Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention displays various types of information such as document data and image data in the form of a book in page units.
The present invention relates to a page display method for switching pages and displaying information.

[0002]

2. Description of the Related Art As means for collecting a large amount of document data and image data and extracting necessary information from the data, various information such as document data and image data are displayed on a display screen of an information processing apparatus in page units. There is something. Here, the search for information is performed by switching pages by sequentially or directly displaying pages specified by the user, or by scrolling the pages on the screen. But,
In this method, it is difficult to know which page in the whole is being displayed, and since it is a two-dimensional scroll within a limited display screen, efficiency in searching for information is low. Further, when the page is switched, the display is switched instantaneously, so that it is difficult to say that the display is friendly to the user, for example, it is not possible to immediately recognize that the page has been switched.

[0005] Therefore, a method has been proposed in which a book turning animation (hereinafter, referred to as a page turning animation) is displayed when switching pages by imitating a book that has been familiar to humans. As an example of this,
Performs a projective transformation process on the page during the page turning and combines it with other pages to make the page turning look three-dimensional, giving a visual effect close to turning a book familiar in the real world, Further, there is a feature in which a page turning animation is performed by changing a page turning speed to improve search efficiency. As such a known example, there is a “page turning display control device” disclosed in Japanese Patent Application Laid-Open No. 7-319899.

[0004] As means for improving the search efficiency,
A bookmark is inserted into the page for later reference to a predetermined page that is frequently referred to or important, and at the time of a search, the bookmark is selected (pointed) by an input means, so that the page with the bookmark is inserted. Some open immediately. As such a known example, there is an "information display system having a turning function" disclosed in JP-A-4-21068.

[0005]

The information retrieval method using the conventional page turning animation has the following problems. Especially when turning pages at high speed, there is an individual difference in the response speed, so there is also an individual difference between the issue of the instruction to stop page turning and the position where the page turning is actually stopped. Can be In other words, since there is an individual difference in the speed of the reaction on the user side, for example, even if the user is conscious of performing the operation of stopping page turning when the tenth page is displayed during page turning, actually, For example, a certain user performs a stop operation as soon as the tenth page starts to be displayed, and a certain user performs a stop operation after the tenth page and the eleventh page is displayed. In this case, since both users are aware that the stop operation has been performed on the tenth page, the stop position is finally changed although the stop instruction is issued in the same manner. If the actual stop position has shifted from the desired position at which the user wanted to stop page turning,
Since it is necessary to turn the pages forward or backward by several pages using input means or the like, the search efficiency deteriorates.

[0006] Further, there is the following problem in a method of improving a search efficiency by inserting a bookmark into a location that may be referred to later. The user must explicitly determine whether to insert a bookmark or select a position to insert a bookmark. When it is no longer necessary to refer to the bookmark, the user needs to explicitly remove the bookmark.
Furthermore, bookmarks are sandwiched in page units, and cannot be searched with vague motives such as “this neighborhood”. Further, from the viewpoint of information sharing or personal environment, the search efficiency must be high in the organization unit or the individual unit, but there is no prior art that takes such a point into consideration.

Image) and generates a turn-over correction process 50 to be displayed on the output device 201.

In FIG. 1, a user input 10 is requested for each of the above-mentioned processes as needed.

In the user information detection process 11, when information for identifying the user or the organization to which the user belongs is required for each of the processes, the information is stored in advance in the process data 207 before or during each process. The user information 110 is searched and detected.

In the book generation and display process 30, the appearance of the book, such as the book image, book thickness, and open pages, necessary for book display is generated as book information display data, and the display data is synthesized. , On the output device 201 using the book configuration information 120 and the material data 130 stored in the processing data 207.
Here, each processing data is configured as follows. The book configuration information 120 includes book image information, page order, page number, chapter / section delimiter information, and information (file name, data name, and the like) of document data or image data to be arranged in a page. It is composed of configuration information (such as the arrangement position in the page). The material data 130 is composed of document data or image data arranged in a page.

Each of the display data is generated as follows.

The external appearance of the book is an image such as the cover of the book, and is generated from the book image information in the book configuration information 120. The thickness of the book is determined based on the number of pages and the order of the pages in the book configuration information 120, and the position of the currently opened page is detected from the order of the pages.
The left and right thickness portions of the open book are calculated to generate a thickness image. The open page reads information on document data or image data constituting the page and the respective arrangement information from the book configuration information 120, reads actual document data or image data from the material data 130, and reads It is arranged at a predetermined position and generated.

In the page turning control processing 40, the following processing is performed. First, the speed of page turning, the direction of turning,
At least one of the number of pages to be turned or the degree of detail of the image of the page turning is set as the turning information value using the turning input information 150 stored in the user input 10 or the processing data 207 (turning information value setting 4).
1). Further, the turning page is rotated / deformed using the set turning information value, and the turning image is generated and displayed 42 at the time of turning the page. Here, the turning information 150 is composed of any combination of turning speed, turning direction, turning number, or detail level of image display of page turning. Further, the turning stop detection 43 detects an instruction to stop turning the page, which is input from the user input 10, and performs a turning correction process 50 described later. Here, the detail level of the image display of the page turning (hereinafter, referred to as
The term “detail” is the fineness of the page turning animation, and is expressed, for example, by the number of images displayed when the page is turned. The more the number is, the more detailed animation is displayed. Become.

