colour.models.ootf_BT2100_PQ(E: ArrayLike) → NDArrayFloat[source]#

Define 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 (ArrayLike) – \(E = {R_S, G_S, B_S; Y_S; or I_S}\) 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:: numpy.ndarray
