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. Softcopy 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 psychophysical 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 difference from different media, which can be a tool to evaluate image color difference of softcopy and hardcopy.
