%X The problem of color constancy is one of the important research directions in computer vision, aiming at recognizing the color of the target without the influence of the illumination variances in the scene. Many color constancy algorithms have been proposed in recent years. Most of them use the traditional Von Kries diagonal transformation matrix, which has bad effects to the color images taken under low luminance and high luminance.The Luminance-compensation based transformation matrix proposed in this article is based on the image formation model and optics theory. This new method compensates the image intensity according to the luminance variant of the image pixel. Results of the experiment demonstrate that the proposed method can achieve a good correction for lightness, contrast and color fidelity.
