An object color can be seen differently under different ambient illumination, but the human visual system has color constancy with which the object color can be perceived constantly. When TV is watched under a certain outer illumination, the color on the CPT is somewhat distorted due to the emitting spectrum of outer illumination. In this paper, we suggest both intensity decision and illumination decision functions to consider the influence of illumination. Based on these functions, the color enhancement algorithm in a TV using an RGB sensor is also proposed. The TV of the proposed algorithm has better visual quality for the view point of the human visual system and reproduces enhanced color compared to conventional TV
