colour.models.oetf_ST2084(C, L_p=10000)[source]

Defines SMPTE ST 2084:2014 optimised perceptual opto-electronic transfer function (OETF / OECF).

Parameters:
  • C (numeric or array_like) – Target optical output \(C\) in \(cd/m^2\) of the ideal reference display.
  • L_p (numeric, optional) – Display peak luminance \(cd/m^2\).
Returns:

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.

Return type:

numeric or ndarray
