摘　　要：介绍了一种基于DSP视频采集系统进行设计的新方法。采用TI公司低端DSP芯片TMS320F2812(2812)实现了对CCD输出的标准视频信号的实时采集处理,通过帧积分的实时处理方法提高了采集图像的信噪比,系统具有结构简单、可靠性高、使用灵活和性价比高等优点。详细地描述了硬件设计、软件流程和2812全速AD转换的实现方法。Based on DSP,a new method to design a video acquisition system is proposed. Low-cost DSP TMS320F2812（2812） manufactured by TI corporation is adopted to acquire and process real-timely the standard video signal output of COD. The real-time processing of image accumulation is employed to improve the signal-to-noise ratio of images. It has some advantages such as simple structure, high reliability, high adaptability and high performance-cost ratio. The design of hardware, the flow of software and the method for full speed analog-to-digital conversion of 2812 are described in detail.
