Processing of images to represent a transition in viewpoint
First Claim
1. A method of making an output sequence of images representing a transition between two input images or image sequences where the two input images or sequences of images include views of a common scene from different viewpoints, comprising the steps of creating transformed images or image sequences having an apparent point of view that moves along on a path joining the viewpoints of the two input images or sequences of images, wherein geometric transforms that vary over the said output sequence are applied to at least some input images or sequences of images so as to create said respective transformed images or image sequences and including the transformed images or sequences of images in the said output sequence of images.

Abstract
When mixing cutting between video cameras viewing a common scene from different viewpoints, geometric transforms that vary from image to image are applied to one or both camera outputs so as to create an apparent point of view that moves along on a path joining the viewpoints of the cameras.
