Microsoft algorithm uses six-axis motion sensors to fix blurry snapshots, inadvertently pimping your ride
Trying to snap a shot of your cherry red Mazda, but can't keep your hands still? You'll find all the tech you need to smooth things out in an iPhone 4 or (MotionPlus-equipped) Nintendo Wiimote. Experimenting with 6DOF inertial measurement sensor packages, scientists at Microsoft Research have developed a software algorithm that literally records your exposure-destroying shake via accelerometer and gyroscope, then magically removes the blur by canceling it out. While the technique still isn't perfect -- spot ghostly line above some of those background cars -- the Microsoft researchers compared their results to other in-progress algorithms, and we think you'll agree this new solution presents the best results by far. It's a shame Microsoft doesn't say when we'll see the tech in a spiffy DSLR attachment, or better yet a cameraphone.

Mitsubishi develops "flutter shutter" for deblurring pics
Recent projects are really putting the hurt on bluriness. We saw camera shake take a big hit with the recent MIT project that uses a fancy algorithm to sharpen a picture, but does nothing for moving objects. This new tech from some Mitsubishi tackles the motion blur problem thanks to a relatively simple "flutter shutter" attachment on the actual camera. Their device uses a coded exposure sequence to cut a normal exposure into short burst, allowing processing software to sharpen any fast moving objects in the picture. The prototype is based on an 8 megapixel Canon PowerShot Pro1, but the method can apparently be applied to any camera, and would even work as a built-in feature on a consumer cam -- though it'll probably be a few years before it trickles down that far. In the more immediate future the tech seems a great fit for security cameras, since the system can help decipher blurry license plates. Senior research scientist Ramesh Raskar likened the method to a UV filter or a polarizing filter, and based on Mitsubishi's examples of the flutter shutter in action, the tech could really be a boon to all sorts of photography.
Researchers develop algorithm to combat photo blur
Since it's unlikely that your hand will get any steadier with age, and we probably won't see optical image stabilization in cameraphones anytime soon, researchers are concentrating on ways to fix your crappy photos once they've already been captured. The latest salvo in the war against so-called hand motion blur comes from a team of computer scientists at MIT and the University of Toronto, who have developed an algorithm that can create a sharper picture by "estimating the distribution of a number of probable images" and coming up with a happy medium. Introduced at this year's Siggraph Conference in Boston, the algorithm could potentially be included in future versions of Adobe Photoshop -- which currently fights blur with a rather ineffective unsharp mask tool -- although it will do nothing for blurring caused by moving objects or improperly-focused shots. Unfortunately, it sounds like this product is still at least a year away from commercial release, so tripods and nerve-steadying Pentazemin are still your best bets for the time being.[Thanks, Alex]
