Gamma correction

Chapter 118

Gamma correction

Gamma correction is used to alter hardware colormaps to compensate

for the non-linearities in the phosphor brightness of monitors. Gamma

correction can be used to improve the “ropy” or modulated appearance of

antialiased lines. Gamma correction is also used to improve the

appearance of shaded graphics images, as well as scanned photographic

images that have not already been gamma corrected.
