ABSTRACT:
An image processing system includes data compressor for compressing image data, storing output data of the data compressor, data decompressor for decompressing the compressed data into the original image data and transferring the original image data to an image output section, and controlling the compressor data storage and decompressor whereby the image processing system compresses image data as fed from the image read device, stores the image data, reads the stored image data, decompresses the read out image data, and sends the decompressed image data to an image output section. The image processing system is improved in that at least one of output data bus line from the image read device or an output data bus line to the image output section has a bit-width larger than the number of bits constituting one pixel, and at least one pixel data is transferred every one clock cycle.
