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.

Well, fortunately, pi is exactly three. :)

OP: No and yes. There are a few tricks you can try at home such as unsharp mask, edge detection, hysteris stretching, pixel averaging and gausian blur. All of those high tech 1980s digital image 'convolve matrix' tricks have been done in photoshop since the 1990s.

Plus, there are the image stacking techniques used by astrophotographers.
