| | Graphics Lab About gamma correction |
 | | Gamma correction consists of applying the inverse of this relationship to the image before display, i.e. |
 | | For example, if your browser is Netscape Communicator, your image viewer is xv, and the gamma of your display monitor is 2.0, then you can ask xv to apply gamma correction as it displays an image by changing the invoking command in Netscape to "image/*; xv -gamma 2.0 %s". |
 | | This is called the system gamma, and it is intended to compensate for the fact that the images you are viewing typically represent brightly illuminated scenes, but you typically viewing them while seated in a dimly illuminated room, which changes the transfer characteristics of your eye. |
