33、IAGRAM INTRODUCTION The three-dimensional colour space produced by plotting CIE tristimulus values ( X , Y , Z ) in rectangular coordinates is not visually uniform, nor is the ( x , y , Y ) space nor the two-dimensional CIE ( x , y ) chromaticity diagram. Equal distances in these spaces and diagrams

34、 do not represent equally perceptible differences between colour stimuli. For this reason, in 1976, the CIE introduced and recommended two new spaces (known as CIELAB and CIELUV) whose coordinates are non-linear functions of X , Y and Z . The recommendation was put forward in an attempt to unify the

35、 then very diverse practice in uniform colour spaces and associated colour difference formulae (Robertson, 1990; CIE, 2004). Both these more-nearly uniform colour spaces have become well accepted and widely used. Numerical values representing approximately the relative magnitude of colour difference

36、s can be described by simple Euclidean distances in the spaces or by more sophisticated formulae that improve the correlation with the relative perceived size of differences. The purpose of this CIE Standard is to define procedures for calculating the coordinates of the CIE 1976 L*u* v * (CIELUV) co

37、lour space and the Euclidean colour difference values based on these coordinates. The standard also defines a related chromaticity diagram that is a projection of the CIE x , y diagram maintaining straight lines of dominant and complementary wavelengths. The standard does not cover the alternative u

38、niform colour space, CIELAB (CIE, 2007), nor does it cover more sophisticated colour difference formulae based on CIELAB, such as the CMC formula (Clarke et al., 1984), the CIE94 formula (CIE, 1995), the DIN99 formula (DIN, 2001), and the CIEDE2000 formula (CIE, 2001). 1. SCOPE This CIE Standard spe

39、cifies 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 a

40、lso specifies the method of calculating the coordinates of the u,v uniform chromaticity scale diagram. The Standard 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. The Standa

41、rd 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 refl

42、ecting or transmitting objects and if the stimuli are appropriately normalized. The Standard, 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

43、, v chromaticity diagram defined in Section 4.1 and the correlates of hue and saturation defined in Section 4.3 apply to such colour stimuli.2.
