About gamma correction.
Gamma compensation, or gamma correction, is a way of adjusting the signal input to light output
characteristics of a display or projector in order to suit the eye’s sensitivity to different light levels and to
compensate for non-linearities in displays. Without gamma compensation, images may look too dark or too
bright, lack detail or depth. By adjusting the amount of gamma compensation changes, you change only the
perceived brightness levels.
Different types of displays have different gamma factors that need to be corrected in order to look and be
perceived the same. For example, an MS Windows generated image displayed on a CRT monitor will require
a gamma correction value of about 2.5 to avoid color bleaching and burning.
The gamma curve correction formula is based on output level
∝
input level ^ gamma.
