Description

  The present invention relates to a display scroll device that performs display data scroll processing, a display scroll device control method, a display scroll device control program, and a computer-readable recording medium that stores the program.

  In recent years, with the development of mobile devices such as smartphones, opportunities to acquire various information are increasing. Many mobile devices have small screens and cannot display all of the content at once. Therefore, when displaying content or the like, a scroll bar is displayed and the scroll is operated so that the user can browse the entire content. Note that the position of the currently displayed content on the scroll bar is realized by associating the entire range of the content with the range displayed on the screen of the entire range. By using the scroll bar, even if the content cannot be displayed all at once, the user can browse all the content.

  Further, after scrolling, scrolling in the reverse direction to find a desired part is often performed. For example, for news articles on the Internet, first scroll the entire news article, check the whole, return to the article you are interested in, read the article in detail, etc. Often return to position and display on screen.

  However, since the current scroll bar displays only the approximate position in the entire content, it is difficult to accurately and quickly return to the desired portion viewed before scrolling after scrolling.

  On the other hand, for example, Patent Document 1 describes a technique for displaying a page break such as a page break line in the content.

JP 2010-117928 A (published May 27, 2010)

  However, the conventional configuration causes the following problems. In the invention described in Patent Document 1, since page breaks and page numbers are only displayed on the screen, if the user does not scroll back in the opposite direction of scrolling, the user returns to a desired part of the content. I can't. This is no different from the operation of the conventional scroll bar.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a display scroll device that presents a scroll bar that can be accurately and quickly moved to a desired portion of content using a scroll bar. It is in realizing.

The storage unit 105 includes a scroll information storage unit 121 and a web data storage unit 122.

  The display device 1 acquires various data including content from the database 2 via the network 3 and displays the data on the display unit 103. Note that the configuration for displaying the content is possible by a known technique, and thus the description thereof is omitted.

  The storage unit 105 stores various data, and includes a scroll information storage unit 121 and a web data storage unit 122.

  The scroll information storage unit 121 stores scroll bar generation information including a display range list and a display position list created by the display data analysis unit 111 described later. Details of the display range list and the display position list will be described later.

  The web data storage unit 122 stores the web data # 1 supplied from the transmission / reception unit 101.

  The transmission / reception unit 101 receives content, a list of content, and the like that are targets for displaying the scroll bar. Further, in order to acquire such content, an instruction is transmitted to the database 2 via the network 3. In the present embodiment, the transmission / reception unit 101 receives web data # 1 indicating web content, supplies the web data # 1 to the display data analysis unit 111, and stores it in the web data storage unit 122.

  The operation accepting unit 102 accepts various operations on the display device 1 and includes a touch panel, a mouse, a keyboard, and the like. The user can give an instruction to the display device 1 via the operation reception unit 102. Examples of instructions given by the user include a scroll instruction and a display range change instruction.

  The display unit 103 displays data to be displayed and a scroll bar generated by a scroll bar generation unit 113 described later. The display unit 103 may be realized by any device as long as it can display information. Specific examples include a liquid crystal display, an organic EL (Electro Luminescence) display, and a plasma display. Can be mentioned.

  The display control unit 106 controls the display on the display unit 103. Specifically, the display data # 2 in a range that can be displayed on the display unit 103 is acquired from the web data # 1 stored in the web data storage unit 122 and displayed on the display unit 103, and the scroll bar generation unit 113 Scroll bar display information # 4 indicating the created scroll bar is acquired, and a scroll bar corresponding to the displayed content is displayed on the display unit 103.

  Further, when the display control unit 106 acquires the scroll position information # 5 from the scroll processing unit 112, the display control unit 106 acquires the display data # 2 corresponding to the position indicated by the scroll position information # 5 from the web data storage unit 122, It is displayed on the display unit 103.

  The scroll control unit 104 performs scroll processing such as scroll bar display and scroll processing, and includes a display data analysis unit 111, a scroll processing unit 112, and a scroll bar generation unit 113.

  The display data analysis unit 111 includes the web data # 1 supplied from the transmission / reception unit 101, the size information # 6 indicating the display size of the display unit 103 acquired from the display unit 103, and the display data # 2 acquired from the display control unit 106. Based on this, the size (length) of the entire range of the content indicated by the web data # 1 and the portion (length) displayed on the display unit 103 among all the content are calculated. This is performed by creating a display range list and a display position list, which will be described later. Then, the created display range list and display position list are stored in the scroll information storage unit 121 as scroll bar generation information # 3.

  The scroll processing unit 112 performs scroll processing based on the scroll instruction received by the operation receiving unit 102. Specifically, scroll position information # 5 indicating the elevator position of the scroll bar received by the operation receiving unit 102 is supplied to the display control unit 106.

  The scroll bar generation unit 113 acquires the scroll bar generation information # 3 from the scroll information storage unit 121 and generates a scroll bar. More specifically, all the pages of the web content are displayed from the size of the entire range of the content shown in the display range list, the displayed range, and the upper and lower ends of the display position shown in the display position list. A scroll bar composed of a number and an elevator representing the displayed position (page) is generated. Then, scroll bar display information # 4 indicating the generated scroll bar is supplied to the display control unit 106. Details of processing in the scroll bar generation unit 113 will be described later.

[Flow of scroll bar display processing in display device 1]
Next, the flow of scroll bar display processing in the display device 1 will be described with reference to FIG. FIG. 2 is a flowchart showing a flow of scroll bar display processing in the display device 1.

  First, the transmission / reception unit 101 receives web content (web data # 1) from the database 2 (web server) via the network 3. And it preserve | saves in the web data memory | storage part 122 (S201, display data acquisition step). Next, the display control unit 106 displays the web content stored in the web data storage unit 122 on the display unit 103 (S202).

  Next, the display data analysis unit 111 calculates the length (entire range) of the entire web content, that is, the number of pixels necessary to display the entire web content on the display unit 103 (S203).

