colour.models.ootf_BT2100_PQ(E)[source]¶

Defines Recommendation ITU-R BT.2100 Reference PQ opto-optical transfer function (OOTF / OOCF).

The OOTF maps relative scene linear light to display linear light.

Parameters:	E (numeric or array_like) – \(E = {R_S, G_S, B_S; Y_S; or I_S}\) is the signal determined by scene light and scaled by camera exposure.
Returns:	\(F_D\) is the luminance of a displayed linear component (\(R_D\), \(G_D\), \(B_D\); \(Y_D\); or \(I_D\)).
Return type:	numeric or ndarray
