一种CCD相机的视频处理电路设计与噪声分析
Design and noise analysis of video signal processing circuit for CCD camera
摘要
Abstract
In order to capture an image with high SNR by CCD camera,a design of application circuit for video processor TDA9965 is introduced. Its inner block diagram and working principle are described in brief. The quantization processing of the CCD analog video signal was successfully realized by taking a TDI CCD as a sensor,which can make the camera capture images in real time. The impact of the video circuit design on image SNR of camera is analyzed under the disturbance of power noise. The difference of image SNR under conditions of unreasonable circuit design and improved circuit design were calculated. The results of experiments show that reasonable design can enhance SNR of an image by 20 dB. The importance of reasonable video circuit design is illuminated consequently. It provided a technical foundation for the research of high-speed and high-SNR CCD camera.关键词
