Description

  The present invention relates to a document management program for managing documents, and more particularly to a technique for supporting a user to grasp the contents of a document by displaying thumbnails.

A document management program such as a viewer has a function of displaying an image obtained by reducing an original image called a thumbnail conventionally (see, for example, Patent Documents 1 and 2).
By displaying thumbnails, it is possible to understand the outline of the original image without opening the image with a dedicated application.
JP 5-153370 A Special Table 2005-223854

By the way, the inventor of the present application is considering the development of a document management program for displaying thumbnails of pages for a document composed of a plurality of pages.
When displaying thumbnails, it may be possible to simply display all thumbnails of the pages constituting the document. However, for example, it is considered difficult to recall the contents of the original page image from the thumbnail for pages such as the center of characters, and it may take time to understand the contents of the document, especially when the number of pages becomes enormous. is there.

  The present invention has been made in view of the above-described problems. In a document management program for displaying thumbnails of pages constituting a document, the present invention is directed to shortening the understanding of document contents by narrowing down the number of thumbnails to be displayed. An object of the present invention is to provide a document management program.

  In order to solve the above-described problem, a document management program according to the present invention is a document management program for managing a document composed of N (≧ 2) pages, and includes a determination step for determining the importance of each page. The computer is caused to execute a display control step for controlling whether or not to display thumbnails obtained by reducing the page image in accordance with the determined importance.

  The thumbnail display method according to the present invention is a thumbnail display method for displaying a thumbnail of a document composed of N (≧ 2) pages, and the importance level of each page is determined based on a predetermined determination criterion regarding the page. A determination step for determining, and a display control step for controlling whether or not to display a thumbnail obtained by reducing the page image according to the determined importance.

  According to the configuration described in the means for solving the problem, for example, the thumbnail of a page determined to be unimportant is controlled in order to control whether or not to display a thumbnail obtained by reducing the page image according to the determined importance. By omitting the display and narrowing down to the thumbnail display of pages that are determined to be important, it is possible to check the large number of thumbnails while preventing the user from having to check the huge number of thumbnails, and by narrowing down to the important thumbnail display, the overview of the entire document Can be understood.

Further, the display device further includes condition display means for displaying a condition relating to an item characterizing the page so that the condition can be set. In the determination step, the importance is determined based on the set condition.
According to this configuration, it is possible to determine the importance according to the user's intention.
In addition, the condition relating to the item characterizing the page includes a condition relating to the reference level of the page, and in the determination step, the higher the reference level of the page, the higher the importance is determined.

A page with a high reference level is considered to be a page attracting attention in the document, and according to this configuration, it is possible to make the determination more effectively by using it for determining the importance.
The reference level of the page is related to at least one of a page display count, an edit count, a print count, and a reference count from a search result.

The condition relating to the item characterizing the page includes a condition relating to ease of recognizing the original page image from the thumbnail.
In addition, the condition relating to the ease of recognizing the original page image from the thumbnail relates to the degree to which at least one of a figure, a photograph, an illustration, a graph, and a table in the page is included.

According to this configuration, for example, even if a page including a graph is thumbnailed, it is relatively easy to imagine the original page image. For example, it is possible to perform efficient thumbnail display by determining the importance of a page that is compatible with such thumbnailing to be high.
The condition relating to the ease of recognizing the original page image from the thumbnail is related to the size of characters in the page or the presence or absence of decoration.

For example, in a page image that is small and has no decoration and is centered on characters, readability may be impaired by thumbnailing (only the page layout can be confirmed), and it is difficult to imagine the original page image from the thumbnail. According to this configuration, it is possible to effectively perform the determination by using the character size and the presence / absence of the character decoration in the determination of the importance.
The condition relating to the item characterizing the page includes a condition relating to whether or not the designated character string is included.

  In addition, the method further includes a reception step for accepting registration of the document and a creation step for creating a corresponding thumbnail for each page included in the registered document. In the determination step, whether each page is important or not important. The display control step receives a thumbnail display sub-step for displaying a thumbnail for one page and an item indicating movement to the next page and a selection of the displayed item. A thumbnail sub-step corresponding to a page determined to be unimportant after the next page is skipped, and a moving sub-step for switching to display of a thumbnail corresponding to the first determined page after the next page is included. .

