摘要
介绍了CCD143A黑参考像元实现“AGC”的方法。此种方法,不仅提高了系统的稳定性和测试精度,同时简化了电路结构,并充分利用了CCD的分辨率资源。合理利用CCD的辅助像元给信号处理带来极大的方便。
This paper introduces a method which completes‘AGC’with the help of black reference pixel CCD143A. The method simplifies circut structure,which not only enhances the system stability and test precision ,but also adequately utilizes resources of CCD resolution .In addition, using supplementary pixels reasonably will benefit signal processing with great convenience.
