Description

  The present invention relates to an information display device, and more particularly to an information display device that displays image content in which one page is composed of a plurality of scene frames (frames).

Today, mobile terminals (for example, electronic book terminals and tablet terminals) that receive or store digitized information and allow a user to enlarge and view a necessary part of the received information are available. It's being used.
Since digitized information is generally managed and stored in units of pages, one entire page is displayed on the display screen.

When one page is composed of image content divided into a plurality of scene frames (hereinafter referred to as frames), for example, in the case of an electronic comic, for example, all frames included in the page are displayed on the display screen. The image of one frame is very small.
Therefore, if you want to check the details in one frame, you can perform a specific operation to enlarge the part of the image you want to check on the screen, or display the desired image part on the screen after the enlarged display. The display image is moved so as to be displayed inside.
That is, in order to sequentially confirm a plurality of frames included in one page, the user himself / herself repeatedly performs a display image enlargement operation, a reduction operation, and a movement operation as necessary.

  In particular, in the case of comics, the number of frames included in a page, their arrangement, and the size of each frame vary depending on the author's intention in consideration of the impression given to the reader and are usually not uniform. Therefore, in order for the user to display each frame sequentially in an appropriate size along the comic story, it is necessary to repeat the operations of enlargement, reduction, and movement appropriately. The burden is heavy.

In view of this, there has been proposed an apparatus capable of sequentially displaying image content including a plurality of frames on one page.
For example, Patent Literature 1 stores book data including character data for each frame, image data, browsing control information including order information for displaying a plurality of frames, frame moving time information, and the like in advance. There has been proposed an electronic information processing apparatus that enlarges and displays an image of each frame on a display screen in a predetermined order based on the browsing control information.

  Further, in Patent Document 2, image data composed of a plurality of frames arranged in a single page along a story, the display order of frames included in one page, and the display magnification of each frame are preset. When displaying an electronic content file, the image data of the entire page is first displayed on the display screen, and each frame is displayed at the display magnification set for each frame so that each frame is displayed in the screen area. A content display method has been proposed in which the image data of the entire page is displayed again and reduced.

JP 2011-39520 A JP 2007-164550 A

However, if the user repeatedly performs operations such as enlargement, reduction, and movement as necessary, displaying the frames in the order of the story is heavy and the user is burdened with the story. You may not be able to concentrate and your impression on the reader may be disturbed.
In addition, any of the above-mentioned patent documents can be viewed by enlarging and displaying each frame in the display screen in the display order set in advance at the time of content creation. Since the size of the image or characters in the enlarged frame is changed in the middle, the image or characters may suddenly become difficult to see, and some users may find it difficult to read.
The size of the frame is also considered to be part of the story intended by the author, so if the size of the image changes each time the display of the frame is switched, the sensitivity that the author intended may not be fully communicated to the reader. .

  Therefore, the present invention has been made in consideration of the above-described circumstances, and enables a user viewing image content to set a display magnification and the like preferable for the user, thereby reducing the operation burden on the user. It is an object of the present invention to provide an information display device that can sequentially view images in units of scenes so as not to hinder the readability of the user and the impression given to the reader intended by the author as much as possible.

  The present invention is an information display device for displaying content composed of a plurality of frame images in which one page is divided by a scene frame, and a moving direction for sequentially displaying a display unit and frame images belonging to one page An input unit for inputting a transition order for specifying a frame image and an enlargement ratio of the frame image, and an initial display reference point serving as a reference for selecting a frame image to be displayed on the display unit based on the input transition order A reference point setting unit for setting a display area, an enlarged display for determining a display area in a page including a frame image to be displayed based on the display reference point and the enlargement ratio, and displaying the display area on the display unit An information display device comprising: a processing unit, wherein the display area is moved based on the transition order, and frame images belonging to one page are sequentially displayed on the display unit. That.

  According to this, since the frame images included in one page are sequentially displayed on the display unit at the input enlargement rate, the operation burden on the user is reduced and the enlargement rate is constant to the input one. By doing so, it is possible to prevent the readability of the user's content from being disturbed by the author's intended impression on the reader.

In addition, the transition order includes information that defines the display order in the horizontal direction within one page, information that defines the display order in the vertical direction within one page, and which of the moving directions is either horizontal or vertical. It is characterized by comprising priority direction information indicating whether or not the priority is given.
Further, for each frame image belonging to one page, an intersection extraction unit that extracts an intersection that defines one frame image, and the position of the extracted intersection based on the current display reference point and the transition order A reference point update unit that selects one intersection satisfying a predetermined relative relationship with the display reference point and sets a display reference point of a frame image to be displayed next from the selected intersection; It is characterized by that.

  Further, the reference point update unit selects an intersection having the shortest movement distance in the movement direction indicated by the priority direction information of the transition order from the current display reference point among the intersections extracted by the intersection extraction unit. A point having the same coordinates as the selected intersection is set as a new display reference point in the moving direction indicated by the priority direction information.

  In addition, when the enlarged display processing unit determines a display area to be displayed at the input magnification, the entire frame image to be displayed based on the display reference point is displayed in the display area. When the image cannot be displayed, the frame image to be displayed is divided, and the entire frame image is displayed in a plurality of times.

  According to the present invention, the display area including the frame image is determined based on the input transition order, and the frame image included in one page is sequentially displayed on the display unit at the input magnification rate. Reducing the user's operation burden, maintaining the readability of the user's content by making the magnification rate constant to what was entered, and preventing the author's intended impression on the reader as much as possible Frame images can be displayed.

<Configuration of Information Display Device of the Invention>
FIG. 1 is a block diagram showing the configuration of an embodiment of the information display apparatus according to the present invention.
In FIG. 1, the information display device mainly includes a control unit 1, a display unit 2, an input unit 3, an enlarged display processing unit 4, a reference point setting unit 5, a reference point update unit 6, a storage unit 7, and an intersection extraction unit 8. Is provided.
The information display device having such a configuration particularly has a function of displaying content including a plurality of frame images in which one page is divided by a scene frame.

The control unit 1 is a part that controls the operation of each functional block in order to realize various functions of the information display device of the present invention. The control unit 1 is a micro that mainly includes a CPU, ROM, RAM, I / O controller, timer, and the like. Consists of a processor.
Moreover, the function of the information display apparatus of this invention is implement | achieved when CPU operates various hardware based on the control program memorize | stored in ROM etc. FIG.
The information display device of the present invention is incorporated in, for example, a personal computer, an electronic book terminal, a tablet terminal, a mobile phone, and other portable terminals, and the following functions are realized as a part of these electronic devices. .

