Abstract

Analog complementary metal oxide semiconductor (CMOS) circuits for edge detection were proposed based on the vertebrate outer retina. A simple analog CMOS circuit for generating the motion signal, which inputs the edge signal, was also proposed based on the amacrine cell in the inner retina. The simulation results with the simulation program with integrated circuit emphasis (SPICE) showed that the proposed edge detection circuits can detect edge positions with a dynamic range of 5 decades. The simulation results with SPICE showed that the proposed circuit can generate the motion signal of the edge. A chip for processing a moving image in real time with the wide dynamic range can be realized by applying the proposed circuits
