Patent abstract
A system which detects droplets on a translucent surface having a camera which, upon activation, acquires an image of a portion of the surface. A radiation source, upon activation, illuminates the portion of the translucent surface while a control circuit selectively activates both the camera and the radiation source. A processor receives a captured image from the camera and, through image processing, generates an output signal representative of the number of droplets on the portion of the translucent surface.
