No, you can still do that.

Blurring isn't a matter of removing data or limiting the data that's captured. Motion while taking the picture, or even focus problems, are a matter of capturing the same amount of data, only smearing some of it together so they get confused.

If you can figure out how to sort through that smeared data and accurately discern HOW it was smeared, you can restore a lot of that data to an organized (sharp) picture.

CSI Enhance is all about putting data in that was never captured discreetly in the first place. When I expose a pixel on a CCD or CMOS chip, no amount of algorithmic wizardry will be able to figure out what the pattern exposed on that pixel was. Because the pixel reports it as a single number.

Yeah, I heard about this a little earlier. It's not very surprising considering some of the tech demos we saw in previous years, but it IS very impressive from what I've seen so far. That said, Photoshop's content-aware fill was unveiled to similar ooh's and ah's, and that turned out to just be "okay" in every day use.

Let me know when they add 'Uncrop'.

There was a program I used back in college and now I can't remember what it was, but it gave the option to "sharpen image" and that always deblurred my images for me...and that was, what, 7 years ago? edit I'm pretty sure it was some software that came with my Kodak Easyshare camera ca.2003/2004-ish?

Kate, this is nowhere near the same level as detecting edges and sharpening them. This algorithm actually recognizes the motion of the camera during its exposure, and reverses it. It's a HUGE advancement if it ends up working as well as it looks.

'Super advanced algorithmic wizardry' could Google a similar picture, look for patterns, and fill in the blanks. If a person can figure out how to draw what's inside zoomed-in pixels, a computer one day could too.

It was hard to see in the video what they were doing and I only watched the first couple of minutes.
