DEVICE FOR CONVERTING COLOR GAMUT LOCALLY IN HSV COLOR SPACE

摘要

The present invention relates to a local gamut conversion apparatus in an HSV color space capable of changing a specific local color region from a three-dimensional color space to another region in a color gamut-mapped linear HSV color space. To this end, The H, S, and V signals are mapped to predetermined color conversion functions to obtain a color conversion amount, and the obtained color conversion amount is calculated on the input H, S, and V signals to convert the specific color gamut corresponding to the color conversion area And color inversion means for converting the color inverse gamut into a color gamut.;Display, gamut, HSV, local color conversion
