Abstract
A motor vehicle optoelectronic monitoring device includes a sensor, imaging systems, a shutter, and a controller. Each sensor element outputs a sensor element signal based on the intensity of a light signal received by the sensor element. Each imaging system is associated with a sensor region and illuminates an object to monitor the object. Two sensor regions associated with two respective imaging systems partially overlap one another. Each imaging system illuminates the sensor elements of the associated sensor region with a light signal indicative of the object being monitored. The controller controls the shutter unit to selectively enable and disable illumination of the sensor by the imaging systems. The controller processes the sensor element electric signals output by the sensor elements in response to illumination by an imaging system to determine conditions of the object being monitored by the imaging system.
