摘要
根据CCD输出视频信号的特点,分析并设计了CCD相机视频信号处理方案;使用集成了相关双采样电路(CDS)、增益控制电路(AGC)、箝位电路、模数转换器(ADC)等功能的CCD信号处理芯片TDA8783对视频信号处理电路进行了详细设计,对该处理过程进行了详细的研究和分析。最后,简单总结了视频处理电路中应注意的问题。
Based on the character of CCD video signal, the project of CCD camera video signal processing was analyzed and designd. TDA8783, CCD signal processing chip was adopted, to design the circuit. The device includes a correlated double sampling circuit(CDS), AGC and a Analog-to-Digital Converter (ADC) together with its reference voltage regulator. The process was studied and analyzed in this article. Finally, the problem of video signal processing circuit was simply summarized.
