The closest things to this that I know of in Real Life are:

1.  The various "Sharpen" filters in PhotoShop.

2.  Published work on fractal interpolation of images.

3.  Computational corrections applied to compensate for construction flaws
in the mirror of the Hubble Space Telescope.

  Note that neither 1 nor 2 can hope to reveal details not actually present
in the original shot.

  I think what you've seen has mostly been a dramatic special effect, and
not real technology that you can buy (at ANY price).
