Abstract

A vehicle image acquisition and display assembly 10 which is deployed within conventional vehicle rear-view mirror housing or shroud members 20, 22 and which selectively provides images of areas/regions and/or objects residing within the front and/or along the side of a vehicle 12.

Claims

1. A mirror assembly for use with a vehicle having an operator, said mirror assembly comprising:

a generally hollow housing having a first open end portion and a second end portion;

a first mirror which is movably disposed within said housing, which substantially covers said first open end portion, which is constrained to only move within said housing, and which provides a first image;

at least a second mirror which is disposed within said housing;

a first member which is disposed within said housing and which is disposed co-planar to and alongside said first mirror, thereby causing said first mirror and said first member to face said operator; and

a second member which is fixedly disposed within said second end portion, which communicates with said at least second mirror and which cooperates with said at least second mirror to provide a second image upon said first member.

2. The mirror assembly of claim 1 wherein said first member comprises electrochromatic material.

3. The mirror assembly of claim 2 wherein said first mirror comprises a rear-view mirror.

4. The mirror assembly of claim 3 wherein said housing comprises a rear-view mirror housing.

5. The mirror assembly of claim 4 wherein said second member is transparent.

6. The mirror assembly of claim 5 wherein said at least second mirror comprises a pair of substantially identical planar mirrors.

7. The mirror assembly of claim 6 further comprising a concave lens which is wholly disposed within said housing and which is communicatively coupled to said pair of substantially identical planar mirrors.

8. The mirror assembly of claim 2 further comprising a controller which receives certain data and which, in response to said receipt of said certain data, causes said first member to be opaque.

9. The mirror assembly of claim 8 wherein said certain data is generated by use of a switch which resides within said vehicle.

10. The mirror assembly of claim 6 wherein said second image comprises an image of an area in front of said vehicle.

11. The mirror assembly of claim 6 wherein an object resides in front of said vehicle and wherein said second image comprises an image of said object.

12. The mirror assembly of claim 10 wherein said first image is larger than said second image.

13. The mirror assembly of claim 1 wherein said at least said second mirror is movably disposed within said housing.
