Abstract

PURPOSE:To efficiently retrieve an objective picture by changing the number of pages to be thinned to display information at the time of thinning and displaying information by a display means or during the display. CONSTITUTION:When the document preserved in a magneto-optical disk device 11 will be successively displayed, the number of pages which are skipped for display is set. That is, when the indication to skip two pages is inputted, a third page is displayed from the magneto-optical disk device 11. When an operator depresses a key to indicate the display of the next picture, the next picture, namely, a sixth page is displayed. Thus, page intervals at which the display is updated is arbitrarily changed to easily find out the objective page picture.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an information retrieval device, and more particularly to an information retrieval device that stores page-by-page information and searches for the information.

[Prior Art] In recent years, with the development of large-capacity storage media such as magneto-optical disk devices, it has become possible to store a large number of images with a relatively large amount of information. Therefore, it has become possible to read and register an existing document or part of a newspaper as an image, and search for a desired document image from a group of these document images. With the development of laser beam printers and the like, it has become possible to quickly output search results in high definition.

By the way, when there are multiple document image candidates obtained from the search results, or when the obtained document image consists of several pages, the operation of finding out where the target page image is among them must be done manually. It won't happen.

[Problem to be solved by the invention] Normally, images are displayed page by page and the target page image is searched for. If it's ten pages away, you'll have to waste your nerve trying to find it. That is, from the viewpoint of improving work efficiency and reducing the burden on the operator, problems remain.

The present invention has been made in view of such problems, and it is an object of the present invention to provide an information retrieval device that makes it possible to efficiently search for a target image.

[Means for Solving the Problem] In order to solve this problem, the present invention includes the configuration shown below.

That is, an information retrieval device that stores information in units of pages and searches for the information includes a display unit that thins out and displays the information in units of pages, and a changing unit that changes at least the number of pages to be thinned out in the display unit. .

[Operation] In the configuration of the present invention, when the information is thinned out and displayed on the display means, or while the information is being displayed, the number of pages to be thinned out is changed by the changing means, and the information is displayed.

[Examples] Examples according to the present invention will be described in detail below with reference to the accompanying drawings.

1. Explanation of the outline of the configuration (FIG. 1)> FIG. 1 shows the outline of the configuration of the electronic filing system in this embodiment.

In the figure, 1 is a CPU that controls the entire system. 2
1 is a memory, which is composed of a program area 2a storing programs related to control processing of the CPU 1 and a work area 2b for various processing. In addition to programs related to various processes (for example, search processing, etc.), this program area 2a also stores programs related to the flowchart of FIG. 3, which will be described later. 3 is a floppy disk, and 4 is a hard disk. The floppy disk 3 is mainly used for personal use, and the hard disk drive is used when processing common data. Reference numeral 5 denotes an FD/HD controller that controls the floppy disk 3 and hard disk 4 to exchange data. Further, 6 is a printer that forms an image, and 7 is a scanner that reads an original image. Reference numeral 8 denotes an S/P interface, through which print data is output to the printer 6 and images are input from the scanner 7.

9 is a 5C8I interface which is a general-purpose interface, and a magneto-optical disk device 11 (including its controller 10) is connected to this interface. Incidentally, this magneto-optical disk device 11 also stores various kinds of information to be searched in the embodiment. 1
A keyboard 2 is used to input various characters and instruction information, and a pointing device (mouse) 13 is connected thereto. Then, the manually entered key information and the movement information from the pointing device 13 are output as serial data. 14 is a serial interface that inputs this serial data and converts it into corresponding parallel data. 15 is a pit manipulation unit that transfers image data or performs bit control such as rotation.
BMU), 16 is a character font storage unit that stores patterns corresponding to character symbol codes, 17 is a VRAM that develops display images as image data, 18 is a VRAM
A CRT 17 visualizes and displays the expanded image data, and a companding unit 19 compresses the image or expands the compressed data.

Note that these various components are electrically connected via a bus 100 (including an address bus, a data bus, and a control bus).

