Paper Abstract

With the development of ultra-high definition television (UHDTV), an effective gamut mapping algorithm (GMA) from high-definition television (HDTV) to UHDTV is vital. In this paper, we propose a hue-preserved GMA in the CIELCH color space. To balance the restriction between the color difference and the utilization rate of gamut, a mapping method based on barycenter transformation is used. With this algorithm, the color signals for HDTV can be applicable to UHDTV and the image quality can be improved significantly.
