Abstract
An image processing system of the invention has a reader which reads out an image of an original, a page memory which stores image information of the original in the form of electric signals, a disk memory which stores part or all of the image information in the disk memory and also stores image processing information, an image processing section, a digitizer for the operator to input the image processing information, a CRT which displays input information or corrections in conversation language, a DMA controller, and a printer. The image processing system of the invention is capable of DMA transfer without the intermediacy of a CPU. Fewer addresses are required for readout of the image information from the memory, and high speed image processing is achieved.
