Abstract
A sensor system has a video camera and an evaluation unit, the evaluation unit receiving a video signal from the video camera and providing output information relating to luminance and movement of an observation space. The evaluation unit can include a microcontroller that undertakes calculations in order to provide the output information. However, the sensor system can be included in a light control system. A method for controlling an artificial light component of controllable light sources via a light control system includes: picking up a video signal, relaying the video signal to the input of the evaluation unit, evaluating the video signal with reference to luminance and movement in the evaluation unit, outputting the information relating to luminance and movement at the output of the evaluation unit to a control unit and setting a desired brightness of the controllable light sources via the control unit.
