ColorBalance

代码说明：

  一幅彩色图像数字化后，在显示时颜色经常看起来有些不正常。这是色通道的不同敏感度，增光因子和偏移量造成的，称为三基色不平衡。这个校正过程称为彩色平衡。(After a digital color image in the display color always looks somewhat normal. This is a different color channel sensitivity factor and credit to offset caused by the imbalance as the three primary colors. This correction process is called color balance.)
