Patent ID: 6975390

Claim:
An optoelectronic monitoring device for a motor vehicle, the device comprising: a plurality of imaging systems, each imaging system operable for outputting a respective light beam in order to monitor a respective object; a sensor arranged relative to the imaging systems such that the light beams outputted by the imaging systems are incident to the sensor, the sensor outputting a sensor signal indicative of light received by the sensor; a shutter unit having a plurality of shutter fields, the shutter fields being switchable between light-transmitting and light-blocking modes, each shutter field being arranged between a respective imaging system and the sensor; wherein each shutter field allows light from the light beam outputted from the respective imaging system to be received by the sensor when the shutter field is in the light-transmitting mode; wherein each shutter field blocks the light beam outputted from the respective imaging system from being received by the sensor when the shutter field is in the light-blocking mode; and a controller which controls the shutter fields such that only one of the shutter fields is in the light-transmitting mode at any one time, wherein the controller processes the sensor signal in order to determine conditions of the objects being monitored by the imaging systems.
