Abstract
A method for color mapping a video signal into a mapped video signal responsive to at least one color mapping function is disclosed. To this aim, at least one black point offset is determined responsive to a color encoding system of the video signal and to a color encoding system of the mapped video signal. The at least one black point offset and the at least one color mapping function are then applied on the video signal to obtain the mapped video signal.
