Title: Image processor

Abstract: An artificial retina chip in a camera unit of an image processor according to the present invention converts an input image taken by the camera unit to analog signals, and outputs an image signal differential between each dot in a sensor-cell array in the artificial retina chip and a specific standard dot, as an analog signal. A signal converter converts the analog signal to binary digit, and stores the converted signals. When converted signals for one input image are stored, the signal converter outputs the converted signal to an identification unit as a digital signal. Namely, the data output from the camera unit is represented by the analog signal indicating the image signal differential between the dots, and the data output from the signal converter is represented by binary digit which is converted from the analog signal. Accordingly, the amount of the transmitted data is decreased.
