Research of Noise Suppression for CMOS Image Sensor

Noise problem has a strong impact on the performance of sensor, especially in the field of aviation remote sensing. In this paper, the structure difference of CMOS and CCD image sensor is analyzed, and the noise affection and reasons are researched for CMOS image quality. Then the effective methods for each type of noise suppression are presented to improve the imaging capability. These researches provide theoretical support for the development of CMOS image sensor technology, and give a chance to use in the field of aviation remote sensing.
