CCD相机图像自动稳光技术的研究

The Study on Automatic Light-adjust System of CCD Camera Image

从CCD相机控制时序入手,探讨了两种快门时间的控制方法。整个系统由CCD相机、主控单元、同步信号产生单元、信号调理电路和监视器组成。主控单元采用嵌入式单元AVR系列的Mega16单片机,通过软件设定阈值,实现调光的闭环控制,为调光系统的设计提供了一种新的思路。

The paper begins with the controlling time sequence of CCD camera and distresses two controlling methods of shutter time. The whole system were composed of CCD camera, main controlling unit, synchronization signal generating unit, signal disposing unit and monitor. Mega16SCM of AVR series was adopted as the main controlling Hit while the threshold is setup by software to achieve close -loop control of shutter time, so as to give a new method to the design of light - adjusting systems.