  Next, the display data analysis unit 111 acquires the length of the content displayed on the screen (screen display range) from the display control unit 106 (S204).

  Subsequently, the display data analysis unit 111 generates a display range list from the entire range and the screen display range, and stores it in the scroll information storage unit 121. An example of the display range list is shown in FIG. The display range list 301 is a list in which the entire range and the screen display range are represented by the number of pixels. Here, the entire range is 12500 pixels, and the screen display range is 300 pixels.

  FIG. 4 shows the relationship between web content and screen display. This figure schematically shows a state in which a part of web content is displayed on the screen. The web content area other than the portion displayed on the screen can be displayed on the screen by a scroll operation. Here, the upper end of the display position represents the length from the beginning of the entire web content to the beginning of the portion displayed on the screen. Similarly, the lower end of the display position represents the length from the beginning of the entire web content to the end of the portion displayed on the screen. The screen display range is a length obtained by subtracting the upper end of the display position from the lower end of the display position, and is the length of the content displayed on the screen. The total range is the length from the beginning of the content to the end of the content.

  Next, the display data analysis unit 111 obtains the display position upper end and the display position lower end of the displayed content from the screen display range acquired from the display control unit 106 and the entire range, and generates a display position list. And stored in the scroll information storage unit 121. An example of the display position list is shown in FIG. In the display position list 501, the upper end of the display position and the lower end of the display position are represented by the number of pixels. Here, the upper end of the display position is 6800 pixels, and the lower end of the display position is 7100 pixels.

  Thereafter, the scroll bar generation unit 113 calculates the total number of pages of the web content from the display range list stored in the scroll information storage unit 121 (S207). The total number of pages represents how many times the entire range of web content corresponds to the screen display range, and is calculated by “total range / screen display range”. Round up after the decimal point.

For example, in the case of the display range list 301 in FIG.
Total range / screen display range = 12,500 / 300 = 41.66...
Therefore, the total number of pages is 42 (rounded up after the decimal point).

  Next, the scroll bar generation unit 113 executes a scroll bar generation process (S208, scroll bar generation step). Details of the scroll bar generation processing in step S208 will be described later.

  When the scroll bar is generated and saved in step S <b> 208, the display control unit 106 displays the scroll bar on the display unit 103.

  Thereafter, when a scroll operation is received via the operation reception unit 102 (YES in S210), the display control unit 106 displays the scroll destination content on the display unit 103 (S211, scroll step). Then, the process returns to step S206. Further, the display data analysis unit 111 updates the display position list. When returning from step S211 to step S206, the calculation processing of the total number of pages in step S207 may not be performed.

  On the other hand, if the screen display range change operation is accepted without accepting the scroll operation (YES in S210) (YES in S212), the process returns to step S202, and the display unit 103 has the size of the screen display range after the change. Display content.

  When the change of the screen display range is not accepted (NO in S212) and the end of content display is accepted (YES in S213), the display of the content and the scroll bar is terminated.

  When the screen display range is not changed, it is possible to prevent the user from being unintelligible by changing the total number of pages of content.

[Scroll generation processing]
Next, the flow of scroll generation processing by the scroll bar generation unit 113 will be described with reference to FIG. FIG. 6 is a flowchart showing the flow of the scroll generation process.

The scroll bar generating unit 113 first calculates the page number of the page being displayed on the display unit 103 (displayed page number). For this purpose, the scroll bar generation unit 113 acquires the display position list and the display range list from the scroll information storage unit 121, and displays the value of the display position upper end of the acquired display position list and the value of the screen display range of the display range list. To calculate the page number being displayed. Specifically, the page number being displayed is calculated by “display position upper end / screen display range”, and the decimal is rounded up. In the case of the example of the display range list 301 shown in FIG. 3 and the display position list 501 shown in FIG.
Display position upper end / screen display range = 6800/300 = 22.66 ...
Therefore, the displayed page number is 23 (rounded up after the decimal point). After calculating the displayed page number, a page list is generated from the calculated displayed page number and the total number of pages calculated in step S207 and stored in the scroll information storage unit 121. FIG. 5B shows an example of the page list 502. The page list 502 shows the total number of pages and the displayed page number. The page list 502 is a case where the total number of pages is 42 and the displayed page number is 23.

  The page number being displayed may be calculated using the value at the lower end of the display position instead of the value at the upper end of the display position. In this case, the displayed page number is calculated by “lower end of display position / screen display range”, and the decimal part is rounded down.

Also, the value at the center of the displayed screen (the center of the display position) is calculated using both the value at the upper end of the display position and the value at the lower end of the display position, and this is used to calculate the displayed page number. Also good. in this case,
Center of display position = (upper display position + lower display position) / 2
age,
Screen display range × n ≦ display position center <screen display range × (n + 1)
N is a displayed page number. Or
Screen display range × n <display position center ≦ screen display range × (n + 1)
N may be the displayed page number.

  Next, the scroll bar generation unit 113 compares the quotient of “total number of pages / 10” with the quotient of “displayed page number / 10” (S602). As a result, it is possible to determine whether or not there is a page in which the tens value of the displayed page number is larger than the current value. If the comparison results are equal, there is no page where the tens place value of the displayed page number is greater than the current value, and if the comparison results are not equal, the tens place value of the displayed page number is There will be pages larger than the value.

  If the comparison results are not equal (NO in S602), a scroll bar displaying a numerical value (numerical block) of the first digit from 0 to 9 is generated with a two-column scroll bar (S603). The tens place scroll bar generates a scroll bar displaying numerical values (numerical blocks) up to the tens place value (here, “4” on page 42) of the total number of pages calculated in step S207.

  And an elevator is produced | generated to the numerical block corresponding to the 1st value of the page number under display among the numerical values from 0 to 9 of the 1st place (S605). Further, an elevator is also generated for a numerical block corresponding to the tens place of the displayed page number.

