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 responding 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; a plurality of image primitives, each of said image primitives comprising a matrix of video data words; means for convolving each of said image primitives with said point spread function to generate a set of blurred image primitives; means for computing the correlation between each of said blurred image primitives and a segment of said synthesized video frame and detecting a peak correlation therefrom wherein said segment is a selected portion of said synthesized video frame; a memory for storing a mosaic of selected image primitives; and means, responsive whenever said correlation means detects a two-dimensional peak correlation between a particular one of said blurred image primitives and one segment of said synthesized video frame, for writing a particular one of the unblurred ones of said image primitives into said image primitive mosaic storage memory at a location corresponding to the original location of said particular synthesized video frame segment in said synthesized video frame.
