Gamma Correction


Gamma correction is the modification of distinction or the lighting in-color on a picture that shown on the computer monitor or has been produced out.

Changing the gamma on an image may correct the entire quality of the image. Therefore, “gamma correction” is used to alter the output levels of a monitor.

A gamma value γ < 1 is sometimes called an encoding gamma, and the process of encoding with this compressive power-law nonlinearity is called gamma compression; conversely a gamma value γ > 1 is called a decoding gamma and the application of the expansive power-law nonlinearity is called gamma expansion.
