This paper proposes a method to improve the contrast of a color image using a genetic algorithm. The accumulated edge strength in the R, G and B channel images that compose an output color image is used for evaluating an individual fitness. The difference of color hues between the original color image and the output color image is also used for evaluating the fitness. The genetic algorithm works to generate an output color image that has large edge strength in the R, G and B channel images and has less difference of the accumulated hues between the original image and the output image. The experimental results show that the output color image by the proposed method had good contrast visually compared with the results by the liner brightness transform method.
