摘　　要：为提高CMOS工作性能,根据CMOS像素单元的基本构成,对CMOS中引起固定图形噪声的原因进行了较完整的分析,给出了引起固定图形噪声的两个重要原因。根据引起固定图形噪声原因的各自特点,提出了两种常用的固定图形噪声处理技术,使得CMOS器件在实际应用中,为追上CCD传感器画质的性能,提供了理论基础和实践经验。In order to improve CMOS working performance based on the basic constructors of CMOS pixel units,the reasons of stable graphic noise and illustrate toe of them have been analysed. Put forward kinds of stable graphic noise processing technology according to separate characteristics of the causes of stable graphic noise, which provide theoretic knowledge and practice experiences to acquire the performance that can be compared to the picture quality of CCD sensor.
