colour.models.log_decoding_ERIMMRGB#

Apply the ERIMM RGB log decoding inverse opto-electronic transfer function (OETF).

Parameters:

X_p (Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 1]) – Non-linear encoded data \(X'_{ERIMM}\).
bit_depth (int) – Bit-depth used for conversion.
in_int (bool) – Whether to treat the input value as integer code value or floating point equivalent of a code value at a specified bit-depth.
E_min (float) – Minimum exposure limit.
E_clip (float) – Maximum exposure limit.

Returns:

Linear data \(X_{ERIMM}\).

Return type:

numpy.ndarray

Notes

Domain	Scale - Reference	Scale - 1
`X_p`	1	1

Range	Scale - Reference	Scale - 1
`X`	1	1

This definition has an input int switch, thus the domain-range scale information is only specified for the floating point mode.
