- colour.models.log_decoding_ERIMMRGB(X_p: ArrayLike, bit_depth: int = 8, in_int: bool = False, E_min: float = 0.001, E_clip: float = 316.2) NDArrayFloat [source]#
Define the ERIMM RGB log decoding curve / electro-optical transfer function (EOTF).
- Parameters:
X_p (ArrayLike) – Non-linear data \(X'_{ERIMM}\).
bit_depth (int) – Bit-depth used for conversion.
in_int (bool) – Whether to treat the input value as int code value or float equivalent of a code value at a given bit-depth.
E_min (float) – Minimum exposure limit.
E_clip (float) – Maximum exposure limit.
- Returns:
Linear data \(X_{ERIMM}\).
- Return type:
