colour.CAM02SCD_to_XYZ#

colour.CAM02SCD_to_XYZ(Jpapbp: Domain100, **kwargs: Any) Range1[source]#

Convert from Luo et al. (2006) CAM02-SCD colourspace \(J'a'b'\) array to CIE XYZ tristimulus values.

Parameters:
  • Jpapbp (Domain100) – 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 those 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:

numpy.ndarray

Warning

The XYZ_w parameter for colour.XYZ_to_CAM16() definition must be specified in the same domain-range scale as the XYZ parameter.

Notes

  • SCD in CAM02-SCD stands for Small Colour Differences.
