摘　　要：探讨了以TMS320DM642DSP为核心器件基于CMOS图像传感器MT9T001的一种数字图像采集系统.介绍了TMS320DM642视频口和图像传感器的工作模式以及通过视频口的原始捕捉模式实现的TMS320DM642和MT9T001的无缝连接方式,给出了关键参数的调试方法,经测试该设计是一种十分有效的图像采集方式,系统具有结构合理、算法灵活、图像质量好的特点.This paper examines the realization and application of DSP in video and image process. With TMS320DM642 as the core chip, and MT9T001 as its base, the image capture system of CMOS image sensor has a bright prospect for the application because of its simple design, reasonable price, and good quality image. This paper describes the work mode of TMS320DM642 video port and the image sensor, introduces the realization of the glueless interface through the raw capture mode of the video chip, and puts forward debugging methods for key parameters. After several trials, the capture can reach 45 fp/s when the resolution is 720 × 576. Facts have proved that this system is effective in image capture, with the characteristics of reasonable structure, flexible algorithm, and good image quality.
