Claim One:
1. A method for automatically framing and tracking an object of interest using a video camera integrated into hand-held processing devices including PDAs, mobile telephones, palmtops, and portable computers to insure stability of the image content as a user manipulates the device, the method comprising the steps of: providing said video camera with a wide field of view; continuously detecting relative movement associated with the hand-held device that tracks the object of interest within a displayed image generated by said camera, the relative movement depending on the tracking of the object of interest; and continuously electronically adjusting the camera, without use of a motor, in response to the detected relative movement, so as to maintain a desired framing and tracking of the object of interest within an image and/or successive images, as long as the image or images remain in the field of view generated by the camera for selectively providing either one of a still picture of the object or video image of the object, respectively, for providing a stable image in the presence of movement of a user's hand holding said device; wherein the framing of the object involves creating a model of the object; and wherein the model is adjusted based on a history of prior obtained plurality of calibration parameters used to represent one or more matrices used for the framing and tracking of the object.
