全彩色LED大屏的亮度非线性修正

Correction of Non-linearity of Luminance For Color LED Display

介绍LED显示屏γ修正的基本原理和方法, 给出输出位数高于输入位数的编码查找表(LUT)公式, 并推荐几种实用的修正曲线模型。同时就一些常见的问题进行讨论。

This article discusses the principle of gamma correction and proposes a formula of LUT creation in which output data consist of more bits than input, so can compensate non linear precisely,some inverse gamma correction curves are also recommended, which could do the correction better.
