Abstract
Abstract An image processing system constituted by a printer engine (3) corresponding to one or both of binary and multi-value data, and a plurality of memory devices (1a, 1b) for supplying a binary or multi-value video signal to the printer engine, and storing bit map data has a means (7) for connecting the plurality of memory devices (1a, 1b) to the engine (3). Binary or multi-value data is read out from an arbitrary memory device, two different binary data, two different multi-value data, or binary data and multi-value data are synthesized, and the synthesized data is printed. Processing, which is conventionally performed by a single memory device, can be separately performed by the plurality of memory devices, thus increasing the processing speed. Various processing operations such as binary-multi-value synthesizing processing can be easily performed.