The display unit 2 is a display device such as an LCD or an organic EL display. In the case of a mobile terminal, a relatively small display device is used.
The input unit 3 is a part for inputting various information, and a keyboard, a mouse, a touch panel, or the like is used.
In the present invention, the input unit 3 is a part for inputting transition rules as will be described later, and in particular, a transition order for specifying a moving direction for sequentially displaying frame images belonging to one page, and enlargement of the frame image Enter the rate and
When the information display device of the present invention is a small and lightweight portable terminal, a touch panel is placed on the display screen of the display unit 2, and a display screen is arbitrarily selected using a pen or a finger. From the viewpoint of operability, it is preferable to input information such as characters and input instructions for enlarging, reducing, and moving images and the like by touching the position.

The enlarged display processing unit 4 is a part that enlarges a part of the image displayed on the display unit 2 at a predetermined magnification or a magnification instructed by a touch operation and displays it on the display screen.
For example, in a page composed of a plurality of frames, the image is enlarged and displayed so that one frame selected according to a predetermined transition rule R is almost within the display screen.

In particular, the enlarged display processing unit 4 includes a page including a frame image to be displayed on the display unit 2 based on a display reference point set by a later-described reference point setting unit 5 and an enlargement ratio input by the input unit 3. The display area is determined and the display area is displayed.
Further, based on the input transition order, the display area is moved in the set movement direction, and frame images belonging to one page are sequentially displayed on the display unit 2.

Further, the enlarged display processing unit 4 performs frame image division display as shown in FIG.
For example, when the display area to be displayed at the input magnification is determined, the entire frame image to be displayed based on the display reference point cannot be displayed in the determined display area. The frame image to be displayed is divided and displayed in the display area, and the entire frame image is displayed in a plurality of times. Details of the enlarged display will be described with reference to flowcharts of FIGS.

The reference point setting unit 5 is a part for initially setting the display reference point C.
In particular, this is a part for setting an initial display reference point that serves as a reference for selecting a frame image to be displayed on the display unit 2 based on the transition order input by the input unit 3. The reference point setting unit 5 performs the processing shown in the flowchart of FIG.
The display reference point C means the coordinates of a point serving as a reference for specifying the position of the frame A with respect to the page including the frame A in order to enlarge and display one frame A.
FIG. 9 is an explanatory diagram of an example of a state where one entire page is displayed on the display screen of the display unit 2.
In FIG. 9A, one page image is composed of five frame images (G1 to G5) divided by five scene frames (frames).
Hereinafter, since the scene frame and the frame image correspond one-to-one, the frame image is also referred to as a frame.
The information of one page image includes, in addition to image information for each frame included in the page, information on the number of frames and information (coordinate values) indicating where each frame is displayed in the page. The

FIG. 9B shows an example of the position of the display reference point C of each frame, the coordinates of the display reference point C, and the intersection that defines the frame.
Here, when it is assumed that one frame is an area surrounded by a plurality of straight lines, a point where two straight lines intersect is a crossing point. For example, if one frame is an area surrounded by four straight lines, the position of the frame is defined by the coordinates of four intersections. The coordinates of the intersection are determined from the X coordinate in the horizontal direction and the Y coordinate in the vertical direction, and the upper right corner of the page is the origin (0, 0).

For example, the top right frame G1 in FIG. 9A is a quadrilateral region surrounded by four intersection points (P0, P1, P5, P4). FIG. 9B shows four intersection points. Of these, the upper right intersection P0 is set as a display reference point C, and the coordinates of the display reference point with respect to the entire page are (X0, Y0).
Similarly, the lower left frame G5 is a quadrilateral region surrounded by four intersections (P6, P8, P11, P10), and the display reference point C is P6 (X6, Y6). Yes.
When only one frame is enlarged and displayed on the display screen, an area to be displayed is determined based on the intersection of the frames and the display reference point C.

As the display reference point C, one intersection is selected from a plurality of intersections specifying one frame. As shown in FIG. 9B, the upper right intersection may be the display reference point C, or the lower right intersection may be the display reference point C.
The display reference point C is initially set by, for example, a flowchart of FIG.
FIG. 9B shows an example in which the upper right intersection of each frame is selected as the display reference point C corresponding to the case where the story of the content proceeds in the order of frames G1, G2, G3, G4, and G5. ing. However, the present invention is not limited to this, and the display reference point C is set according to the frame arrangement order and the frame size and shape corresponding to the development of the content story intended by the author.
For example, if the story progresses from left to right in the order of frames G3, G2, and G1, the upper left intersection of each frame is set as the frame display reference point C.
The initial setting of the display reference point C is set based on the input transition rule R.

FIG. 10 shows an explanatory diagram of an embodiment in which one frame is enlarged and displayed.
In FIG. 10A, it is assumed that the upper right frame G1 is selected as the frame to be displayed and P0 (X0, Y0) is set as the display reference point C. In this state, when the enlarged display of the frame G1 is performed with reference to the display reference point C (P0), the frame G1 is displayed as shown in FIG. 10B, for example.
That is, when the display reference point C is set, an intersection that identifies the area of one frame including the reference point C can be extracted. Therefore, a frame area defined by the display reference point and the extracted intersection is a predetermined area. It is enlarged at the enlargement ratio and displayed on the display screen.

The intersection extraction unit 8 shown in FIG. 1 is a part that extracts intersections that define one frame image.
As described above, in order to specify the position of a frame image having a shape such as a quadrilateral, an intersection that specifies the outer frame of the frame is extracted.

The reference point update unit 6 shown in FIG. 1 is a part that newly sets a display reference point C in order to display the next frame when an enlarged display is performed.
More specifically, the reference point update unit 6 has a positional relationship with the current display reference point among the positions of the intersection extracted by the intersection extraction unit 8 based on the current display reference point and the input transition order. This is a part for selecting one intersection satisfying a predetermined relative relationship and setting a display reference point of a frame image to be displayed next from the selected intersection.

The predetermined relative relationship means the relationship between the intersection and the display reference point (X, Y) coordinate values when the X axis and the Y axis are set in the horizontal and vertical directions, respectively.
In addition, there are the following as selection criteria for one intersection.
That is, of the intersections extracted by the intersection extraction unit 8, the intersection having the shortest movement distance in the movement direction indicated by the priority direction information of the transition order is selected from the current display reference point. Then, the reference point update unit 6 sets a point having the same coordinates as the intersection selected for the moving direction indicated by the priority direction information as a new display reference point.
The reference point update unit 6 performs the processing shown in the flowchart of FIG.

