log_decoding_SLog
(y, bit_depth=10, in_legal=True, out_reflection=True)[source]¶ Defines the Sony S-Log log decoding curve / electro-optical transfer function.
Parameters: - y (numeric or array_like) – Non-linear Sony S-Log data \(y\).
- bit_depth (int, optional) – Bit depth used for conversion.
- in_legal (bool, optional) – Whether the non-linear Sony S-Log data \(y\) is encoded in legal range.
- out_reflection (bool, optional) – Whether the light level \(x\) to a camera is reflection.
Returns: Reflection or \(IRE / 100\) input light level \(x\) to a camera.
Return type: numeric or ndarray
