Abstract

A method of mapping an input image in an input color space into an output image in an output color space, the input color space being larger than the output color space, the method comprising:obtaining (220) an intermediate color space, the input color space being larger than the intermediate color space, the intermediate color space being larger than the output color space;obtaining (221) a dynamic color space conversion operator from an analysis of the input image;applying (222) a first mapping to the input image to obtain an intermediate image in the intermediate color space using the dynamic color space conversion operator; and,applying (223) a second mapping to the intermediate image to obtain the output image applying a static color space conversion operator.
