System and method for generating RGB primary for wide gamut, and color encoding system using RGB primary

摘要

A red, green, and blue (RGB) primary generation system and method for a wide color gamut, and a color encoding system using the RGB primaries. The RGB primary generation system may achieve a wide color gamut by generating a color gamut having a gamut coverage which meets a gamut coverage threshold, meeting a unique hue, having a maximum gamut efficiency, and a minimum quantization error.

主权项

1. A red, green, and blue (RGB) primary generation system, comprising:
an RGB primary setting unit to set RGB primaries; a gamut boundary setting unit to set a gamut boundary of a reference gamut using a data set in a color space; a gamut coverage determining unit to determine whether a gamut coverage of a target gamut meets a gamut coverage threshold, using the reference gamut and the target gamut, based on the set RGB primaries; and a gamut efficiency determining unit to determine whether a gamut efficiency of the target gamut is at a maximum, using the target gamut and the reference gamut, when the gamut coverage meets the gamut coverage threshold.
