Abstract

Displays are coming on the market that can produce a larger range of colors over EBU and this has led to much research on the topic of how to use the additional color gamut volume provided by the displays. Some research has focused on different methods to map colors from small to large gamuts, whereas this paper focuses on defining the required gamut boundaries for natural content. Two gamuts were created from the results of a psychophysical experiment that asked observers to choose their preferred image in terms of saturation. One gamut corresponded to the median value of their choices and the second gamut corresponded to the 90% value of their choices. The results indicated that even at the 90% value, the resulting gamut was smaller than that of the wide-gamut display for most hues and actually closer to EBU for some hues. These results are display independent, at least when considering modern displays that can reach luminance values above 250cd/m².
