log_decoding_ERIMMRGB
(X_p, bit_depth=8, in_int=False, E_min=0.001, E_clip=316.2)[source]¶ Defines the ERIMM RGB log decoding curve / electro-optical transfer function (EOTF / EOCF).
Parameters: - X_p (numeric or array_like) – Non-linear data \(X'_{ERIMM}\).
- bit_depth (int, optional) – Bit depth used for conversion.
- in_int (bool, optional) – Whether to treat the input value as integer code value or float equivalent of a code value at a given bit depth.
- E_min (numeric, optional) – Minimum exposure limit.
- E_clip (numeric, optional) – Maximum exposure limit.
Returns: Linear data \(X_{ERIMM}\).
Return type: numeric or ndarray
Notes
Domain * Scale - Reference Scale - 1 X_p
[0, 1] [0, 1] Range * Scale - Reference Scale - 1 X
[0, 1] [0, 1] - * This definition has an input integer switch, thus the domain-range scale information is only given for the floating point mode.
