Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an information retrieval method for an information file device that records and stores a large amount of image information such as documents, drawings, etc. and can arbitrarily search the image information. .

(b) Conventional technology In this type of information file device, the original is optically
The image information read and formed by dimensional scanning is compressed and stored in a storage device, for example, an optical disk. The image information stored on the optical disk is optionally retrieved, decompressed, and then output to an output device, such as a CRT display device or a printer device.

In such an information file device, an information retrieval means for retrieving arbitrary image information from an optical disc is essential. Such information retrieval means generally stores search information (keywords, file names, etc.) corresponding to each piece of image information in a search file (or an optical disk storing image information), and searches for arbitrary search information when searching for information. A search file is searched by inputting a search file, and desired image information is searched from an optical disc based on the searched contents.

By the way, as the amount of image information stored on an optical disc increases, the amount of search information also increases. Therefore, during information retrieval, it becomes difficult to accurately input optimal search information corresponding to desired image information. In such a case,
Search information considered to be optimal is input sequentially, and each time the search information is input, image information is sequentially searched and sequentially output to an output device.

That is, it is necessary to repeatedly perform different operations of inputting search information and confirming searched image information.
Very annoying.

A technique for eliminating such troublesome search operations is disclosed in Japanese Patent Laid-Open No. 58-87660. this is,
Means for accumulating reduced information obtained by reducing image information to be registered is provided, a table of contents is created from a plurality of such reduced information, and this table of contents is used to search for image information. Therefore, by visually viewing a plurality of pieces of reduced information representing the contents of the image information, it is possible to perform the search while grasping the contents of the target image information to some extent, thereby facilitating the search operation.

(c) Problems to be solved by the invention The hot topic is that such a configuration requires a means for accumulating multiple pieces of reduced information, and no matter how much reduced information is, the above-mentioned The amount of information is extremely large compared to the search information. Therefore, storage means with a very large capacity is required.

An object of the present invention is to facilitate the search operation even though the search is performed using the above-mentioned search information.

(d) Means for Solving the Problems The information retrieval method of the information file device of the present invention stores search information that has been continuously searched from a search file storing a plurality of pieces of search information in a memory circuit, and then The present invention is characterized in that image information is continuously searched from an information file based on search information stored in a memory circuit and sequentially outputted to an output device.
