eotf_PQ_BT2100
(E_p)[source]¶ Defines Recommendation ITU-R BT.2100 Reference PQ electro-optical transfer function (EOTF / EOCF).
The EOTF maps the non-linear PQ signal into display light.
- Parameters
E_p (numeric or array_like) – \(E'\) denotes a non-linear colour value \({R', G', B'}\) or \({L', M', S'}\) in PQ space [0, 1].
- Returns
\(F_D\) is the luminance of a displayed linear component \({R_D, G_D, B_D}\) or \(Y_D\) or \(I_D\), in \(cd/m^2\).
- Return type
numeric or ndarray
