Abstract
The brightness and the contrast are optimized in a video image which is used for controlling a manipulator unit. For this purpose, the gain/offset control means of a video camera producing the video image, is controlled using an image control unit in a manner such that the image data of an object can be processed by the image control unit in optimum manner. The manipulator unit may comprise an industrial robot manipulating a workpiece or a tool of a machine tool acting upon a workpiece. The manipulator unit can also be constructed as a target tracking platform for tracking a target which is imaged by the video camera.
