基于STC89C516RD的视频信号采集与合成

Video Signals Sampling and Synthesis Based on STC89C516RD

针对具有二值倾向的图像,提出了以STC89C516RD单片机为核心,利用视频信号行同步脉冲作为中断信号源,通过时序逻辑电路,实现视频信号的快速采集与合成。具有硬件简单、图像处理数据量少等特点,为单片机进入图像识别控制领域提出了一种新的设计思想。

For image with tendency to binary value, the way is introduced on how to realize video signals sampling and synthesis with the use of interruption triggered by row synchronization pulse signal and time series logical circuit at the core of the STC89C516RD. It has simple hardware and less data of image processing features, and opens up a new thought for the single - chip microcomputer into image recognition and control field.
