eotf_ST2084
(N, L_p=10000)[source]¶ Defines SMPTE ST 2084:2014 optimised perceptual electro-optical transfer function (EOTF / EOCF).
This perceptual quantizer (PQ) has been modeled by Dolby Laboratories using Barten (1999) contrast sensitivity function.
Parameters: - N (numeric or array_like) – Color value abbreviated as \(N\), normalized to the range [0, 1], that is directly proportional to the encoded signal representation, and which is not directly proportional to the optical output of a display device.
- L_p (numeric, optional) – Display peak luminance \(cd/m^2\).
Returns: Target optical output \(C\) in \(cd/m^2\) of the ideal reference display.
Return type: numeric or ndarray
