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.
