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
