Abstract

The color control of reproduced images has been a critical problem in TV system. The viewer can adjust the color control at the receiver for optimal color reproduction, but frequent color adjustment is the most common problem experienced by the viewer. In this paper, we propose an automatic favorite color control system which represents the favorite color to the viewer on demand. The system consists of phase detector to detect the favorite colors at real time from the color burst signal and color signal, comparators to discriminate the types of favorite color. The proposed system reproduces flesh tone, blue color, and green color. In the proposed algorithm, the variation range of phase detector output voltage was minimized for the favorite color saturation changes and also the color signal phase is readjusted from the color burst signal. Thus, the favorite color was easily detected from the other colors without overlapping of correction range and it provides reference color to viewer.
