摘　　要：在讨论传统的天文观测相机视频处理方式的基础上,设计了以高集成度的专用CCD视频信号处理芯片TDA8783为核心的相机视频处理电路方案。对所设计的视频处理电路进行了软硬件联调测试,仿真和实验的结果表明,电路系统运行稳定,噪声低,方案对后续观测相机系统的小型化具有较好的参考意义。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.
