摘要: 本文描述了一种视频数字图象信号的快速获取方法及在微机系统中的实现.用这种方 法可将缓冲存储器和微机部分内存交换,并可同时取样和装配图象.Abstract: A method for fast video digital image capturing and its implementation in a microcomputer system is described in this paper. By this method, the content of buffer and part of the momory can be exchanged, and sampling and image assembly can be carried out at the same time. So the image can be captured in higher speed. A 256 * 256 image with 64 gray levels can be captured in 0.64 second. This microcomputer-based image capturing system has been used in a mini-microcomputer vision system as an image input unit.
