colour.models.log_encoding_CanonLog2#
- colour.models.log_encoding_CanonLog2(x: ArrayLike, bit_depth: int = 10, out_normalised_code_value: bool = True, in_reflection: bool = True, method: Literal['v1', 'v1.2'] | str = 'v1.2') NDArrayFloat [source]#
Define the Canon Log 2 log encoding curve / opto-electronic transfer function.
- Parameters:
x (ArrayLike) – Linear data \(x\).
bit_depth (int) – Bit-depth used for conversion.
out_normalised_code_value (bool) – Whether the Canon Log 2 non-linear data is encoded as normalised code values.
in_reflection (bool) – Whether the light level \(x\) to a camera is reflection.
method (Literal['v1', 'v1.2'] | str) – Computation method.
- Returns:
Canon Log 2 non-linear data.
- Return type:
