中文摘要：

从基本电路原理出发,分析了采用互补金属氧化物半导体（CMOS）传感器获取图像的基本噪声来源,以及各噪声源的基本特性及其对输出图像的影响,讨论了不同系统结构CMOS图像传感器的图像噪声表现与相应噪声消除以及提高图像质量的系统解决方案,并进行了仿真验证.

英文摘要：

The system of a complementary metal oxide semiconductor（CMOS） image sensor and its operating mode are introduced.As noise problem is a key issue for image acquisition,a suitable noise model must be established.Here,we describe various noise sources,its fundamental factors,influences on image distortion and some different CMOS image sensor structures with their noise behavior,and then view general idea of noise reduction.Experiment results confirm the idea.
