colour.models.log_decoding_CanonLog2¶
- colour.models.log_decoding_CanonLog2(clog2: FloatingOrArrayLike, bit_depth: int = 10, in_normalised_code_value: bool = True, out_reflection: bool = True) FloatingOrNDArray[source]¶
Define the Canon Log 2 log decoding curve / electro-optical transfer function.
- Parameters
clog2 (FloatingOrArrayLike) – Canon Log 2 non-linear data.
bit_depth (int) – Bit depth used for conversion.
in_normalised_code_value (bool) – Whether the Canon Log 2 non-linear data is encoded with normalised code values.
out_reflection (bool) – Whether the light level \(x\) to a camera is reflection.
- Returns
Linear data \(x\).
- Return type
