Patent ID: 8351718

Claim:
An image data processing apparatus comprising a computer processor programmed with appropriate software to provide: a processing section that divides image data into a plurality of divided partial image data that are each of a prescribed size; a link information generating section that generates link information showing a mutual arrangement of each of the divided partial image data of the prescribed size; a compression section that compresses each of the divided image data to provide compressed partial image data; a compressed data storage section that provides for storage of each of the compressed partial image data compressed by the compression section in association with a corresponding segment of the link information into a storage device; a plurality of expansion sections that expand the compressed partial image data respectively; a speed acquiring section that acquires an output speed in which the image data ought to be outputted, transmitted from where the image data is outputted; a data controller that determines the number of the expansion sections that expand the compressed partial image data substantially simultaneously, based on a previously defined expanding speed of a single expansion section and the speed acquired from where the image data is outputted; the data controller further assigning each of the compressed partial image data to the determined number of the expansion sections, and operating the expansion sections to expand the compressed partial image data substantially simultaneously; an image data storage section that stores each of the expanded partial image data; an output section that outputs each of the stored partial image data to the outside of the image data storage section, wherein the data controller determines an area of the image data storage section, in which each of the expanded partial image data ought to be stored, and an output order of the stored partial image data in the image data storage section, based on the link information and the prescribed size of the partial image data, so as to restore the original image data.
