还是以《RGB coordinates of the Macbeth ColorChecker (babelcolor.com)》中的Color Checker2005为例,说明各色域之间的转换关系。 首先Lab域和XYZ域之间是可以互相转换的,这里需要注意的是——XYZ域的数值有两种表达方式,分别是将饱和白点的Y设为100(在下面的描述中将以 XYZ100 或者Y100 表述)的方式和将饱和白点的...
The AS73211 is a digital XYZ sensor with I2C interface for relative and absolute color measurement and control. The combination of True Color XYZ sensitized photodiodes with a filter function based on the standard CIE 1931/DIN 5033 (human eye perceptio
This study aimed to develop a transformation matrix for obtaining XYZ color coordinates from the RGB values of digital images for agricultural applications. The calibration procedure was based on Munsell and Macbeth color charts. The color coordinates of eight color charts were measured, and the ...
The LMS color space is defined based on three coordinates L, M and S, each one measuring the strength of excitation of one of the three types of cones in the retina of the human eye. Note that it is physically not possible e.g. to have a non-zero M value combined with L and S ...

In the XYZ color space −The Y component represents the luminance or brightness of the color. The X and Z components determine the chromaticity coordinates or the color's position on the color spectrum. By combining different values of X, Y, and Z, any visible color can be represented ...
Computes the chromaticity coordinates of a specified correlated color temperature (CCT) on the Planckian locus. The specified CCT must be greater than 0. A meaningful CCT range is [1667, 25000]. The transform is computed using the methods in Kang et al.,Design of Advanced Color - Temperature...
The L*, a*, b* coordinates are correlated directly to the standard color values, X, Y, and Z. Source:Zeiss. TheCIE XYZmodel and chromaticity diagram are not perceptually uniform. A more uniform version of CIE was defined in 1976, officially known as CIE L*a*b*. L* stands for lumina...

"XYZ" (Tristimulus Values) encodes the color and the brightness. The values of X, Y, and Z do NOT add up to 1. "xyz" (Chromaticity Coordinates) encode only the color, and no brightness. In this case the values of x, y, and z do add up to 1. ...
