colour.models.eotf_inverse_PQ_BT2100(F_D: FloatingOrArrayLike) → FloatingOrNDArray

Define Recommendation ITU-R BT.2100 Reference PQ inverse electro-optical transfer function (EOTF).

Parameters

F_D (FloatingOrArrayLike) – \(F_D\) 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

numpy.floating or numpy.ndarray
