colour.models.oetf_inverse_PQ_BT2100¶
- colour.models.oetf_inverse_PQ_BT2100(E_p: FloatingOrArrayLike) FloatingOrNDArray [source]¶
Define Recommendation ITU-R BT.2100 Reference PQ inverse opto-electrical transfer function (OETF).
- Parameters
E_p (FloatingOrArrayLike) – \(E'\) 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.
