VEHICLE VISION SYSTEM WITH MICRO LENS ARRAY
First Claim
1. A vehicular vision system, said vehicular vision system comprising:
- a camera disposed at a vehicle and having a field of view, wherein said camera is operable to capture image data, and wherein said camera comprises an imager having a pixelated array of photosensing elements; and
wherein said camera comprises a lens array disposed at said pixelated array of photosensing elements, wherein said lens array comprises an array of lens elements for imaging light onto respective sub-arrays of photosensing elements of said pixelated array of photosensing elements;
an image processor operable to process captured image data; and
wherein, responsive at least in part to image processing of captured image data captured by photosensing elements associated with different lens elements of said lens array, said vehicular vision system is operable to determine distance to an object present in the field of view of said camera.

Abstract
A vehicular vision system includes a camera disposed at a vehicle and having a field of view. The camera is operable to capture image data. The camera includes a pixelated array of photosensing elements. A lens array may be disposed at the pixelated array of photosensing elements. The lens array includes an array of lens elements for imaging light onto respective sub-arrays of photosensing elements of the pixelated array of photosensing elements. An image processor is operable to process captured image data and, responsive at least in part to image processing of captured image data, the vehicular vision system is operable to determine distance to an object present in the field of view of the camera.

14. A vehicular vision system, said vehicular vision system comprising:
-
a plurality of cameras disposed at a vehicle and having respective fields of view, wherein said cameras are operable to capture image data, and wherein said cameras each comprise an imager having a pixelated array of photosensing elements; and an image processor operable to process captured image data; wherein said plurality of cameras form a Stanford light field array; wherein, responsive to image processing of captured image data, said image processor acquires depth information of a scene in view of said Stanford light field array; wherein said image processor processes a depth map of a scene in view of said Stanford light field array out of the scene'"'"'s depth information; and wherein said depth map comprises an input to a driver assistant system of the vehicle. - View Dependent Claims (15, 16, 17)

18. A vehicular vision system, said vehicular vision system comprising:
-
a camera disposed at a vehicle and having an exterior field of view, wherein said camera is operable to capture image data, and wherein said camera comprises an imager having a pixelated array of photosensing elements; and wherein said camera comprises a lens array disposed at said pixelated array of photosensing elements, wherein said lens array comprises an array of lens elements for imaging light onto respective sub-arrays of photosensing elements of said pixelated array of photosensing elements; an image processor operable to process captured image data; wherein, responsive at least in part to image processing of captured image data captured by photosensing elements associated with different lens elements of said lens array, said vehicular vision system is operable to determine distance to an object present in the exterior field of view of said camera; wherein a virtual view point of said camera is adjustable, and wherein said image processor, responsive at least in part to image processing of captured image data, is operable to determine distance to the object present in the exterior field of view of said camera by comparing image data captured at different virtual view points. - View Dependent Claims (19, 20)
