Zusammenfassung:	PURPOSE: A non-linear color gamut compression apparatus and a method using multi-convergent points are respectively provided to make a color of an image displayed on a display apparatus equal to an original image by using a non-linear, multi-convergent type. CONSTITUTION: The non-linear color gamut compression apparatus using multi-convergent point includes a color transforming part(210), a color gamut compression part(220), and a color information reverse transforming part(230). The color transforming part(210) transforms red, green and blue input variables into luminance and chrominance variables. The color gamut compression part(220) non-linearly compresses color information inputted from the color transforming part(210) and performs the luminance-chrominance gamut compression based on a multi-convergent point. And, the color information reverse transforming part(230) converts the compressed luminance and chrominance variables by the color gamut compression part(220) into magenta, yellow and black color coordinates.
