Abstract
PURPOSE:To improve processing capacity by connecting a data bus for transferring a binary image, outputting the binary image formed by the 1st processing circuit to the data bus and using the data bus for switching the processing function of the 2nd processing circuit. CONSTITUTION:An image input circuit 2 and an image output circuit 3 are connected to a data bus B1 to be usually used for many-valued images to input/ output many-valued image data between these circuits 2, 3 and an external circuit under control based upon a host CPU 1 to be a control means. The many-valued image on the bus B1 is stored in a many-valued image memory M1 or processed by the 1st many-valued image processing circuit P1. At the time of forming a binary image as the processed result of the circuit P1, the image is outputted to a binary image data bus B2, stored in a binary image memory M2 or processed by a 2nd binary image processing circuit P2. In this case, the binary image on the bus B2 is used as a binary image for switching the processing function of the circuit P2 and the circuit P2 is directly controlled by the binary image formed by the circuit P1 to execute parallel processing, so that the processing capacity can be improved.
