Construction and evaluation of three-dimensional gamut for UHDTV based on the additive color mixing principle

摘要

For UHDTV systems specified by ITU, the paper calculated gamut coverage of UHDTV systems. The paper also constructed a three-dimensional gamut model for UHDTV and computed the color solid volume in the L*a*b* color space. Then it was compared with HDTV systems and Pointer gamut. The result shows that UHDTV gamut completely contains HDTV gamut and Pointer gamut.
