Color Correction Method Using Luminance and Chromaticity of Seven Colors in PDP-TV

Abstract

The displayed colors on PDP-TV screen are not exactly the same as the colors of the transmitted signal from broadcast HDTV because of color reproduction characteristics in PDP-TV. An efficient color correction method is proposed for displaying the digital HDTV-based video signal in PDP-TV by minimizing color reproduction error. It is composed of three correction matrices calculated by using luminance and chromaticity of seven colors. Experimental results show that the average color difference is reduced from 0.0299 to 0.0042 by using the proposed method. The average difference of the proposed method is 0.0021 lower in (u′, v′) chromaticities than that of the conventional method.
