Uneven illumination in image acquisition process often have a serious impact on image processing.For the deficiency of traditional adaptive Gamma correction in the process of light correction, we present a method of continuous nonlinear Gamma correction.The proposed method has effective compensation for the highlights and shadows at same time, and a faster processing speed than other methods.Experiments show that the method can effectively solve the problem of the non-uniform illumination effects, and improve the quality of the image.
