摘要
The method comprises the steps of: —determining, for each color of the second version, corresponding scalar value(s) of one or two variable(s) such that, if said scalar value(s) is applied to the color gamut mapping model, a mapped color is obtained having a minimal distance to the corresponding color of the first version (i.e. enhanced) to the color of second version, —encoding the determined scalar value(s) into an enhancement layer.
