Abstract: 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.