For example, when the frame G1 is enlarged and displayed as shown in FIG. 10B and the next frame to be displayed is the frame G2, the display reference point C is changed from the intersection point P0 to the intersection point P1.
Thereby, the area of the frame G2 to be displayed based on the new display reference point P1 (area defined by the intersection points P1, P2, P7, and P5) is selected and displayed in an enlarged manner.
When the three frame images (G1, G2, G3) shown in FIG. 11 are displayed in the order of G1, G2, and G3, the display reference point is the point P0 in FIG. 11 (a) and FIG. 11 (b). The point P1 and the point C1 in FIG. 11C are updated in this order.
The next frame to be displayed is selected according to a predetermined transition rule R.

The storage unit 7 is a part for storing information necessary for the enlarged display and the like of the present invention, and ROM, RAM, hard disk and the like are used.
The program for performing display control or the like of the present invention is stored in advance in a ROM or a hard disk, and the transition rule R that has been set and information that is used when each processing is performed and stored each time is stored in the RAM or the hard disk. .
As shown in FIG. 1, the storage unit 7 mainly serves as a transition rule R, content to be displayed 73 including information such as characters and images, intersection information 74 for specifying a frame, and a base point for displaying the frame. Reference point information 75, display position information 76 for specifying a display position for one page, a variable 77 used when each process is executed, and the like are stored.

The transition rule R is information including information (transition order) 71 indicating the order in which frames included in one page are displayed, and an enlargement ratio K72. However, other information may be included.
The transition order 71 means information for specifying a moving direction for sequentially displaying a plurality of frame images belonging to one page, mainly information defining a horizontal display order in one page, and a vertical direction Information indicating the display order of the display area, and information (priority direction information) indicating which of the moving directions of the display area is given priority to the horizontal direction or the vertical direction.

The information that defines the display order in the horizontal direction is “left”, which means that the frame on the right side is displayed first and the frame on the left side is displayed after that, or the frame on the left side is displayed first. One of “right”, which means to display the frame on the right side after that, is set.
For example, if the story progresses in the order from the right frame to the left frame, it is better to move the displayed frame from the right side to the left side.

The information that defines the display order in the vertical direction is “up”, which means that the upper frame is displayed first and the lower frame is displayed after that, or the lower frame is displayed first. One of “below” is set, which means that the frame is displayed and the frame on the upper side is displayed after that.
The enlargement factor K72 means a magnification for displaying each frame included in one page in an enlarged manner. For example, the magnification for displaying one entire page on the display screen is set to 1, and the display magnification for this is set. The

The transition rule R may be given as initial information attached to the content 73 in advance, or may be set in advance by a user who intends to display the content 73 in the future.
Depending on the content 73, since the arrangement of each frame in one page is usually fixedly determined, the transition order 71 is preferably fixed in advance.
However, since it is considered that the reader's readability varies with the size of the displayed image or character, it is preferable that the enlargement factor K72 can be set by the user before display. .

The content 73 is information displayed on the display unit 2, for example, information such as a book, a comic, and a pamphlet. Further, the content 73 may be composed of so-called multimedia information including characters, graphics, images, and the like.
On media without a frame, the entire page is enlarged and displayed as a single frame.
The content 73 is mainly stored in the hard disk, but may be content stored in a recording medium such as a USB memory, a CD, or a DVD, or content downloaded via a network.

The intersection information 74 is information for specifying the intersection shown in FIG. 9 and the like, and is mainly given by the coordinate values (X, Y) of the vertices of the quadrilateral that specify each frame. This intersection information 74 can be extracted from the page image information as described above, for example.
The reference point information 75 is information for specifying the display reference point C described above, and includes a display reference point C, a horizontal movement point C1, and a vertical movement point C2. The display reference point C is specified by coordinate values (X, Y) for one page.
When the next frame to be displayed is selected, the horizontal movement point C1 means a point that becomes a candidate for the next display reference point when moved in the horizontal direction as viewed from the current display reference point C.
When the next frame to be displayed is selected, the vertical movement point C2 means a point that becomes a candidate for the next display reference point when moved in the vertical direction when viewed from the current display reference point C.

As the horizontal direction movement point C1 and the vertical direction movement point C2, an intersection of frames is mainly selected, but depending on the shape of the frame, a point that is not an intersection of frames may be selected.
For example, when selecting the frame on the left side as the next frame to be displayed, among the intersections specifying the left frame, the intersection with the shortest movement distance of the X coordinate in the horizontal direction when viewed from the current display reference point C A point having the same X coordinate and the same Y coordinate as the display reference point C is defined as a lateral movement point C1 (see FIG. 11C).
In addition, when selecting a frame on the lower side as the next frame to be displayed, the movement distance of the Y coordinate in the vertical direction as viewed from the current display reference point C among the intersections specifying the frame on the lower side A point having the shortest intersection Y coordinate and the same X coordinate as the display reference point C is defined as a longitudinal movement point C2.

FIG. 11 is an explanatory diagram of a specific example in setting the lateral movement point C1.
In FIG. 11A, when there are three frames (G1, G2, G3) on one page and the frame G1 is displayed, the display reference point C is at the position of the upper right intersection P0 of the frame G1. It is shown that. The coordinates of the intersection point P0 are the coordinates of the origin of the page (0, 0).

In the state of FIG. 11A, when moving next in the horizontal direction and displaying the frame G2 adjacent to the left of the frame G1, the horizontal movement point C1 is set as shown in FIG. 11B.
In the case of FIG. 11A, the intersection that defines the frame G2 at the intersection left of the intersection P0 that is the current display reference point C is the intersection of P1 and P2 that have the same Y coordinate as the intersection P0 and the Y coordinate. P5 and P6 are different from P0. Here, when the X coordinate values are compared, in the case of FIG. 11A, there is a relationship of 0 <X1 <X5 <X6 <X2.

In this case, it is the intersection P1 that has the shortest movement distance in the horizontal direction when viewed from the intersection P0 of the display reference point C.
The movement distance in the horizontal direction means the distance in the X coordinate direction (the length of the X coordinate value) between two intersections.
Therefore, as shown in FIG. 11B, the intersection point P1 is set as the lateral movement point C1.
When the transition order of the transition rule R is “left” indicating movement from right to left, the horizontal movement point P1 is set as a new display reference point C. The frame G2 is displayed on the basis of the intersection P1 that has become the new display reference point C.