Further, in the above-described configuration, when registering information, the image read by the scanner 7 is once compressed by the companding section 19, and then registered in the magneto-optical disk device 11 together with keywords such as the corresponding document name. Then, when searching, the relevant images are extracted by inputting the necessary keywords. Also, since the scanned image is compressed,
The data is expanded in the companding section 19 and then expanded in the VRAM 17 for display.

2. Explanation of Outline of Processing (FIG. 2)> The content of processing for displaying search results in this embodiment in the above-described configuration will be described below.

In the following explanation, it is assumed that the information including the purpose information has already been narrowed down to some extent.

Now, when sequentially displaying documents stored in the magneto-optical disk device 11, first, the number of pages to be displayed is set. For example, when an instruction to skip two pages is input, the third page is first displayed from the magneto-optical disk device 11, as shown in FIG. Then, when the operator presses a key instructing to display the next screen, the next screen, that is, the sixth page is displayed.

Thereafter, each time this key is pressed, two pages are skipped and displayed. Note that, at this time, if a key instructing to display the previous screen is pressed, the screen will be skipped in the same way.

In this way, when the target page is displayed, the user presses the "5TOP" key on the keyboard 12. Furthermore, since two pages are skipped, it is possible that the target page is among the skipped pages. At this time, since at least the pages before and after the target page are displayed, it is possible to recognize that the displayed image is close to the target page image. Therefore, at this time, an instruction to eliminate the number of skips (or to reduce the number of skips) is input. Thereafter, when keys related to next screen display and previous screen display are pressed, page images are displayed based on the changed skip number.

Further, in this embodiment, when no key press is detected for a predetermined period of time, the display is automatically updated. This makes it possible to be free from manual key operations until at least the vicinity of the target page image is displayed.

Description of Processing Procedure (FIG. 3) Based on the above-mentioned principle, the control processing procedure of the CPU 1 of the embodiment will be explained with reference to the flowchart of FIG.

First, in step S1, the number of pages to be skipped is set. Then, in step S2, the image is skipped by the set amount, and in the next step S3, the corresponding image is read from the magneto-optical disk device 11, developed in the VRAM 17, and displayed. After one page of images has been displayed in this way, in the next step S4, it is determined whether or not there has been an input from the keyboard 12. If no key human power is detected, the process proceeds to the next step S8, where it is determined whether a predetermined period of time has elapsed since the image display, and until the elapsed period elapses, the process proceeds to step S8.
Repeat the determination process in step 4. At this time, if no key force is detected after a predetermined period of time, the process returns to step S2 and the display is automatically updated.

Now, when key human power is detected in step S4,
Proceeding to step S5, the input key is the display update key (
It is determined whether the key is the next screen display key or the previous screen display key. When it is determined that this key has been pressed, the process proceeds to step S in order to read the image with the previously set skip number and skip direction.
Return to 2.

If the key is other than the display update key, the process proceeds to step S6, where it is determined whether the key is related to changing the number of skips. If it is determined that the key is related to changing the number of skips, the process returns to step Sl.

Further, if the key is not related to changing the number of skips, the process advances to the next step S7, and it is determined whether the key is the "5TOP" key. Then, when it is determined that the "'5 TOP" key is pressed, that is, when the purpose information is displayed, the above-mentioned processing is completed. Note that when any other key input is detected, the input is ignored and the process proceeds to step S4.
Return to

As described above, according to this embodiment, the page interval at which the display is updated can be arbitrarily changed, so it becomes easy to search for the target page image. In particular, when the page image to be updated is a long text consisting of multiple pages of document information, it becomes possible to search for the desired page from among them extremely quickly, and the burden on the operator is reduced. becomes possible.

As a specific example of setting the number of skip pages, the following operations can be considered.

■You literally enter the number of pages you want to skip using the keyboard.

(2) When keys related to next screen and previous screen display are pressed, the display is updated one page at a time, and when this key is pressed together with a predetermined function key, two pages are skipped. Then, you can freely change the number of skips in combination with other function keys.

However, other modifications may be made within the scope of the claims of the present application. Therefore, the invention is not limited to this example.

[Effects of the Invention] As described above, according to the present invention, it becomes possible to quickly search for desired information with a simple operation.
