Aiming at the problem that low visible light and noise will not only reduce visual beauty of images but also cause loss important information, an improved Retinex theory method is put forward to enhance illumination images. More specifically, a analytic model applied before original image refine construct with good parameters. Finally, color recovery factor added readjust distortion caused by contrast enhancement in local region image, so as realize corresponding enhancement. Experiments on some challenging real-world low-light revealed effectiveness our limiting images, shows its better than SSR (Single Scale Retinex) MSR (Multi–scale MSRCR (such Multi– scale Color Restoration) technology.
