eotf_reverse_BT2100_PQ
(F_D)[source]¶ Defines Recommendation ITU-R BT.2100 Reference PQ reverse electro-optical transfer function (EOTF / EOCF).
Parameters: F_D (numeric or array_like) – \(F_D\) 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: numeric or ndarray Notes
