Patent ID: 6876465

Claim:
An image processing system, comprising: a memory for storing image data of a plurality of pages; a compressor for compressing input image data; writing means for writing a set of image data of a plurality of pages compressed by said compressor into said memory in sequence; a first controller which executes a reading of the set of stored image data from said memory and an image processing thereof in sequence; a second controller which executes a re-reading of the set of stored image data from said memory and an image processing thereof in sequence; a first detector for detecting insufficiency of empty capacity of said memory based on a capacity, of image data of one page compressed at a predetermined compression rate; and a third controller which, in the event that insufficiency of empty capacity of said memory is detected by said first detector during the writing of image data into said memory by said writing means, continues the image processing by said first controller by writing new image data by said writing means after a termination of the image processing of the image data of at least one page stored previously by said first controller; and a second detector which detects an occurrence of an overwriting of the new image data on the stored image data at the time of writing the new image data by said third controller.
