Abstract
A process for balancing a video signal is set forth. In order to be able to utilize, with particular advantage in the medical field, processes that have been known for a long time, the video signal is balanced in a manner such that the color effect of an image, displayed by a monitor, of a white surface that is illuminated with a selected light source corresponds as closely as possible to the color effect of the original white surface that results from direct observation by the human eye.
