Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention divides a data file into two-dimensional areas (hereinafter referred to as pages) like a document creation data processing device, a drawing design data processing device, and the like. More particularly, the present invention relates to a page turning method for shifting a page to be displayed on a screen one page at a time in a certain direction in a data file.

[Conventional technology]

Heretofore, there have been the following two methods of this type of page turning method.

The first method is a method for performing page turning for one screen without fail when there is a page turning request.

In the second method, for example, it is checked whether or not a page turning request has been issued immediately before outputting a display unit. If there is a page turning request, the output of the subsequent display unit is stopped in the page being displayed and the next page is output. The process of starting the output of the display unit, outputting the next display unit if there is no page turning request, and checking again whether there is a page turning request for the page being processed for screen output until the page display of the page is completed. It is a method of repeating. As a display unit, for example, a row is often used in a document creation data processing device.

[Problems to be solved by the invention]

The conventional page turning method described above is different from the first method in that
Since the page turning speed is suppressed to the screen display speed, if the number of pages in the data file is large and searching for a needle from a straw pile or if the screen display speed is slower than the visual response speed However, there is a disadvantage that it takes too much time to turn pages and is not suitable.

Further, in the second method, the shape of the display unit depends on the physical display order which is not related to human visual appearance. For example, in the case of a document creation data processing device, the display unit is usually 1 unit. Since the page is line-by-line, the feature of the page may not always be at or near the first line, but may be at the bottom of the screen. (When a page is repeated with a page number, the page number is displayed on the bottom line. Often has the disadvantage of not being suitable in such cases. Further, when it is determined whether there is a page turning request immediately before screen display, there is a disadvantage that several pages are skipped at once.

Further, in both the first method and the second method, a time delay occurs between the page turning request and the screen display. Therefore, for example, in the document creation data processing device, the page turning operation is performed on the keyboard. In the case where it is realized by hitting a certain key, the disadvantage is that even if you stop pressing the key when you reach the target page on the screen, the screen will go too far by the key pressed during the delay time is there.

By the way, when we look for a description of a document that has already been written in real life, we turn pages by hand with the content of the document in mind. At this time, if the relative position in the page of the content of the document to be searched is known, the user tries to turn the page while keeping an eye on the position. Therefore, when an interface closer to a page turning process when a person turns a normal document is realized in the data processing device, a part or all of the page is displayed on the screen instead of displaying the entire page on the screen. It is desirable to set an area for displaying the data (hereinafter referred to as a page turning area) to improve the page turning speed. Also, when performing page turning with the eye on the relative position within the page as described above, if the speed of page turning is high, the field of view of the human eye narrows almost concentrically in accordance with it. When the visual field of the human eye becomes smaller than a certain level, it becomes insufficient to judge the content of data, and the state becomes indistinguishable. Therefore, in such a case, it is better to set the lower limit value in consideration of the shape to the size of the page turning area corresponding to the field of view of the human eye, so as not to fall below the lower limit value.

In addition, even if the page turning does not completely operate in real time by a key operation, the completion time of the screen output process is estimated so as to be closer to the actual time, and another operation can be performed until the estimated completion time. Makes sense. This is because even if there is an error in the calculation of the estimated completion time, and there is a discrepancy between the actual completion time of the screen output processing and the expected completion time of the screen output processing, the key input of the page turning request is performed for a while. This is because it is much easier for the user to use it than to look at the page turning process that has gone too far.

Furthermore, it is better not to skip pages as is often the case when operating by hand, but when dealing with a large amount of data in a data file, it may be more convenient to have a thinning function. For example, when repeating pages of a document having similar characteristics over a plurality of pages, for example, when repeating a dictionary or the like, it is desirable to appropriately skip pages by successively pressing keys that require page turning. It is easy to search for data.

Therefore, it is desirable that some modes can be selected according to the situation where the user is placed.

In view of the above, an object of the present invention is to provide a thinning mode in which pages are skipped, a reduced mode in which the contents of a page are displayed only in a page turning area, and a reduced mode in which the thinning mode and the reduced mode are combined. It is an object of the present invention to provide a page turning method which enables selection and provides an interface closer to a page turning process when a person turns a normal document to a data processing apparatus.