The turning correction process 50 is a process executed when the user issues a command to stop page turning. For example, the user turns the page slowly in the same direction as the current turning direction and then stops. , Turning the page in the opposite direction to the current turning direction and then stopping, and displaying from the position where the command to stop turning the page is issued until the actual turning of the page is stopped. Thus, the user can reliably display a desired page. Specifically, in the turning correction process 50, the following process is performed. First, in order to correct the position at which the page turning is stopped, at least one of the page turning speed, the turning direction, the number of pages, and the level of detail when turning the page in the current turning direction or the reverse direction is used. The correction value is set using the user input 10 or the turning correction information 160 stored in the processing data 207 (turning correction value setting 51). Further, using the set turning correction value, the turning page is rotated and deformed in the same manner as the turning image generation display 42, and the turning correction image generation display 52 for page turning is performed. Here, the turning correction information 160 is composed of any combination of turning speed, turning direction, turning number, or detail level of image display of the page turning, and for each of the page turning speeds in the page turning control processing 40. Alternatively, it is stored for each speed range. Further, by the turning correction stop detection 53, an instruction to stop the turning correction processing input from the user input 10 is detected,
The current turning correction value is updated, and the turning correction information 160 is updated as necessary. Here, the degree of detail of the turning correction is the fineness of the page turning animation at the time of turning correction, and is expressed, for example, by the number of images displayed when the page is turned, and the larger the number, the more the number of images is displayed. A detailed animation will be displayed.

Next, the flow of processing in this embodiment will be described in detail with reference to FIGS.

FIG. 3 shows the main processing in this embodiment. In step 301, generation of an operation menu, etc.
Initialize processing such as display. In step 30, a book to be described later, such as a book appearance and pages, is generated and displayed (FIG. 4). Next, in step 302, the following processing is performed until a processing end instruction is detected by the user input 10 such as menu selection. That is, when an instruction to turn a page is detected in the displayed book, the page turning control process (FIG. 5) of step 40 is executed.
When the processing end command is detected, the loop 302 is skipped in step 304. Eventually, step 40 is repeated until a loop termination is detected in step 304 after detecting an instruction to end the processing by the user input 10. Finally, in step 305, end processing such as erasing of display data is performed.

Referring to FIG. 4, the book generation and display processing 30 of FIG. 3 will be described. Book generation display processing 30
First, in step 401, a designation of a page to be opened first when a book is displayed is detected by the user input 10, and this is set as an initial value of a page position in book generation in step 404 described later. Here, if there is no designation by the user, it is assumed that there is no page to be opened first, and book generation is performed with the book closed. In step 402, the book configuration information 12
0, refer to the image information of the book such as the cover in the material data 1
The image of the actual book is read from 30. Next, step 4
In 03, the number of pages of the entire book to be displayed is set from the number of pages in the book configuration information 120. Next, in step 404, book generation processing (FIG. 5) is performed to generate book display data. In step 405, the generated display data is synthesized and output device 20
1 is displayed.

Referring to FIG. 5, the book generation processing 404 in the book generation and display processing 30 of FIG. 4 will be described. In the book generation processing 404, in step 501, a page position to be opened when a book is displayed is set. This page position is the position of the page specified and detected in step 401. If the user does not specify the first page to be opened, the page position is set to 0. Next, in step 502, the left and right thickness portions of the opened book are calculated from the set page position and the number of pages of the entire book set in step 403, and a thickness image is generated. Here, the thickness image may be generated by reading a reference thickness image from the material data 130 and deforming the thickness image based on the thickness. Next, if the page position set in step 501 is not 0, that is, if any page is displayed in an open state, in step 503, the document data forming the page from the page configuration information in the book configuration information 120 Alternatively, information on image data and respective arrangement information are read. Then, in step 504, actual document data or image data is read from the material data 130 using the arrangement information, and is arranged at a predetermined position in the page to generate display data of the page. On the other hand, if the page position set in step 501 is 0, that is, if the book is displayed with the book closed, in step 505, the book configuration information 12
Reference is made to information on the cover image data from the image information of the book in 0, and the actual cover image data is read from the material data 130 to generate display data.

Referring to FIG. 6, the page turning control processing 40 of FIG. 3 will be described. Page turning control processing 40
Then, in step 43, the following processing is repeated until a turning stop command is detected. First, when an instruction to turn a page is first given (in the case of “new” in the figure), a page turning information value is set in step 41. Also, when there is a change in the page turning parameter from the user input 10 or the like (in the case of “change” in the figure), the setting of the page turning information value in step 41 is performed.
In step 41, from the user input 10 or the turning information 150, the turning speed, the turning direction, the number of pages turned at one time, or the degree of detail is set as a turning information value which is a parameter for turning the page. Here, the setting of each value may be achieved by a combination of setting means such as acquiring the turning speed and the turning direction from the user input 10 and obtaining the number of turns from the turning information 150. If it is neither "new / change" nor "stop" in the repetition process of step 43 (in the case of "continue" in the figure), the turning image generation and display process of step 42 (FIG. 7) is performed. In short, the page turning information value setting process of step 41 or the turning image generation and display process of step 42 are repeatedly executed until a command to stop page turning is detected from the user input 10. Here, the speed at which the turning image generation and display processing 42 is repeated is determined by the turning speed of the turning information value. For example, if the turning speed is “2 sheets / second”,
The repetitive processing is performed at 0.5 second intervals determined by “1 / (turning speed)”. In step 43, when a page-turning stop command is detected, after performing a page-turning correction process (FIG. 8) in step 50 described later,
The repetition processing of step 43 ends.

