标准范围

ISO/CIE 11664-5:2016规定了计算CIE 1976 L*u*v*颜色空间坐标的方法，包括亮度、色度、饱和度和色调的相关性。它包括两种方法，用于计算该空间中的欧几里德距离，以表示色差的相对感知大小。它还规定了计算u′、v′均匀色度标度图坐标的方法。ISO/CIE 11664-5:2016适用于使用CIE 1931标准比色系统或CIE 1964标准比色系统的颜色匹配功能计算的三刺激值。ISO/CIE 11664的这一部分可用于说明被视为属于反射或透射物体的颜色刺激，其中需要比三刺激空间更均匀的三维空间。这包括自发光显示器，如阴极射线管，如果它们被用来模拟反射或发射物体，并且刺激物被适当地标准化。ISO/CIE 11664的这一部分作为一个整体，不适用于被视为属于一个区域的颜色刺激，该区域似乎是发射光作为主要光源，或似乎是镜面反射这种光。只有4.1中定义的u′、v′均匀色度标度图以及4.3中定义的色调和饱和度相关性适用于此类颜色刺激。

ISO/CIE 11664-5:2016 specifies the method of calculating the coordinates of the CIE 1976 L*u*v* colour space including correlates of lightness, chroma, saturation and hue. It includes two methods for calculating Euclidean distances in this space to represent the relative perceived magnitude of colour differences. It also specifies the method of calculating the coordinates of the u′,v′ uniform chromaticity scale diagram.

ISO/CIE 11664-5:2016 is applicable to tristimulus values calculated using the colour-matching functions of the CIE 1931 standard colorimetric system or the CIE 1964 standard colorimetric system. This part of ISO/CIE 11664 may be used for the specification of colour stimuli perceived as belonging to a reflecting or transmitting object, where a three-dimensional space more uniform than tristimulus space is required. This includes self-luminous displays, like cathode ray tubes, if they are being used to simulate reflecting or transmitting objects and if the stimuli are appropriately normalized. This part of ISO/CIE 11664, as a whole, does not apply to colour stimuli perceived as belonging to an area that appears to be emitting light as a primary light source or that appears to be specularly reflecting such light. Only the u′,v′ uniform chromaticity scale diagram defined in 4.1 and the correlates of hue and saturation defined in 4.3 apply to such colour stimuli.
