Gamma Adjustment
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.
1. Enter the menu
Home/Image
, and select Gamma.
