图像处理中GAMMA校正的研究和实现
A Study on Gamma Correction and Its Implementation in Image Processing
【摘要】 对图像处理中的GAMMA校正进行了详细分析,从CRT(阴极射线管)显示器和人类视觉特性两方面分析了GAMMA校正的必要性,给出了RGB三原色的非线性编码,并对GAMMA校正给出了基于帧缓存颜色查找表的实现方法。
【Abstract】 In this article the Gamma Correction of image processing is discussed in detail. It is essential to apply Gamma Correction to image processing because of the characteristics of CRT display and human vision property.Nonlinear coding of tristimulus(RGB) is given as well as Gamma Correction based on the framebuffer color look-up table.
