LCD Gamma 自动矫正的实现
LCD automatic Gamma correction
LCD Gamma是用曲线表示的，这是一种人眼对光的一种感应曲线。根据惠普提供的研究证明，Gamma2.2是非常接近人类视觉的一个标准。通过对LCD Gamma调试原理以及手动调试方法的研究，设计一种系统来实现LCD Gamma自动矫正过程。该系统包含PC，LCD灰阶信号输入系统，DAC转换系统，光学亮度量测设备CA-210。本系统通过CA-210量测每个灰阶的亮度，并将此数据送给PC，PC通过Gamma2.2的标准，算出该灰阶的标准亮度，通过步进算法算出该点的标准电压。并将此标准电压送至DAC系统控制LCD Gamma电压。从而实现自动测试以及自动调节的功能。
hrough the LCD Gamma debugging principle and manual debugging method of research, design a system to realize automatic straightening process LCD Gamma. This system includes PC, LCD gray scale signal input system, DAC conversion system, optical light measurement equipment CA - 210. This system through the CA - 210 measuring each gray scale brightness, and the data to PC, PC through the Gamma2.2 standards, work out the gray scale standard brightness, through the stepping algorithm calculate it.in standard voltage. And the standard voltage sent to the DAC system control LCD Gamma voltage. So as to realize the automatic test and automatic control function.
