COLOR ENHANCEMENT OF TV PICTURE USING RGB SENSOR

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