Method and apparatus for retrieving image data
First Claim
1. In an image filing system including image input process means for inputting image data representing an image to be processed, store means for storing the image data input by said input process means, retrieval means for retrieving image data stored in said store means, and a display having a predetermined display dot number for displaying image data retrieved by said retrieval means, a method of filing images data comprising the steps of:
- dividing image data representing an input image having a dot number larger than said predetermined display dot number into a plurality of partial images, representing in combination the entirety of said input image, at a fundamental unit equal to said predetermined display dot number;
producing compressed data by compressing each of the divided partial images;
predetermining position information of a distinguishable partial image among all of the divided partial images; and
storing said position information together with said compressed data of said divided partial images into said store means.

Abstract
A filing method and a system for filing image data operate to divide an input image having a dot number larger than a predetermined dot number of a display screen at a fundamental unit equal to the display screen size, to file the divided input images as a plurality of partial image data on an optical disk, and to retrieve the filed images at high speed. The division filing system includes an input image process device for compressing the divided partial image data, and an index generating device, such as a complexity detecting circuit, for extracting either position information of a distinguishable partial image, or address information among the divided partial images. An optical disk device stores either the position information or the address information as well as the compressed image data into an optical disk. The image retrieval process sequentially reads the compressed image data of only the distinguishable particular image from the optical disk, while referring the address information or the position information image.

20. In an image filing system including an image data input device, store control means for storing the image data inputted by said input device into an optical disk, retrieval means for retrieving image data stored in said optical disk, and a display screen having a predetermined display dot number for displaying retrieved image data, a method of filing image data comprising the steps of:
-
dividing all of the input image data representing an input image into a plurality of partial images at said fundamental unit in response to an input of image data for an input image which is larger than said display screen can display at one time; compressing each of the partial images and temporarily all of the partial images as compressed data; extracting position information of a distinguishable partial image among the respective divided partial images; and storing the extracted position information together with the compressed data for all partial images into said optical disk.