FIG. 11C shows the setting of the lateral movement point C1 when moving further leftward from the state of FIG. 11B and displaying the frame G3 adjacent to the left of the frame G2.
In FIG. 11B, since the display reference point C is the intersection point P1, among the intersection points on the left side of the intersection point P1, there are four intersection points (P2, P3, P7, P6) that define the frame G3. It is.
Here, when the X coordinate values of the four intersections are compared, there is a relationship of X1 <X6 <X2 <X3. The X coordinates of the intersection points P3 and P7 are both X3.
Therefore, among these four intersections, the intersection P6 has the shortest moving distance in the horizontal direction (X coordinate direction) when viewed from the intersection P1 which is the display reference point C.
However, the Y coordinate (Y4) of the intersection P6 is different from the Y coordinate (0) of the display reference point P1.

Therefore, as the lateral movement point C1, a point having an X coordinate that is X6 of the intersection P6 having the shortest movement distance and a Y coordinate that is the same value (0) as the display reference point P1 is selected.
That is, as shown in FIG. 11 (c), a coordinate value (X6, 0) point is set as the lateral movement point C1.
When the transition rule R is “left” indicating movement from right to left, the point of this coordinate value (X6, 0) is set as a new display reference point C. Thereafter, the frame G3 is displayed with the new display reference point (X6, 0) as a reference.

FIG. 12 is an explanatory diagram of a specific example in setting the vertical direction movement point C2.
FIG. 12A shows a case where the display reference point C is the intersection point P0.
In this state, if the next frame to be displayed is the downward frame G4, among the four intersections (P4, P6, P9, P10) that define the frame G4, Y is viewed from the display reference point P0. The intersection P4 (0, Y4) having the shortest movement distance in the coordinate direction is selected as the vertical movement point C2.
Therefore, as shown in FIG. 12B, the intersection point P4 is set as the vertical movement point C2 when the frame G4 is displayed.
When the vertical movement point P4 is set as the display reference point C, the frame G4 is displayed with the intersection point P4 as a reference.

In FIG. 1, display position information 76 is information used when a frame is divided and displayed when the frame is enlarged. This is information used in the processing shown in the flowcharts of FIGS.
The display position information 76 includes a display position C1 ′ (X, Y) as a reference for division display, a horizontal movement point C1 ′ for determining the division display position, and a vertical movement point C2 ′. Become.

Depending on the relationship between the actual size of the frame and the size of the display screen when the frame is enlarged at a specified magnification, the entire frame may not be displayed on the display screen.
FIG. 13 is an explanatory diagram of the relationship between the frame to be enlarged and the size of the display screen.
FIG. 13A illustrates an example of a relationship between the frame G1 and the display screen size when the frame G1 is enlarged and displayed.
As shown in FIG. 13A, it is assumed that the size of the display screen 21 of the display unit 2 includes all the frames G1 and is a size that can also display a part of the left adjacent frame G2.

For example, as shown in FIG. 9A, when the user performs an operation of enlarging and displaying the frame G1 in a state where the entire image of one page is displayed, the intersection point P0 is the display reference point C. The frame G1 is displayed based on the preset enlargement ratio K72.
That is, the area including the frame G1 displayed in FIG. 9A is enlarged at the magnification set as the enlargement factor K72 and displayed on the display screen 21 of the display unit 2.

When the enlargement factor K72 is set by the user in advance as a magnification that is easy to see, all frames are displayed at the set magnification K unless there is an input for instructing the change of the magnification thereafter. .
Therefore, when another frame is enlarged and displayed thereafter, the relative relationship between the actual size of each frame and the display screen size is the same.
It is possible to change the enlargement ratio each time so that the entire frame always fits within the display screen according to the size relationship of the frames, but in this case, the size of the frame changes. Each time, the size of images and characters displayed on the screen also changes, which may be difficult for the user to see.
Therefore, in the present invention, in consideration of the user's visibility, the enlargement ratio K set by the user is respected, and the enlargement display of each frame is performed while keeping the enlargement ratio constant in principle.

However, when the enlargement ratio K is constant, in the case of FIG. 13A, the size (area) of the frame G4 is larger than the size (area) of the frame G1, so that the frame G4 moves downward. When trying to display, the entire frame G4 cannot be displayed in the same display screen size.
Thus, when one frame cannot be displayed in the display screen size and there is a protruding part, the display is divided.

First, FIG. 13B shows a case where the upper part of the frame G4 is displayed when the frame G4 is divided and displayed in an enlarged manner.
Here, the intersection P4 at the upper right of the frame G4 is set as the display position C ′ of the display position information 76, and the area of the frame G4 that fits within the screen of the same size as the display screen 21 shown in FIG. Only is displayed.
In FIG. 13, in order to simplify the description, the length in the vertical direction (Y coordinate) of the frame G4 is approximately twice the length in the vertical direction of the frame G1. In this case, the substantially upper half area of the frame G4 is displayed.

Next, as shown in FIG. 13C, when the remaining lower half of the frame G4 is displayed, a vertical movement point C2 ′ for division display is set.
Here, the vertical movement point C2 ′ is moved downward by a length corresponding to the length in the vertical direction (Y coordinate) of the display screen 21 when viewed from the intersection P4 which is the current display position C ′. A point is set.
When the length of the display screen in the vertical direction is Ly and the coordinates of the intersection P4 are (0, Y4), the coordinates of the vertical movement point C2 ′ are (0, Y4 + Ly). The vertical movement point C2 ′ is set as the display position C ′, and the next display area is determined based on the display position C ′.

FIG. 13C shows a case where the lower half of the frame G4 is displayed on the display screen.
However, if the area of the frame G4 that cannot be displayed below is left in the second divided display of the frame G4, the vertical direction of the display screen is similarly lowered. The next vertical movement point C2 ′ moved to is set, and the third divided display is performed for the remaining area of the frame G4.

FIG. 14 is an explanatory diagram when the entire frame G4 is displayed on the display screen from the enlarged display state of the frame G1.
FIG. 14A is the same diagram as FIG.
FIG. 14B is a diagram in which the entire frame G4 larger than the frame G1 is displayed on the display screen.
In FIG. 14B, since the frame G4 is larger than the frame G1, the enlargement ratio K needs to be smaller than that in the case of FIG. 14A in order to fit the entire frame G4 in the same display screen.
Thereby, it is possible to grasp the entire image inside the frame G4.
However, since the entire frame G4 is displayed, the size of images and characters included in the frame G4 is relatively small and displayed, which is difficult to see.

