Abstract
A rearview vision system for a vehicle includes at least one image capture device directed rearwardly with respect to the direction of travel of the vehicle. A display system displays an image synthesized from output of the image captive device. The display system is preferably contiguous with the forward field of view of the vehicle driver at a focal length that is forward of the vehicle passenger compartment. A plurality of image capture devices my be provided and the display system displays a unitary image synthesized from outputs of the image captive devices which approximates a rearward-facing view from a single location, such as forward of the vehicle.
Claims54
A rearview vision system for a vehicle, comprising:
- at least two image capture devices positioned on the vehicle and directed rearwardly with respect to the direction of travel of said vehicle;
- and
- a display system which displays an image synthesized from outputs of said image capture devices and which approximates a rearward-facing substantially seamless panoramic view from a single location substantially without duplicate redundant images of objects.
A rearview vision system for a vehicle, comprising:
- at least three image capture devices mounted to the vehicle and directed rearwardly with respect to the direction of travel of said vehicle, at least two of said image capture devices being side image capture devices respectively mounted on opposite lateral sides of said vehicle and at least one of said image capture devices being a center image capture device mounted between said side image capture devices wherein said side image capture devices and said center image capture device capture objects rearwardly of the vehicle from different angles;
- and
- a display system which displays an image synthesized from outputs of said image capture devices, the displayed image including image portions from each of said image capture devices combined at boundaries;
- wherein the image portion from said center image capture devices includes a portion which is compressed thereby reducing disjointment at said boundaries.
A rearview vision system for a vehicle having a gear actuator, comprising:
- at least two image capture devices positioned on the vehicle and directed rearwardly with respect to the direction of forward travel of said vehicle;
- a display system which displays an image synthesized from outputs of said image capture devices;
- and
- said display system producing a graphic overlay superimposed on said display image visible to the driver informing the driver of what is occurring in the area surrounding the vehicle.
A rearview vision system for a vehicle having a gear actuator, comprising;
- at least two image capture devices positioned on the vehicle and directed rearwardly with respect to the direction of travel of said vehicle;
- a display system which displays an image synthesized from outputs of said image capture devices;
- and
- image enhancement means for enhancing the displayed image including a graphic overlay superimposed on said image wherein said graphic overlay includes indicia of the anticipated path of travel of the vehicle wherein said graphic overlay is disabled when the vehicle's gear actuator is not in reverse gear.
