Better Color Matching Between HD and UHD Content

Lars Borg

The introduction of a wide-gamut color space in ultrahigh-definition (UHD) television creates a need to match colors on wide-gamut UHD displays with colors on conventional high-definition (HD) displays. Many contemporary color conversion methods that apply to conversion from HD to standard definition (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.
