基于脊椎动物视网膜内外层的信息处理机制，提出了一种简化的目标边缘信号形成和运动信号产生模型。基于该模型设计了模拟MOS集成电路。仿真程序与集成电路强调（SPICE）的仿真结果表明，在一个广泛的动态范围内的视网膜外电路和生成的运动边缘的速度信号在视网膜内电路的本地适应的性能。初步的实验结果表明，在一个给定的输入范围内的视网膜外电路和运动脉冲信号的产生在视网膜内电路的局部适应。
A simplified model was proposed for the formation of edge signals and generation of motion signals of a target based on the information processing mechanisms of outer and inner retinas of a vertebrate. Analog metal-oxide-silicon (MOS) integrated circuits were designed based on the model. Simulation program with integrated circuit emphasis (SPICE) simulation results showed the performance of local adaptation over a wide dynamic range in the outer retinal circuit and generation of the velocity signal of a moving edge in the inner retinal circuit. Preliminary experimental results showed local adaptation in a given input range in the outer retinal circuit and the generation of motion pulsed signals in the inner retinal circuit.
