Abstract
A driver assistance system for a vehicle includes an imaging device disposed at least partially within an exterior rearview mirror assembly of the vehicle. With the exterior rearview mirror assembly attached at a side of the vehicle, the imaging device has a field of view forward of the mirror assembly, rearward of the mirror assembly and sideward of the mirror assembly. A control processes image data captured by the imaging device and is operable to determine that the imaging device is misaligned when the imaging device is disposed at least partially within the exterior rearview mirror assembly at the side of the equipped vehicle. The control, responsive to a determination of misalignment of the imaging device, is operable to at least partially compensate for misalignment of the imaging device by at least one of (i) adjusting processing of captured image data and (ii) adjusting the captured image data.

26. A driver assistance system for a vehicle, said driver assistance system comprising:
-
an imaging device comprising an array of photosensing pixels, wherein said imaging device is disposed at least partially within an exterior rearview mirror assembly that attaches at a side of a vehicle equipped with said driver assistance system; wherein said imaging device comprises a CMOS array of photosensing pixels; wherein, with said exterior rearview mirror assembly attached at the side of the equipped vehicle, said imaging device has a field of view forward of said exterior rearview mirror assembly in a direction towards the front of the equipped vehicle and has a field of view rearward of said exterior rearview mirror assembly in a direction towards the rear of the equipped vehicle and has a field of view sideward of said exterior rearview mirror assembly in a direction away from the side of the equipped vehicle at which said exterior rearview mirror assembly is attached; a control for processing image data captured by said imaging device; wherein said control is operable to determine that said imaging device is misaligned when said imaging device is disposed at least partially within the exterior rearview mirror assembly at the side of the equipped vehicle; wherein said control, responsive to a determination of misalignment of said imaging device, is operable to at least partially compensate for misalignment of said imaging device by at least one of (i) adjusting processing of captured image data and (ii) adjusting said captured image data; wherein a portion of the side of the equipped vehicle is present in the field of view of said imaging device and wherein said portion of the equipped vehicle comprises a portion of the side of the equipped vehicle at which said exterior rearview mirror assembly is mounted when attached at the side of the vehicle; wherein the equipped vehicle comprises a left side and a right side, and wherein said imaging device is disposed at least partially within an exterior rearview mirror assembly that attaches at the left side of the equipped vehicle, and wherein when said exterior rearview mirror assembly is attached at the left side of the equipped vehicle, another exterior rearview mirror assembly is attached at the right side of the equipped vehicle and wherein another imaging device is disposed at least partially within the another exterior rearview mirror assembly that is attached at the right side of the equipped vehicle, and wherein a rear backup camera is located at a rear portion of the equipped generally centrally between where said left side-attached imaging device and the right side-attached another imaging device are disposed at the vehicle, and wherein the field of view of said left side-attached imaging device overlaps with the field of view of the rear backup camera and wherein the field of view of the right side-attached another imaging device overlaps with the field of view of the rear backup camera; wherein image data captured by said left side-attached imaging device, by the right side-attached another imaging device and by the rear backup camera is processed by an image processor and, at least in part responsive to said processing by said image processor, a composite image is displayed by a display disposed in the interior cabin of the equipped vehicle positioned within the driver'"'"'s physiological field of view without obstructing the driver'"'"'s view through the windshield of the equipped vehicle; wherein said display comprises a flat panel display; wherein said flat panel display comprises a back-lit liquid crystal display; and wherein said composite image provides a panoramic view that approximates a view from a single virtual image capture device. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34)