  Another document management program according to the present invention is a reception step for accepting registration of a document including N (≧ 2) pages, and whether each page included in the registered document is important or not important. And a creation step for creating a thumbnail with a reduced page image for each page determined to be important.

  According to this configuration, for example, it is possible to reduce the processing load and management resources associated with thumbnail creation by determining the importance of the page first and not creating thumbnails of page images with low importance. Become.

Hereinafter, the document management program according to the present embodiment will be described using a PC (document management system) in which the program is installed.
<Configuration>
FIG. 1 is a diagram showing an external appearance of a PC.
A PC 1 as a document management system includes a PC main body 2, a keyboard 4, a mouse 5, and a monitor 6.

The PC main body 2 houses an HDD (Hard Disk Drive) 8 in the casing. In the HDD, documents 9a to 9c, a document management program 10, and an important page table 12 are stored.
The documents 9a to 9c are data for a plurality of pages created by, for example, document creation software, presentation software, spreadsheet software, image editing software, or the like.

The keyboard 4 and the mouse 5 are known input devices and accept operations from the user (Mr. A).
FIG. 2 is a functional block diagram relating to the operation of the document management program.
The thumbnail creating unit 20 is provided with the pages included in the document one page at a time from the document storage area 22. Then, a thumbnail is created from the image of the provided page, and the created thumbnail is stored in the thumbnail storage area 24.

The database 26 has a data structure that matches the image of the page in the document storage area 22 with the thumbnail in the thumbnail storage area 24. It also manages parameters that characterize the pages contained in the document. This characterizing parameter is updated as needed as the document is edited.
As the data structure, as illustrated in FIG. 3, the table 27 related to the document name “example.xml” includes “page number”, “thumbnail storage path”, “display count”, “font size”, and “photo”. Contains items.

The items “page number” and “thumbnail storage path” associate the page number in the document with the location of the thumbnail of each page.
The items “display count”, “font size”, and “photo” are parameters that characterize each page.
Returning to FIG. 2, the important page determination unit 28 refers to a parameter characterizing the page from the database 26 under the determination method set by the user, and determines whether it is important or not.
<Operation>
4 to 7 are flowcharts showing the processing contents executed by the document management program. The processing contents are executed by the functional block described with reference to FIG.

In document registration (S11), document registration is first accepted (S21: Yes).
FIG. 8 is a diagram illustrating an example of a document to be registered. The document name “example.xml” is a 6-page report. In the following, this report may be used as an example to clarify the operation.
The features of each page are as follows. One page contains a large font, two pages contain a picture of a cat, four pages contain a graph, and the bottom right of page 6 includes a figure [FIG. 8 (b). ].

When registration is accepted, thumbnails of all pages are created (S22). When the document of FIG. 8 is registered, six thumbnails corresponding to each of the six pages are created.
Next, in the important page table creation (S12), a dialog is displayed (S31), item settings are accepted (S32), and an important page table is created based on the accepted settings (S33).
FIG. 9 is a diagram showing a dialog displayed in step S31.

The dialog 40 receives a setting of conditions for determining an important page, and receives ten types of conditions 41 to 50 that characterize the page. In each of the conditions 41 to 50, check boxes 41a to 50a for switching the validity of the conditions and spin boxes 41b to 45b and 41c to 45c for specifying variables are displayed.
Conditions 41 to 45 are conditions relating to the number of times the page is referred to in the order of display count, edit count, click count, number of times adopted from the search result, and print count.

As described above, a page having a larger number of times of reference is considered to be an important page for the user.
The condition 46 is a condition as to whether or not a specific character string is included. The condition 47 is a condition as to whether or not a specific range of numbers is included.
The condition 48 is a condition related to character decoration such as color characters, underline, bold (bold), italic, strikethrough.

The condition 49 is a condition related to the font size.
Note that standardized tags are generally used for XML documents, so it is possible to determine the type and font size of character decorations in a document by analyzing the tags. It is.
The condition 50 is a condition regarding the presence / absence of a photograph, a diagram, a table, a graph, and an illustration.

As in conditions 49 and 50, pages with large font sizes and pages containing photos, diagrams, tables, graphs, and illustrations are considered to be easy to understand even if they are thumbnailed, and are suitable for thumbnails. .
FIG. 10 is a diagram illustrating an example of the important page table.
The table 12a includes “page number” and “important flag” as table items.

