| Abstract: | In this article the Gamma Correction of image processing is discussed in detail. It is essential to apply Gamma Correction to image processing because of the characteristics of CRT display and human vision property.Nonlinear coding of tristimulus(RGB) is given as well as Gamma Correction based on the framebuffer color look-up table. |
