摘　　要：如何通过颜色校正获得真实的颜色重现已成为图像处理中普遍存在的技术难点。针对此类问题,提出一种基于白色模板的颜色校正方法:首先将颜色空间的精度扩展到一定的程度,然后制作一个标准状态下的白色模板;接着根据条件选取适当的校正算子,根据校正算子得出的RGB值去校正在同样条件下得到的目标图像。工程实践和仿真结果表明,校正后的图像不但在视觉上与标准图像达到一致,并且在数值误差上也小于传统的校正方法。A general technique problem in image processing is how to obtain the real chromatic rendition by color correction.In this paper a color correction method based on standard white board was proposed.Firstly the color space must be extended to certain accuracy so that a standard white board could be made.Then according to a such requirement an appropriate corrector was chosen to calculate the value of RGB to correct the target image which was obtained under the same conditions with the corrector.Engineering and simulation analysis indicate that corrected image not only is consistent with the standard image in the visual but also its numerical deviation is smaller than the result of traditional methods.
