Although with the advent of LEDs energy consumption in buildings can be reduced by 50%, there exists a potential for savings due to lighting controls. Moreover, controls ensure that near zero requirements EU achieved (nZEBs). For this reason, more sophisticated must proposed order take full advantage and their flexibility concerning dimming. This paper proposes architecture an embedded computer camera controller monitoring management image data, which is applied various control cases, particularly digitally controlled devices. The system deals real-time GigE input. An in-house developed algorithm using MATLAB enables identification areas luminance values. microcontroller part complete imaging sensor measure illumination several working room. power was measured compared typical photosensor. functional performance operation evaluated based upon BeagleBone Black board.
