摘要:

为了研究跨媒体复现中CIECAM02的背景预测性能,基于双目同时的视觉匹配实验,获得显示器软拷贝与不同中性灰背景下硬拷贝的视觉匹配数据,分析了中性灰背景对颜色外貌的影响,并利用实验数据对CIECAM02的背景预测性能做了评价.实验结果表明:背景明度主要诱导色块明度和彩度的变化,对色相略有影响.明度、彩度、色相三者中,明度改变最明显,背景越暗,诱导色块越亮,随着背景明度变暗,背景明度的诱导绝对量趋于稳定;彩度变化幅度不大,但是不符合色诱导规律;而色相基本不变.CIECAM02可以解释背景明度对明度的诱导现象,但不能解释对彩度的诱导现象,且背景参数不能准确反映背景对颜色的影响,有待于修正.

Abstract:

In order to explore cross-media color reproduction performance on background parameters of CIECAM02, visual color matching experiments based on simultaneous-binocular viewing method are implemented to obtain a set of corresponding color data between monitor and printer.The data was used to analyze background influences on color appearance and test performance of CIECAM02.Results show that background lightness is mainly effective in lightness and chroma.The influence of background lightness is stabilized when its brightness changed from white to black.Chroma changed slightly, but the rule does not meet the color induction.CIECAM02 can explain simultaneous induction of lightness, but not the induction of chroma.And it can't predict the color appearance exactly;its background parameter should be further corrected.

Key words: cross-media, binocular simultaneous matching, visual matching, CIECAM02
