一、引言定量地评定彩色还原质量,是个极其复杂的问题。长期以来,人们认为被还原的颜色与原景物的颜色在物理测量上愈接近,质量就愈好。但据近二十多年来有关彩色还原质量的心理物理学的研究表明,事情并非这样简单。在彩色摄影、彩色电视以及彩色印刷中,某些被还原的颜色与原景物的颜色有 I. INTRODUCTION Quantitatively assessing the quality of color reproduction is an extremely complex issue. For a long time, people think that the color of the restored object and the color of the original scene closer to the physical measurement, the better the quality. However, according to the research on psychophysics of color reproduction quality for more than two decades, it is not that simple. In color photography, color television and color printing, some of the colors that are restored and the colors of the original scene are