  An example of the scroll bar generated by the flow from step S603 to step S605 is shown in FIG. The scroll bar shown in FIG. 7 includes a tenth-order scroll bar 701 and a first-order scroll bar 702. Also, a tenth-order elevator 703 and a first-order elevator 704 are displayed. Here, it is shown that the displayed page number is 23. Here, two scroll bars (701, 702) are displayed side by side, but the scroll bar of the upper digit is displayed above the scroll bar of the lower digit so that the numerical value in the scroll bar can be seen. Also good. According to this display, as will be described later, when a page number is selected from the scroll bar and the web content is scrolled to the page of the page number, for example, the state to which the page has been moved during the scrolling is displayed to the user. It becomes easy to understand. Further, only the upper digit scroll bar may be displayed, and a plurality of scroll bars may be displayed when the user confirms the number of pages or moves the page.

  On the other hand, if the compared values are equal (YES in S602), a first-order scroll bar is generated in which numerical values from 0 to the first-order value of the total number of pages are displayed (S604). The tens place scroll bar generates a scroll bar displaying numerical values up to the tens place value (here, “4” on page 42) of the total number of pages calculated in step S207.

  Then, an elevator is generated at the position of the value corresponding to the displayed page number on the scroll bar (S605).

  FIG. 8 shows an example of the crowbar generated by the flow from step S604 to step S605. FIG. 8 shows a scroll bar display example when the displayed page number is 41 pages. When the page number being displayed is 41 and the tenth-order elevator indicates 4, the numerical value of the first-order scroll bar is from 0 to 2.

  After generating the scroll bar, the generated scroll bar is stored in the storage unit 105 (S606). This completes the scroll generation process.

[Display screen example]
FIG. 9 shows an example of the scroll bar displayed on the display unit 103 in step S209 in FIG. In the example of the display screen shown in the drawing, a browser is displayed on the display unit 103, and an address display area 902, a content display area 903, a scroll bar 904, and a scroll arrow 905 are displayed. The address display area 902 is an area where the address of the displayed content, a browser forward button, a return button, and the like are displayed. The content displayed here varies depending on the content, the device being used, the browser, and the like. Content is displayed in the content display area 903.

  As shown by the scroll bar 904, the scroll bar has a two-column structure, and a number is assigned to each. Of the two-column structure, the page on the left side facing the display unit 103 corresponds to the tens place of the page number, the right side corresponds to the place of the page number, and a page in which a different color part (elevator) is currently displayed Represents. A method for generating the scroll bar 904 will be described later.

  Note that the scroll arrow 905 is not essential and may not be displayed.

[Display example of scroll bar]
In the calculation of the displayed page number in S601 of FIG. 6 described above, the calculated value is rounded up after the decimal point, but a scroll bar corresponding to the digits up to the xth decimal place (x is an arbitrary natural number) is displayed. Also good. A display example in this case is shown in FIG. In the scroll bar shown in FIG. 10A, a decimal point is added to the numerical value of the scroll bar 1002 at the first place. Thereby, it can be shown to the user that there is a display after the decimal point. In FIG. 10A, 1001 is the tens place scroll bar, 1002 is the first place scroll bar, 1003 is the first decimal place scroll bar, 1004 is the tens place elevator, and 1005 is the first place. The elevator 1006 is a first decimal place elevator.

  Further, the display indicating that the number is decimal is not limited to the display in which a decimal point is added to the numerical value of the scroll bar 1005 at the first place as described above. For example, a display in which a decimal point is added before the numerical value of the scroll bar with the first decimal place may be performed. In addition, a notation indicating that it is represented by a decimal may be displayed outside the scroll bar, for example, between the scroll bar of the first place and the scroll bar of the first decimal place.

  When the total number of pages is 3 digits or more, the scroll bar may be 3 or more. An example of three scroll bars is shown in FIG.

  This is because, for example, when the value of the total number of pages is calculated in step S207 in FIG. 2, when the scroll bar and the elevator are generated in steps S603 to S606 in FIG. This can be done by generating three tens and one place scroll bars. In FIG. 10B, 1007 is the hundreds scroll bar, 1008 is the tens scroll bar, 1009 is the first scroll bar, 1010 is the hundreds elevator, and 1011 is the tens digit. Elevators and 1012 indicate the first rank elevator.

  Moreover, when the number of digits of all the pages becomes large, the structure which displays the scroll bar of the same number as the number of digits may be sufficient.

[Example of setting the total number of pages to 100 pages]
It is also possible to set an upper limit on the number of scroll bars. For example, when the total number of pages is 100 pages or more, the number of scroll bars can be two. For this purpose, the value of the screen display range is adjusted so that the total number of pages of content in which the total number of pages exceeds 100 pages becomes 100 pages. According to this configuration, the displayed page number is the page number for all 100 pages. In other words, the scroll bar value displays the position of the screen display range in% in the entire content range, where the content upper end is 0% and the content lower end is 100%. This configuration will be described with reference to FIG. FIG. 11 is a flowchart showing the flow of scroll bar generation processing in a configuration in which the total number of pages of content is 100 pages.

  First, the scroll bar generating unit 113 determines whether or not the total number of pages is greater than 100 (S1101). If it is 100 or less (NO in S1101), the processing of S601 or less in FIG. 6 is executed.

  On the other hand, when the total number of pages exceeds 100 (YES in S1101), the scroll bar generating unit 113 updates the display range list by setting the screen display range value of the display range list to 1/100 of the total range (S1102). ). Further, the scroll bar generating unit 113 sets the total number of pages in the page list to 100 (S1103).

  Thereafter, the scroll bar generation unit 113 calculates the displayed page number. The method of calculating the displayed page number is the same as the process in step S601 described above. After calculating the displayed page number, a page list is generated with the displayed page number and the total number of pages (100 pages) (S1104).

