This study tried to extend applicability of colour imaging technologies, e.g. gamut mapping, gamut extension, image quality, to enhance image quality of Plasma Display Panel (PDP) television in terms of recovering mismatches between television standard broadcasting signal and display system. To do this aim a user-friendly interactive tool with four different functions was developed for television ASIC designers. Colour–matching and pleasantness performance of newly derived method using the developer tool was evaluated by psychophysical experiment and traditional quality control process. Six different test images including two moving video clips were used in the experiment.