Referring to FIG. 7, the turning-over image generation / display processing 42 of FIG. 6 will be described. In the turning image generation / display processing 42, first, in step 701, a page to be turned is set. Here, the page to be turned is determined using the turning direction and the turning number among the turning information values set in step 41. For example, in the case where the turning direction is negative and the number of turns is 5, the setting is made so that five pages are reversed by one turning operation. Next, in step 702, an angle at which a page is rotated and deformed at the time of generating a turning image, which will be described later, is set according to the degree of detail among the turning information values. Next, step 703
In, the page is rotated and deformed based on the angle set in step 702 to generate display data of a turning image. At this time, if the number of turnings set in the step 41 is a plurality of pages, the turning image is generated for the front or last page according to the turning direction, and the thickness image of the turning page group is also generated at the same time. Is done. Next, in step 404,
A book generation process is performed to correct the thickness of a book when turning a page and to generate a display image of a page after the page to be turned. Here, the step 404 is performed as shown in FIG.
Since the book generation processing 404 described above in the book generation and display processing 30 is the same processing (that is, the processing in FIG. 5), the description is omitted. Next, in step 704, the generated roll-up image and the display data of the book are combined and displayed on the output device 201.

Referring to FIG. 8, turn-over correction processing 5 shown in FIG.
0 will be described. In the turning correction process 50, first,
In step 51, a turning correction value setting process is performed. This process corrects the position to stop page turning,
This is a process for setting a parameter for turning a page in the same direction or a direction opposite to the turning direction in the page turning control process 40 as a turning correction value. Specifically, the user input 10 or the turning correction information 160 Then, the turning speed, the turning direction, the number of turning pages, or the level of detail are set as turning correction values that are turning correction parameters. Here, in the case of setting from the turning correction information 160, a turning correction value corresponding to the turning speed is obtained by using the turning speed set in the turning information value setting processing 41 in the page turning control processing 40. (Described later with reference to FIG. 21). In addition, setting of each value of the turning correction value may be performed by a combination of setting means such as turning speed and turning direction from the user input 10 and turning number from turning correction information.

Next, at step 53, user input 1
An instruction to stop page turning from 0 (this instruction is an instruction for instructing the stoppage during the generation and display of a turning correction image, that is, a “turning correction stop instruction”. However, the turning correction stop instruction is the same operation as the turning stop. Until the number of turning pages set by the turning correction value is the same as the number of pages to be turned, and the turning-correction image generating / displaying process of step 52 (FIG. 9), or The processing of updating the turning correction value in step 801 is repeated. In the determination process performed in step 53 of FIG. 8, “stop” means that when the user explicitly issues a page-turning correction stop command to stop page turning from the user input 10, “end” means the generation-display process 52 of turning-corrected image. Is executed by the number of pages set by the turning correction value, "correction value update" is a case where the turning correction value is changed by the user input 10, and "continuation" is a case other than those.

In particular, in the case of "update of correction value", the processing of updating the turning correction value in step 801 is performed. Step 8
In step 01, the turn-over correction information 160 is updated as new correction information, such as the changing speed and the degree of detail, and the processing of repeating step 53 is continued.

As in the case of the page turning control process 40, the speed at which the turn-correction image generation and display process of step 52 is repeated in "continue" is determined by the turning speed of the turning correction value. For example, when the turning speed of the turning correction value is “2 sheets / second”, the repetitive processing is as follows.
It is performed at 0.5 second intervals determined by “1 / (turning speed)”.

In step 53, when a page-turning stop command is detected, that is, in the case of "stop", in step 801 the page-turning correction information 160 is updated with the number of pages turned during correction as new correction information. The repetition processing of step 53 ends. Further, in step 53, if the number of times of turning-corrected image generation and display processing 52 is the same as the number of turning pages set by the turning correction value, "end" is reached, and the repetitive processing of step 53 is ended.

Referring to FIG. 9, the turn-over corrected image generation and display processing 52 of FIG. 8 will be described. In the turning correction image generation / display processing 52, first, in step 901, a page to be turned for correction is set. Here, the page to be turned is determined using the turning direction among the turning correction values set in step 51. Next, in step 902, an angle at which a page is rotated / deformed when a turn-corrected image to be described later is generated is set according to the degree of detail among the turn correction values. Next, in step 903, the page is rotated and deformed based on the angle set in step 902 to generate display data of a turning-corrected image. Next, in step 404, book generation processing is executed to correct the thickness of the book at the time of turning correction and to generate a display image of a page after the turning page. Here, the step 404 is the same processing as the book generation processing 404 described in the book generation and display processing 30 of FIG. 4 (that is, the processing of FIG. 5), and a description thereof will be omitted. Next, in step 904, the generated image data and the display data of the book are combined and displayed on the output device 201.

Specific examples of the page turning control processing 40 and the page turning correction processing 50 will be described below. Here, FIG. 18 shows an example of an operation screen for performing operations related to book display and page turning. In the figure, 1800 is the output device 20
1 shows a page 1801 displayed in 1 and menu buttons for performing a page turning operation. The user can operate buttons 1802 to 1808 on this screen or 180
9 are selected by the input device 202 such as a mouse to give various instructions. In addition, turning information 15
An example of 0 is shown in FIG. 19, turning information 150
Consists of a turning speed table (a), a turning number table (b), and a detail level table (c), and each table indicates a current setting value in addition to each value of the turning speed, the turning number, and the detail level. The selection flag includes a selection flag and a setting flag indicating a value to be selected when there is no designation from the input device 202 at the start of page turning.

