【摘要】 CIE均匀颜色空间及色差公式日益广泛用于彩色复制过程控制和彩色复制品质量评价中,色差的计算对复制的结果起很关键的作用。CIE于2001年推荐了CIEDE2000新的色差公式。利用Munsell颜色系统在视觉上为等色差系统以及色调、彩度和明度可以单独改变的特性,用CIE1976L*a*b*色差公式、CMC色差公式和CIEDE2000色差公式分别计算改变色调、彩度和明度产生的色差,从而检验各色差公式的均匀性。计算结果表明,CIEDE2000色差公式优于CMC色差公式和CIE1976L*a*b*色差公式,对色差计算有了一定的改进。在本实验条件下,取kL=2.6时CIEDE2000色差公式得到的计算结果最好。更多还原

【Abstract】 CIE uniform color spaces and their color difference formulae have been widely used inimaging and reproduction fields to control the imaging process and to evaluate image quality. In 2001,CIE recommend a new color difference formula CIEDE2000. In this experiment, CIE 1976 L*a*b*,CMC and CIEDE2000 color difference formulae are checked and compared making use of thecharacteristic of Munsell color system, which its samples nearby are of equal perceived color differenceand the Munsell hue, chroma and value can be changed independently. The calculation results show thatCIEDE2000 color difference formula is better than both CMC and CIE 1976 L*a*b*. When kL = 2.6,the CIEDE2000 gives the best results in the experiment condition.更多还原
