 Gamma (Gamma Correction)
Gamma is an image quality enhancement function
that offers a richer image by brightening the darker
portions of the image without altering the bright-
ness of the brighter portions.

scenes, such as a film or concert, or when you are
displaying images in a bright room, this feature
makes the dark scenes easier to see and gives the
impression of greater depth in the image.
