| 摘 要： | 提出了基于映射表的彩色图像变换思想。在图像处理之前预先建立象素颜色分量在给定变换下的映射值表，再逐一将各象素分解为红、绿、蓝颜色分量，并直接在映射值表中查找得到颜色分量的变换结果，可以大大提高图像处理的速度。

| Abstract: | This paper offers a color-image processing idea based on mapping-table. Before transforming a color-image, we establish a mapping-table for all possible value of color partial-value R, G, B. When each pixel needs to be processed, its color value is divided into three partial values R, G and B, and their transformed results are obtained from the table. This method can improve the processing speed greatly. |
