Information registering and retrieval system
First Claim
1. An image registering and retrieval system for converting a predetermined number of blocks of image information read from a document to image signals and registering or retrieving the image information, comprising:
- memory means having the predetermined number of first memories for storing the predetermined number of blocks of image information and having the predetermined number of second memories corresponding to the predetermined number of first memories for storing compressed data of the predetermined number of blocks of image information;
control means, operatively communicative with said memory means, having the predetermined number of compressing and restoring means corresponding to the predetermined number of first and second memories for compressing and restoring the image information in the predetermined number of first and second memories in response to retrieval and executing instructions input to the system, a first half portion of the predetermined number of blocks of the image information being compressed and stored into the predetermined number of second memories in a first sequence direction from a central portion of the document and a second half portion of the predetermined number of blocks of the image information being compressed and stored into the predetermined number of second memories in a second sequence direction from said central portion of the document where said first sequence direction is opposite to said second sequence direction, said first and second half portions of the predetermined number of blocks of image information are restored into the predetermined number of first memories in said first and second sequence directions respectively; and
display means, operatively communicative with said control means, for displaying the predetermined number of blocks of the image information simultaneous to and in said first and second sequence directions respectively as the image information is compressed and restored by the predetermined number of compressing and restoring means.

Abstract
An image registering and retrieval system includes a plurality of first memories for storing a plurality of blocks of image information, a plurality of second memories for storing compressed data from the plurality of blocks of the image information, a plurality of compressing and restoring sections that are provided for each block of the image information so that the image information is compressed or the compressed data is restored and a display device for displaying the image information. The plurality of compressing and restoring sections simultaneously process the image information.
