Color signal display apparatus and method

摘要

A color signal processing apparatus calculates a target color gamut including color signal values of each pixel of an input video, and calculates target primary colors corresponding to the calculated target color gamut. The color signal processing apparatus produces the calculated target primary colors by mixing primary colors in an input color gamut of the input video, and converts and outputs the color signal values of each pixel of the input video to match the calculated target color gamut defined by the calculated target primary colors. Since it is possible to adaptively transform the input color gamut of the input video, the input video that is reproduced has an increased light quantity and an enhanced contrast.