[Means for solving the problem]

A page turning method according to the present invention is a data processing apparatus that divides a data file into a plurality of pages and displays data in units of pages on a screen for interactive processing. Calculates the screen output required time based on the information that affects the delay time such as the size of the screen display buffer and the amount of data to be output and displayed A completion time calculating means for calculating an estimated completion time by adding the current time obtained by the current time obtaining means and setting the estimated completion time in the estimated completion time storage means; and a final page turning request accumulated during the screen output processing. A thinning mode in which only the corresponding page is displayed and no intermediate pages are displayed, and the number decreases as the number of page turning requests issued in succession increases. Between the reduced mode in which data is displayed only in the page turning area of a certain size and the reduced mode in which the page turning area is smaller than the minimum size when the page turning area is larger than a certain minimum size and the reduced size mode in which the page size is smaller than the minimum size and in the thinning mode. A page turning mode instructing means for providing an indicating mechanism of any one of the page turning mode and the page turning mode, and setting the designated page turning mode in the page turning mode storing means; and providing a page turning instruction mechanism for requesting the page turning. Each time the page counter is incremented, a page counter instructing unit that increments the call counter, a call counter reset unit that resets the call counter, and a current time obtained by the current time acquiring unit that is passed control from the page counter instruction unit. If the estimated completion time set in the time storage means has not passed, When the page counter is updated and control is returned to the caller, and the current time has passed the estimated completion time, the page repetition execution determining means for resetting the relative page counter and control is passed from the page repetition execution determining means In the thinning mode, the entire screen is determined as a page turning area, and the page number of the page to be displayed is calculated by adding the value of the relative page counter to the page number of the most recently displayed page. If so, the size of the page turning area is calculated based on the value of the call counter, the position of the page turning area is obtained by the page turning area origin obtaining means, and the page number of the latest displayed page is updated and displayed. Calculate the size of the page turning area based on the value of the call counter in the degenerate thinning mode. When the size becomes smaller than the minimum size, the page size is set to the minimum size and the position of the page turning area is obtained by the page turning area origin obtaining means, and the page number of the latest displayed page is added to the value of the relative page counter and displayed. The page number of the page to be calculated is calculated, and when called from the call counter reset unit, the entire screen is determined as a page turning area, and the page number of the latest displayed page is set as the page number of the page to be displayed, A page turning area determining means for causing the estimated completion time storing means to establish an estimated completion time by the completion time calculating means, and a position and size of the page turning area and a page number determined by the page turning area determining means. Display the data of the page to be displayed in the data file only in the page turning area on the screen And a screen display means.

[Action]

In the page turning method of the present invention, the current time obtaining means obtains the current time, the page turning area origin obtaining means obtains the position of the page turning area on the screen, and the completion time calculating means obtains the delay such as the size of the screen display buffer. The screen output required time is calculated based on the information affecting the time and the data amount to be output and displayed, and the estimated time is calculated by adding the required time to the current time obtained by the current time obtaining means. A thinning mode in which the page turning mode instruction means displays only the page corresponding to the last request of the page turning request accumulated during the screen output process and does not display the middle page, and a page issued continuously. A degraded mode in which data is displayed only in a page turning area whose size decreases as the number of page turning requests increases, and a page turning area exceeding the minimum size When the size is smaller than or equal to the minimum size, when the size is smaller than or equal to the minimum size, a mechanism for indicating a page turning mode of one of the reduced mode and the reduced mode, which is the thinning mode, is provided, and the specified page turning mode is turned. Set in the mode storage means, the page turning instruction means provides a page turning instruction mechanism, and updates the call counter each time page turning is requested; the call counter reset means resets the call counter; If the control is passed from the page turning instruction means and the current time obtained by the current time acquisition means does not exceed the estimated completion time set in the completion time storage means, the relative page counter is updated and control is returned to the calling source and the current time is returned. If the time has passed the estimated completion time, reset the relative page counter and determine the page turning area If the column is given control from the page turning execution determination means, the entire screen is determined as a page turning area in the thinning mode, and the value of the relative page counter is added to the page number of the most recently displayed page. The page number of the page to be displayed is calculated, and in the degraded mode, the size of the page turning area is calculated based on the value of the calling counter, and the page turning area origin obtaining means obtains the position of the page turning area and displays the page latest. The page number of the page to be updated is set as the page number of the page to be displayed, and in the reduced-thinning mode, the size of the page turning area is calculated based on the value of the call counter. Using the page turning area origin acquisition means as the size, obtain the position of the page turning area and add it to the page number of the latest displayed page. Calculate the page number of the page to be displayed taking into account the value of the relative page counter, and when called from the call counter resetting means, determine the entire screen as a page turning area and change the page number of the page displayed most recently. The page number to be displayed is set as the page number, the completion time calculating means sets the estimated completion time in the estimated completion time storage means, and the screen display means determines the position and size of the page turning area and the page number determined by the page turning area determining means. , The data of the page to be displayed in the data file is displayed only in the page turning area on the screen.