  An example of the page list generated in step S1104 will be described with reference to FIG. FIG. 12 is a diagram illustrating a generation example of a page list. FIG. 12A is a diagram illustrating a display range list before the screen display range is changed to 1/100 of the entire range in step S1102. 12B is a diagram showing the display position list, and FIG. 12C is a diagram showing the display range list after the screen display range is changed to 1/100 of the entire range in step S1102. FIG. 12D is a diagram showing the display position list, and FIG. 12E is a diagram showing the page list generated in step S1104.

As shown in FIG. 12A, the display range list 1201 before the screen display range is changed to 1/100 of the total range in step S1102 is 40000 for the total range (number of pixels) and the screen display range (pixels). When the number) is 200, the total number of pages is 200 pages. Accordingly, it is determined that the total number of pages is greater than 100, and the screen display range of the display range list 1201 is updated to 400, which is 1/100 of the total range 40000. Therefore, the display range list shown in FIG. It becomes like 1203. And the displayed page number is
Upper end of display position / screen display range = 6800/400 = 17
Therefore, it becomes 17. Therefore, the page list created in step S1104 has a total page count of 100 and a displayed page number of 17, as shown in the page list 1205 in FIG.

  After creating the page list in step S1104, the scroll bar generating unit 113 generates a scroll bar with the tens place of 0 to 10 and the first place of 0 to 9 (S1105), and the displayed page position (displaying) Corresponding to the page number), an elevator is generated on the scroll bar (S1106).

  An example of the scroll bar generated in step S1106 is shown in FIG. As shown in FIG. 13, in the scroll bar 1311 generated in step S1106, the number from 0 to 10 is entered in the tens place scroll bar 1301, and the number from 0 to 9 is entered in the place scroll bar 1302. Is included. The scroll bar 1311 can display up to 100 pages. The tenth-order elevator 1303 and the first-order elevator 1304 are displayed at a number of positions representing the displayed page number.

  Finally, the generated scroll bar is stored in the storage unit 105 (S1107), and the scroll bar generation process in the configuration in which the total number of pages of content is 100 pages ends.

[Example of specifying the number of scroll bars]
In the example described above, the total number of pages is specified as 100. However, the number of scroll bars to be generated is k (k is a natural number) specified by the user, and the total number of pages corresponds to the number of scroll bars. May be set. In this case, the screen display range is
Screen display range = (whole range) / (k x 10)
And calculate the total number of pages as
Total number of pages = k x 10
Calculate as follows.

[Example of elevator display range]
In the example described above, the elevator is displayed in the number of displayed frames (numerical blocks) corresponding to the displayed page number, but the elevator display method is not limited to this.

For example, you may display the elevator of the size match | combined with the ratio of the display range with respect to the whole range. In particular,
The elevator may be displayed such that the display range: the entire range = the elevator display range: the length of the scroll bar.

  FIG. 14 shows a display example of an elevator having a size that matches the ratio of the display range to the entire range. In the scroll bar 1411 shown in FIG. 14, the tenth-order elevator 1403 and the first-order elevator 1404 are displayed in accordance with the lengths of the tenth-order scroll bar 1401 and the first-order scroll bar 1402.

  Further, the elevator may be displayed so as to straddle the numerical block as shown in the elevator 1404 or may be displayed so as to overlap a part of the numerical block as shown in the elevator 1403.

[Definition of the top and bottom positions of the elevator]
Next, the definition of the upper end position and the lower end position of the elevator will be described with reference to FIG. FIG. 15 shows a scroll bar 1501 and an elevator 1502. In this figure, the elevator upper end position refers to the length from the upper end of the scroll bar 1501 (upper end of the scroll bar) to the upper end of the elevator 1502 (upper end of the elevator). The elevator lower end position refers to the length from the upper end of the scroll bar 1501 to the lower end of the elevator 1502 (elevator lower end). The elevator can be generated by determining the elevator upper end position and the elevator lower end position (step S605 in FIG. 6 and step S1106 in FIG. 11).

[Elevator production method]
Next, an elevator generation method will be described with reference to FIG. FIG. 16 is a diagram for explaining a method of generating an elevator. Here, a method for generating an elevator when the total number of pages is two digits and the number of scroll bars is two will be described. In FIG. 16, m corresponds to the quotient of “display position upper end (or lower end) / (display range × 10)”. Therefore, m is high-order information such as the tens place and does not appear in the calculation formula of the scroll bar of the first place.

  First, the tens place elevator upper end position and lower end position are calculated as follows.

Elevator top position at tens place = scroll bar length x (upper display position / total range)
Elevator lower end position = Scroll bar length × (Display position lower end / total range)
In addition, the elevator upper position and the lower position of the first place are calculated as follows.

The remaining display position upper / (display range × 10) and X U1, and extra to X D1 of the display position bottom / (display range × 10). And
Elevator top position at the first place = Scroll bar length x (X U1 / (Display range x 10))
Elevator lower end position of first place = scroll bar length × (X D1 / (display range × 10))
Calculate with X U1 is, (10 × m + 1) represents the length of the page head of the, X D1 represents a length obtained by adding the display range in length from the head of (10 × m + 1) th page. Thereby, the display position of an elevator can be determined and an elevator can be produced | generated.

When the quotient value of “display position upper end / display range × 10” and the quotient value of “display position lower end / display range × 10” are different, that is, between X U1 and X D1 (10 When the boundary between the (× m) page and the (10 × m + 1) page is sandwiched, the top of the first elevator is positioned below the bottom of the first scroll bar. In this case, the elevator may be displayed below the elevator upper end position and to the lower end of the scroll bar, or may be displayed above the elevator lower end position and to the upper end of the scroll bar.