On the other hand, in FIG. 13, when the enlarged display of all the frames included in one page is performed at a preset magnification K, the size of the frames is relatively larger than the size of the display screen 21. Has a split display.
At this time, since one frame is divided and displayed separately, the contents of one frame cannot be checked at a glance, but the size of images and characters included in each frame is unified for all frames. Since it is displayed and does not suddenly increase or decrease depending on the size of the frame, the visibility of the content does not change.

If the entire frame is to be displayed on the display screen after viewing the divided display in FIGS. 13B and 13C, a predetermined operation that means a reduction in the display size is performed, so that FIG. ) As shown in FIG.
Alternatively, conversely, when a predetermined operation is performed after the display including the entire frame as shown in FIG. 14B is performed first, or after a predetermined time has elapsed, FIGS. 13B and 13C. ) May be divided and displayed.

In FIG. 1, the storage unit 7 stores several variables 77 in addition to the above information.
For example, the number P of the currently displayed page in the content 73 composed of a plurality of pages, the total number MP of the content 73, the magnification Z that is the enlargement ratio of the page currently displayed on the display screen, and an attempt to display. A magnification (pseudo magnification) Z ′ or the like when the entire frame is displayed so as to fit on the display screen is stored. These variables are used in the flowcharts of the processes shown below.

FIG. 15 is an explanatory diagram showing one embodiment of the display order of the enlarged display of frames according to the present invention.
Here, as the transition order 71 of the transition rule R, the priority direction is set to the horizontal direction, and the horizontal movement direction is set to “left” meaning right to left.
In addition, it is assumed that a magnification that allows the frame G1 to fit in the display screen is set in advance as the enlargement factor K72.
In addition, the enlargement ratio K is constant except when it is necessary to perform split display or when the enlargement ratio is intentionally changed by the user.
In FIG. 15A to FIG. 15I, an example in which five frames (G1 to G5) included in a page with a page number P in the given content 73 are displayed in order. Show.

Since the transition order 71 of the transition rule R is set in the order from right to left with priority in the horizontal direction, the top right frame G1 is selected as the first frame to be displayed.
First, in FIG. 15A, the intersection P0 of the upper right frame G1 included in this page is selected as a display reference point, and an area including the frame G1 enlarged at the set enlargement ratio K is displayed on the display screen. 21 is displayed.
At this time, if the size of the frame G1 is not the same as the aspect ratio of the display screen 21, a part of the frame G2 adjacent to the left is also displayed.
However, when it is desired to explicitly display only the information in the area of the frame G1, only the luminance of the portion of the frame G1 to be displayed is increased, or the luminance of the portion of the frame G2 that is not the current display target is displayed. You may make it difficult to see by dropping.

Next, in FIG. 15B, in accordance with the transition order 71, the frame G2 on the left side of the frame G1 is enlarged and displayed.
Here, the area including the frame G2 is displayed on the display screen 21 while the enlargement factor K remains the same as that in FIG.
In this case, the intersection point P1 of the frame G2 is set as the lateral movement point, and this point P1 becomes the display reference point C.
Next, since the frame G3 is on the left side of the frame G2, the frame G3 is further moved to the left side, and an area including the frame G3 is enlarged as shown in FIG.
In FIG. 15C, since there is no frame on the left side of the frame G3, the entire frame G3 and a part of the right frame G2 are displayed on the display screen 21.

According to the transition order 71 of the transition rule R, there is no frame even if an attempt is made to display the left frame of the frame G3, so the display screen is moved downward in the vertical direction. At this time, instead of the lower side of the frame G3, the screen returns to the right end of the page and the lower frame of the frame G1 is selected.
By examining the intersection of each frame in the page, it can be seen that there is a frame G4 below the first top right frame G1.
Further, considering the positions of the four intersections of the frame G4 and the enlargement ratio K with respect to the size of the current display screen 21, the entire frame G4 does not fall within the current display screen size and protrudes. I understand that.

Therefore, the enlargement factor K is adjusted so that the entire frame G4 falls within the display screen 21, and an area including the entire frame G4 is displayed as shown in FIG. Here, the enlargement factor K is adjusted to be small.
The reason why the enlargement ratio K is adjusted in this way is to have the user confirm the entire frame G4.
However, when it is not necessary to check the entire frame, it is not necessary to display with the magnification ratio changed as shown in FIG.
In FIG. 15D, since the entire frame G4 is displayed so as to fit on the display screen 21 having the same size as that in FIG. 15A, a part of the left adjacent frame G5 is also displayed. At this time, since only the frame G4 is confirmed, the luminance of the frame G5 may be lowered.

Next, in FIG. 15 (e), the frame G4 is divided and displayed using the same enlargement ratio K as in FIGS. 15 (a) to 15 (c).
Here, the intersection point P4 of the frame G4 is selected as the display reference point, and a partial region (corresponding to the upper half) of the frame G4 is displayed on the display screen 21.
Further, in FIG. 15F, the display screen 21 is moved downward by the length of the display screen 21 in the vertical direction, and the remaining area (corresponding to the lower half) of the frame G4 is displayed on the display screen 21. Let

Next, according to the transition order 71 of the transition rule R, the frame G5 on the left side of the frame G4 is displayed.
In FIG. 15, similarly to the frame G <b> 4, the frame G <b> 5 does not enter the display screen 21 at the same enlargement ratio K, and thus is divided and displayed.

Although omitted in FIG. 15, the area including the entire frame G5 may be displayed on the display screen 21 by adjusting the enlargement factor K as shown in FIG. 15D before FIG. Good.
In FIG. 15G, a partial area (corresponding to the upper half) of the frame G5 is displayed on the display screen 21 with the enlargement factor K being the same as in FIG.
Next, as shown in FIG. 15 (h), the remaining part of the frame G 5 (lower right region) is displayed on the display screen 21. At this time, an area having the intersection P10 of the frame G5 as the display reference point C is displayed on the display screen 21.
However, in FIG. 15 (h), the left part of the frame G5 that has not yet been displayed remains.
Therefore, in FIG. 15 (i), in order to display the remaining part (the left half area of the lower half) of the frame G5, the display screen 21 is moved leftward, and the area including the remaining part is divided and displayed.

As described above, the five frames included in one page are sequentially enlarged and displayed in the order shown in FIGS.
In this enlarged display, the same enlargement factor K is used except for the entire display of FIG. 15D for the frame G4 that needs to be divided and displayed.

