colour.models.log_decoding_VLog¶
- colour.models.log_decoding_VLog(V_out: FloatingOrArrayLike, bit_depth: int = 10, in_normalised_code_value: bool = True, out_reflection: bool = True, constants: colour.utilities.data_structures.Structure = CONSTANTS_VLOG) FloatingOrNDArray[source]¶
Define the Panasonic V-Log log decoding curve / electro-optical transfer function.
- Parameters
V_out (FloatingOrArrayLike) – Non-linear data \(V_{out}\).
bit_depth (int) – Bit depth used for conversion.
in_normalised_code_value (bool) – Whether the non-linear Panasonic V-Log data \(V_{out}\) is encoded as normalised code values.
out_reflection (bool) – Whether the light level :math`L_{in}` to a camera is reflection.
constants (colour.utilities.data_structures.Structure) – Panasonic V-Log constants.
- Returns
Linear reflection data :math`L_{in}`.
- Return type
