Description

  The present invention relates to a document processing apparatus capable of easily displaying a desired page in a document on a screen, and more particularly to page switching display using thumbnail images.

The document displayed on the screen based on the electronic data has various advantages such as easy editing, easy copying, and handling a large amount of documents in a compact manner. Compared to a document printed on paper, it is difficult for the user to intuitively understand how many pages the document is composed of, and it is easy to find and view the desired page contained in the document. There is a drawback that it is difficult to do.
Therefore, in a document processing apparatus that displays a document image on a screen based on document data, when the document includes a plurality of pages, the user can recognize that the document includes a plurality of pages, or the user can It is an important issue to improve the operability of handling a document on the screen so that the page image can be easily displayed on the screen.

Under these circumstances, various techniques have been developed to improve the operability of documents on the screen, and document processing apparatuses shown in FIGS. 8 and 9 are known (DocuWorks 5 manufactured by Fuji Xerox Co., Ltd.). 0.0.)
In the document processing apparatus shown in FIG. 8, when the image of the document 2 consisting of a plurality of pages is displayed on the screen 1, the edges of the other pages 2b, 2c, and 2d are protruded from the page 2a that is the head of the document. Overlapping display expresses that the document 2 is composed of a plurality of pages. Then, the cursor 3 that is moved by the user operation is moved onto a desired page so that the page number “2” is displayed in the vicinity of the cursor when the cursor 3 is positioned on the second page 2b. The page number 4 can be visually confirmed on the screen 1, and the display can be switched to the state in which the page is set to the top page when the user clicks the mouse.

  In the document processing apparatus shown in FIG. 9, the area 1a for displaying the image of the document 2 composed of a plurality of pages 2a to 2d on the screen 1 and the thumbnail images (reduced images) 5a of these pages 2a to 2d as described above. To 5d are provided, and the thumbnail images 5a to 5d allow the user to grasp the description contents of the pages 2a to 2d included in the document 2. Then, when the user moves the cursor 3 onto a desired thumbnail image and performs a click operation, the display of the area 1a can be switched to the state where the page is the top page.

As an invention for improving the convenience of browsing information using thumbnail images, an invention has been proposed in which image data acquired from a Web page in a WWW environment is processed into thumbnail images and the thumbnail images are displayed (Patent Literature). 1).
JP 2004-70809 A

  Various improvements have been made by the document processing device in order to improve the operability of handling a document including a plurality of pages on a screen. However, further improvement in operability is desired.

For example, in the example shown in FIG. 8, it is possible to easily grasp that the document 2 includes a plurality of pages 2a to 2d, and display on the page while confirming the page number 4 of the desired page. Switching can be performed easily, but when the user does not know the page number of the desired page in advance, it may be necessary to perform complicated operations such as sequentially switching the display of each page to find the desired page. It was.
Further, for example, in the example shown in FIG. 9, the list display of the thumbnail images 5a to 5d allows the user to easily find a desired page and switch the display to the page, but the size is limited. Since it is necessary to provide the thumbnail image list display area 1b on the screen 1, the area 1a for displaying the page for performing operations such as browsing and editing becomes narrow, and the operability for the actual page is impaired. was there.

The present invention has been made in view of the above-described conventional circumstances. A document can be displayed on a screen so that a sufficient display area of a document page can be secured on the screen and a user can easily find a desired page. It is intended to be displayed.
Another object of the present invention is to display a document on the screen so that the user can easily switch the display to a desired page found by the user.

In the document processing apparatus according to the present invention, when the operation means accepts an operation input from the user and the operation determination means determines that a thumbnail display instruction or a thumbnail switching instruction is input by the user operation, the display processing means displays the thumbnail display. The thumbnail image of the document page displayed on the screen is displayed on the screen in response to the input of the instruction, and the thumbnail image of the other page of the document is displayed on the screen in response to the input of the thumbnail switching instruction. Switch to and display.
Here, in the present invention, the display method for a document including a plurality of pages may be a method in which each page is displayed on the screen one by one or, as shown in FIG. 8 or FIG. A method of displaying the edges of the page in an overlapping manner may be used.
The thumbnail image may be generated and displayed by the document processing apparatus as necessary, but may be generated in advance and acquired and displayed as necessary.

Therefore, the contents of each page, which is different from the page corresponding to the displayed page image, can be grasped by the thumbnail image, and the desired page can be easily turned by switching the thumbnail image of each page and turning the page. To find out. In addition, since the thumbnail images are switched and displayed, a large screen area is not used for displaying the thumbnail images, so that a display area for the page image can be secured with a sufficient size on the screen.

  Here, in the present invention, the operation determination unit further determines that a page switching instruction is input by a user operation from the operation unit, and the display processing unit issues a page switching instruction in a state where the thumbnail image is displayed on the screen. Depending on the input, an image of a page corresponding to the thumbnail image may be displayed on the screen, whereby a desired page found by the thumbnail image can be easily displayed on the screen.

  Such display switching of thumbnails and pages can be realized by various operation methods performed by, for example, a mouse operation or a keyboard operation. ), And a thumbnail switching instruction is input by pressing a second button on the keyboard (for example, one or both of the left and right arrow keys), and a page switching instruction is the first button. It is preferable that the input is performed by an operation of releasing the pressing of the button, whereby a desired page can be found and switched to display of the page by a few button key operations.

In the present invention, the position for displaying the thumbnail image may be set at any position on the screen, but it is preferably displayed at the corner of the screen that does not interfere with the display of the page image.
The present invention is also realized as a program for realizing such a document processing apparatus by a computer and a document processing method that can be implemented by such a document processing apparatus.

