Foreword
This corresponds to the standard CIE publication CIE15.2004 "colorimetric" and CIE15.2004 non-equivalent degree of consistency,
The main difference is the tristimulus value calculation formula of the color stimulus function representation.
This standard replaces GB/T 3977-1997 "representation of color."
Compared with the standard GB/T 3977-1997 The main changes are as follows.
--- Standard English name of the original standard "Methodsofcolourspecification" to "Specificationofcolors";
--- Increasing the "CIE standard illuminant", "tristimulus values" and "chromaticity coordinates", "color matching functions" and the definition (3.1 to this standard
3.6);
--- Standardization of terminology and text according to CIE15.2004 updated the latest requirements. The GB/T 3977-1997 "Three
Color coordinate, "" color function "," Purple track "," XYZ color system "," X10Y10Z10 color system "," CIE1964 additional criteria
Chroma observers "were changed to" chromaticity coordinates "," color matching function "," purple border "," CIE1931 standard colorimetric system "and
"CIE1964 standard colorimetric system", "CIE1964 standard colorimetric observer";
--- Give CIE1931 standard colorimetric system and CIE1964 standard colorimetric system in 5.2 and 5.4 can be white color coordinates;
--- Content CIE1931 and CIE1964 chromaticity diagram with the corresponding standard colorimetric observer merged into a chapter, modify color CIE1931
Product figure illuminant D65 and the like can be white positional relationship of E;
--- Modify tristimulus value of the expression is given in the general formula 6.1 and 6.2 (3) and (4), by changing the parameters calculated light color, trans
Shoot color and transmission color tristimulus values;
--- With summations replaced by the formula (1) to (6) of the integral calculation.
The standard color by the National Standardization Technical Committee and centralized.
This standard was drafted. China Institute of Metrology, Shenzhen Haichuan Industry Corp..
The main drafters of this standard. Ma Yu, Chen Ping, Lin Yi Ge, He Weiping, Huang Yongheng.
This standard replaces the standards previously issued as follows.
This standard was first published in 1983, in October 1997 the first amendment.
Color representation
1 Scope
This standard specifies the use CIE1931 standard colorimetric system or CIE1964 standard colorimetric system color representation method.
At 1 ° ~ 4 ° field of view, the use of tristimulus values \u200b\u200band chromaticity coordinates CIE1931 standard colorimetric system representing the color; when more than 4 ° field of view,
Tristimulus values \u200b\u200band chromaticity coordinates using CIE1964 standard colorimetric system representing colors.
This standard applies to object colors (including reflection and transmission color) and light colors.

3 Terms and Definitions
GB/T 5698 and established the following terms and definitions apply to this standard.
3.1
CIE defined by the incident on the object of a specific relative spectral power distribution. Including CIE standard illuminant A and the CIE standard
Quasi illuminant D65.
3.2
In the three-color system, and the amount of test color stimuli color stimuli reach three reference color matching required. In CIE1931 standard colorimetric system
In with X, Y, Z represent the tristimulus values; in CIE1964 standard colorimetric system with X10, Y10, Z10 represents tristimulus values.
3.3
Tristimulus values \u200b\u200bwith each of them and the ratio.
In CIE1931 standard colorimetric system by the tristimulus values \u200b\u200bX, Y, Z coordinates to calculate outstanding x, y, z;
In CIE1964 standard colorimetric system by the tristimulus values \u200b\u200bX10, Y10, Z10 calculate outstanding coordinates x0 10, y 10, z 10.
3.4
Matching energy spectrum of each wavelength required reference color stimuli [X], [Y], [Z] (or [X10], [Y10], [Z10]) of a single set of normalized
Color radiation tristimulus values.
CIE1931 standard colorimetric system color matching function () λ, y () λ, z () λ represented by x0;
CIE1964 standard colorimetric system with color matching functions x0 10 () λ, y 10 () λ, z 10 () λ represents.
3.5
The color of the light emitted by the light source.
