METHOD FOR CONVERTING DATA, DISPLAY DEVICE, COMPUTING DEVICE AND PROGRAM INCORPORATING SAME, AND METHOD FOR OPTIMISING COEFFICIENTS AND DEVICE AND PROGRAM INCORPORATING SAME

摘要

A method for converting image data within a source gamut into modified image data within a destination gamut, is provided including utilizing a processor to operate on input red-green-blue (RGB) data within the source gamut with a multivariate polynomial function to produce modified RGB data within the destination gamut, wherein the polynomial function includes coefficients optimized in accordance with a predefined criteria such that when displayed on a display device having the destination gamut the modified RGB data have a colour appearance representing a perceptually optimised transform of the input RGB data.
