Abstract

A camera arrangement for a vehicle includes a camera and an electrical conductor structure. The camera is separated from a pane which divides an outside region from an inside region. The camera is in the inside region and is pointed at a portion of the pane such that the camera has a viewing detection region through the pane. The conductor structure forms a device and is on the portion of the pane within the viewing detection region of the camera whereby the camera and the device use the same portion of the pane for their operations.

Claims

1. A camera arrangement comprising:

a camera separated from a pane which divides an outside region from an inside region, wherein the camera is in the inside region and is pointed at a portion of the pane such that the camera has a viewing detection region through the pane; and

an electrical conductor structure which forms a device, wherein the conductor structure is in front of the camera on the portion of the pane within the viewing detection region of the camera such that the camera is pointed at both the portion of the pane and the conductor structure whereby the camera and the device use the same portion of the pane for their operations;

an optical element connected to the pane, wherein the optical element is between the camera and the pane and is in front of the camera;

wherein the conductor structure is on the portion of the pane within the viewing detection region of the camera and is completely within an area covered by the optical element on the pane.

2. The arrangement of claim 1 wherein:

the conductor structure includes transparent regions and non-transparent regions, wherein the camera is able to view through the transparent regions.

3. The arrangement of claim 1 wherein:

the conductor structure includes a transparent support which is on the portion of the pane within the viewing detection region of the camera.

4. The arrangement of claim 3 wherein:

the conductor structure further includes non-transparent printed conductor tracks which are on the transparent support and form the device;

wherein the transparent support and the non-transparent printed conductor tracks enable the conductor structure to have transparent and non-transparent regions, wherein the camera is able to view through the transparent regions.

5. The arrangement of claim 3 wherein:

the transparent support has a refraction index substantially similar to the refraction index of the pane.

6. The arrangement of claim 1 wherein:

the conductor structure is on the side of the portion of the pane facing the inside region.

7. The arrangement of claim 1 wherein:

the optical element is a prism.

8. The arrangement of claim 1 wherein:

the optical element is a light-guiding element.

9. The arrangement of claim 1 wherein:

the optical element includes a tube filled with an optically transparent material.

10. The arrangement of claim 1 wherein:

the camera is focused on a plane lying in the outside region away from the pane.

11. The arrangement of claim 1 wherein:

the device formed by the conductor structure is a moisture sensor.

12. The arrangement of claim 1 wherein:

the device formed by the conductor structure is a heater.

13. The arrangement of claim 1 wherein:

the pane is a vehicle window.

14. The arrangement of claim 13 wherein:

the vehicle window is a windshield.

15. A camera arrangement comprising:

a camera separated from a pane which divides an outside region from an inside region, wherein the camera is in the inside region and is pointed at a portion of the pane such that the camera has a viewing detection region through the pane;

an electrical conductor structure which forms a device, wherein the conductor structure is between the pane and the camera and is in front of the camera on the portion of the pane within the viewing detection region of the camera such that the camera is pointed at both the portion of the pane and the conductor structure whereby the camera and the device use the same portion of the pane for their operations; and

a light-guiding element connected to the pane, wherein the light-guiding element is between the camera and the pane and is in front of the camera;

wherein the conductor structure is connected to the light-guiding element such that the conductor structure is on the portion of the pane within the viewing detection region of the camera and is completely within an area covered by the light-guiding element on the pane.

16. The arrangement of claim 15 wherein:

the pane is one of a vehicle window and a windshield.

17. A camera arrangement comprising:

a camera separated from a pane which divides an outside region from an inside region, wherein the camera is in the inside region and is pointed along an optical axis at a portion of the pane such that the camera has a viewing detection region through the pane;

an electrical conductor structure which forms a device, wherein the conductor structure is between the pane and the camera and is in front of the camera on the portion of the pane along the optical axis of the camera within the viewing detection region of the camera such that the camera is pointed along the optical axis at both the portion of the pane and the conductor whereby the camera and the device use the same portion of the pane for their operations; and

a light-guiding element connected to the pane, wherein the light-guiding element is between the camera and the pane and is in front of the camera;

wherein the conductor structure is connected to the light-guiding element such that the conductor structure is on the portion of the pane along the optical axis of the camera within the viewing detection region of the camera and is completely within an area covered by the light-guiding element on the pane.

18. The arrangement of claim 17 wherein:

the pane is one of a vehicle window and a windshield.