In addition, when the total number of pages of content is 100 pages or more and the number of scroll bars is 3 or more, an elevator displayed on the scroll bar of the highest M-th digit (M is an integer of 3 or more)
Elevator top position of the highest digit = scroll bar length x (upper display position / total range)
Elevator lower end position of the highest digit = scroll bar length x (display position lower end / full range)
For other elevators in the Nth digit (N = 1 to M−1), the remainder obtained by dividing the upper end of the display position by the display range × 10 N is X UN, and the lower end of the display position is the display range × 10 N The remainder after dividing by X DN
Elevator top position of the Nth digit = scroll bar length × (X UN / (screen display range × 10 N ))
Nth digit elevator bottom position = scroll bar length × (X DN / (screen display range × 10 N ))
A scroll bar can be generated by calculating with

  In addition, these calculations are not applied to the display of the scroll bar for all the digits, but are applied to some scroll bars such as only the first-order scroll bar. You may display on the whole numerical block showing a number.

[Example of setting the minimum value for the elevator width]
In the above-described method for calculating the elevator upper end position and lower end position, the elevator width (elevator width) may be less than one pixel. In this case, the elevator is not displayed. Moreover, even if it is 1 pixel or more, if the width | variety is small, visibility will worsen. Therefore, a configuration that determines the minimum value of the elevator width may be employed. As a result, the elevator is displayed with the number of pixels equal to or greater than the minimum value. In addition, the elevator width | variety here is the value (length) which pulled the elevator upper end position from the elevator lower end position.

  As a method of making the elevator width equal to or larger than a certain minimum value (number of pixels), (1) a method of recalculating the elevator lower end position based on the elevator upper end position, and (2) a calculation of the elevator upper end position based on the elevator lower end position. There is a method of re-calculating, and (3) a method of obtaining a reference value and recalculating both the elevator lower end position and the upper end position.

  For example, consider a case where the minimum value of the elevator width is 15 pixels, the elevator upper end position and lower end position of each scroll bar are calculated, and the elevator width is recalculated from the result.

Elevator width = elevator lower end position−elevator upper end position As a result of the above calculation, when the elevator width is 15 or more, the elevator lower end position and the elevator upper end position remain unchanged, and the elevator is generated and displayed.

On the other hand, if the elevator width is less than 15 as a result of the above calculation,
Elevator lower end position = Elevator upper end position + 14
After recalculating, the elevator is generated and displayed ((1) above). Or
Elevator top position = elevator bottom position -14
After recalculating, the elevator is generated and displayed ((2) above).

Alternatively, a value obtained by subtracting 7 from the calculated intermediate value between the elevator upper end position and the elevator lower end position (average value, which is the reference value of (3) above) is the new elevator upper end position, and 7 is added. It is set as a new elevator lower end position (above (3)). That is,
Intermediate value = (elevator lower end position + elevator upper end position) / 2
Elevator top position = Intermediate value -7
Elevator top position = intermediate value +7
And

  When the elevator width is constant, the elevator upper end position may be a negative value, or the elevator lower end position may be a value greater than the scroll bar length. In this case, the elevator display does not fit in the scroll bar as it is. Therefore, when the elevator display does not fit within the scroll bar, the elevator upper end position and lower end position are recalculated so that the elevator fits within the scroll bar.

  For example, if the minimum value of the elevator width is 15 pixels and the elevator width is less than 15 when recalculated by any of the above methods, the value of the elevator upper end position or the elevator lower end position is changed.

In particular,
Elevator lower end position = Elevator upper end position + 14
As a result of calculating the elevator lower end position by means of the elevator lower end position is larger than the scroll bar length,
Elevator top position = scroll bar length -14
Elevator lower end position = scroll bar length.

Also,
Elevator top position = elevator bottom position -14
As a result of calculating the elevator top position by means of the elevator top position becomes a negative value,
Elevator top position = 0
Elevator bottom position = 14
And

Or
Intermediate value = (elevator lower end position + elevator upper end position) / 2
Elevator top position = Intermediate value -7
Elevator top position = intermediate value +7
As a result of calculating the elevator upper end position and the elevator lower end position by means of the elevator lower end position is larger than the scroll bar length,
Elevator top position = scroll bar length -14
Elevator lower end position = scroll bar length. Also, if the same calculation results in a negative elevator top position,
Elevator top position = 0
Elevator bottom position = 14
And

  In addition, when the elevator lower end position becomes a value larger than the scroll bar length, only the calculation of making the elevator lower end position equal to the scroll bar length may be performed. Further, when the elevator upper end position becomes a negative value, only the calculation of setting the elevator upper end position to 0 may be performed. In such a calculation method, when the elevator is at the upper end position or the lower end position of the scroll bar, the width of the elevator is narrower than when the elevator is at another position. However, when the minimum value is not set for the elevator width, the width of the elevator may be extremely narrow, such as 1 pixel. However, when the minimum value is set for the elevator width, There is nothing. Therefore, operability can be improved and user convenience can be enhanced.

[Example where the first-order scroll bar corresponds to n pages]
In FIG. 6 described above, the flow indicating the numerical blocks (0 to 9) for 10 pages is shown in the first-order scroll bar, but the first-order scroll bar is not limited to this. For example, an arbitrary page number up to n pages (n is a natural number) may be displayed on the first scroll bar. A flow of scroll bar generation processing when displaying page numbers up to n pages in the first place will be described with reference to FIG.

  As shown in FIG. 17, the scroll bar generating unit 113 first calculates the page number of the page being displayed on the display unit 103 (displayed page number), and generates a page list (S1701). Next, the scroll bar generation unit 113 compares the quotient of “total number of pages / n” with the quotient of “displayed page number / n” (S1702).

  If the comparison results are not equal (NO in S1702), a two-column scroll bar displays a numerical value of 0 to n in the first place, and 0 to "total pages / n" in the tenth place. A scroll bar displaying a numerical value is generated (S1703). Here, when “the quotient of the total number of pages / n” is larger than 9, the numbers above 9 put in the numerical block of the scroll bar are displayed in alphabets (for example, 0, 1,..., 9, A, B, etc.).

  And an elevator is produced | generated to the numerical value block corresponding to the value of the 1st place of the page number under display among the numerical values of 0 to n of the 1st place (S1705). Further, an elevator is also generated for a numerical block corresponding to the tens place of the displayed page number.

