- colour.models.eotf_inverse_BT2100_PQ(F_D: ArrayLike) NDArrayFloat [source]#
Define Recommendation ITU-R BT.2100 Reference PQ inverse electro-optical transfer function (EOTF).
- Parameters:
F_D (ArrayLike) – \(F_D\) is the luminance of a displayed linear component \({R_D, G_D, B_D}\) or \(Y_D\) or \(I_D\), in \(cd/m^2\).
- Returns:
\(E'\) denotes a non-linear colour value \({R', G', B'}\) or \({L', M', S'}\) in PQ space [0, 1].
- Return type:
