Abstract

This paper proposes a method of color reproduction after considering the viewing conditions of PDP displays. Owing to a change of peripheral environments by a temporal and spatial location of observers, the ambient lightings should be considered in the process of color reproduction of displays. A conventional method enhances the contrast and saturation of images by controlling voltage gains in each channel, so that there is a limit to implementing the phenomenon of human adaptation. This method also faces difficulties in reproducing the perceived colors under a variety of viewing conditions. Accordingly, in order to solve this problem, we first characterize the device by considering the average picture level (APL) of PDP displays since the maximum luminance value of a PDP display varies according to the average picture level in order to keep the maximum electric power. In the next step, information about an ambient illuminant is obtained by a sensor and this includes the luminance and correlated color temperature values of ambient lighting. Then, a flare effect is taken into account to exclude the reflected lights in the surface of PDP displays. The chromatic adaptation is finally applied to reproduce colors in PDP displays using the information from the viewing conditions. In the experiments, the images reproduced by the proposed method are visually more similar than those reproduced by a conventional method.
