Abstract

In an image information retrieval network system having a file station storing a plurality of images to be searched in the form of compressed data by means of coding and at least one terminal station connected to the file station via a transmission line, the file station includes a processor for decoding compressed image data read from an image file to restore an original image, an image processor for processing the restored image data such as extracting a partial area thereof, and a coding processor for data-compressing the processed image data by means of coding. When a user at the terminal station designates a search condition, display mode, and control information for image processing, the file station reads the images satisfying the search condition from the image file, and causes the searched images to be subjected to the image processing designated by the control information. The processed image data are transmitted to the terminal station in the form of compressed data by means of coding.
