《GB/T 3977-2008颜色的表示方法》由TC120(全国颜色标准化技术委员会)归口,主管部门为国家标准化管理委员会。
本标准于1983年首次发布,1997年10月第一次修订。本标准代替GB/T3977―1997《颜色的表示方法》。本标准规定了采用CIE1931标准色度系统或CIE1964标准色度系统表示颜色的方法。在1°~4°视场时,采用CIE1931标准色度系统的三刺激值和色品坐标表示颜色;在大于4°视场时,采用CIE1964标准色度系统的三刺激值和色品坐标表示颜色。本标准适用于物体色(包括反射色和透射色)和光源色。 本标准与GB/T3977―1997相比主要变化如下:
―――标准的英文名称由原标准的“Methodsofcolourspecification”改为“Specificationofcolors”;
―――增加了“CIE 标准照明体”、“三刺激值”和“色品坐标”、“色匹配函数”等定义(本标准的3.1~3.6);
―――全文名词术语规范化并根据CIE15:2004的最新规定进行更新。将GB/T3977―1997中“三色坐标”、“色度函数”、“紫轨迹”、“�����谏�度系统”、“�兀保��伲保��冢保吧�度系统”、“CIE1964补充标准色度观察者”分别修改为“色品坐标”、“色匹配函数”、“紫红边界”、“CIE1931标准色度系统”和“CIE1964标准色度系统”、“CIE1964标准色度观察者”;
―――在5.2和5.4中给出CIE1931标准色度系统和CIE1964标准色度系统等能白光色品坐标;
―――将CIE1931和CIE1964色品图与相应的标准色度观察者的内容合并成一章,修改CIE1931色品图中照明体D65与等能白光E 的位置关系;
―――修改三刺激值表达式,在6.1和6.2中给出通用公式(3)和(4),通过改变参量计算光源色、反
射色和透射色的三刺激值;
―――用求和计算代替式(1)~式(6)的积分计算。
Scope
This standard specifies the method of expressing color by using the CIE1931 standard chromaticity system or the CIE1964 standard chromaticity system. When the field of view is 1°~4°, the color is represented by the tristimulus value and chromaticity coordinates of the CIE1931 standard chromaticity system; when the field of view is greater than 4°, the tristimulus value and chromaticity coordinates of the CIE1964 standard chromaticity system are used to represent the color color. This standard applies to object color (including reflection color and transmission color) and light source color.
