基于LCD显示器的色适应变换及模型评价
Chromatic-adaptation transforms based on LCD monitor and the model assessment
摘要
基于应用越来越广泛的显示器-显示器之间的跨媒体颜色复制, 设计了22个色块, 通过一组显示器不同白点下的视觉匹配实验, 获得匹配显示器在4000K、5000K、7500K、9000K时与待匹配显示器在6500K时的对应色数据, 拓宽对应色数据的研究领域, 并用Von Kries, Fairchild和CMCCAT2000三种色适应模型进行数据预测, 通过分析得出, 当适应场色温偏高时, 采用CMCCAT2000模型会有较好的预测效果, 而当适应场色温偏低时, Fairchild模型的预测效果优于其他两种模型。同时, 在显示器间进行高精度色貌预测时, 也为色适应模型的选择提供依据。
Abstract
Based on widely use in cross-media color reproduction between the monitor, the corresponding data field is broadened by getting the corresponding color data of matching monitor under 4000K,5000K,7500K and 9000K to the reference monitor under 6500K through a set of visual matching experiments under different monitor white dots by 22 designed colors. And the corresponding color data is predicted using the three chromatic adaptation models: Von Kries , Fairchild and CMCCAT2000. Finally, by the analysis it is showed that there is a good prediction effect using CMCCAT2000 model when the monitor color temperature is high and using Fairchild model when it is low. Meanwhile, it provides evidence for the selection of the chromatic-adaptation model when the color appearance is predicted for high precision between monitor.
