摘　　要：用EZ-USB FX2接口控制器,建立CMOS数字图像传感器与PC机之间的USB2.0数字视频信号传输通道,实现从摄像头到PC的高速传输;利用流媒体开发包DirectShow,实现视频的捕捉与显示;再利用Visual C++软件编程对PC端采集到的图像进行分析,详细讨论了程序设计过程。从而构成视频流实时采集与显示,图像MTF、亮度、疵点等参数的检测与分析系统。The high speed transferring video signal from camera to PC was achieved, with EZ- USB FX2 and CPLD chips as video signal transfer channel between CMOS image sensor and PC. Using DirectShow, the video signal could be grabbed and displayed. The quality of the image that captured from camera in personal computer was given by VC ＋＋ programming, such as MTF, shading, particle and so on. The programming technology was also discussed.
