attached | subjected to the part which is common in the flowchart of 1st Embodiment shown in FIG. 5, The detailed description is abbreviate | omitted.

  In the first embodiment, when the margin is smaller than the second display portion (when a part of the second display portion protrudes from the margin), only the first display portion is displayed without putting the second display portion in the margin. However, in the second embodiment, when the composite image is larger than the screen size (when the second display portion protrudes), the composite image is reduced so that the composite image falls within the screen size. Is different.

  That is, in step S42, the image size of the image obtained by combining the first display portion of the display target page and the second display portion of the next page is compared with the screen size of the display unit 13, and when these sizes match. The process proceeds to step S50, and when the vertical size of the composite image is larger (when there is a protruding portion), the process proceeds to step S44.

  In step S44, the display control unit 15 reduces the composite image so that the vertical size of the composite image of the first and second display portions matches the vertical size of the screen of the display unit 13 in the horizontal position.

  Subsequently, whether or not the margin (second margin) generated by reducing the composite image in step S44 is smaller than the margin (first margin) when it is determined that there is “margin” in step S42. Is determined (step S46).

  For example, if the second display portion is inserted in the margin (first margin) shown in FIG. 9A and the protruding portion is generated as shown in FIG. 9B, the protruding portion is not generated in step S44. In addition, the first display portion and the second display portion are reduced at the same rate. As a result of the reduction of the first display portion and the second display portion, margins (second margins) are generated on the left and right of the screen of the display unit 13 as shown in FIG. 9C.

  As shown in FIGS. 9A and 9C, when the second margin is smaller than the first margin (in the case of “Yes” in step S46), the process proceeds to step S48, where FIG. The first display portion and the second display portion as shown in c) are combined, and the combined image reduced at the same rate is output to the display unit 13 to display the combined image.

  On the other hand, if it is determined in step S46 that the second margin is larger than the first margin (in the case of “No”), the process proceeds to step S50.

  For example, the first display portion and the second display are inserted in the margin (first margin) shown in FIG. 10A so that the second display portion is inserted as shown in FIG. When the portion is reduced at the same rate, margins (second margins) are generated on the left and right sides of the screen of the display unit 13 as shown in FIG. In the example illustrated in FIG. 10, the total of the second margins generated on the left and right sides of the screen of the display unit 13 as illustrated in FIG. 10C is larger than the first margin illustrated in FIG.

  In this case, as shown in FIG. 10A, the first display portion that is not reduced is output to the display unit 13 to display the first display portion.

  If it is determined in step S42 that the first display portion and the second display portion match the screen size of the display unit 13, a composite image of the first display portion and the second display portion (a composite image that is not reduced). ) Is output. Further, as a mode of outputting a composite image that is not reduced, if the second display portion of the second page of the next page is inserted into the blank shown in FIG. 8A (first blank), the second row protrudes greatly. (FIG. 11 (b)) When the second display portion for one stage is inserted, there may be a case where no protruding portion is generated (FIG. 11 (c)). In this case, a composite image that is not reduced as shown in FIG.

  As described above, in the second display mode, not only the first display portion cut out from the display target page but also the second display area cut out from the next page is synthesized and displayed, and particularly in the second embodiment, the synthesis is performed. When a part of the image is larger than the screen size of the display unit 13, the entire composite image is reduced to fit the screen size, so that the margin generated when only the first display part is displayed is used effectively. Display method can be realized.

[Third Embodiment]
FIG. 12 is a flowchart showing a third embodiment of the process of step S18 shown in FIG. In addition, the same step number is attached | subjected to the part which is common in the flowchart of 2nd Embodiment shown in FIG. 8, The detailed description is abbreviate | omitted.

  The third embodiment is different from the second embodiment mainly in the method of reducing the composite image obtained by combining the first display portion and the second display portion. In the second embodiment, the first display portion and the second display portion are different. Although the display portion is reduced at the same rate, in the third embodiment, the first display portion and the second display portion are reduced at different magnifications.

  In step S42 of FIG. 12, when the image size of the composite image of the first and second display portions is compared with the screen size of the display unit 13, the vertical size of the composite image is larger (when there is a protruding portion). In step S60, the process proceeds to step S60.

  In step S60, the second display portion is cut out so that the second display portion cut out from the next page fits in the margin generated by causing the display unit 13 to display only the first display portion cut out from the display target page and has the maximum magnification. Reduce the display area only.

  FIG. 13A shows a state in which only the first display portion of the display target page is displayed on the display unit 13 and a margin is generated, and FIG. 13B shows the second page of the next page in the margin. This shows a case where a protruding portion is generated when a display portion is inserted.

  In this case, as shown in FIG. 13C, only the second display portion is reduced so that the second display portion of the next page fits in the margin and the maximum magnification is obtained.

  Next, a magnification ratio between the first display portion and the reduced second display portion is obtained, and it is determined whether or not the magnification ratio is within a predetermined specified value (step S62). The predetermined specified value may be 1.5, for example. It should be noted that if the magnification ratio of the first display portion and the second display portion is greatly different, a sense of incongruity may occur, and inconveniences such as difficulty in seeing characters in the second display portion may occur. By limiting the ratio, it is possible to prevent the above problem from occurring. The specified value may be appropriately set according to the screen size of the display unit 13 and the user's preference.

  If it is determined in step S62 that the magnification ratio between the first display portion and the reduced second display portion is within the specified value (in the case of “Yes”), the first display portion as shown in FIG. A combined image obtained by combining the reduced second display portion is output to the display unit 13 to display the combined image.

  On the other hand, if it is determined in step S62 that the magnification ratio between the first display portion and the reduced second display portion exceeds the specified value (in the case of “No”), the process proceeds to step S50.

  FIG. 14 shows a case where the magnification ratio between the first display portion and the reduced second display portion exceeds a specified value. As shown in FIG. 14 (a), the second display portion is inserted in the margin generated when only the first display portion is displayed, as shown in FIG. 14 (b), so that the protruding portion does not occur. If only the portion is reduced, the width of the second display portion becomes significantly smaller than the width of the second display portion as shown in FIG. 14C, and a sense of incongruity occurs, and characters appear on the second display portion. If there is, it becomes difficult to see the character.

  In this case, as shown in FIG. 14A, only the first display portion is output to the display unit 13 to display the first display portion.

  As described above, in the second display mode, not only the first display portion cut out from the display target page, but also the second display area cut out from the next page is combined and displayed, and particularly in the third embodiment, the combination is displayed. When a part of the image is larger than the screen size of the display unit 13, only the second display portion is reduced and put in the screen margin, so that the margin generated when only the first display portion is displayed is displayed. An effective display method can be realized.
