摘要
设计实现了一个在Blackfin533平台上的最小视频采集与显示系统。通过两个中断完成响应触发信号、视频帧采集、格式转换、显示等功能,并根据DSP结构对视频数据格式转换部分进行了优化。实验结果表明,该系统可获得更快的视频帧采集及显示速度。
The paper designed and realized a minimum digital video capture and display system based on Blackfin533 platform. Through two interrupts, the functions of burst signal response, video frame capture, format conversion, frame display were realized, and the part of video data format conversion was optimized according to the structure of DSP. The experimental results show that higher video frame capture and display speed is obtained.
