Rear looking vision system
First Claim
Patent Images
1. A rearview system for a vehicle comprising:
- first and second imaging devices to develop images of an area to the rear of a vehicle, said imaging devices each having a viewing angle which overlaps with the viewing angle of the other of said imaging devices in an overlap area; and
a system to combine the images from said first and second imaging devices together to form a composite image such that the images from said first and second imaging devices are aligned with respect to a reference frame to compensate for movement of said imaging devices so that the overlap area is not duplicated in said composite image and to correct for movement of said imaging devices.

Abstract
A rear looking vision system for a vehicle may produce a composite image from images produced by different imaging devices having different viewing angles of the region behind the vehicle. The composite image may combine the images so as to avoid duplicating objects within the fields of view of more than one imaging device.

7. A method comprising:
-
receiving an image from a first vehicle mounted imaging device having a viewing angle which overlaps the viewing angle of a second vehicle mounted imaging device such that there is duplication between the images received from said first and second vehicle mounted imaging devices; and
combining said images from said first and second devices together to form a composite image of a region to the rear of a vehicle without duplication arising from the overlap between said devices by aligning the images from said first and second devices so that the overlap area is not duplicated in said composite image and the effects of motion of said imaging devices is removed. - View Dependent Claims (8, 9, 10, 11)
