摘　　要： 基于DVI-DVI处理器的亮度逐点校正算法有两种,即算法1和算法2。针对采用两种算法后在亮度偏差量以及数字电路设计方面的差异性进行分析。首先,通过色度学空间转换理论获得校正算法1和校正算法2的模型;然后,分别对采用两种算法引起的亮度偏差量进行对比,通过计算得到算法2和算法1的亮度偏差量比例系数kr;最后,对实现两种算法数字电路应用的资源进行对比。通过两种算法在这两方面的对比得出:算法2更适合应用于DVI-DVI处理器。 Based on DVI-DVI processorthere were two kinds of brightness correction algorithm,algorithm 1 and algorithm 2. The differences between the two algorithms in brightness deviation and digital circuit design have beenanalyzed in detail. Firstly, the expression of calibration algorithm 1 and calibration algorithm 2 has been obtained by the theory of color space transformation; Andthen, the brightness deviation caused by the two algorithms have been compared,and the ratio of luminance deviation of algorithm 2 and algorithm 1 has been calculated;Finally, the two algorithms for digital circuit applications were compared. By comparing the two algorithms in these two aspects：algorithm 2 is more suitable for DVI-DVI processor.
