Video image compositing techniques
First Claim
1. A method for processing video data in a plurality of different sequences of frames thereof, each frame in a particular sequence of frames including relatively motionless background data representing at least a part of the entire relatively motionless background data in said sequence and moving object data representing moving objects in said sequence, said method comprising the steps ofstoring the background and moving object data in each frame of a particular sequence of frames;
- aligning common portions of the stored background data in each frame to provide stored combined background data which represents a composite relatively motionless background image which contains substantially the entire relatively motionless background data in said sequence and is at least as wide as the background image in any one frame of said sequence thereof;
processing the aligned background data to remove the moving object data therefrom;
storing said processed background data as combined background data representing said composite background image.

Abstract
A method of processing video data created for display in one aspect ratio in a plurality of different sequences of frames thereof, each frame in a sequence containing background data which represents at least a part of the same relatively stationary background data in the sequence. The background data in each frame of a sequence is stored and processed so as to produce combined background data representing the background image in the sequence in a different aspect ratio, without the presence of moving objects therein. Data representing moving objects in each frame of a sequence are stored together with selected portions of the background data which surround the moving objects in each frame. The data representing moving objects in each frame are correctly positioned in the combined background data, which is used for each frame of the sequence, by matching the selected portion of the background data surrounding the moving objects with corresponding portions of the combined background data to determine the correct positions of the moving objects in the background image. The background data and the matching portions of the moving objects are composited in accordance with such correct position determination to form a composite image for each frame in which the moving objects are correctly positioned in the combined background image.
