colour.CAM02SCD_to_XYZ#
- colour.CAM02SCD_to_XYZ(Jpapbp: ArrayLike, **kwargs: Any) NDArrayFloat [source]#
Convert from Luo et al. (2006) CAM02-SCD colourspace \(J'a'b'\) array to CIE XYZ tristimulus values.
- Parameters:
Jpapbp (ArrayLike) – Luo et al. (2006) CAM02-SCD colourspace \(J'a'b'\) array.
kwargs (Any) – {
colour.CIECAM02_to_XYZ()
}, See the documentation of the previously listed definition. The default viewing conditions are that of IEC 61966-2-1:1999, i.e., sRGB 64 Lux ambient illumination, 80 \(cd/m^2\), adapting field luminance about 20% of a white object in the scene.
- Returns:
CIE XYZ tristimulus values.
- Return type:
Warning
The
XYZ_w
parameter forcolour.XYZ_to_CAM16()
definition must be given in the same domain-range scale than theXYZ
parameter.Notes
SCD in CAM02-SCD stands for Small Colour Differences.
