Abstract

A vision system for a vehicle includes a camera disposed at a vehicle and having a field of view exterior and forward of the vehicle. The camera includes an imager and a lens. The imager captures image data. The camera includes an imager interface disposed on a circuit board that is compatible with one or both of 8-bit MIPI-CSI2 and 12-bit parallel. The imager interface is connected to an image processor that processes image data captured by the imager.

Claims

1. A vision system for a vehicle, said vision system comprising:

a camera disposed at a vehicle and having a field of view exterior and forward of the vehicle;

wherein said camera comprises an imager and a lens;

wherein said imager captures image data;

wherein said camera comprises (i) a circuit board, (ii) an imager interface disposed on said circuit board and (iii) an image processor disposed on said circuit board;

wherein said imager interface is connected on said circuit board between said imager and said image processor of said camera, and wherein said imager interface is compatible with an 8-bit MIPI-CSI2 interface;

wherein said image processor processes image data captured by said imager and received at said image processor via said imager interface; and

wherein an MIPI-CSI2 compatible differential clock is routed to a VSYNC signal and an HSYNC signal.

2. The vision system of claim 1, wherein said imager interface comprises a single imager interface.

3. The vision system of claim 2, wherein said imager is disposed on said circuit board.

4. The vision system of claim 1, wherein said image processor comprises an image processing chip.

5. The vision system of claim 4, wherein said image processing chip is capable of 8-bit MIPI-CSI2.

6. The vision system of claim 1, wherein said camera comprises a forward viewing camera disposed at and viewing through a windshield of the vehicle.

7. The vision system of claim 1, wherein said image processor processes image data captured by said imager for a function selected from the group consisting of (i) traffic sign recognition, (ii) headlamp control, (iii) pedestrian detection, (iv) collision avoidance and (v) lane marker detection.

8. A vision system for a vehicle, said vision system comprising:

a camera disposed at a windshield of a vehicle and having a field of view through the windshield and exterior and forward of the vehicle;

wherein said camera comprises an imager and a lens;

wherein said imager captures image data;

wherein said camera comprises (i) a circuit board, (ii) a single imager interface disposed on said circuit board and (iii) an image processor, and wherein said single imager interface is connected on said circuit board between said imager and said image processor of said camera, and wherein said imager interface is compatible with both an 8-bit MIPI-CSI2 interface and 12-bit parallel interface;

wherein said image processor processes image data captured by said imager and received at said image processor via said imager interface; and

wherein an MIPI-CSI2 compatible differential clock is routed to a VSYNC signal and an HSYNC signal.

9. The vision system of claim 8, wherein said imager is disposed on said circuit board.

10. The vision system of claim 8, wherein said image processor comprises an image processing chip.

11. The vision system of claim 8, wherein at least one parallel signal unused by 8-bit MIPI-CSI2 is routed to ground.

12. The vision system of claim 8, wherein said image processor processes image data captured by said imager for a function selected from the group consisting of (i) traffic sign recognition, (ii) headlamp control, (iii) pedestrian detection, (iv) collision avoidance and (v) lane marker detection.