  According to the present invention, since thumbnail images of pages included in a document are sequentially switched and displayed on the screen, the user can easily find a desired page in a state where a display area of the page image is sufficiently secured on the screen. Therefore, it is possible to realize an operation environment in which display switching to a desired page can be easily performed.

FIG. 1 shows the configuration of a document processing apparatus according to an embodiment of the present invention. Hereinafter, the present invention will be described in detail based on the embodiment.
The document processing apparatus 10 of this example includes a screen 11 such as a liquid crystal panel for displaying a document image, an operation means 12 such as a mouse and a keyboard for receiving an operation input from a user, a file memory 13 for storing and holding document file data, a file memory 13, a reading unit 14 that reads out the document file data held therein, a thumbnail generation unit 15 that generates a thumbnail image of the page by performing a reduction process based on the page data included in the document file data, and an operation unit 12. Operation determining means 16 for determining that either a thumbnail display instruction or a thumbnail switching instruction or a page switching instruction has been input by a user operation from, a thumbnail image display and switching process, and a page image display switching corresponding to the thumbnail image Display processing means 17 for performing processing .

  Here, each of the above functional units may be configured by hardware, but in this example, thumbnail display is performed by causing the computer constituting the document processing apparatus 10 to execute the program according to the present invention. Operation determining means 16 for determining that either an instruction, a thumbnail switching instruction or a page switching instruction has been input, and a display process for performing a thumbnail image display and switching process and a page image display switching process corresponding to the thumbnail image Means 17 are configured.

For example, as shown in FIG. 2, the document file data stored and held in the file memory 13 includes the file ID 21 for identifying each document and the attribute information such as the number of pages 22 included in the document. The page ID 23 for identifying the page is associated with the page data 24 that is actual data of the page.
In this example, the thumbnail generation means 15 generates a thumbnail image of the page based on the page data 24. However, the thumbnail image data is attached to each page data 24, and the thumbnail image data And a thumbnail image may be displayed on the screen 11.

In the document processing apparatus 10 of this example, by performing processing as shown in FIG. 3, as shown in FIGS. 4 to 7, the thumbnail image 34 is displayed and switched on the screen 11, and the corresponding page 32a is displayed. Switch the display.
When the specification of the document file input from the operation means 12 is received by the user (step S1), the reading means 14 reads the document file data of the corresponding file ID 21 from the file memory 13 (step S2).

Next, the display processing means 17 displays the first page 32 of the document on the screen 11 as shown in FIG. 4 based on the read document file data (step S3). Note that reference numeral 33 denotes a cursor.
Here, in this example, even when the document includes a plurality of pages, one page is displayed on the screen. However, as shown in FIG. 8, pages other than the first page may be displayed in an overlapping manner.

  When the operation determining means 16 detects that the user has input a thumbnail display instruction from the operating means 12 (step S4), the thumbnail generating means 15 is based on the page data 24 of the page 32 displayed on the screen 11. A thumbnail image 34 is generated (step S5), and as shown in FIG. 5, the generated thumbnail image 34 is displayed at a corner that does not overlap the display page 32 of the screen 11 (step S6).

When the operation determination means 16 detects that the user has input a thumbnail switching instruction from the operation means 12 (step S7), it is based on the page data 24 of the next (or previous) page 32 displayed on the screen 11. Then, the thumbnail generation unit 15 generates a thumbnail image 34a (step S5), and the thumbnail image 34a generated by the display processing unit 17 is displayed on the screen 11 in place of the previous thumbnail image 34, as shown in FIG. (Step S6).
Therefore, every time the user inputs a thumbnail switching instruction, the thumbnail images of the pages included in the document are switched and displayed one page at a time in descending or ascending order.

When the operation determination unit 16 detects that the user has input a page switching instruction from the operation unit 12 (step S8), the display processing unit 17 first displays the thumbnail-displayed page 32a as shown in FIG. The page 32 is displayed on the screen 11 (step S9), and the process returns to step S4.
Therefore, when the user inputs a page switching instruction, the page 32a displayed as the thumbnail image 34a is displayed on the screen 11.

  Here, in this example, input of a thumbnail display instruction and a page switching instruction is assigned to the first button (for example, Alt key button) of the keyboard 12, and the second button (for example, left and right arrow key buttons) of the keyboard 12 is assigned. Is assigned an input of a thumbnail switching instruction. More specifically, a thumbnail display instruction is input when the Alt key button is kept pressed, a page switching instruction is input when the Alt key button is released, and the right arrow key When the button is pressed, thumbnail images are paged in descending order, and when the left arrow key button is pressed, thumbnail images are paged in ascending order.

  Therefore, the user presses the Alt key button to display a thumbnail image on the screen, and operates the arrow key button while pressing the Alt key button to page the thumbnail image in the descending or ascending order, and then the desired page. When a thumbnail image of a desired page is displayed on the screen and a series of operations such as releasing the Alt key button are performed, the desired page can be found and displayed on the screen.

In this example, the left arrow key button and the right arrow key button can be used to page forward in both ascending order and descending order, but only one of the arrow key buttons can be in ascending order or descending order. You may enable it to perform page feed in any one direction.
The above instruction input may be performed by assigning it to another key button of the keyboard, and the above instruction is input by a mouse click operation or an operation using an operation menu displayed on the screen. You may do it.

In the above example, the thumbnail image is displayed at the corner of the screen 11 that does not interfere with the display of the page image 32. For example, the thumbnail image is displayed near the cursor 33 or at a position designated by the cursor. May be.
In the above example, thumbnail images are generated when display is necessary. For example, when a document to be displayed is specified, thumbnail images of all pages in the document are generated. It is also possible to prepare and acquire thumbnail images as required for display.
