Dark images are acquired under low light level condition and they have some weakness about image contrast and distortion of color. However, the most studies about dark image tried not to recover colors of the image, but to improve the image contrast. For this reason, we propose the method combined with the tone mapping and MSRCR in order to recovering the original color. We consider the tone mapping to control brightness of the image and the MSRCR to recover the original color. As experimental images, we employed synthesized images, created from the Barnard’s data set. We also consider the Euclidean distance and the angular error between images as the evaluation factors. The performance of the proposed method was evaluated by two experiments. First, we carried out the performance comparison of our method and some well-known color constancy methods. Secondly, we analyzed the performance according to change parameters of MSRCR. The experimental results tell us that the proposed method is more suitable for recovering the color of the dark images than the other methods.
