Abstract:
1. An image color compensation method, comprising: performing a color space conversion operation, by a way of a color space conversion unit, on a pixel of a source image to convert a plurality of first image signals of the pixel to a plurality of second image signals corresponding to a color space plane, wherein the color space plane comprises a color compensation region; performing a plurality of mathematical and logical operations, by way of an image color compensation unit coupled to the color space conversion unit, on the second image signals to determine a location of the pixel in the color space plane; performing a compensation operation, by way of the image color compensation unit, on the second image signals to make the pixel approach a predetermined direction in the color space plane so as to adjust the color of the pixel when the pixel resides in the color compensation region; wherein the image color compensation unit determines whether the pixel residing in the color compensation region is over compensated, and adjusts a pixel value of the pixel when the pixel is over compensated and obtains a final image, otherwise, the image color compensation unit outputs the pixel directly to generate the final image.
