ABSTRACT:
A parallel image processing system comprises an image detection array of photodector elements, edge detection circuit including a number of edge detection elements for producing an output signal indicating detection of edge of the input image, and movement detection circuit including a number of movement detection elements each being supplied with output signals from a first group of the edge detection elements along a first signal path as an excitement signal and further from a second group of the edge detection elements along a second signal path as an inhibitory signal, for producing a movement detection signal indicating movement of the input image on the basis of comparison of the excitement signal and the inhibitory signal.
