Abstract

Novel basic analog–digital edge detection circuits in this research were proposed based on the vertebrate retina. The vertebrate retina is a pre-processor for image processing in the brain and has superior functions such as edge detection and motion detection. The proposed circuit was evaluated by the simulation program with integrated circuit emphasis (SPICE) with the 0.6 μm complementary metal oxide semiconductor (CMOS) process. The simulation results with SPICE showed that the proposed circuits can operate normally. The test integrated circuit of the unit circuit was fabricated with a 0.6 μm CMOS process. The measured results showed that the unit circuit can detect the edge position. The test integrated circuits of one-dimensional array of unit circuits were fabricated with the same process. The measured results showed that the one-dimensional circuits can detect the edge position. In the future, the realization of a new vision sensor can be expected using the proposed circuit.

基于脊椎动物视网膜边缘检测的基本模数集成电路
本研究提出了一种基于脊椎动物视网膜的基本模拟-数字边缘检测电路。脊椎动物视网膜是大脑中图像处理的预处理器,具有边缘检测、运动检测等优越功能。采用集成电路重点(SPICE)仿真程序,采用0.6 μm互补金属氧化物半导体(CMOS)工艺对所提出的电路进行了评估。SPICE仿真结果表明,所设计的电路能够正常工作。采用0.6 μm CMOS工艺制作了单元电路的测试集成电路。实测结果表明,该单元电路能够检测出边缘位置。用相同的工艺制作了一维单元电路阵列的测试集成电路。实测结果表明,一维电路可以检测出边缘位置。在未来,可以期望使用所提出的电路实现一种新的视觉传感器。
