Method and Apparatus for Color Conversion Based on Lch Color Space, and Liquid Crystal Display Device

摘要

The present invention discloses a method and apparatus for color conversion based on LCH color space. The method includes: converting source plane Hn, Hn−1 to target plane Hn′, Hn−1′; computing Hx between Hn and Hn−1; computing Hx′ between Hn′ and Hn−1′ and at the same hue level as t Hx; computing conversion matrix Hn and Hn′; computing target color converted from color of any point of Hx and completing space color of target color. Through this method, it is possible to make the color performance closer to the actual object color or closer to expected effect than the actual object color.