<Operation of Information Display Device of the Invention>
An embodiment of the operation of the information display device according to the present invention will be described below.
It is assumed that the user of the information display apparatus of the present invention records the content desired by the user in the storage unit 7 and displays the content 73 on the display unit 2 to confirm the content.
Therefore, the user records in advance the content 73 to be displayed in the storage unit 7 by downloading via a recording medium such as a CD-ROM or USB memory, or a network such as the Internet or LAN.
Further, as described above, the content handled in the present invention is composed of a plurality of frames in which one page is divided by scene frames. Further, it is assumed that the total number of pages is also stored in each content 73.

<Transition rule setting process>
FIG. 2 shows a flowchart of an embodiment of the transition rule setting process of the present invention. In this setting process, the transition order 71 and the enlargement ratio K72 shown in FIG. 1 are mainly set.
In step S1, an enlargement factor K72 is set. Here, the control unit 1 causes the storage unit 7 to store the numerical value of the enlargement factor K input by the user through the input unit 3.
The input of the enlargement factor K may be input by a slider, a pinch gesture or the like in addition to the direct input using the keyboard.

In step S2, the transition order 71 is selected and input. Here, the control unit 1 causes the storage unit 7 to store information for determining the transition order 71 input by the user through the input unit 3.
As shown in FIG. 1, the transition order 71 includes a frame advance direction (left or right) in the horizontal direction, a frame advance direction (up or down) in the vertical direction, and a frame movement priority direction (horizontal or Vertical) information. The selection input of this information may be performed by displaying options that can be set on the display unit 2 and allowing the user to input any of the options.

For example, if the content you want to display is a creation that consists of frames where the sequence of frames is right-to-left and the story progresses from upper-right to lower-left on all pages, Select “left” as the horizontal direction, “down” as the vertical direction, and “horizontal” as the priority direction.
The above is one example of the setting process.
In addition, when such setting input is not performed, a warning display requesting that setting input be performed on the display unit 2 may be displayed. Alternatively, a transition rule R that is considered to be frequently used is set in advance as an initial value at the time of shipment, and this initial value may be used when no setting input is made.
Further, the setting value of the previous transition rule R is stored, and this setting value may be used when no setting input is made.

<Content display processing>
FIG. 3 shows a flowchart of an embodiment of content display processing.
Here, when the content 73 to be displayed is selected, the content is displayed on the display unit 2 for each page, and the frames included in the page are displayed in an enlarged manner, according to the transition rule R set in FIG. To display the frame.

In step S <b> 11, the control unit 1 causes the user to select the content 73 to be displayed, reads the selected content from the recording unit 7, and develops it in the storage unit 7 so that it can be displayed on the display unit 2.
When a plurality of contents 73 are stored in the storage unit 7, for example, a list screen including the names of these contents is displayed on the display unit 2, and the user can select and input the contents to be displayed. That's fine.
Further, the total number of pages of the selected content 73 is also read and set in the variable MP of the total number of pages.

In step S12, the page number variable P of the page to be displayed is initialized. For example, 1 is set in the variable P.
In step S <b> 13, the control unit 1 causes the display unit 2 to display the entire page indicated by the page number of the variable P.
For example, as shown in FIG. 9A, the page size is adjusted so that all the frames included in one page can be seen, and the entire page is displayed on the display screen 21.
However, when it is not necessary to display the entire page, it may be set in advance so that the entire page is not displayed by a predetermined setting input.

In step S14, the control unit 1 checks whether or not an enlargement operation input has been made.
The user looks at the screen of the entire page displayed in step S13, and sets a magnification that is easy for the user to see. For example, in the case of a touch panel, an enlargement operation such as a pinch gesture may be performed. If an enlargement operation input has been made, the process proceeds to step S16, and if not, the process proceeds to step S15.

In step S15, it is confirmed whether the enlargement ratio K has already been set. If the storage unit 7 is checked and the enlargement ratio K is set, the process proceeds to step S17, and if not, the process proceeds to step S18.
In step S16, the enlargement factor K is updated according to the contents of the enlargement operation input. Here, for example, when a new numerical value of the enlargement ratio is input, the expansion ratio K is set to the input numerical value. Thereafter, the process proceeds to step S17.

In step S17, an enlarged display process for each frame is performed on the current page. Here, on the basis of the set transition order 71, the frames included in the page are sequentially enlarged and displayed using the set enlargement ratio K72. Details of this enlarged display processing are shown in FIG.
In step S17, when the display of all the frames in one page is completed, the process proceeds to step S18.
In step S18, 1 is added to the page number variable P in order to select the next page.
In step S19, it is checked whether or not the current page number P is larger than the total number of pages MP.
That is, in the case of P> MP, since all pages of the content that is the current display target are displayed, the process is terminated.
If P ≦ MP, there are still pages to be displayed, so the process returns to step S13 and the processes from step S13 to step S18 are repeated.
The above is the display processing of each page constituting the content.

<Enlarged display processing>
FIG. 4 shows a flowchart of an embodiment of the enlarged display process of the present invention. This shows the specific processing content of step S17 shown in FIG.
In step S31, the transition rule R is read from the storage unit 7.
In step S32, the set enlargement factor K is set (substituted) in the magnification variable Z.
In principle, the subsequent enlarged display is performed for all frames based on the value set in the magnification variable Z.

In step S <b> 33, the entire image of the page P that is currently displayed is displayed in a Z-magnification, and the page image data that has been Z-magnified is stored in the storage unit 7.
At this time, since the page image is multiplied by Z, only a part of the page image is displayed on the display screen of the display unit 2.
For example, as one example, a part of the page image is displayed as shown in FIG. 10B from the display state of FIG.

In step S34, the storage unit 7 is checked to check whether or not the display reference point C is currently not set. If it has not been set, the process proceeds to step S35, and if it has already been set, the process proceeds to step S36.
In step S35, the reference point setting unit 5 initializes the display reference point C. Specifically, based on the transition rule R, the X coordinate and the Y coordinate of the display reference point C are set.
Details of this initial setting processing are shown in FIG.

In step S36, the intersection extraction unit 8 extracts the intersections of scene frames (frames) included in the entire image of the current page P.
For example, in the case of a page image as shown in FIG. 9A, the coordinates of each intersection of five frames (G1 to G5) included in the page are obtained. When the intersection P0 on the upper right of the page image in FIG. 9A is the origin of the page, the coordinates of the intersection P0 are (0, 0), and the relative positions of the other intersections (P1 to P11) with respect to the intersection P0. Find the coordinates.

