Abstract: To ensure consistent presentation of future wide-gamut digital cinema packages (DCPs) on standard gamut screens, a mandatory gamut mapping strategy has to be chosen. In this paper, current gamut mapping algorithms are evaluated with respect to their application in digital cinema. These algorithms include: “Simple Clip,” “Cusp Clip,” “Minimum delta E” (mindE), “Hue-preserving mindE,” “Weighted mindE,” and the mapping strategy that is used in current projectors. The gamut mapping algorithms under investigation will be provided as three-dimensional (3D) lookup tables for comparison. These can also be used to retrofit a more advanced gamut mapping strategy to standard gamut projectors. Therefore, the paper concludes with an analysis of the losses introduced by using 3D lookup tables for gamut mapping. The intent of this paper is to initiate a discussion about gamut mapping strategies for digital cinema, which may ultimately lead to an addendum to the SMPTE standards for digital cinema.
