Abstract:
An illumination unit may include at least one luminous means; a detector, which is configured to be used to detect at least one brightness of an image; at least one controller connected to the at least one luminous means and to the detector, wherein the at least one luminous means can be driven in a manner dependent on the at least one brightness of the image with the aid of the controller; a plurality of luminous means whose brightnesses can be set in each case at least one of individually and in clusters with the aid of the controller; and at least one switch which is configured to be used to short-circuit at least one luminous means.