In step S37, it is checked whether or not there is an area where the number of intersections included in the display area of the current display screen is less than 4 for the image obtained by multiplying the page P in step S33 by Z.
If the number of intersections displayed in the display area of the current display screen is less than 4, the process proceeds to step S41. If there are 4 or more points, the process proceeds to step S38.
In step S38, since there are four or more intersections in the area to be displayed, there are a plurality of frames in the display area of the display screen. Therefore, all frames displayed in the display area are displayed as they are in order to allow the user to input settings for further enlarged display.

In step S39, it is checked whether or not the user has made an input meaning an enlargement operation. If there is an input, the process proceeds to step S40, and if not, the process proceeds to step S42.
In step S40, when there is an enlargement operation input, the enlargement factor K of the transition rule R is updated to the enlargement factor specified by the input.
Thereafter, the process returns to step S31, and the display is again performed with the updated enlargement factor K.

In step S41, if there are less than 4 intersection points (3 points or less) in the current display area, the frame displayed on the display screen 21 can be identified as almost one, and therefore exists in the display area. The enlarged display process of the frame is performed for the frame while moving the display screen.
As a result, the entire frame is displayed in such a size that it can be displayed on the display screen, or if the entire frame cannot be displayed with the current enlargement factor K, split display is performed. . Details of the frame enlargement display processing are shown in FIG.

In step S41, after one frame enlargement display process is performed, the process proceeds to step S42.
In step S42, it is checked whether or not all the frames included in the current page P have been displayed. For this check, for example, it may be confirmed whether or not the four corners of the page are displayed. When all the frames are displayed, since all the enlargement processing for the page P is completed, the processing ends.
By checking the above, if the four corners of the page are not displayed, it can be seen that there are still frames to be displayed. Therefore, in order to display the remaining frames, the process proceeds to step S43, and the reference The point update unit 6 updates the display reference point C.
Details of the display reference point C update processing are shown in FIG.
After updating the display reference point C, the process returns to step S37, and the processing of steps S37 to S42 is repeated again to perform the enlargement processing of the remaining frames.

<Initial setting process of display reference point>
FIG. 5 shows a flowchart of an embodiment of the display reference point initial setting process. This shows the specific processing content of step S35 shown in FIG.
In step S51, the reference point setting unit 5 checks whether or not the horizontal direction in the transition order 71 of the transition rule R is set to “left”. That is, it is checked whether or not the moving direction of the frame is from right to left.
In the case of “left”, the process proceeds to step S52. Otherwise, since the horizontal direction is set to “right”, the process proceeds to step S53.

In step S52, since the frame to be displayed is moved from right to left, the X coordinate of the display reference point C is set to the rightmost coordinate of the page image displayed on the display screen 21.
In the case of FIG. 9A, since the line connecting the intersections P0, P4, and P9 is the rightmost side, the X coordinate of these intersections is set as the X coordinate of the display reference point C. For example, when the intersection point P0 in FIG. 9A is the origin (0, 0), zero is set as the X coordinate of the display reference point C.
In step S53, since the frame to be displayed is moved from left to right, the X coordinate of the display reference point C is set to the leftmost coordinate of the page image displayed on the display screen 21.

Next, in step S54, the reference point setting unit 5 checks whether or not the vertical direction of the transition rule R is set to “down”.
That is, it is checked whether or not the frame moving direction is a direction from top to bottom. If “down”, the process proceeds to step S55. Otherwise, since the vertical direction is set to “up”, the process proceeds to step S56.

In step S55, since the frame to be displayed is moved from top to bottom, the Y coordinate of the display reference point C is set to the top coordinate of the page image displayed on the display screen.
In the case of FIG. 9A, since the line connecting the intersection points P0, P1, P2, and P3 is the uppermost side, the Y coordinate of these intersection points is set as the Y coordinate of the display reference point C.
When the intersection point P0 is the origin (0, 0), zero is set as the Y coordinate of the display reference point C.
In step S56, since the frame to be displayed is moved from the bottom to the top, the Y coordinate of the display reference point C is set to the lowest coordinate of the page image displayed on the display screen.

For example, when the horizontal order = “left” and the vertical direction = “down” are set as the transition order 71, steps S52 and S55 are executed, and the initial value of the display reference point C is the page image. The X and Y coordinates of the rightmost and uppermost point are set.
In the case of FIG. 9A, the intersection point P0 is selected as the display reference point C, and when the intersection point P0 is the origin (0, 0), (0, 0) is set as the coordinate value of the display reference point C. The
The above is the initial setting process of the display reference point C.

<Frame enlargement display processing>
FIG. 6 shows a flowchart of an embodiment of an enlarged display process of a frame to be displayed.
This shows the specific processing content of step S41 shown in FIG.
This process assumes that the target frame is one page and performs the process recursively, so that, for example, an enlarged display of the frame as shown in FIG. 10B or FIG. 15A is performed.

In step S71, the pseudo magnification Z ′ is set so that the entire frame in the current display area fits on the display screen. This process is performed in order to display the entire frame once and allow the user to grasp the contents of the entire frame.
The pseudo magnification Z ′ can be obtained from the distance of each intersection of the target frame.

In step S 72, information on the current display reference point C is set in the display position C ′ of the display position information 76.
In step S73, the image in the display area of the display screen 21 is enlarged and displayed at the pseudo magnification Z ′ set in step S71 based on the display position C ′.
At this time, for example, when the display reference point C is the intersection point P0, the intersection point P0 is set as the display position C ′, so that an area including the entire frame G1 is displayed on the display screen 21 as shown in FIG. Is displayed.
Alternatively, when the display reference point C is the intersection point P4, the intersection point P4 is set as the display position C ′. Therefore, as shown in FIG. 14B, an area including the entire frame G4 is displayed on the display screen 21. Is displayed.

  If the user instructs enlargement display in step S74, the process proceeds to step S78, and a new magnification Z is set. If there is no instruction, the process proceeds to step S75.

  In step S75, the image in the current display area is enlarged and displayed at a preset magnification Z based on the information on the display position C '. As a result, the frames are re-displayed at an enlargement rate preset by the user.

In step S76, it is checked whether or not all parts of the frame currently being displayed are displayed.
This check can be performed, for example, depending on whether or not all intersections of the target frame are displayed.
If all the parts have already been displayed, the process ends. If not, the process proceeds to step S77.
In step S77, the frame to be displayed has a remaining portion that has not been displayed yet, so the information of the display position C ′ is updated in order to display the remaining portion. The update processing of the display position information C ′ is shown in FIG.
After updating the display position C ′, the process returns to step S74 to display the remaining part. For example, the remaining portion of the frame G4 as shown in FIG. 15 (f) is displayed.
This completes the description of the frame enlargement display process.

