Abstract
A color gamut mapping method for multimedia equipment is disclosed. This method performs color gamut mapping on a video signal received by the multimedia equipment and gives an output, wherein the video signal is in a first color gamut while display light of the multimedia equipment is in a second color gamut. The color gamut mapping method for multimedia equipment comprises the steps of: converting the received video signal into a luminance signal and a chrominance signal, and calculating a two-dimensional plane according to the luminance signal and the chrominance signal, wherein the two-dimensional plane intersects the first color gamut to obtain a first region and intersects the second color gamut to obtain a second region; calculating location of a to-be-mapped point corresponding to the video signal in the first region according to the luminance signal and the chrominance signal of the video signal, and calculating a mapping point in the second region by making calculations on the to-be-mapped point to output a mapping point signal.
