SYSTEMS AND METHODS FOR DETECTING OBSTRUCTIONS IN A CAMERA FIELD OF VIEW
First Claim
1. A system mounted on a vehicle for classifying at least one obstruction on a surface of a window of the vehicle, the system comprising:
- (a) a secondary camera mounted inside the vehicle, said secondary camera focusing on at least a portion of the surface of the window; and
(b) a processor which processes a plurality of secondary images acquired by said secondary camera, and identifies the at least one obstruction when present on the surface;
wherein the surface of the window can be selectably either the external surface of the window or the internal surface of the window.

Abstract
A system mounted on a vehicle for detecting an obstruction on a surface of a window of the vehicle, a primary camera is mounted inside the vehicle behind the window. The primary camera is configured to acquire images of the environment through the window. A secondary camera is focused on an external surface of the window, and operates to image the obstruction. A portion of the window, i.e. window region is subtended respectively by the field of view of the primary camera and the field of view of the secondary camera. A processor processes respective sequences of image data from both the primary camera and the secondary camera.
