Abstract

Reproduction of more pleasing colors for natural objects is one of the available methods to improve image quality. This paper deals with the saturation enhancement of blue sky to increase the preference of scenery images by introducing the saturation enhancement factor determined by an average saturation of the whole sky region and the weight using the relative pixel position as well as original saturation.
