Gamma correction
text:
Gamma correction or gamma is a nonlinear operation used to encode and decode luminance or tristimulus values in video or still image systems. Gamma correction is, in the simplest cases, defined by the following power-law expression:
- V out = A V in γ, where the non-negative real input value V in is raised to the power γ and multiplied by the constant A to get the output value V out. In the common case of A = 1, inputs and outputs are typically in the range 0–1. A gamma value γ < 1 is sometime
