Using change of scene to trigger automatic image capture

Abstract:

A series of frames or live images received by a camera can be processed by an automatic image capture system to determine when an automatic image capture should take place. The system can detect when a scene change occurs by comparison of data for two or more frames. If a scene change is followed by a stabilization of the scene, the system can trigger an auto-capture of the stabilized scene, without the need for user input.
