The invention relates to a device for detecting rain (4). The device comprises a camera (1) and a lighting source (3, 30) for emitting visible light (h, n) onto a window (2). The camera (1) and the lighting source (3, 30) are embodied and arranged in such a way that the camera can detect a signal of the visible light (r1, r2') which the lighting source emits onto the window (2). In particular, in this context the signal which is detected by the camera (1) correlates with visible light (r1, r2') of the lighting source (3, 30), which visible light is reflected or scattered at the inside (2.1) of the window or outside (2.2) of the window and/or at the raindrop (4). The visible light passes through a shutter device (20) which causes the light to be blocked or highly attenuated in a predefined direction perpendicular to the illumination direction of structures (21) of the shutter device (20). In contrast, the light in the direction perpendicular to the predefined direction and to the illumination direction can propagate virtually unimpeded through the shutter device.
