Patent ID: 6992683

Claim:
A color conversion apparatus for converting an input color signal to match a color gamut of the input color signal with a color gamut of a target Multi Primary Display (MPD) using at least four primary colors, the apparatus comprising: a WYV color signal conversion unit for converting the input color signal into a WYV color signal for a first output; a color gamut matching gain calculation unit for calculating a matching gain which is a conversion value for matching the color gamut of the input color signal with the color gamut of the target MPD; a color gamut matching unit for converting the WYV color signal based on the matching gain; an XYZ color signal conversion unit for converting the converted WYV color signal into an XYZ color signal for a second output; and an MPD control vector calculation unit for calculating a control vector which is a driving signal of the target MPD corresponding to the XYZ color signal.
