We propose a method for enhancing images degraded by hazy scattering and attenuation of lights. Images are enhanced in two steps. The first step is restoration of the hue of colors on the basis of the gray world assumption. This hue restored images are next enhanced with magnifying the contrast of the luminance and the saturation of colors while preserving the hue of colors. Performance of the proposed method is verified for some example images of foggy and underwater photographs.
