Title (EN) LCH COLOR SPACE-BASED METHOD AND DEVICE FOR COLOR CONVERSION AND LIQUID CRYSTAL DISPLAY DEVICE
(FR) PROCÉDÉ ET DISPOSITIF DE CONVERSION DE COULEUR FAISANT APPEL À L'ESPACE COLORIMÉTRIQUE LCH, ET DISPOSITIF D'AFFICHAGE À CRISTAUX LIQUIDES
(ZH) 一种基于LCH色空间的色彩转换的方法、装置以及液晶显示装置
Abstract:
(EN) An LCH color space-based method and device for color conversion. The method comprises: converting from original planes Hn and Hn-1 to target planes Hn' and Hn-1', calculating an Hx between Hn and Hn-1, calculating an Hx' between Hn' and Hn-1' and identical in hue with Hx, calculating a conversion matrix between Hx and Hx', calculating a post-color-conversion adjusted target color for the color of any one point on plane Hx, and completing the space color of the target color. The method allows for color rendering of increased resemblance to the color of an actual object or for increased resemblance to a preset effect than rendering of the color of the actual object.
(FR) L'invention porte sur un procédé et un dispositif de conversion de couleur faisant appel à l'espace colorimétrique LCH. Le procédé consiste à : effectuer une conversion de plans initiaux Hn et Hn-1 en plans cibles Hn' et Hn-1', calculer un Hx entre Hn et Hn-1, calculer un Hx' entre Hn' et Hn-1' et de teinte identique à Hx, calculer une matrice de conversion entre Hx et Hx', calculer une couleur cible ajustée post-conversion de couleur pour la couleur de n'importe quel point sur le plan Hx, et compléter la couleur d'espace de la couleur cible. Le procédé permet un rendu de couleur ayant une meilleure ressemblance à la couleur d'un objet réel ou une meilleure ressemblance à un effet préréglé qu'un rendu de la couleur de l'objet réel.
(ZH) 一种基于LCH色空间的色彩转换方法和装置,所述方法包括由原始平面Hn以及Hn-1转换为目标平面Hn'以及Hn-1',计算出Hn与Hn-1之间的Ηx,计算出Hn'与Hn-1'之间的与Ηx在同一色相下的Ηx',计算出Ηx与Ηx'之间的转换矩阵,将Ηx平面上任一点颜色计算出色彩转换调整后的目标颜色,并完成目标颜色的空间色彩。该方法能够使色彩表现更接近真实物体颜色或者比真实物体颜色表现更接近预设效果。
