This paper proposes a method of color reproduction considering the viewing conditions of PDP TV. 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 brightness and the flare effect. The chromatic adaptation is finally applied to reproduce colors in PDP TV using the information from the viewing conditions by the sensor. Also, in a dark area like a deep night, images by the adaptation results in low-power onsumption. the images reproduced by the proposed method are visually more superior to those reproduced by a conventional method in the experiments.
