colour.models.eotf_BT2020¶
- colour.models.eotf_BT2020(E_p: FloatingOrArrayLike, is_12_bits_system: bool = False, constants: colour.utilities.data_structures.Structure = CONSTANTS_BT2020) FloatingOrNDArray [source]¶
Define Recommendation ITU-R BT.2020 electro-optical transfer function (EOTF).
- Parameters
E_p (FloatingOrArrayLike) – Non-linear signal \(E'\).
is_12_bits_system (bool) – BT.709 alpha and beta constants are used if system is not 12-bit.
constants (colour.utilities.data_structures.Structure) – Recommendation ITU-R BT.2020 constants.
- Returns
Resulting voltage \(E\).
- Return type
