An Improvement Scheme of Color Data Acquisition for Fast GAMMA Correction

简要介绍液晶设备进行Gamma校正时色彩数据采集模式改进的目的.针对传统的xy Y测量模式的不足,提出在XYZ测量模式下数据采集的改进步骤;从时间角度说明了改进方案的可行性;介绍XYZ模式下数据处理方法,并给出了XYZ向RGB转换的亮度计算公式以及实现代码;试验证明采用XYZ模式符合Gamma软件系统对数据准确性要求,比传统的xy Y模式节约时间约三倍.

This paper briefly introduces the purpose of improvement in color data acquisition mode when liquid crystal device is used to correct Gamma. To address the problem with the inadequacy of color analyzers xyY of traditional measurement mode, it presents the improvement steps for data acquisition under XYZ measurement mode. And the feasibility of the improvement scheme from time perspective was illustrated. Data processing method under XYZ mode was then introduced, and the brightness calculation formulas and the implementation code for transforming XYZ to RGB were presented. The experiments show that XYZ mode meets the requirements for accuracy of Gamma software system, by using only one third time of traditional xyY mode. The improvement scheme calculated by using XYZ mode is feasible.