It is assumed that the user activates the present system by specifying a book to be displayed and a page to be opened first, and steps 301 and 30 in FIG. 3 are executed to display the screen in FIG. In FIG. 18, when the user presses a button 1806 to start turning a page, step 4 in FIG.
By using 1, the turning speed, the number of pages turned at a time, and the level of detail are obtained from the turning information 150. Here, the turning speed 1902, the turning number 1912, and the detail level 1922 corresponding to 1903, 1913, and 1923 whose setting flags are “1” in each table in FIG. 19 are set as turning information values. At the same time, selection flags 1901, 191 corresponding to these values
"1" is set to 1,1921, and "0" is set to the other selection flags, so that the current setting value can be known from the selection flags.

Here, the direction of turning the page is as follows.
Since the table is not prepared in FIG. 19, the user is requested to determine the direction by the input device 202,
On the other hand, when the user presses one of the operation buttons 1802 arranged on the left and right on the screen, the turning information value is set so that the page is turned in the pressed direction. Assuming that the button 1802 on the left side of the screen is now pressed, the turning information value is turning speed “0.5”, turning number “1”, detail level “3”, and turning direction “left (negative)”. Is set.

Next, in the turning image generation / display processing 42 shown in FIGS. 6 and 7, in step 701, a page to be turned is set. Here, the page to be turned is the page 1801 on the right side in FIG. 18 based on the turning direction and the turning number of the turning information value. Next, in step 702, an angle at which a page is rotated or deformed when generating a flip image is set according to the degree of detail among the flip information values. Here, the setting of the angle is shown in FIG.
Is performed as shown in FIG. In this example, the detail level is “3”.
Thus, the animation during the turning is composed of three images. The rotation / deformation angle for generating each image is determined by the page turning start position 200.
From 1 to the end position 2005 (180
Is distributed at equal intervals according to the number of images to be displayed, so that θ = 180 / (the number of images + 1). In this example, since the image is divided into four equal parts as shown in FIG. 20, the first image rotation angle is 45 degrees, and an image at the position 2002 in the figure is generated. Thereafter, the turning-over image generation display processing 42 during the repetition processing of step 43 corresponds to the 90-degree position 2003, the 135-degree position 2004, and the 180-degree position 2005.
(FIG. 7). In this way, the turning image generation and display process 42 is repeated, and pages are sequentially turned on the display screen.

Next, when the user presses the operation buttons 1803 to 1805 on the display screen during the page turning, the turning information value at the time of page turning is reset.
For example, when the “fast” button of the operation buttons 1803 for changing the turning speed is pressed, in the processing step 41 of FIG. 6, the turning speed in the turning speed table of FIG. The turning speed having a value one step higher is selected, and the selection flag corresponding to the turning speed is set to “1” (the selection flag of the previous turning speed is reset from “1” to “0”). Accordingly, the time interval for performing the repetitive processing step 43 during the page turning control processing is set to “1 / (the newly selected speed)” using the newly selected speed. Also, if “less” is pressed among the operation buttons 1804 for changing the number of pages to be turned, in the processing step 41 of FIG. A turn number one step smaller is selected, a selection flag corresponding to the turn number is set to “1” (the previous turn number selection flag is reset from “1” to “0”), and step 7 is performed.
At 01, a target for generating a turning image is reset. Further, when the “fine” button among the operation buttons 1805 for changing the level of detail is pressed, in the processing step 41 of FIG. 6, in the level of detail table of FIG.
The level of detail one level higher (larger value) than the currently selected level of detail is selected, and the selection flag corresponding to the level of detail is set to “1” (the selection flag of the previous level of detail is “ Is reset from "1" to "0"), step 702
, A turning image is generated by setting the turning angle again to θ = 180 / (the number of newly selected images + 1).

When a page is turned under the same turning information value for a certain period of time, or when the operation button 1808 is pressed, the current settings are saved in FIG.
(B) The setting flag corresponding to the place where the selection flag is "1" in each table in (c) is set to "1", and is used as a specified value of the turning information value in the next page turning.

When the operation button 1807 for stopping the page turning is pressed during the page turning (that is, the detection of the command to stop the page turning), the processing step 43 for repeatedly turning the page is stopped in FIG. (FIG. 8) is performed. Here, an example of the turning correction information 160 is shown in FIG. In FIG. 21, the turning correction information 160 is a lower limit 2 of the turning speed indicating a range of the turning speed when the page is turned before the turning stop command is detected.
101, the upper limit 2102, and the turning speed 2103, the turning direction 2104, the turning number 2105, which are the page turning parameters used in the turning correction process.
And the degree of detail 2106. Where turning direction 2
The value indicated by 104 is “positive” or “negative”, which is “positive” when turning in the same direction at the time of turning correction with respect to the turning direction before stopping, and “negative” when the turning is opposite. The number of turns 2105 is the number of pages to be turned for correction, and indicates that turning is performed after turning over the number of pages one by one.

In the present embodiment, when the stop button 1807 is pressed during the page turning (turning stop command), FIG.
In step 51, the turning speed "0.
5 "is detected, and a turning correction value corresponding to the turning speed is set. Specifically, since the turning speed is “0.5”, each value corresponding to the row having the lower limit of the turning speed of 0.5 and the upper limit of 0.99 from FIG. 21 is selected as the turning correction value. Here, the turning speed is “0.75”, the turning direction is the same as that of the page turning, the number of pages to be turned for correction (that is, the number of pages to be turned before completely stopping page turning) is “2”, and details. The degree is set to “3” as in the case of turning the page. Processing Step 52 for Generating and Displaying a Turnover Corrected Image (FIGS. 8 and 9)
This is to generate and display an animation for turning pages in the same manner as in the case where the number of turning pages at a time is set to 1 in the turning image generation and display process 42 in the page turning control process.

