colour.models.log_decoding_LLog#
- colour.models.log_decoding_LLog(LLog: ArrayLike, bit_depth: int = 10, in_normalised_code_value: bool = True, out_reflection: bool = True, constants: Structure = CONSTANTS_LLOG) NDArrayFloat [source]#
Define the Leica L-Log log decoding curve / electro-optical transfer function.
- Parameters:
LLog (ArrayLike) – L-Log 10-bit equivalent code value \(L-Log\).
bit_depth (int) – Bit-depth used for conversion.
in_normalised_code_value (bool) – Whether the non-linear Leica L-Log data \(L-Log\) is encoded as normalised code values.
out_reflection (bool) – Whether the light level :math`in` to a camera is reflection.
constants (Structure) – Leica L-Log constants.
- Returns:
Linear scene reflection \(LSR\) values.
- Return type:
