There are algorithms in computational photography that effectively "stack" multiple images of the same thing in order to achieve a kind of 'super-resolution'. It's been a bit since I've done any of that, so I do not recall, but my hazy memory says its pretty straight forward linear algebra (and has the concomitant drawbacks that algorithms of this type have).