〔Example〕

Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing a configuration of a page turning subroutine 10 to which a page turning method according to an embodiment of the present invention is applied. The page turning subroutine 10 is incorporated in a document creation data processing device (not shown), and includes a page turning mode instructing unit 11, a page turning instructing unit 12, a call counter reset unit 13, a page turning mode, Storage means 14 and page turning execution determination means 15
Estimated completion time storage means 16, call counter 17,
It comprises a relative page counter 18, a completion time calculating means 19, a page turning area determining means 20, a current time obtaining means 21, a screen displaying means 22, and a page turning area origin obtaining means 23.

Page turning mode instructing means 11, page turning instructing means 12
The call counter reset means 13 controls an interface called from another module in the document creation data processing device, and the current time obtaining means 21, the screen display means 22, and the page turning area origin obtaining means 23 include an operating system and hardware. Controls the interface.

In the page turning mode storage means 14, the thinning mode in which only the page corresponding to the last request of the page turning request accumulated during the screen output processing of the page is displayed and the intermediate page is not displayed, A reduced mode in which data is displayed only in a page turning area having a size that decreases as the number of page turning requests increases, and a reduced mode in which the page turning area becomes smaller than the minimum size when the page turning area exceeds a certain minimum size. Any one of the page turning modes of the reduced mode and the reduced mode, which is the reduced mode, is held.

The estimated time completion time storage means 16 holds the estimated completion time of the screen output processing of the page.

The call counter 17 holds the number of times the page turning instruction unit 12 is called continuously during the page screen output process.

The relative page counter 18 holds the number of page turning requests accumulated during the screen output processing of the page.

Next, the operation of the page turning method according to the present embodiment configured as described above will be described.

The calling module that uses the page turning subroutine 10 first calls the page turning mode instructing means 11.

The page turning mode instructing means 11 sets the page turning mode of the thinning mode, the reduced mode or the reduced thinning mode specified by the calling module to the page repeating mode storage means 14 and sets the page changing mode to the calling module. Return control. The page turning mode instructing means 11 may provide a specific page turning mode when it is not called as a default interpretation.

Next, the calling module is turned to the page turning instruction means 12.
Is called and a page turning request is made, the page turning instruction means 12 increments the call counter 17 by one and shifts the control to the page turning execution determining means 15.

The page turning execution determination unit 15 obtains the current time using the current time acquisition unit 21 and compares the obtained current time with the estimated completion time (initial value 0) set in the estimated completion time storage unit 16. I do. If the current time is earlier than the estimated completion time, the page turning execution determination unit 15 estimates that the display of the page under the screen output process has not been completed yet.
The relative page counter 18 is incremented by one and control is returned to the calling module. Conversely, if the current time is later than the estimated completion time, the page turning execution determination means 15
Since it is presumed that the display of the page during the screen output processing has already been completed, the relative page counter 18 is cleared and the control is shifted to the page turning area determining means 20.

The page turning area determination means 20 determines the page turning area to be the entire screen by referring to the page turning mode storage means 14 and in the thinning mode, and sets the value of the relative page counter 18 to the page displayed latest. The page number of the page to be displayed is obtained by adding to the number.

Further, the page turning area determining means 20 refers to the page turning mode storage means 14 and, if the mode is the degeneration mode, the page turning area according to the value of the call counter 17 indicating how continuously the page turning is requested. Of the page turning area obtained from a pointing device or the like by the page turning area origin obtaining means 23, and a rectangular area on the screen having the above-mentioned size and having this position as a middle point is determined as a page turning area. I do. Concerning the positioning of the page turning region, for example, a point pointed by the pointing device may be set as the upper left vertex of the rectangle. Then, the page turning area determination means 20 obtains the page number of the page to be displayed by incrementing the page number of the latest displayed page by one.

