Patent ID: 7085323

Claim:
A method of producing an enhanced video image from an initial video image, the method comprising the steps of: enhancing resolution of an initial image component common to a plurality of temporal frames of the initial video image by processing the plurality of frames of the received video image to produce an enhanced image component, wherein the plurality of temporal frames of the enhanced video image includes a key frame corresponding to one of the plurality of temporal frames of the initial video image; substituting said enhanced image component within the key frame at a location corresponding to a location of the initial image component within the one of the plurality of frames of the initial video image; determining a movement of the initial image component between the one of the plurality of temporal frames of the initial video image and another of the plurality of temporal frames of the initial video image corresponding to a non-key frame and producing a temporal motion signal in response thereto, and including said enhanced image component within the non-key frame of the plurality of temporal frames of the enhanced video image by locating said enhanced image component within the non-key frame in response to the location of the enhanced image component within the key frame and the temporal motion signal.