  On the other hand, if the compared values are equal (YES in S1702), the first digit is displayed as a value from 0 to “the remainder of all pages / n”, and the tenth digit is represented as a value from 0 to “the total number of pages / n”. A scroll bar displaying is displayed (S1704).

  Then, an elevator is generated to a value corresponding to the displayed page number (S1705), and a scroll bar is generated.

  After generating the scroll bar, the generated scroll bar is stored in the storage unit 105 (S1706). This completes the scroll generation process.

  Note that displaying the page number of page n in the first place is equivalent to being displayed in n-ary numbers, except that numbers of 10 or more are displayed in alphabet.

[10th place scroll bar length: example of 1st place scroll bar length = n: 1]
In FIG. 11, when the total number of pages is 100 pages or more, an example in which the tens place scroll bar and the first place scroll bar have a ratio of 10: 1 has been described. A ratio of n: 1 may be displayed. The flow of scroll bar generation processing when the tenth-order scroll bar and the first-order scroll bar have a ratio of n: 1 will be described with reference to FIG. FIG. 18 is a flowchart showing the flow of scroll bar generation processing when the tenth-order scroll bar and the first-order scroll bar have a ratio of n: 1.

As shown in FIG. 18, the scroll bar generation unit 113 first determines whether or not the total number of pages is greater than n 2 (S1801). Then, if the total number of pages is n 2 or less (NO in S1801), a numerical block for n pages, that is, 0 to n−, is displayed on the first scroll bar in the same process as the process after step S1701 in FIG. Proceed to the process of displaying n number blocks each containing 1 number.

On the other hand, the total number of pages is greater than n 2, and the value of the screen display range 1 / n 2 of the total range (S1802), the value of the total number of pages of the page list to n 2 (S1803). Thereafter, the page number being displayed is calculated, and a page list is generated (S1804).

  Then, the first-order scroll bar is generated as a scroll bar in which a numerical block of 0 to n-1 and the tenth-order scroll bar is displayed from 0 to “quotient of the total number of pages / n” (S1805). The elevator at the second place is displayed in the numerical block of “quotient of displayed page number / n”, and the elevator at the first place is displayed in the numerical block of “the remainder of displayed page number / n” (S1806).

In step S1801, although the total number of pages is determined whether greater or not than n 2, this determination is not necessary. Instead of performing this determination process, the process may proceed directly from step S207 to step S1802. In this case, even if the total number of pages is n 2 or less, the total number of pages in the page list is changed to n 2 pages in step S1802.

  In the above example showing the range for n pages (0 to n-1 numerical blocks) on the first-order scroll bar, the elevator is displayed on the entire numerical block corresponding to the displayed page number. As shown, an elevator having a size matching the screen display range (the ratio of the size to the entire range) may be displayed.

In this case, the calculation performed in the elevator generation step of step S605 or step S1106 is as follows. The elevator of the scroll bar representing the widest range corresponding to the scroll bar with the highest digit is
Elevator top position = scroll bar length x (upper display position / total range)
Elevator lower end position = scroll bar length x (display position lower end / full range)
Calculate and display with. In the other digits, the elevator upper end position and lower end position of the elevator of the Nth scroll bar (abbreviated as Nth elevator) from the narrower scroll range are calculated as follows. The remainder obtained by dividing the upper end of the display position by the display range × n N is defined as X UN, and the remainder obtained by dividing the lower end of the display position by the screen display range × n N is defined as X DN .
Nth elevator top position = scroll bar length × (X UN / (screen display range × n N ))
Nth elevator bottom position = scroll bar length × (X DN / (screen display range × n N ))
[Example of not displaying the numerical block on the scroll bar]
In the example of the scroll bar shown so far, the elevator is displayed in the numerical block on the scroll bar corresponding to the displayed page number. However, in the present invention, the numerical block is not necessarily displayed. For example, as will be described later, the display page number (numerical block) may not be displayed, and a scroll bar including a plurality of scroll bars in which the amount of movement of the elevator with respect to the scroll amount of the web content being displayed may be different.

[How to scroll using an elevator]
Next, the flow of scrolling the content page using the elevator will be described with reference to FIG.

  First, the operation accepting unit 102 accepts an operation of the tens place scroll bar displayed so as to overlap the first place scroll bar (S1901). Next, the scroll processing unit 112 determines whether or not the operation performed by the user on the scroll bar is to select a numerical value (S1902).

  If the operation content received by the operation receiving unit 102 is not to select a numerical value, that is, an operation of dragging or flicking the tenth-order elevator (NO in S1902), an instruction from the scroll processing unit 112 Thus, the display control unit 106 causes the display unit 103 to display the display range of the content corresponding to the tenth-order elevator position dragged or flicked (S1903).

  When the operation receiving unit 102 receives the end of the drag or flick operation (S1904), the display control unit 106 displays the content of the elevator range after the drag or flick on the display unit 103 (S1904).

  On the other hand, if the operation received by the operation receiving unit 102 in step S1902 is an operation of selecting a numerical block on the tens place scroll bar (YES in S1902), the display control unit 106 displays the display unit 103 on the display unit 103. The content at the position corresponding to the received numerical block is displayed (S1906). Furthermore, the scroll bar generating unit 113 displays a scroll bar in which the first-order scroll bar is displayed on the tenth-order scroll bar on the display unit 103 (S1907).

  FIG. 20 shows an example in which after the numeric value of the tens place scroll bar is selected, the first place scroll bar is displayed on the tens place scroll bar. First, the display unit 103 displays the first page of the numerical block selected by the operation received by the operation receiving unit 102 in step S1906. Then, as shown in the display example 2001 of FIG. 20, when an operation for selecting the three numerical blocks displayed in the tens place scroll bar 2003 is accepted, as shown in the display example 2002, the first place scroll bar. 2004 is displayed in front of the tens place scroll bar 2003.