When the user presses the operation buttons 1803 to 1805 on the display screen during the turning correction, the turning correction value for turning correction is reset, and the turning correction information is updated. For example, when the “fast” button of the operation buttons 1803 for changing the turning speed is pressed, in the processing step 801 of FIG. 8, a value one step higher than the turning speed currently selected in the turning correction information of FIG. The turning speed is selected from the turning speed table shown in FIG. 19A, and the new turning speed is updated as the turning speed 2103 for the corresponding turning correction, and the turning correction information is updated. Accordingly, the time interval for performing the repetitive processing step 53 during the turning correction control processing is set to “1 / (newly selected speed)” using the newly selected speed. In this example, FIG.
Although the turning speed is obtained by one step higher or one step lower by referring to the table of (a), a predetermined value may be added to or subtracted from the value of the turning speed. When the “fine” button is pressed among the operation buttons 1805 for changing the level of detail, in the processing step 801 of FIG. 8, the level of detail one step higher than the level of detail currently selected in the turning correction information of FIG. A high (large value) detail level is selected from the detail level table of FIG. 19C, and the value of the newly selected detail level is updated as the detail level 2106 at the time of the corresponding turning correction, and the turning correction information is updated. , Step 9
In 02, the turning angle is set again as θ = 180 / (the number of newly selected images + 1), and a turning-corrected image is generated. Furthermore, an operation button 1 for specifying a turning direction
When a button opposite to the current turning direction is pressed out of the turning direction 802, the corresponding part of the turning direction 2104 in the turning correction information is “negative” if “positive” and “negative” The value is updated to “correct”, and the turn-over corrected image generation and display process is repeatedly performed based on this value.

When the stop button 1807 is pressed in the turning correction display screen (detection of a turning correction stop command), the number of pages turned up to now for correction is stored as the currently selected turning number 2105. Then, the turning correction process ends.

According to the first embodiment, when the stop button is pressed in the middle of a page turning operation, the turning-over correction process starts. For example, a predetermined page is displayed as the turning-over correction information at a speed slightly lower than the previous turning speed. If the setting is made to stop after that, the turning-off correction display is made by the setting after the stop button is pressed, and then the stop is performed.
Therefore, search efficiency when searching for a desired page desired by the user is improved. In particular, when the stop button is pressed during the display of the turning correction, the turning is stopped at that point, so the user is instructed to stop when the page turning is performed at a slightly slower speed in the turning correction display. It can be done and any user can easily stop at the desired page (regardless of the slow individual response). In addition, when the stop button is pressed or the turning correction value is updated while the turning correction is being displayed, the turning correction information is updated.
Next, when the user turns the page and presses the stop button to start the turning correction process, a turning-corrected image is generated and displayed using the updated turning correction information. Therefore, since the turning correction is performed in accordance with the user's sense, the search efficiency is further improved. Also, since the turning correction information uses the turning correction information in accordance with the turning speed before the stop button is pressed to enter the turning correction display, for example, when the turning speed is fast, the turning correction display is relatively fast and the turning speed is slow. It is possible to make an adjustment such that the turning correction display is sometimes slow. Further, in the first embodiment, when the user changes the turning information value during the page turning display, the change is written into the page turning information 150, and similarly, the turning correction value by the user during the turning correction display. When a change is made, the change is turned over and written into the correction information 160. Therefore, if the user changes the information several times, a user-friendly setting can be obtained, and the search efficiency after that can be improved. There is an effect of improving.

According to the third embodiment, the first embodiment
In addition to the effects of the first embodiment, since the turning correction information is prepared for each user or each organization to which the user belongs, an information search environment can be realized for each user or each organization to which the user belongs.

Next, a fourth embodiment of the present invention will be described. The basic configuration of an apparatus for realizing the page display method according to the fourth embodiment is the same as in FIG.

FIG. 10 shows an outline of the processing of this embodiment.
In the figure, the processes and data having the same numbers as those in FIG. 1 showing the outline of the processes of the first to third embodiments of the present invention also indicate the same processes and data in the present embodiment.

The processing according to the present embodiment includes a user information detecting process 11 for detecting information about a user from the user information 110 using the user input 10 from the input device 202 as an auxiliary input, if necessary, a book image, a book thickness, And an image in a page generated as a book form and output device 201
Generation and display processing 60 for generating and displaying book information to be displayed, reference monitoring processing 70 for determining whether or not a page of the displayed book is in a reference state, and turning pages of the displayed book Image to turn the page by setting the page turning parameter (turning image)
Page turning control processing 80 to be displayed on the output device 201, and when a command to stop page turning is detected, a turning correction value is set in order to correct the page turning stop position, and the page is set. It comprises a turning correction process 50 for generating a turning image (turn-correction image) and displaying it on the output device 201.

The user input 10 is requested for each of the above processes as required.

The user information detection process 11 includes a process for storing, in advance of or during each process, the process data 207 when information for identifying the user or the organization to which the user belongs is required. Search user information 110
To detect.

In the book generation and display processing 60, the appearance of a book such as a book image, book thickness, and open pages necessary for book display is generated as book information display data, and the display data is synthesized. The processing to be displayed on the output device 201 is performed using the book configuration information 120 and the material data 130 stored in the processing data 207. Further, a process 61 for generating display data of a reference marker that visually indicates the frequency of reference to a group of pages in the book is performed using the reference frequency information 140 stored in the processing data 207.

