Abstract

Various camera arrangements are disclosed comprising a camera and an optical element. The camera is configured to record an image defined by light rays directed thereto. The optical element is configured to deflect rays from a scene to the camera for recording thereby. The optical element is further configured to deflect the rays such that, if the rays were undeflected, the rays would instead be tangent to a viewing device of predetermined shape, such as a circle. Optical elements may be in the form of curved mirrors or lenses. The camera arrangements are configured to record images in the form of left or right panoramic images of a stereo panoramic image pair, and several stereo panoramic camera arrangements are described, including one or more camera arrangements, for contemporaneously recording both left or right panoramic images of a stereo panoramic image pair.

Claims

1. A camera arrangement comprising

A. a camera configured to record an image defined by rays directed thereto;

and

B. an optical element configured to deflect rays from a scene to the camera for recording thereby, the optical element being further configured either to deflect rays such that, if the rays were undeflected, the rays would instead be tangent to a locus of positions of a viewing device, the locus having a predetermined shape or to deflect rays that are tangent to a locus of positions of a viewing device, the locus having a predetermined shape, to the camera for recording thereby.

2. A camera arrangement as defined by claim 1 in which the locus is in the shape of a curve.

3. A camera arrangement as defined in claim 2 in which the curve is a closed continuous curve.

4. A camera arrangement as defined in claim 3 in which the continuous curve is a circle.

5. A camera arrangement as defined in claim 1 in which the viewing device is in the shape of a polygon.

6. A camera arrangement as defined in claim 1 in which the optical element is in the form of a curved mirror.

7. A camera arrangement as defined in claim 1 in which the optical element is in the form of a lens.

8. A camera arrangement according to claim 1 wherein the optical element deflects rays from the scene that are incident from a range of directions to the camera to provide a panoramic image thereon.

9. A camera arrangement according to claim 3 wherein the rays are or would be tangent to the curve in a direction corresponding to a series of left viewing positions of a set of stereographic viewing positions.

10. A camera arrangement according to claim 3 wherein the rays are or would be tangent to the curve in a direction corresponding to a series of right viewing positions of a set of stereographic viewing positions.

11. A camera arrangement according to claim 1 wherein the optical element is configured to deflect rays such that, if the rays were undeflected, the rays would instead be tangent to a locus of positions of predetermined shape.

12. A camera arrangement according to claim 1 wherein the optical element is configured to deflect rays that are tangent to a locus of positions of predetermined shape to the camera for recording thereby.

13. A sterographic camera arrangement comprising at least one camera arrangement according to claim 1 configured to record rays that are or would be tangent to the curve in a direction corresponding to a series of right viewing positions of a set of stereographic viewing positions and to record rays that are or would be tangent to the curve in a direction corresponding to a series of left viewing positions of a set of sterographic viewing positions to form a pair of sterographic images.

14. A sterographic camera arrangement according to claim 13 wherein the optical element deflects rays from the scene that are incident from a range of directions to the at least one camera to provide a pair of sterographic panoramic image thereon.

15. A sterographic camera according to claim 13 wherein the at least one camera arrangement comprises a pair of camera arrangements which respectively record right and left sterographic images.

16. A sterograpic camera arrangement according to claim 15 wherein the optical elements deflects rays from the scene that are incident from a range of directions to the at least one camera to provide a pair of sterographic panoramic image thereon.
