Abstract:
1. A digital video camera providing a composite video image having multiple focal lengths comprising: a multi-focal lens system capable of observing a scene; a drive mechanism capable of moving the multi-focal lens system through a cyclic path, wherein the multi-focal lens system forms a plurality of optical images as the multi-focal lens system moves through the cyclic path, each optical image corresponding to one of the plurality of focal lengths; an image pickup device capable of converting each of the plurality of optical images into a corresponding image signal, each image signal including a plurality of pixels representative of the scene; an image processor operative to: pan and tilt movement tracking sensors providing pan and tilt information to the image processor to facilitate identification of the sets of corresponding image elements, said pan and tilt movement tracking sensors tracking changes in the scene due to movement of the multi-focal lens system or movement of the scene; wherein all of the multi-focal lens system, drive mechanism, image pickup device, image processor and pan and tilt movement tracking sensors are within the digital video camera.
