Abstract

The YCbCr color space in BT.709 suffers the image quality deterioration by color difference signal sub-sampling though reducing the number of signals are quite important issue for future television system. For the future television systems, such as UHDTV and 3DTV, new color encoding space is required which can encode large color gamut and result in good image quality even after color difference signal sub-sampling. In this study, two approaches i.e. following human visual system (CIECAM02) and using new sets of wide color gamut primaries are considered to design new color encoding space. Various YCC color encoding spaces are designed and the sub-sampled image qualities are compared. The result shows that using the opponent color signals in simplified-CIECAM02 as YCC space has the best image quality. Also it is shown that using wide color gamut primaries can improve the sub-sampled image quality significantly than the current encoding color space for HDTV.
