A Better Color Matching between HD and UHD Content
The introduction of a wide-gamut color space in Ultra-HD television creates a need to match colors on wide-gamut UHD displays with colors on conventional HD displays. Many contemporary color conversion methods that apply to conversion from HD to SD, and color conversion methods mandated by current television standards, fail to produce a good color match when converting colors from HD or narrow-gamut UHD color spaces to the wide-gamut UHD color space. This paper illustrates the color errors caused by the application of several of these conversion methods, and recommends one method, using display-referred colorimetry, for better color matching between narrow-gamut and wide-gamut displays.