  Then, the tenth-order elevator 2005 moves to the position indicating the numerical block 3, and the first-place elevator 2006 moves to the numerical block 0. The numerical block 3 indicated by the tenth-order elevator 2005 indicates that there are 30 page numbers. When the numerical block of the tens place scroll bar 2003 is selected, only the position of the tens place elevator 2005 is moved to the selected position without moving the first place elevator 2006. You may display the page of the page number.

  In step S1907, after the first-order scroll bar is displayed on the tenth-order scroll bar, the operation receiving unit 102 receives the operation of the first-order scroll bar (S1908). Then, it is determined whether or not the received operation content is for selecting a numerical value (S1909). When the received operation content is an operation for selecting a numerical value (YES in S1901), the display control unit 106 displays the content of the selected page. Is displayed on the display unit 103 (S1910).

  Then, the scroll bar generation unit 113 generates a scroll bar in which the tenth-order scroll bar is displayed on the first-order scroll bar, and displays the scroll bar on the display unit 103 (S1911). As described above, the tenth and first place numerical blocks are selected from the scroll bar, and the page number of the content to be displayed is designated.

  On the other hand, if the operation performed in step S1909 is not an operation of selecting a numerical value, that is, if the first-order elevator is dragged or flicked (NO in S1909), the display control unit 106 performs dragging or flicking. The content corresponding to the elevator position inside is displayed on the display unit 103 (S1912).

  Next, the scroll bar generating unit 113 determines whether or not the elevator that is being dragged or flicked has moved to the end of the scroll bar (upper or lower end of the scroll bar) (S1913). When it has moved to the end (YES in S1913), the scroll bar generation unit 113 displays the first-order elevator from the end opposite to the currently displayed position (S1914). Also, if the number of the tenth place elevator is advanced in the direction that the numerical value of the first place elevator is increasing, the numerical value is incremented by 1, and if the number of the first place elevator is proceeding in the direction that the numerical value of the elevator is decreased, the numerical value is 1 It is displayed at the reduced position.

  FIG. 21 shows an example in which the elevator has moved to the end of the scroll bar. As shown in FIG. 21, from the state shown in the display example 2101, that is, the tenth-order elevator 2106 shows 3 and the first-order elevator 2107 shows 3, the first-order elevator 2107 is raised. Drag or flick in the direction (the direction in which the number decreases).

  When the first place elevator 2107 reaches the upper end of the scroll bar (display example 2102) and further dragging or flicking continues further, the first place elevator 2107 is moved to the first place scroll bar 2105. And display from the end opposite to the current position (display example 2103).

  At this time, the tenth place elevator 2106 is displayed in conjunction with the first place elevator 2107. That is, in the display example 2101, it is displayed above the center of the numerical block 3 (in the direction in which the number decreases). Then, the elevator 2106 moves upward along with the drag of the first place elevator 2107, and when the first place elevator 2107 reaches the end of the first place scroll bar 2105, the elevator 2106 also moves to the upper end of the numerical block 3. Is displayed (display example 2102).

  After that, when the elevator 2107 is displayed at the opposite end of the first-order scroll bar 2105, the elevator 2106 is displayed at the lower end (numerical block 3 side) of the numerical block 2 (display example 2103).

  After the process of step S1914 or before the elevator goes to the end of the scroll bar (NO in S1913), the drag or flick ends (S1915), and when a predetermined time elapses (YES in S1916), the scroll bar generating unit 113 Then, the display unit 103 is displayed so that the tens place scroll bar is above the first place scroll bar (S1917). On the other hand, if the operation accepting unit 102 accepts an operation on the first scroll bar before the predetermined time has elapsed (NO in S1916), the process proceeds to step S1909. The above is the flow of scrolling the content page using the elevator.

[Modification of scroll bar]
In the above-described embodiment, the configuration using the scroll bar displaying the numerical block has been described. However, the scroll bar is not limited to this. For example, a scroll bar that does not display numerical blocks may be used.

  FIG. 22 shows a scroll bar that does not display numerical blocks. In the example shown in FIG. 22, a scroll bar 2204 in which no numerical block is displayed is shown. The scroll bar 2204 is displayed on the display unit 103 together with a display area 2202 displaying a browser function such as address display and an area 2203 displaying web content. As described above, the scroll arrow 2205 is used for scrolling the web content displayed in the area 2203. When the user operates the scroll arrow 2205 by clicking or the like, the web content scrolls in the direction of the arrow displayed on the scroll arrow 2205. At this time, the elevator displayed on the scroll bar 2204 also moves together with the scrolling of the content.

  In the above-described embodiment, the display of the web content is taken as an example, and the display of the scroll bar and the use of the scroll bar have been described. However, the scroll bar of the present invention can be used not only for displaying web contents but also for other displays that require scrolling, such as document files, presentation files, and file list displays. In the following, an example of use other than the display of web content will be described.

[Example of application to document creation software]
FIG. 23 shows an example in which the scroll bar according to the present invention is displayed on the document creation software. A display screen example 2301 shown in FIG. 23 shows a display area 2302 for document creation software functions such as creating and saving a new document, a document display area 2303, a scroll bar 2304, and a scroll arrow 2305.

  In the case of document creation software or the like, the page number is set in advance by the document creation software itself. Therefore, it is not necessary to calculate the total number of pages and the displayed page number from the entire range and the screen display range, and the scroll bar can be displayed and generated by using the page number set by the document creation software. it can. In the example of the flowchart of the scroll bar display process of FIG. 2 described above, it can be performed from step S208.

  Note that the page number being displayed may be a page number specified by the document creation software.

