Abstract
A method for controlling the exposure of a stationary mounted video camera is proposed, which makes it possible to attain an optimal exposure even in difficult light circumstances. For this purpose, measuring zones in the image are evaluated and, using the evaluation, a correction factor is calculated which influences the exposure parameters of the camera.
