Abstract
Enhanced resolution video sequence results from construction of enhanced resolution key frames and synthesis of enhanced resolution non-key frames. Key frames are constructed by processing a plurality of initial resolution frames in order to produce the enhanced resolution image components of the key frame. Non-key frames are synthesized using the enhanced resolution image component of the key frames and image component motion determinations from initial resolution frames using an image warping technique. Non-key frame image components are further improved by blending and error correction processes.

A method of producing an enhanced video image from an initial video image 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;
- and
- incorporating said enhanced image component into a plurality of temporal frames of said enhanced video image.
A device for producing an enhanced video image from an initial video image, comprising:
- a key frame generator for enhancing resolution of an initial image component common to a plurality of initial temporal frames of the initial video image by processing the plurality of initial temporal frames to produce an enhanced image component and for incorporating the enhanced image component into a key frame included within a plurality of enhanced temporal frames of the enhanced video image, the key frame corresponding to one of the plurality of initial temporal frames;
- and
- a non-key frame generator coupled to said key frame generator for incorporating the enhanced image component into a non-key frame included within the plurality of enhanced temporal frames, the non-key frame corresponding to another of the plurality of initial temporal frames.
A computer readable medium including computer instructions for producing an enhanced video image from an initial video image, the computer instructions comprising instructions for:
- 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;
- and
- incorporating said enhanced image component into a plurality of temporal frames of said enhanced video image.
A display system for displaying an enhanced video image from an initial video image, comprising:
- a key frame generator for enhancing resolution of an initial image component common to a plurality of initial temporal frames of the initial video image by processing the plurality of initial temporal frames to produce an enhanced image component and for incorporating the enhanced image component into a key frame included within one of a plurality of enhanced temporal frames of the enhanced video image, the key frame corresponding to one of the plurality of initial temporal frames;
- a non-key frame generator coupled to said key frame generator for incorporating the enhanced image component into a non-key frame included within another of the plurality of enhanced temporal frames, the non-key frame corresponding to another of the plurality of initial temporal frames;
- and
- a display apparatus coupled to said non-key frame generator for displaying the enhanced video image.
