CAMERA WITH LENS FOR VEHICLE VISION SYSTEM
First Claim
1. A camera assembly for a vision system of a vehicle, said camera assembly comprising:
- an imager disposed at a circuit element, said imager comprising a pixelated imaging array having a plurality of photosensing elements;
a lens;
a lens holder comprising a barrel portion that houses said lens;
wherein said lens holder is positioned relative to an image plane of said imager;
wherein said lens holder comprises a flange protruding outward from said barrel portion;
wherein said flange of said lens holder includes a generally flat structure that comprises a planar surface that resides in a structure plane that is normal to an axis of said barrel portion; and
wherein said lens holder is positioned relative to said image plane of said imager such that said structure plane is parallel to said image plane of said imager and such that said planar surface is a predetermined distance from said image plane, thereby positioning said lens at a desired location relative to said image plane of said imager.

Abstract
A camera assembly for a vehicle vision system includes an imager, a lens and a lens holder. The imager is disposed at a circuit element. The lens holder includes a barrel portion that houses the lens. The lens holder is positioned relative to the imager and includes a flange protruding outward from the barrel portion. The flange of the lens holder includes a generally flat structure having a planar surface that resides in a plane that is normal to an axis of the barrel portion. The lens holder is positioned relative to the imager such that the plane is parallel to the image plane and such that the planar flat surface is a predetermined distance from the image plane, thereby positioning the lens at a desired location relative to the imager.

13. A camera assembly for a vision system of a vehicle, said camera assembly comprising:
-
a front housing portion and a rear housing portion; an imager disposed at a circuit element housed in said front and rear housing portions, said imager comprising a pixelated imaging array having a plurality of photosensing elements; a lens; a lens holder comprising a barrel portion that houses said lens; wherein said lens holder is attached at said front housing portion; wherein said lens holder, when attached at said front housing portion, is positioned relative to an image plane of said imager; wherein said lens holder comprises a flange protruding outward from said barrel portion and wherein said flange has an angled surface that is angled relative to a structure plane that is normal to an axis of said barrel portion; wherein said flange of said lens holder includes a generally flat structure that is established at said angled surface and protrudes from said angled surface of said flange, and wherein said generally flat structure comprises a planar surface that resides in the structure plane that is normal to the axis of said barrel portion; wherein a portion of said angled surface is exposed and not encompassed by said generally flat structure; and wherein said lens holder is positioned relative to said image plane of said imager such that said structure plane is parallel to said image plane of said imager and such that said planar surface is a predetermined distance from said image plane, thereby positioning said lens at a desired location relative to said image plane of said imager. - View Dependent Claims (14, 15, 16, 17)

18. A camera assembly for a vision system of a vehicle, said camera assembly comprising:
-
a front housing portion and a rear housing portion; an imager disposed at a circuit element housed in said front and rear housing portions, said imager comprising a pixelated imaging array having a plurality of photosensing elements; a lens; a lens holder comprising a barrel portion that houses said lens; wherein said lens holder is attached at said front housing portion; wherein said lens holder, when attached at said front housing portion, is positioned relative to an image plane of said imager; wherein said lens holder comprises a flange protruding radially outward from said barrel portion and wherein said flange has an angled surface that is angled relative to a structure plane that is normal to an axis of said barrel portion; wherein said flange of said lens holder includes generally flat structures that are established at said angled surface and protrude from said angled surface of said flange, and wherein said generally flat structures comprise at least two spaced apart structures having planar surfaces that reside in the structure plane that is normal to the axis of said barrel portion; and wherein said lens holder is positioned relative to said image plane of said imager such that said structure plane is parallel to said image plane of said imager and such that said planar surface is a predetermined distance from said image plane, thereby positioning said lens at a desired location relative to said image plane of said imager. - View Dependent Claims (19, 20)
