Core Color Rendering Algorithms for High Dynamic Range Display
As is well known, colors as they exist in the real world must be adjusted so as to look correct and pleasing when displayed on a TV or a cinema screen. In color science, the process of converting these “scene-referred” colors to “display-referred” colors is termed “rendering.” The Academy Color Encoding System (ACES) is a good example of a set of open-source picture rendering algorithms. In this paper, the authors, who both participated in the development of ACES, discuss the pros and cons of various rendering techniques and share the results of their latest work. Specifically, we present a method of applying a tone curve that preserves color ratios and has better noise properties than earlier techniques. This algorithm has been successfully used as part of a larger parametric rendering system for high dynamic range display. One of the nice properties of this algorithm is that it has a simple and robust inverse.
