Abstract: HDR transfer functions extend the dynamic range of images but will likely operate with displays that have diverse capabilities in luminance and color space. In addition, video assumptions such as system gamma, visible black level, and the 0 to 1.0 video coding domain must be reexamined for high-dynamic range and wide-gamut color. Only part of an HDR signal may contain valid content and it may need to be ‘re-rendered’ for the capabilities of a display including techniques such as tone curve operators, gamut mapping, viewing environment corrections, and other color adjustments. Choice of a color space for manipulation of the signal can have a significant effect on color fidelity, and the use of tone mapping operators and color grading is reviewed. A color signal processing diagram is described to improve interoperability of HDR signals on displays with smaller ranges than the original HDR/WCG signal.
