| Abstract: | Based on analyzing a CCD video signal processing system,a array CCD Video Signal Processing system using TDA8783 as the core and peripheral hardware accessory circuit as the assistant was designed.The time simulation of the system was successfully fulfilled,and the associated debugging of hardware and software were accomplished.The results of the test indicated that the system was stable and reliable.This design has good reference value for miniaturization design about continuing detector. |
