摘　　要：由于不同的图像输出媒介有着不同特性,评价不同输出媒介的输出图像质量比较困难。以常见的软拷贝输出及硬拷贝输出为研究对象,建立了基于混合色适应转换的图像色差模型,同时设计了相应的心理物理学实验来验证模型计算结果。研究表明,基于混合色适应转换的图像色差模型,在计算不同媒介输出图像色差时表现良好,基本可以作为评价软拷贝输出与硬拷贝输出图像色差的工具。Evaluation of image quality of different media is difficult because of media＇s different characteristic. Soft- copy and hardcopy as research object was taken as research object. An image difference model based on the mixed chromatic adaptation transform was established and a psychophysieal experiment was designed to verify the computation result of the model. The results showed that the proposed model performs well in computation of the image color differ- ence from different media, which can be a tool to evaluate image color difference of softcopy and hardcopy.