The “important flag” is determined based on the condition set in the dialog 40 for the important page determination method, and an important flag is set if any of the conditions 41 to 50 is satisfied.
Returning to FIG. 4, in the thumbnail display (S13), if there is a thumbnail display request (S41: Yes), thumbnails of important pages are displayed (S42).

FIG. 11 shows an example of thumbnails to be displayed.
As shown in FIG. 11A, in the window 51, a thumbnail for the second page, arrows A to D as items for selecting the moving direction, and a check box 52 for checking whether or not the thumbnail is importantly set are displayed. Has been.
When the selection of the arrow D is accepted, the next three pages which are non-important pages are skipped, and the display is moved to the first important page 4 (S43: arrows D, S47 and S48). In order to make it easier to intuitively understand that page 3 has been skipped (page feed), switching the thumbnail display from page 2 to page 3 to page 4 has an animation effect that slides the page. (FIG. 11: window 54).

When the selection of the arrow A is accepted in the window 56, it moves to the second page which is the first important page before the previous page (S43: arrows A, S44).
When the selection of the arrows B and C is accepted, it moves to the previous page or the next page, respectively (S43: arrows B, S45, S43: arrows C, S46).
If the previous page does not exist on the first page, the arrows A and B are not displayed, and if it is the last page, the arrows C and D are not displayed.

As described above, according to this operation example, thumbnails of unimportant pages (FIG. 11: page 3) are skipped and only thumbnails of important pages (FIG. 11: page 2, page 4) are displayed. Users can understand important documents in a shorter time by referring to important pages.
(Other)
(1) In the above-described embodiment, it has been described that thumbnails for all pages in a document are created. However, important pages may be determined first and thumbnails for only important pages may be created.

By reducing the number of thumbnails to be created, CPU processing load, HDD area occupation, thumbnail management burden, etc. can be avoided. Hereinafter, such a configuration example will be described as a modification.
FIG. 12 is a functional block diagram relating to the operation of the document management program in the present modification. The same functional blocks as those in FIG.

The important page determination unit 29 issues a creation instruction to the thumbnail creation unit 20.
FIG. 13 is a flowchart showing the processing content related to document registration in this modification.
When a document is registered (S51), a dialog is displayed (S52), and item settings are accepted (S53). Based on the accepted setting, an important page table is created (S54), and thumbnails are created only for pages determined to be important (S55).

For example, when the important page table of FIG. 10 is created, thumbnails of only 1, 2, and 4 pages are created.
(2) In the above-described embodiment, the important flag is determined based on the binary value indicating whether the condition matches the condition of the dialog 40 (FIG. 6). For example, the score is determined based on the degree of matching with the set condition. By calculating and handling the top ranking page of the score as an important page, more precise conditioning may be supported.

(3) In the embodiment, the example in which thumbnails of one document are displayed as shown in FIG. 11 has been described. However, as shown in FIG. 14, thumbnails of a plurality of documents are displayed in a window. It doesn't matter.
As shown in FIG. 14, thumbnails 61 to 66 of important pages included in each of the six documents are displayed in the window 60.

(4) The document management program according to the present embodiment can be applied as a thumbnail display method capable of grasping the contents of a document at a glance.
Examples of the program include magnetic recording media such as magnetic tape and flexible disk, optical recording media such as DVD, CD-ROM, CD-R, MO, and PD, and flash memory recording media such as Smart Media (registered trademark). It can be recorded on various computer-readable recording media, and may be produced, transferred, etc. in the form of the recording medium, wired and wireless various networks including the Internet in the form of programs, In some cases, the data is transmitted and supplied via broadcasting, telecommunication lines, satellite communications, or the like.

  Further, the program need not include all modules for causing the computer to execute the processing described above. For example, a communication program, a program included in an operating system (OS), or the like may be separately installed on a PC. It is also possible to cause the PC to execute each process of the present invention using various general-purpose programs that can be used. Therefore, it is not always necessary to record all the modules on the recording medium of the present invention, and it is not always necessary to transmit all the modules. Further, there are cases where predetermined processing can be executed using dedicated hardware.

  Since the document management program according to the present invention can contribute to the improvement of the user interface in the thumbnail display, the industrial utility value is high.
