It's an interesting question. I have personally seen image
deconvolution bring out-of-focus images back into focus and images
blurred by camera motion brought back to clarity. So I have high hopes
for digital processing eventually dealing with diffraction and lens
aberrations. Eventually. The first paper I read (which showed examples of successful re-focus and de-blur deconvolution) was published in the Proceedings of the IEEE in 1968.

Some times mathematically predictable image distortions can be reversed by some complex video processing. Is this true for diffraction? Or does the attempt mostly just cause ringing like many sharpening or edge enhancement algorithms? - Tom Mark Schubin wrote:A lot of people have asked for my AES, IBC, and HD World PowerPoints from my presentations last week.
