ABSTRACT:
In indication and image reproduction apparatus, the ambient brightness must be taken into account for an optimum reproduction quality. This requires an optical sensor, which is associated with additional technical outlay. The invention relates to a circuit which allows the ambient brightness to be determined by means of a sensor that is already present in the device, for the reception of data or control signals. In particular for apparatus appertaining to consumer electronics.
