Abstract
Color accuracy plays a vital role in the motion picture and television industry, where it is analyzed all the way from lighting during production, through compression, to television sets in the home. The most common metric used for evaluating color quality is \DeltaE2000. This metric was designed using standard-dynamic-range signals and is based upon the perceptually nonuniform L^\star a^\star b^\star color space. It has not yet been well tested or optimized for high-dynamic-range and wide-color-gamut signals. In this paper, we will present an extension to existing color difference data sets that includes data from high-dynamic-range and wide-color-gamut displays. From these results, we propose an alternative color differencing metric, \DeltaIC _TC_P, which improves the performance and efficiency of objectively evaluating color accuracy.