Here, each processing data is configured as follows. The book configuration information 120 includes book image information, page order, page number, chapter / section delimiter information, and information on document data or image data to be arranged in the page and its arrangement configuration information. The material data 130 is composed of document data or image data arranged in a page. The reference frequency information 140 includes a reference frequency for each continuous page group of one or more pages or for each section based on the section information of the chapter in the book configuration information 120, and includes information such as a reference date and time and a reference frequency.

Each of the display data is generated as follows.

The external appearance of the book is an image such as the cover of the book, and is generated from the book image information in the book configuration information 120. The thickness of the book is determined based on the number of pages and the order of the pages in the book configuration information 120, and the position of the currently opened page is detected from the order of the pages.
The left and right thickness portions of the open book are calculated to generate a thickness image. The open page reads information on document data or image data constituting the page and the respective arrangement information from the book configuration information 120, reads actual document data or image data from the material data 130, and reads It is arranged at a predetermined position and generated.

In the reference marker generation processing 61, the reference frequency for the page group in the book is searched using the reference frequency information 140, and the display data of the reference marker is generated according to each reference frequency. The reference marker is a mark that visually represents the reference frequency of a predetermined page group.

In the reference monitoring process 70, it is determined whether or not the book page displayed in the book generation and display process 60 is in a reference state. When in the reference state, the reference frequency for the page, the page group to which the page belongs, or the section to which the page belongs is updated and stored in the reference frequency information 140.

In the page turning control processing 80, the following processing is performed. First, the speed of page turning, the direction of turning,
At least one of the number of pages to be turned or the degree of detail of image display of the page turning is set as a turning information value as the turning information 1 stored in the user input 10 or the processing data 207.
The setting is made using 50 or the reference marker turning information 170 (turning information value setting 81). In particular, when the turning page is within the range of the reference marker, the turning information value is set using the user input 10 or the reference marker turning information 170. If the turning page is not within the range of the reference marker, the turning information value is set using the user input 10 or the turning information 150. Here, the detail level of the image display of the page turning (hereinafter, referred to as the detail level) is the fineness of the page turning animation, and is represented by, for example, the number of images displayed when the page is turned. As this number increases, a more detailed animation is displayed. Further, the turning page is rotated / deformed using the set turning information value, and a turning image generation display 82 at the time of turning the page is performed. Here, the turning information 150 is composed of any combination of turning speed, turning direction, number of turns, or detail. The reference marker turnover information 170 includes a reference frequency or a combination of arbitrary information among a turnover speed, a turnover direction, a turnover number, or a detail level for each range of the reference frequency. Further, a turn stop detection 83 detects a command to stop turning the page, which is input from the user input 10, and performs a turn correction process 50 described later.

In the page turning correction process 50, the page turning speed, the turning direction, the number of pages, or the degree of detail when the page is turned in the current turning direction or the opposite direction is corrected in order to correct the position where the page turning is stopped. At least one of them as the turning correction value, the turning correction information 160 stored in the user input 10 or the processing data 207.
(Turning correction value setting 51). Further, using the set turning correction value, the turning page is rotated and deformed in the same manner as the above-described page turning image generation display 82, and the turning display image generation display 52 at the time of page turning is performed. Here, the turning correction information 160
Is a combination of arbitrary information among the turning speed, the turning direction, the number of turns, and the degree of detail, and is stored for each page turning speed or each speed range in the page turning control processing 80. Further, the turning correction stop detection 53 detects a command to stop the turning correction processing input from the user input 10, updates the current turning correction value, and updates the turning correction information 160 as necessary.

Next, the flow of processing in this embodiment will be described in detail with reference to FIGS.

FIG. 11 shows the main processing in this embodiment. In step 1101, processing such as generation and display of an operation menu is initialized. Step 60
Then, a book generation display (FIG. 12), which will be described later, such as the book appearance and pages, is performed. Next, in step 1102,
The following processing is repeated until a processing end instruction is detected. First, in step 70, reference monitoring processing (FIG. 14) is performed.
In this process, a page in the book displayed in step 60 or a page turning control process 80 described later
It is monitored whether or not the page turned over and stopped and opened is in a reference state. Next, when an instruction to turn pages is detected for the displayed book by user input 10 such as menu selection, a page turning control process 80 (FIG. 15) described later is executed. If the processing end instruction is detected, the loop processing 1102 is skipped in step 1104. Eventually, Steps 70 and 80 are repeated until the loop 1102 ends in Step 1104 after the processing end command is detected by the user input 10. Finally, in step 1105, end processing such as erasing of display data is performed.

Referring to FIG. 12, the book generation and display processing 60 of FIG. 11 will be described. In the book generation / display processing 60, first, in step 1201, the designation of the page to be opened first when the book is displayed is detected by the user input 10, and this is set to the initial value of the page position in book generation in step 1204 described later. I do. here,
If there is no designation by the user, it is assumed that there is no page that can be opened first, and book generation is performed with the book closed. In step 1202, an actual book image is read from the material data 130 with reference to book image information such as a cover in the book configuration information 120. next,
In step 1203, the number of pages of the entire book to be displayed is set based on the number of pages in the book configuration information 120. Next, in step 1204, book generation processing (FIG. 13) is performed to generate book display data.
In step 1205, the generated display data is combined and displayed on the output device 201.