Further, the page turning area determining means 20 refers to the page turning mode storage means 14 and, if the mode is the thinning-out mode, the page turning operation is performed in accordance with the value of the call counter 17 indicating how continuously the page turning is requested. The size of the page turning area is determined, and when this size exceeds a certain minimum size, the reduced mode is determined. When the size becomes smaller than the minimum size, the reduced mode of the minimum size and the thinning mode are determined, and the page turning area origin is obtained. The position of a page turning area obtained from a pointing device or the like is obtained by the means 23, and a rectangular area on the screen having the above-mentioned size or the minimum size with this position as a middle point is determined as a page turning area. Then, the page turning area determining means 20 increments the page number of the latest displayed page by one or adds the relative page counter 18 to the page number of the latest displayed page.
To obtain the page number of the page to be displayed.

After the position and size of the page turning area and the page number are determined, the page turning area determining means 20 estimates the estimated completion time at which the screen output processing will be completed based on the number of screen output buffers, the number of characters to be displayed, and the like. Is calculated by the completion time calculation means 19 and is set in the estimated completion time storage means 16.

In detail, the completion time calculation means 19 calculates the required screen output time based on the information affecting the delay time such as the size of the screen display buffer and the amount of characters to be output and displayed, and the current time acquisition means 21 The estimated completion time is calculated by adding the obtained current time, and is set in the estimated completion time storage means 16.

Thereafter, the page turning area determining means 20 transfers the position and size of the page turning area and the page number and shifts the control to the screen display means 22.

The screen display means 22 extracts the contents of the corresponding page from the document based on the page number, outputs a content portion corresponding only to the page turning area on the screen, and returns the control to the calling module.

When the page turning request is made continuously in the thinning mode and the thinning mode, the calling module also calls the calling counter reset means 13 immediately after the last call of the page turning instruction means 12. To do. If this cannot be done, the calling module resets the call counter 13 when a certain period of time has elapsed in the calling module.

The call counter reset means 13 includes a call counter 17
Is reset, and the control is shifted to the page turning area determining means 20.

The page turning area determining means 20 determines that the page turning area is the entire screen since the control has been passed from the call counter resetting means 13, and sets the page number displayed latest as the page number of the page to be displayed. Next, the page turning region determining means 20 calculates the estimated completion time at which the screen output processing will be completed based on the number of screen output buffers, the number of characters to be displayed, and the like by the completion time calculating means 19 and stores the estimated completion time. The means 16 is set. Thereafter, the page turning area determining means 20 transfers the position and size of the page turning area and the page number and shifts the control to the screen display means 22.

The screen display means 22 outputs the corresponding page in the document to the entire screen based on the page number, and returns the control to the calling module. As a result, even in the reduced mode and the reduced-thinning mode, the entire contents of a certain page are displayed on the screen after the last page turning request is made.

In the description of the operation of the above embodiment, the case where the page turning is performed in the ascending order of the page numbers has been described. However, the case where the page turning is performed in the descending order of the page numbers, or the case where the page turning is performed for every predetermined number of pages, etc. Needless to say, the same operation is performed.

Also, it has been described that there are a thinning mode, a degenerate mode, and a thinning / degenerate mode as page turning modes.
It goes without saying that a conventional page turning mode in which neither thinning nor degeneration is performed may be further selectable.

By the way, in the above-described embodiment, the case where the present invention is applied to the page turning subroutine 10 of the document creation data processing device is described as an example. However, the target to which the present invention is applied is limited to the document creation data processing device and the subroutine. It goes without saying that it is not a thing.

〔The invention's effect〕

As described above, the present invention provides a page turning mode instructing means, a page turning instructing means, a call counter resetting means, a page turning mode storing means, a page turning execution determining means, an estimated completion time storing means, a calling counter, a relative page counter, A completion time calculating unit, a page turning region determining unit, a current time obtaining unit, a screen displaying unit, and a page turning region origin obtaining unit are provided, and a page turning operation can be freely performed by selecting a thinning mode, a degenerate mode and a thinning / reducing mode. By doing so, there is an effect that an interface closer to a page turning process when a person turns a normal document can be provided to the data processing apparatus.
