Patent Images
1. A vision system of a vehicle, said vision system comprising:
- a camera disposed at a vehicle and having a field of view;
wherein said camera comprises an imager and a lens;
wherein said lens comprises a liquid optic;
a control, wherein said control is operable to vary a voltage at said liquid optic to at least one of (i) adjust a tilt of said lens and (ii) adjust a focal length of said lens;
an image processor operable to process image data captured by said camera; and
wherein said control is operable to vary the voltage responsive to one of (i) detection of an object, (ii) movement of an object and (iii) a vehicle input.

Abstract
A vision system of a vehicle includes a camera disposed at a vehicle and having a field of view. The camera includes an imager and a lens, with the lens having a liquid optic. A control is operable to vary a voltage at the liquid optic to adjust the liquid optic to adjust at least one of (i) a tilt of the lens and (ii) a focal length of the lens. The control is operable to adjust the liquid optic responsive to one of (i) detection of an object, (ii) movement of an object and (iii) a vehicle input. An image processor is operable to process image data captured by the camera.

15. A vision system of a vehicle, said vision system comprising:
-
a camera disposed at a side region of a vehicle and having a field of view exterior of the vehicle; wherein said camera comprises an imager and a lens; wherein said lens comprises a liquid optic; a control, wherein said control is operable to vary a voltage at said liquid optic to selectively (i) adjust a tilt of said lens and (ii) adjust a focal length of said lens; an image processor operable to process image data captured by said camera; and wherein said control is operable to vary the voltage responsive to a vehicle input and wherein said vehicle input is indicative of a driving condition of the vehicle. - View Dependent Claims (16, 17, 18)

19. A vision system of a vehicle, said vision system comprising:
-
a camera disposed at a side region of a vehicle and having a field of view exterior of the vehicle; wherein said camera comprises an imager and a lens; wherein said lens comprises a liquid optic; a control, wherein said control is operable to vary a voltage at said liquid optic to adjust a tilt of said lens; wherein said control is operable to vary the voltage responsive to a vehicle input and wherein said vehicle input is indicative of a driving condition of the vehicle; wherein, responsive to said vehicle input being indicative of forward driving of the vehicle along a road, said control is operable to vary the voltage to adjust the tilt of said lens to adjust the field of view of said camera rearward to a blind spot viewing orientation, where a principal axis of the field of view of said camera is generally rearward; wherein, responsive to said vehicle input being indicative of a parking maneuver of the vehicle, said control is operable to vary the voltage to adjust the tilt of said lens to adjust the field of view of said camera downward to a surround view display orientation, where a principal axis of the field of view of said camera is generally sideward and downward; an image processor operable to process image data captured by said camera; and wherein said image processor is operable to process captured image data for a blind spot detection system of the vehicle when said camera is in the blind spot viewing orientation. - View Dependent Claims (20)
