Eye-RIS是视觉系统家族的名称，该系列视觉系统是为使用CMOS技术的单芯片集成而构思的。Eye-RIS系统采用仿生体系结构，其中图像采集和处理真正混合在一起，处理本身分两个步骤实现。在第一步，由于集成在传感器附近的专用电路结构的汇聚，处理是完全并行的。这些电路结构基本上处理模拟信息。第二步，利用数字处理器对数字编码的信息数据进行处理。总体而言，处理结构类似于自然视觉系统，在视网膜(第一层)进行并行处理，当信号从视网膜向上传输到视觉皮质时，信息量会显著减少。本章概述了Eye-RIS系统的概念及其主要组件，并提供了实验数据来说明其实际操作。
Eye-RIS is the name of a family of vision systems which are conceived for single-chip integration using CMOS technologies. The Eye-RIS systems employ a bio-inspired architecture where image acquisition and processing are truly intermingled and the processing itself is realized in two steps. At the first step processing is fully parallel owing to the concourse of dedicated circuit structures which are integrated close to the sensors. These circuit structures handle basically analog information. At the second step, processing is realized on digitally-coded information data by means of digital processors. Overall, the processing architecture resembles that of natural vision systems, where parallel processing is made at the retina (first layer) and significant reduction of the information happens as the signal travels from the retina up to the visual cortex. This chapter outlines the concept of the Eye-RIS system and its main components and presents experimental data to illustrate its practical operation.