<Update processing of display reference point C>
FIG. 7 shows a flowchart of an embodiment of the display reference point C update process.
This shows the specific processing content of step S43 shown in FIG. Accordingly, the display reference point C of the next frame to be displayed is set, and the next frame is displayed based on the new display reference point C.

  In step S101, the reference point update unit 6 checks whether or not the lateral movement point C1 is not set. If not set, the process proceeds to step S102, and if not, the process proceeds to step S103.

In step S <b> 102, an intersection point at which the moving distance in the horizontal direction (X coordinate) is the shortest when viewed from the current display reference point C is detected. That is, the intersection with the shortest distance of the X coordinate value is detected. A point composed of the detected X coordinate of the intersection and the Y coordinate of the display reference point C is set as the lateral movement point C1.
For example, as shown in FIG. 11B and FIG. 11C, the lateral movement point C1 is set.
Thereafter, the process proceeds to step S103.

In step S103, the reference point update unit 6 checks whether or not the vertical movement point C2 is not set. If it is not set, the process proceeds to step S104, and if not, the process proceeds to step S105.
In step S <b> 104, an intersection point at which the moving distance in the vertical direction (Y coordinate) is the shortest when viewed from the current display reference point C is detected. That is, the intersection with the shortest Y coordinate value distance is detected. A point composed of the detected Y coordinate of the intersection and the X coordinate of the display reference point C is set as the vertical movement point C2.
Thereafter, the process proceeds to step S105.

In step S105, it is checked whether or not the horizontal direction of the transition rule R is set as the priority direction.
If the priority direction is “horizontal”, the process proceeds to step S106; otherwise (the priority direction is “vertical”), the process proceeds to step S112.

In step S106, it is checked whether or not the lateral movement point C1 is an end point of the page image of the currently displayed page.
Here, the end point means the left end or the right end, and it is checked whether the X coordinate of the lateral movement point C1 is the leftmost end coordinate value or the rightmost end coordinate value.
If it is an end point, the process proceeds to step S109, and if it is not an end point, the process proceeds to step S107. For example, in both FIG. 11 (b) and FIG. 11 (c), since the lateral movement point C1 is not an end point, the process proceeds to step S107.
In step S107, the lateral movement point C1 set in step S102 is set as the display reference point C.
In step S108, the contents of the lateral movement point C1 are deleted, and the process ends.

On the other hand, in step S109, first, the contents of the lateral movement point C1 are erased. Here, since the horizontal movement point C1 is already the position of the end point of the page, it is determined that there are no more frames in the horizontal direction. Therefore, the next frame is selected by moving in the vertical direction.
Next, in step S110, the vertical direction moving point C2 set in step S104 is set as the display reference point C, and in step S111, the vertical direction moving point C2 is deleted and the process is terminated.

In step S112, since the priority direction of the transition rule R is “vertical direction”, whether the vertical movement point C2 is the end point (upper end or lower end) of the page image of the currently displayed page, To check.
If it is an end point, the process proceeds to step S113, and if it is not an end point, the process proceeds to step S110. The process proceeds to step S110 as described above.

On the other hand, when proceeding to step S113, since the vertical movement point C2 is already the end point of the page and there is no frame in the vertical direction, it is necessary to move the frame to be displayed in the horizontal direction.
Therefore, first, in step S113, the vertical movement point C2 is deleted.
In step S114, the horizontal movement point C1 is set as the display reference point C in order to move the frame in the horizontal direction.
In step S115, the lateral movement point C1 is deleted, and the process ends.
With the above processing, the next frame to be displayed on the display screen is selected by updating the display reference point.

<Update processing of display position information C ′>
FIG. 8 shows a flowchart of an embodiment of the process for updating the information on the display position C ′.
This shows the specific processing content of step S77 shown in FIG. As a result, when one frame is divided and displayed, a position (moving point) to be used as a display reference point for the remaining portion after the division is set.
Since the display positions C and C ′ operate according to the same transition rule, the flow is substantially the same as the process shown in FIG.

In step S131, the reference point update unit 6 checks whether or not the lateral movement point C1 ′ of the display position information 76 is not set. If it has not been set, the process proceeds to step S132; otherwise, the process proceeds to step S133.
In step S132, the point moved by a distance corresponding to the horizontal size of the display area of the display screen 21 in the horizontal direction (X coordinate) as viewed from the current display position C ′ is set as the horizontal direction movement point C1 ′. To do.
Thereafter, the process proceeds to step S133.

In step S133, the reference point update unit 6 checks whether or not the vertical movement point C2 ′ of the display position information 76 is not set. If it is not set, the process proceeds to step S134, and if not, the process proceeds to step S135.
In step S134, a point moved by a distance corresponding to the vertical size of the display area of the display screen 21 in the vertical direction (Y coordinate) as viewed from the current display position C ′ is set as the vertical direction movement point C2 ′. To do.
Thereafter, the process proceeds to step S135.

In step S135, it is checked whether or not the horizontal direction of the transition rule R is set as the priority direction. If the priority direction is “horizontal”, the process proceeds to step S136; otherwise (the priority direction is “vertical”), the process proceeds to step S142.
In step S136, it is checked whether or not the lateral movement point C1 ′ is the end point (left end or right end) of the page image of the currently displayed page. This is a process equivalent to step S106.
If it is the end point of the page image, the process proceeds to step S139, and if it is not the end point, the process proceeds to step S137.
In step S137, the lateral movement point C1 ′ set in step S132 is set to the display position C ′.
In step S138, the lateral movement point C1 ′ is deleted, and the process ends.

On the other hand, in step S139, the lateral movement point C1 ′ is deleted.
In step S140, the vertical movement point C2 ′ set in step S134 is set to the display position C ′.
In step S141, the vertical movement point C2 ′ is deleted, and the process ends.
In step S142, since the priority direction of the transition rule R is “vertical direction”, whether or not the vertical movement point C2 ′ is the end point (upper end or lower end) of the page image of the currently displayed page. To check. If it is an end point, the process proceeds to step S143, and if it is not an end point, the process proceeds to step S140.
The process proceeds to step S140 as described above.

On the other hand, when proceeding to step S143, since the vertical movement point C2 ′ is already the end point of the page and there is no frame in the vertical direction, it is necessary to move the frame to be displayed in the horizontal direction.
Therefore, in step S143, the vertical movement point C2 ′ is deleted, and in step S144, the horizontal movement point C1 ′ is set to the display position C ′ in order to move the frame in the horizontal direction.
In step S145, the lateral movement point C1 ′ is deleted, and the process ends.
The above processing is display position information update processing.
