我的项目中的gamma的变换系数为2.2，是会让图像整体变暗的，看右图说明我的gamma变换模块生效了。

算法

gamma映射是一种简单的、常见的图像处理方法，它能够拓展图像的低亮度区域的灰度级数，让图像的低亮度区域呈现更多的细节，但同时也会让图像的整体亮度变暗，有利有弊。
算法的公式为： y = A*x^g
其中，x为像素点的像素灰度值输入，y为像素点的像素灰度值变换结果，A为归一化系数，g为gamma变换系数。
下图是不同系数的gamma变换曲线。

算法的FPGA部署

首先，gamma变换是个指数函数。用FPGA来运算指数函数相当耗时，所以为了提升速度，我们采用查表法，既将某个gamma变换系数下的0~255灰度等级的所有对应变换结果算出来，然后在需要映射时，直接查表即可。
