Abstract

A camera system for use in a vehicle for simultaneously recognizing rain on its windshield and for monitoring the surroundings, includes: a camera having a camera lens and an image sensor, a mirror system having at least one first mirror and at least one second mirror which are situated in such a way that they define a beam path from a monitored area of the windshield to the first mirror, from there to the second mirror, and from there through the camera lens to a first subarea of the image sensor, the distance along the beam path between the at least one second mirror and the camera lens being smaller than the distance along the beam path between the at least one second mirror and the monitored area.

Claims

1-10. -10. (canceled)

11. A camera system positioned in a vehicle for simultaneously recognizing rain on a windshield of the vehicle and for monitoring the surroundings of the vehicle, comprising:

a camera having a camera lens and an image sensor; and

a mirror system having at least one first mirror and at least one second mirror which are situated in such a way to define a beam path from a monitored area of the windshield to the first mirror, from the first mirror to the second mirror, and from the second mirror through the camera lens to a first subarea of the image sensor;

wherein the distance along the beam path between the at least one second mirror and the camera lens is smaller than the distance along the beam path between the at least one second mirror and the monitored area.

12. The camera system as recited in claim 11, wherein the mirror system is configured in such a way that beams transmitted along the beam path between the at least one second mirror and the camera lens are essentially parallel.

13. The camera system as recited in claim 12, wherein at least one of the mirrors has a spherical curvature.

14. The camera system as recited in claim 13, further comprising:

an illumination system configured to selectively illuminate at least a portion of the monitored area of the windshield.

15. The camera system as recited in claim 14, wherein the illumination system is situated on at least one of the two mirrors.

16. The camera system as recited in claim 14, wherein the at least one second mirror is located within a detection area defined by the camera.

17. The camera system as recited in claim 16, wherein the at least one first mirror is located essentially completely outside of the detection area defined by the camera.

18. The camera system as recited in claim 14, wherein the first subarea of the image sensor takes up an area between 5% and 30% of entire sensor area of the image sensor.

19. The camera system as recited in claim 14, wherein the camera lens is configured in such a way that the beam path from the at least one second mirror through the camera lens and the beam path for monitoring the surroundings through the camera lens on the image sensor do not overlap.
