본 발명은 우적(4)을 인식하기 위한 장치 또는 방법에 관한 것으로서, 하나의 카메라(1)와 하나의 조명원(3)으로 이루어져 있다. 카메라(1)는 창(2)의 뒤에, 특히 차량 내부의 윈드실드 뒤에 배치되어 있으며, 창(2)의 앞에 있는 원거리 구역에 초점을 맞춘다. 창(2)으로 향하는 최소한 하나의 광선(h, n)을 발생시키기 위한 조명원(3)은 최소한 하나의 광선(h, n)을 창(2)으로 향하게 하여 창의 외측 면(2.2)에서 반사된 최소한 하나의 광선(r2, r2')이 카메라(1)에 도달하게 한다. 카메라(1)에 도달한, 최소한 한 광선(r2, r2')의 광량을 카메라(1)가 측정할 수 있다.

    A device and a method for detecting rain on a pane, e.g. of a motor vehicle, use a camera or other light sensor and a lighting source. The camera is disposed behind an inner surface of the pane and focused onto a far range that lies in front of an outer surface of the pane. The lighting source generates a source light beam and directs it onto the inner surface of the pane such that at least one resultant reflected beam (r2; r2′) that is reflected from the outer surface of the pane impinges on the camera. The light quantity of the at least one resultant reflected beam is measured by the camera.
