colour.models.eotf_SMPTE240M(V_r: Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 1]) → Annotated[ndarray[tuple[Any, ...], dtype[float16 | float32 | float64]], 1]

Apply the SMPTE 240M electro-optical transfer function (EOTF).

Parameters:

V_r (Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 1]) – Video signal level \(V_r\) driving the reference reproducer normalised to the system reference white.

Returns:

Light output \(L_r\) from the reference reproducer normalised to the system reference white.

Return type:

numpy.ndarray
