摘要

介绍了一种采用标准CMOS工艺的中央凹图像传感器芯片。提出了一种用于有源像素传感器的光电电荷归一化方案及其相关电路。采用一种新颖的存取方案，将像素组装成一个多分辨率线性中央凹图像传感器芯片，以减少所需的模拟RAM单元的数量。局部空间分辨率随着与成像仪光轴的偏移而单调下降，类似于生物中央凹视觉。一个概念验证芯片已经被制造和测试。

An all CMOS foveal image sensor chip

A foveal image sensor chip that uses a standard CMOS process is presented. A new photo charge normalization scheme and its associated circuitry for use with active pixel sensors has been developed. The pixels are assembled into a multi-resolution rectilinear foveal image sensor chip using a novel access scheme to reduce the number of analog RAM cells needed. Localized spatial resolution declines monotonically with offset from the imager's optical axis, analogous to biological foveal vision. A proof-of-concept chip has been fabricated and tested.
