Claim One:
1. In an imaging system comprising an imager which may view a scene through an aperture characterized by a point spread function and means responsive to said imager for generating successive frames of video data words characterized by a first sampling rate, a system for enhancing image resolution, comprising: means for converting said video data words into a synthesized video frame of video data words, said synthesized video frame characterized by a second higher sampling rate; means for enhancing the resolution of the image represented by said synthesized video frame, comprising: means for convolving said synthesized video data words with said point spread function to generate a video data word corresponding to a twice-blurred image; means for subtracting said twice-blurred image video data word from a corresponding one of said synthesized video data words to obtain a video data word corresponding to a degradation estimate; and means for adding said degradation estimate video data word and said corresponding one of said synthesized video data words to obtain an enhanced image video data word.
