摘要：Development of a Hi-Vision display system with a 42-inch-diagonal DC-type PDP is described. The configuration of the signal processing is discussed, and processing methods for the PDP are proposed. Development of signal-processing LSIs and ICs for the driving circuit is also described. A pre-filter is needed for DC PDPs to avoid color aliasing. However, the sharpness of the displayed image is degraded by the filter. This degradation was compensated for by using an optimal-image enhancer. A resolution of 700 lines was thereby obtained. Processing to improve the gray-scale expression of displayed images was investigated. In some cases, an unnatural color was perceived in dark areas of the displayed images. To avoid this artifact, a pre-processing method for error-diffusion processing is proposed. Four signal-processing LSIs and two ICs for the driving circuit were developed. A high-quality 42-inch Hi-Vision PDP receiver, “Nagano Model”, was thereby achieved.
