Abstract
This is a real time video signal processor for real time digital processing of video signals with a plurality of unit processors. All the unit processors are connected in parallel between an input bus and an output bus. Each unit processor consists of an input section connected to the input bus, a processing section for digital processing of video signals written into the input section, and an output section for supplying video signals processed by the processing section to the output bus. There is provided control sections for generating control signals to command what picture block of each frame is to be written into each unit processor and what picture block of each processed frame is to be outputted. Generally, each unit processor takes in a greater picture block than the picture block to be processed, and each processor independently accomplishes digital processing of the picture block assigned to it without communicating with any other unit processor.
