| Abstract: | The principle structure of a trilinear CCD is briefly introduced in this paper. According to the signal characteristic of its output videos and system requirement, the synthesized processing methods are needed to be implemented, including correlation double sample, programmable gain control, and line calibration, etc. TDA8783 is a special purpose video signal processor for CCD including above-mentioned functions, and the performance is excellent. The implementation method is explained in detail and is succe... |
