摘要
详细分析了电视图像从摄像、传输到显像整个电视系统中由于摄像机、传输系统和显像管的非线性产生的伽玛失真问题,并提出了伽玛校正的一般摸拟方法,结合现代电视技术分析了AI图像智能电路中的数字化伽玛校正方法.值得同行参考.
The nonlinear GAMMA distortion of TV images in the TV system,which is affected by the camara, transmission, or picture tube,is discussed in the paper;the general analogue method of checking is given;the nu meralization ways of checking and modification in AI image intelligence circuits are analzed by means or modern TV techniques..
