面向CMOS图像传感器的噪声抑制研究进展
Research Progress on Noise Suppression for CMOS Image Sensors
摘要
Abstract
As a typical solid-state imaging sensor,CMOS image sensor(CIS)employs a standard CMOS process to integrate pixels and signal processing circuits into a single chip.Noise in the design process of CIS introduces random variations to the image,bringing about adverse effects on the image quality and signal-to-noise ratio,particularly under low-light conditions.It is necessary to take measures to minimize the effects of noise as much as possible in order to improve the imaging quality of CIS.The architecture and typical noise models of CIS are reviewed,the latest progress of various noise suppression methods and comparison of various indexes from both pixel units and readout circuits are analyzed in detail,and the possible development direction of low-noise CIS is discussed and outlooked.关键词
