Paper Abstract

Gray level reproduction in dark areas is one of the major image quality issues of PDP(Plasma Display Panels) that represents gray levels with pulse count modulation. Error diffusion and dithering have been frequently utilized for smooth tone reproduction in dark areas. However, they may result in side effects such as the visibility of minor pixels, flickers and/or motion artifacts. This paper presents a framework to evaluate the performance of gray level reproduction algorithms for PDPs. Various factors affecting the quality of gray level reproduction in dark areas are introduced. Spatiotemporal luminance variations are proposed to measure the performance of the gray level reproduction. Experimental results indicate that the proposed method faithfully represents the performance of gray level reproduction capability of PDPs.
