Can ordinary humans enhance blurry pictures yet ?
TerraHertz:
In youtube, search for "unblur image in photoshop"
You'll be surprised.
"windows 10 picture viewer" ??? Surely you jest?

There's more than one way to skin a cat . my apologies to all cats. but
electronic circuit you are seeking may have other ways to extract what you are seeking.
if its only a missing resistor value, by deduction. looking at other known circuits of the some or similar

You could really stand to leave people a benefit of a doubt...
I read it as sarcasm--well, I hope I read it correctly as sarcasm, at least. :P

If people choose to post nonsense in a public forum and think they're clever, expect to be corrected. Its about as silly as the often repeated "but scope screens only refresh 60 times per second", a measure entirely unrelated to the sampling rate of the signal acquisition, or other characteristics also measured in Hz.
With a good model of the sensor we see all sorts of clever things like stabilization, rolling shutter motion compensation, flicker removal, etc. All built into the live processing path on photo and video cameras. Mostly proprietary stuff and completely invisible to the end user.

We are not yet seeing sound being picked out of the image... I'm looking forward to the live demonstration! :D

I seem to remember --- vary vaguely --- an hypothesis that ancient sounds can be preserved in tacky surfaces in the same way that sounds are preserved in shellac cyclinders and records. Okay, I'm not sure how you would make a machine to extract those ancient sounds, ( petra-hertz? ), but in theory you might just hear the last words of the people of Pompeii.

Unbluring is slightly different from enlarging - in the former case the information should be in the picture, just in the wrong place and depending on how the blur is caused there are mathematically sound algorithms for recovering the correct image.
Increasing the pixel resolution of an image needs new information to be extrapolated from what is there. In some (limited) cases (say a line drawing) this can be done surprisingly well but the general case is harder.
