Abstract
Methods are disclosed for adaptive display management using look-up table interpolation. Given a target maximum brightness value for a display, a new look-up table (LUT) for color gamut mapping is determined based on interpolating values from two other pre-computed color gamut LUTs; one computed for a first maximum display brightness larger than the target maximum brightness value, and one computed for a second maximum display brightness lower than the target brightness value. An interpolation scale is computed based at least on the target maximum brightness value and the first maximum display brightness. Methods to reduce the computation load for the translation of RGB data from one color representation (say, ST 2084) to another color representation (say, BT 1866) using fast interpolation methods are also presented.
