- colour.models.oetf_inverse_BT2100_PQ(E_p: ArrayLike) NDArrayFloat [source]#
Define Recommendation ITU-R BT.2100 Reference PQ inverse opto-electrical transfer function (OETF).
- Parameters:
E_p (ArrayLike) – \(E'\) is the resulting non-linear signal (\(R'\), \(G'\), \(B'\)).
- Returns:
\(E = {R_S, G_S, B_S; Y_S; or I_S}\) is the signal determined by scene light and scaled by camera exposure.
- Return type:
