ABSTRACT:
An image processing system having a data compressor for selectively compressing image data, data storage for selectively storing the compressed data from the data compressor, a page buffer for storing the compressed data to be stored into and read out of the data storage, a data decompressor for selectively decompressing the compressed image data back into its original form, and a controller for controlling the operation of the compressor, data storage, and decompressor, in either of two modes, a processing mode in which the image data is compressed by the compressor, stored in the data storage, and decompressed by the decompressor, and a through mode in which the image data bypasses the compressor, the data storage, and the decompressor. The controller selects one of the two modes based the number of original documents bearing the image data, the number of copies of the original documents requested by a user, and whether editing is to be performed on the image data.
