<p>The sensor (C) is associated with an objective (O) having a zone that is focused to infinity and another zone focused in a near field. The objective has a set of optical elements e.g. lens, where the optical elements are provided in or close to an opening pupil plane of the objective. The sensor and the objective are arranged behind the wiped area of the windscreen of a motor vehicle. Rays (r1-r3) entering the objective in order to reach the receiving surface of the sensor are traced. The optical elements are adapted to be focused on the zones. Independent claims are also included for the following: (1) a method of detecting drops of rain on a windscreen (2) an image capturing system for use in a vehicle.</p> |
