PURPOSE:To enable the detection of the dynamic information of an image or a pattern and the alteration of signal processing content, by providing a light receiving cell, a sum signal output line, a transmission change-over means, a memory cell and a memory writing means in a substrate in a two- dimensionally integrated state. CONSTITUTION:The light receiving cell 2 provided on a substrate 1 detects an image or irradiation light pattern being a measuring object and a memory cell 5 stores and holds load information used in spatial parallel processing and controls the transmitting and blocking operation of a transmission change- over means 4 for transmitting the output signal of the specific cell 2 to a specific sum signal output line 3. The output line 3 receives the output signal from the cell 2 through the means 4 and the sum signal thereof is outputted to the outside of the substrate 1 or the signal processing circuit in said substrate 1. A memory writing means 6 writes load information in the cell 5. By this method, the dynamic information such as the moving speed of an image is suitably detected and measured and the moving speeds in x- and y-directions are changed over by the changing-over of load information to be outputted and operation of pattern matching is also enabled.
