<p>The device has a sensor (14) that detects the presence of a person in a detection area (16) and activates a presence detection signal (26). The sensor is connected with an electronic image evaluation unit (24) with an image capture unit. The comparison units (32) compare the sub-picture data with predetermined stored partial image data of storage units (36,52) and generates a first likelihood data and second likelihood data (56). A logic and threshold unit (50) generates logic and threshold detection signal with a predetermined weight ratio of the first and the second likelihood data.</p> |
