PROBLEM TO BE SOLVED: To make a chip flexibly conformable and adjustable to different applications, enable bandwidth compression of a digitized image, perform correlation processing of a present image and a just preceding image through a digital processing on a chip, and optimize design to high density CMOS structure. SOLUTION: In a chip 100 of a single CMOS integrated circuit, an optical cell array 112 takes in an image and forms a corresponding analog signal, and a converting circuit 120 converts the analog signal into a digital signal. A correlation circuit 140 processes the digital signal, and forms a result plane having a minimum value showing the optimum image displacement between the taken-in image and the just preceding image. An interface circuit 160 formats the digital signal from the converting circuit 120, imparts compatibility to signal communication to a previously selected device, and sends out the signal.
