First Claim
Patent Images
1. A process for the detection of a visibility interference phenomenon comprising the following steps:
- emission of a beam of light from a vehicle, said beam of light being emitted into a field of vision of a camera of the vehicle; and
determining the presence and the nature of a visibility interference phenomenon on the basis of at least one image captured by the camera;
wherein the determination of the nature of the visibility interference phenomenon is effected on the basis of a homogeneity of said visibility interference phenomenon on the image.

5. A detection device for a visibility interference phenomenon comprising:
-
a light source emitting a beam of light from a vehicle, with this beam of light being emitted within the field of vision of a camera of the vehicle; and a control unit to determine a presence and a nature of the visibility interference phenomenon on the basis of at least one image captured by the camera; wherein said control unit determines said nature of the visibility interference phenomenon on the basis of the homogeneity of the visibility interference phenomenon on the image. - View Dependent Claims (6)

8. A detection device comprising:
-
at least one camera mounted on a rear of a vehicle; a control coupled to said at least one camera for capturing an image behind the vehicle; said control being adapted to determine the presence of at least one of rain or an obstacle in response to the homogeneity of the visibility interference phenomenon. - View Dependent Claims (9, 10, 11, 13)

12. A process for the detection of a visibility interference phenomenon comprising the following steps:
-
emission of a beam of light from a vehicle, said beam of light being emitted into a field of vision of a camera of the vehicle; and determining the presence and the nature of a visibility interference phenomenon on the basis of at least one image captured by the camera; wherein the determination of the nature of the visibility interference phenomenon is effected on the basis of a homogeneity of said visibility interference phenomenon on the image whenever rear lights on said vehicle are on.