The book generation processing 1204 in the book generation and display processing 60 of FIG. 12 will be described with reference to FIG. In the book generation processing 1204, step 13
In 01, a page position to be opened when a book is displayed is set. This page position is determined by the step 12
01 is the position of the page specified and detected. If the user does not specify the first page to be opened, the page position is set to 0. Next, step 1302
In the above, the set page position and the step 1
From the number of pages of the entire book set in 203, the left and right thickness portions of the opened book are calculated, and a thickness image is generated. Here, the thickness image may be generated by reading a reference thickness image from the material data 130 and deforming the thickness image based on the thickness. Next, in step 1303, the reference frequency related to the page group or the section of the book to be currently displayed is read from the reference frequency information 140. Next, at step 61, based on the read reference frequency information, display data of a reference marker that visually indicates the reference frequency is generated. Here, an image serving as a reference for displaying a reference marker is read from the material data 130, and an image is generated in which the length is changed according to the reference frequency and the thickness is changed according to the number of pages related to the reference frequency. In this case, the reference marker is displayed on the thickness portion of the book. In addition, the color or the image may be changed according to the reference frequency.

Next, the page position set in step 1301 is determined. If the page position set in step 1301 is not 0, that is, if any page is opened and displayed, step 13
At step 05, information on document data or image data constituting a page is read from the page configuration information in the book configuration information 120, and respective arrangement information. Then, in step 1306, actual document data or image data is read from the material data 130 using the arrangement information, and arranged at a predetermined position in the page to generate display data of the page. On the other hand, if the page position set in step 1301 is 0, that is, if the book is displayed with the book closed, in step 1307, the book image information in the book configuration information 120
Refer to the information related to the cover image data, and select the material data 1
30. The actual cover image data is read from 30 to generate display data.

FIG. 23 shows the generation and display processing 60 of the book.
15 shows an example of the reference frequency information 140 read in step 1303 of FIG. In the figure, the reference frequency information includes target page / page group / chapter / section delimiter information 2301, the number of times 2303 they were referenced, and a reference date / time set 2303 as a reference history. In addition, reference frequency information 1
Reference numeral 40 is prepared in the processing data 207 for each book in advance. Initially, when the reference frequency information 140 is first created, information demarcated for each chapter of the book is stored as page / page group / chapter section delimitation information 2301, the number of references 2302 is set to 0, and the reference date and time are set. Is left blank. Instead of dividing by chapters, they may be divided by predetermined pages. Further, the user may be allowed to change the setting of the page group dividing method. Further, when creating the reference frequency information 140 for a page group that the user considers to be an important page from the beginning, the reference frequency 23
It is also possible to set a predetermined value other than 0 as 02 (meaning that the frequency of reference to an important page is increased from the beginning).

Based on the reference frequency information as shown in FIG. 23, in the above-mentioned step 61, the reference image is read from the material data 130, and the length is set according to the reference frequency to the number of pages related to the reference frequency. Display data of an image whose thickness is changed accordingly is generated, and displayed on the thickness portion of the book as a reference marker that visually indicates the reference frequency. FIG. 24 shows the relationship between the reference image and the generated reference marker. Image 2401 serving as a reference in the figure
Is an image of a reference marker whose reference count is 10 times and whose target is equivalent to 10 pages. On the basis of this, the reference markers are referred to as “reference marker thickness = reference image thickness × (number of target pages / reference page number)” and “reference marker length = reference image thickness” × (reference frequency / reference frequency of reference) ”. Image 2 of reference marker in FIG. 24
Reference numerals 402 to 2404 denote each part 2311 to 2 in FIG.
313 is an image of a reference marker generated corresponding to 313.
The reference marker generated in this manner is displayed after being deformed in accordance with the book angle and the like when combined with the book thickness and page display data in step 1205 of FIG.

FIG. 17 shows an example of a book display screen displayed in this example. In the figure, 1701 and 1702
Is a page in which document data and image data are arranged in processing steps 1305 and 1306. Also, 17
03 and 1704 are the thickness portions of the book generated in the processing step 1302. 1705, 1706
Reference numerals 1707 and 1707 denote examples in which the reference markers 2402 to 2404 generated in the processing steps 1303 and 61 are deformed in accordance with the display angle of the book, and are displayed on the left, right, and lower parts of the book.

Referring to FIG. 14, the reference monitoring process 70 of FIG. 11 will be described. In the reference monitoring process 70, in step 1401, a determination time for determining a reference state is initialized, and a reference page serving as monitoring information and a timer for counting the reference time are also initialized. In the initial setting of the monitoring information, a currently opened page is set as a reference page. In addition, it is assumed that the determination time can be initially set by a user input 10. Here, only when this reference monitoring processing 70 is executed for the first time, step 14
01 is to be initialized.

After step 1401, the currently opened page and the reference page in the monitoring information are compared to determine whether or not they match. If the currently opened page is different from the reference page in the monitoring information, it is determined that the page is turned by the page turning control processing 80 described later, and in step 1402, the reference page in the monitoring information is changed to the current page. The page is updated, the timer for counting the reference time is reset, and the process ends. If the currently opened page is the same as the reference page in the monitoring information, the timer in the monitoring information is compared with the determination time (the value set in step 1401 for determining the reference state). If the value of the timer exceeds the determination time, it is determined that the page has been referred to because the user has displayed the page for a time longer than the determination time, and the reference frequency information 140 is updated in step 1403. The process ends. In the update processing of the reference frequency information in step 1403, first, information on a page group to which the page belongs and a break is searched from the book configuration information 120 based on the corresponding page. Next, the reference frequency for the corresponding page, page group, or break in the reference frequency information 140 is created and updated using the searched information. For example, in the example of the reference frequency in FIG. 23, the page / page group / separation information 2301 to which the current page belongs is searched, the corresponding reference count 2302 column is counted up, and the corresponding reference date / time 2303 column is displayed. Record the date and time. In the comparison between the timer and the determination time,
If the value of the timer is shorter than the determination time, it is determined that no reference is made, and the process ends.

