摘要
介绍了一种新颖和通用的视频图像采集系统设计方法,本系统主要由专用视频解码芯片SAA7111、可编程逻辑器件CPLD以及DSP等组成。讨论了CPLD逻辑控制系统设计以及DSP处理系统中的关键技术问题。电路设计简单,便于修改采集控制程序,调试方便。
Aiming at the static image transmission, a novel and general method ot video image acquisition is described based on DSP and CPLD in this paper. This idea is favorable for the design of the circuits and easy for debugging. The experimental result indicates that the image transmitted is very clear. Therefore, the system will be extensively applied to some situations such as accidental occasion, fire alarming.
