Abstract
An image processing system is disclosed which includes: a control computer which has a CPU and a main memory therein; and an image memory section which is connected to the CPU through an interface and which has an image memory for digitally storing image data, a memory controller and an image processor. A memory area as part of the main memory is independently allocated to store as a register area data transferred through a privately leased data bus which bypasses the interface between the control computer and the image memory section. When random access operation of the image data with respect to the image memory is performed, the data transfer between the CPU and the image memory section can be performed through the memory area (register area) and the special data bus without going through the interface.
