Abstract

PURPOSE:To easily retrieve image information by producing previously the information on the table of contents of a document to display the image information on plural pages at a time. CONSTITUTION:Image information obtained by scanning a document by a scanner 1 is recorded on an optical disk device 2 as document information via a print memory 5. This document information is reduced by a CPU 4 in response to the CRT picture of a display part 7 and recorded on the disk 2 as the reduced document information for retrieval via a display memory 3. Then the reduced document information is reduced again by the CPU 4 so as to be displayed on the CRT screen of the part 7 by an amount equal to plural pages and then recorded on the device 2 via a memory 6 for table of contents. As a result, the desired information is retrieved in a short time out of a large quantity of information by detecting the information on the table of contents of the document and without detecting directly the document information.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an image storage and retrieval device used for optical discs and the like for retrieving a large amount of information.

BACKGROUND OF THE INVENTION Conventionally, this type of image storage and retrieval device has a document file of images corresponding to print information, and when searching for a document, displays a summary of the content and whether or not it is the desired information on a CRT, and displays the desired information. If so, print the image file for print information.

Problems to be Solved by the Invention However, in the above-mentioned conventional image storage and retrieval device, the CR
Since only one page's worth of information can be displayed on the T, there is a problem in that it takes time to search for truly desired information from among multiple pages of information.

SUMMARY OF THE INVENTION The present invention aims to solve these conventional problems, and provides an image storage and retrieval device that allows users to quickly and accurately search for desired information from a large amount of information. That is.

Means for solving the problems and the technical means of the present invention to solve the above problems are to provide document information corresponding to print information, and to display this document information on a display section (reduced size for search). An optical disk device capable of storing document information and reduced document table of contents information in separate areas so that the reduced document information can be displayed in multiple pages on a display unit, and input/output of the above three pieces of information to and from this optical disk device. It is equipped with the means.

Effects With the above-described configuration, the present invention allows searching by looking at document information in which multiple pages of image information are displayed at once, without directly searching for document information. You can search for exactly the information you want in a short time.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a scanner that optically scans a target document and inputs image information written on paper to a print memory 5 to be described later. 2 is an optical disk device that stores document information for table of contents, document information for search, and document information for printer. 3
is a display memory that stores document information for searching. A CPU 4 has a reduction function and issues document input/output commands, search commands, and print commands. 5
is a print memory that stores document information corresponding to print information. , 6 is a memory for a table of contents, which stores document information for a table of contents. 7 is the display section (CPT)
Then, in response to a signal from the display memory 3, the document for retrieval is displayed. A printer 8 prints out a document in response to a signal from the print memory 5.

Next, the operation of the above embodiment will be explained. Scanner 1
The image information obtained by scanning the document is stored in the optical disk device 2 via the print memory 5 as document information. The document information is stored in the CPU
4, the document is reduced to correspond to the CRT screen of the display section 7, and stored in the optical disk device 2 via the display memory 3 as reduced document information for searching. In addition, this reduced document information is displayed on the CRT of the display section 7 by the CPU 4.
It is reduced in size so that a plurality of pages can be displayed on the screen, and stored in the optical disk device 2 via the table of contents memory 6 as document table of contents information. In this way, one piece of image information is separated into three parts and each part is recorded in a separate area of the optical disc device 2. As shown in FIG. 2, the storage area of the shared disk device 2 is divided into three areas: a print area, a reduced document area, and a table of contents area.The print area stores document information, and the reduced document area stores reduced document information and a table of contents area. records document table of contents information.

When all the document information is written in the print area, reduced document information is written in the reduced document area, and then document table of contents information is written in the table of contents area.

In this way, the image information is separated into three areas: the print area, the reduced document area, and the table of contents area, and the operation of writing them into the optical disk device 2 one after another is repeated, and a multi-page valve of image information is written to the document table of contents area, making it possible to search. becomes.

When searching for a desired document, first, the table of contents area is sequentially read out from the optical disk device 2 through the six table of contents memories according to a command from the cPU 4, and the document table of contents information is displayed on the display section 7, and the document that matches the desired information is displayed. If so, the reduced document area is read out from the optical disk device 2 via the display memory 3 in response to a command from the CPU 4, and the reduced document information is displayed on the display section 7. After confirming that this is the desired information, the document is read out from the print area of the optical disk device 2 via the print memory 5 according to a command from the CPU 4, and printed out by the printer 8.

As described above, according to the above embodiment, the document table of contents information is reduced so that the image information in the optical disc device 2 can be displayed on the display section 7 in a plurality of pages, and the document information is reduced so as to fit on the screen of the display section 7. Reduced document information for search, document information corresponding to print information 3
By recording the information in separate areas, when searching, it is possible to search for the desired information quickly and accurately from a large amount of information by searching the document table of contents instead of directly searching for the document information.

Effects of the Invention As is clear from the above, according to the present invention, document information corresponding to print information, this document information can be made to correspond to the display section (reduced document information for search, and this reduced document information can be displayed on the display section). The document table of contents information, which has been reduced so that multiple pages can be displayed at a time, is stored in separate areas of the optical disk device and read out.Therefore, when searching, searching for document table of contents information rather than searching for document information directly saves a large amount of information. You can search for exactly the information you want in a short time.
