Method and system for display color calibration

Abstract:

First color response values of vertices of a first unit cube defined within a cubic color output space of the display device are measured. For each of first intermediate values determined based on the measured first color response values, RGB adjustment values are calculated by tetrahedral decomposition and interpolation so that each calculated RGB adjustment value is within a boundary defined by the first unit cube. When boundary defined by the first unit cube is reached, a second unit cube is defined within the cubic color output space, wherein a first vertex of a plurality of vertices of the second unit cube corresponds to the calculated RGB adjustment values of a previous intermediate value that is one of the first intermediate values. Second color response values corresponding to the plurality of vertices of the second unit cube except the first vertex are measured.
