Abstract

Disclosed is a method for providing a combined image from a plurality of images each produced by one of a plurality of cameras. Each camera has an image system for taking an image of the plurality of images. The method comprises generating the plurality of images in each of the plurality of cameras and stitching the plurality of images to form the combined image using a stitcher disguised as a virtual camera.

(a) generating the plurality of images in each of the plurality of cameras;

(b) using a virtual camera to perform a stitching operation on the plurality of images to form the combined image.

9. A method as claimed in claim 8, wherein stitching is by warping each of the plurality of images into an intermediate co-ordinate, and stitching the plurality of images into the combined image using a two dimensional search.

10. A method as claimed in claim 8, further comprising performing overlap calculations to determine overlap regions of the plurality of images, the overlap calculation being used for all subsequent pluralities of images from the plurality of cameras.

11. A method as claimed in claim 10, further including:

(a) using the overlap calculations to perform colour correction in the plurality of images; and

(b) maintaining the colour correction for all subsequent pluralities of images from the plurality of cameras.

12. A method as claimed in claim 10, further comprising selecting a presentation style for the combined image.

13. A method as claimed in claim 11, further comprising selecting a presentation style for the combined image.

14. A method as claimed in claim 11, wherein stitching is by warping each of the plurality of images into an intermediate co-ordinate, and stitching the plurality of images into the combined image using a two dimensional search.

15. A method as claimed in claim 12, wherein stitching is by warping each of the plurality of images into an intermediate co-ordinate, and stitching the plurality of images into the combined image using a two dimensional search.

16. A method for providing a combined image from a plurality of images each produced by one of a plurality of cameras each having an image system for taking an image of the plurality of images, the method comprising:

(a) generating the plurality of images in each of the plurality of cameras;

(b) warping each of the plurality of images into an intermediate co-ordinate; and

(c) stitching the plurality of images into the combined image using a two dimensional search, stitching being by a stitcher disguised as a virtual camera.
