要約(日本語)：This paper presents simple analog-digital motion detection circuits inspired by the vertebrate retina.  The unit circuits are designed with a focus on a simple, compact structure.  These circuits can be arranged in one or two dimensions, allowing the detection of both the direction and speed of movement.  Each unit circuit comprises two primary components: an edge detection circuit, modeled after the outer retina, and a motion signal generation circuit, based on the inner retina.  The proposed circuit was evaluated by the SPICE.  The proposed circuit can detect velocity of moving objects.  The measurement results of the integrated circuit with the 0.6 μm CMOS process showed that the proposed circuit can detect the edge and motion of moving objects.
