(V, L_B=0, L_W=1)[source]¶ Defines Recommendation ITU-R BT.1886 electro-optical transfer function (EOTF / EOCF).
- Parameters
V (numeric or array_like) – Input video signal level (normalised, black at \(V = 0\), to white at \(V = 1\). For content mastered per Recommendation ITU-R BT.709, 10-bit digital code values \(D\) map into values of \(V\) per the following equation: \(V = (D-64)/876\)
L_B (numeric, optional) – Screen luminance for black.
L_W (numeric, optional) – Screen luminance for white.
- Returns
Screen luminance in \(cd/m^2\).
- Return type
