METHOD FOR CONTROLLING AN IMAGE DISPLAY DEVICE TO ALLOW THE SAME PERCEPTION OF COLOURS OVER A LARGE VARIETY OF OBSERVERS

摘要

For each colour, the method comprises the following steps: —converting the first set of colour coordinates (R0, G0, B0)R representing this colour into a first set of visual tristimulus values (X0, Y0, Z0) representing said colour as perceived by a first observer when displayed using a first set of primaries, —converting said first set of visual tristimulus values (X0, Y0, Z0) into a second set of visual tristimulus values (Xi, Yi, Zi) representing the same colour as perceived by a second observer, —converting said second set of visual tristimulus values (Xi, Yi, Zi) into a second set of colour coordinates (Ri, Gi, Bi)C representing said colour as perceived by said second observer when displayed using a second set of primaries.