As another example of the reference judging process in the reference monitoring process 70, a command indicating the reference is issued to the currently opened page by user input 10 such as menu selection. The instruction may be detected.

Referring to FIG. 15, the page turning control processing 80 of FIG. 11 will be described. In the page turning control processing 80, first, in step 81, the user input 10
Alternatively, from the turning information 150 and the reference marker turning information 170, the page turning speed for each of the page on which the reference marker is displayed and the other pages,
The turning direction, the number of pages turned at a time, or the level of detail is set as a turning information value which is a parameter for turning a page. Note that the turning information value setting processing does not set the turning information value as a parameter used in the turning image generation display 82 described later, but includes a turning information value for a page on which a reference marker is displayed, and
The other page turning information values are set in predetermined work areas. The process of actually setting the turning information value as a parameter used in the turning image generation display 82 is described in Step 1 described later.
503 and 1504. Further, setting of each value of the turning information value to be set in the work area is, for example, obtaining the turning speed and the turning direction from the user input 10, and obtaining the number of turns from the turning information 150 or the reference marker turning information 170. May be combined with setting means.

Next, at step 83, user input 1
The following processing is repeated until an instruction to stop page turning is detected from 0. First, in step 1502, the reference frequency of the currently turned page is detected by searching the reference frequency information 140. Next, the page to be turned is
It is determined whether or not the page has a reference marker. If it is the reference marker portion, in step 1503, the turning information value of the reference marker portion set in the work area in step 81 is searched, and
Is set as a page turning information value which is a parameter for the following page turning. If the page to be turned is not the reference marker portion, in step 1504, the page turning parameter is set using the page turning information value other than the reference marker set in the work area in step 81. Set (reset) the turning information value. Steps 1503 and 1504 above
When the turning target page has a reference marker, the turning information value according to the reference frequency is set, and when the turning target page does not have the reference marker, the turning information value that is normally used is set. Next, it is determined whether an instruction to stop turning the page is detected by the user. If the page-turning stop instruction is not detected, it is determined that the page-turning is to be continued, and in step 82, the page-turning image generation / display processing (FIG. 16) is executed. Here, the speed at which the turning image generation and display processing is repeated is determined in step 150.
3, 1504, which is determined by the turning speed of the turning information value. For example, when the turning speed is “2 sheets / sec”, the above-described repetitive processing is performed at 0.5 second intervals obtained by “1 / (turning speed)”. on the other hand,
If a page-turning stop command is detected, step 50
After executing the turning correction process, the repetition process of step 83 is ended.

Here, the turning information 150 is an example of the turning information 150 of the first embodiment of the present invention shown in FIG.
Are the same as those described in the above, and the details are omitted here. FIG. 25 shows reference marker turning information 170 used as the turning information value of the reference marker portion.
Here is an example. In the figure, the reference marker turning information 170 includes a reference frequency or a reference frequency range 2501, and a turning speed 250 when turning a page of a portion matching the reference frequency.
2, consisting of the number of turns 2503 and the degree of detail 2504. For example, if the current page to be turned is “17 pages”, in step 1502, the reference frequency information 14
Search for 0. According to the example of the reference frequency information 140 in FIG. 23, the page is a page belonging to one chapter, and the reference frequency 2
It is detected that the reference marker portion is 0. Next, since the page to be turned is the reference marker portion, step 15
In step 03, the reference marker turning information 170 is searched to obtain turning information that matches the detected reference frequency (reference count). According to the example of the reference marker turning information 170 in FIG. 25, the reference frequency matches the reference frequency in the range of “11 to 20”, and therefore, the corresponding turning speed “1.
0 ", the number of turns" 1.0 ", and the detail level" 4.0 ".
This is set as a turning information value which is a page turning parameter. Also, here, in the turning information value, FIG.
The turning direction which is not determined by the example of the reference marker turning information 170 of the above is set as the same direction as the turning direction at present.

In the turning image generation / display processing 82, first, in step 1601, a page to be turned is set. Here, the page to be turned is determined in step 81 using the turning direction and the turning number among the turning information values set. For example, if the turning direction is negative and the number of turns is 5,
The setting is made so that five pages are reversed by one turning operation. Next, in step 1602, an angle at which a page is rotated / deformed when a turning image to be described later is generated is set according to the degree of detail among the turning information values. Here, the setting of the angle has already been described with reference to FIG.

Next, in step 1603, the page is rotated / deformed based on the angle set in step 1602, and the display data of the turning image is generated. At this time, if the number of turnings set in step 1503 or 1504 is a plurality of pages, the turning image is generated for the front or last page according to the turning direction, and the thickness image of the turning page group is simultaneously set. Is also generated. Next, in step 1204, a book generation process is performed to correct the thickness of the book when turning a page and to generate a display image of a page after the page to be turned. Here, the step 1204
Is the same process as the book generation process 1204 described in the book generation and display process 60 of FIG. Next, in step 1604, the generated roll-up image and the display data of the book are combined and displayed on the output device 201.