  Also, depending on the settings of the document creation software, there may be a case where a plurality of pages are displayed continuously in the scroll direction (vertical direction) within the same screen (FIG. 23). In this case, in the displayed text, the page number of the page displayed at the upper end of the document display area 2303 of the display screen example 2301 may be the displayed page number. Alternatively, the page number of the page displayed at the lower end of the document display area 2303 may be the displayed page number. Furthermore, the page number of the page displayed in the center of the document display area 2303 may be set as the displayed page number. That is, any page number may be used as the displayed page number as long as it is the page number of the page displayed in the text display area 2303.

  In the case of document creation software or the like, two pages may be displayed side by side as shown in FIG. When displaying two pages side by side, an elevator indicating the range of the displayed page may be displayed in the range of the corresponding two pages on the scroll bar. FIG. 24 shows an example of an elevator displayed in the range of two pages.

  A display screen example 2401 shown in FIG. 24 shows a display area 2402 of document creation software functions such as new creation / saving of a document, a document display area 2403, a scroll bar 2404, and a scroll arrow 2405. In the display screen example 2401 shown in FIG. 24, pages 23 and 24 are displayed by an elevator. Note that the method for determining (or determining) the page number of the page being displayed (the page number being displayed) is the same as in the case of the scroll bar displaying the elevator within the range of one page described above.

  Also, even when two pages are displayed side by side with document creation software or the like, the range of the elevator displayed on the scroll bar may be the range of one page. The displayed page number indicated by the elevator may be determined as the left side or the right side of the two aligned pages.

  When displaying an elevator in the range of two pages, there are cases where the pages to be displayed by the elevator are two pages, that is, a page with a first place value of 9 and a page with 0. In this case, the following two types of elevator display can be considered.

  In the first plan, the elevator display shows only one of the pages. For example, if the displayed pages are 2 pages of 29 pages and 30 pages, elevators are displayed at the tens place 2 (or 3) position and the tens place 9 (or 0) position. Or 30) display a page.

  The second proposal shows elevators in both the numeric blocks 9 and 0 of the first-order scroll bar to show both pages, and the two numeric blocks 2 and 3 for the tenth-order scroll bar. The elevator is displayed.

  Further, as described above, the numerical block indicating the total number of pages may not be displayed on the scroll bar. In this case, the elevator position may be calculated from the entire range and the screen display range, not from the information of the total number of pages and the displayed page number given from the document creation software. A display example in this case is shown in FIG.

  A display screen example 2501 shown in FIG. 25 shows a display area 2502, a document display area 2503, a scroll bar 2504, and a scroll arrow 2505 for document creation software functions such as new creation and storage of a document. FIG. 25 shows a case where two pages are displayed side by side, but when displaying one page at a time, a scroll bar that does not display a numerical block may be used.

[Example of application to electronic books]
In the above-described embodiment, the case of scrolling in the vertical direction has been described, but it is also possible to use it in the case of scrolling in the horizontal direction. As an example used when scrolling in the horizontal direction, a case where the scroll bar according to the present invention is displayed on the display screen of an electronic book will be described.

  FIG. 26 shows a case where the scroll bar according to the present invention is displayed on the display screen of the electronic book.

  In the display screen example 2601 shown in FIG. 26, a display area 2602 for the functions of an electronic book such as a bookmark / marker, a display area 2603 for the contents of the electronic book, a tenth-order scroll bar 2604, a first-order scroll bar 2605, a scroll Arrow 2606 is shown.

  A display screen example 2601 in FIG. 26 shows the entire screen of the device being used or a part of the screen such as a window. The display 2602 of functions such as bookmarks and markers differs depending on the electronic book display device used.

  In the electronic book, the content itself has page information as in the document creation software described above. Therefore, it is not necessary to calculate the total number of pages and the displayed page number, and the display of the scroll bar can be displayed by taking out the total number of pages and the displayed page number from the page information held by the electronic book. It can be carried out.

  In an electronic book, scrolling is performed in the horizontal direction of the screen. Scrolling here refers to the effect of turning the page by flicking or dragging horizontally on the part of the screen where the electronic book document is displayed. This includes displaying the previous or next page.

  When scrolling horizontally, the direction in which the number of pages increases depends on the content. Therefore, the display of the scroll bar may be a display that matches the direction in which the number of pages increases.

  For example, FIG. 26 shows a case of displaying horizontally written electronic book content. In general, horizontally-written electronic book contents scroll to the next page when scrolled to the right and to the previous page when scrolled to the left. That is, when scrolling leftward, the number of pages increases, and when scrolling rightward, the number of pages decreases. The scroll bar is also displayed with a large numerical block on the right and a small numerical block on the left.

  On the other hand, FIG. 27 shows a case of displaying vertically written electronic book content. In the display screen example 2701 shown in FIG. 27, a display area 2702 for electronic book functions such as bookmarks and markers, a display area 2703 for electronic book contents, a tens place scroll bar 2704, a first place scroll bar 2705, and a scroll. Arrow 2706 is shown.

  As shown in a display screen example 2701, in the case of vertically written electronic book content, the number of pages increases when scrolling leftward and the number of pages decreases when scrolling rightward, contrary to the case of horizontal writing. Is common. For this reason, the scroll bar is also displayed in accordance with this, that is, a scroll bar displaying a large numerical value in the left direction and a small numerical value in the right direction.

  In the display of an electronic book, as shown in FIG. 28, two pages of spread may be displayed on the display screen. FIG. 28 shows an example of a display screen when two pages of spread are displayed on the display screen.

  In the display screen example 2801 shown in FIG. 28, an electronic book function display area 2802 such as a bookmark / marker, an electronic book content display area 2803, a tens place scroll bar 2804, a first place scroll bar 2805, and a scroll. Arrow 2806 is shown.

  In this case, the elevator may be displayed for two pages in the same manner as described in the case of the two-page display in the scroll bar in the document creation software described above. Similarly to FIGS. 26 and 27, the arrangement of numerical blocks displayed on the scroll bar may be changed depending on the scrolling direction. FIG. 28 shows an example of vertically written electronic book content, which is an example in which the number of pages increases when scrolling leftward.
