MIT imaging chip creates natural-looking flash photos
Mobile image processing in itself isn't special when even high dynamic range shooting is virtually instant, at least with NVIDIA's new Tegras. A new low-power MIT chip, however, may prove its worth by being a jack of all trades that works faster than software. It can apply HDR to photos and videos through near-immediate exposure bracketing, but it can also produce natural-looking flash images by combining the lit photo with an unassisted shot to fill in missing detail. Researchers further claim to have automatic noise reduction that safeguards detail through bilateral filtering, an established technique that uses brightness detection to avoid blurring edges. If you're wondering whether or not MIT's work will venture beyond the labs, don't -- the project was financed by contract manufacturing giant Foxconn, and it's already catching the eye of Microsoft Research. As long as Foxconn maintains interest through to production, pristine mobile photography won't be limited to a handful of devices.

Noise Free Wireless alleges Apple is tone deaf over sound reduction patent, files lawsuit to match
Apple faces litigation claiming that it's using patented technology all the time, often from small patent holding companies with dollar signs in their eyes. Noise Free Wireless has just filed a patent lawsuit against Apple whose allegations are considerably, well, louder. The firm maintains that it had been pitching its patented noise cancellation to Apple in periodic meetings between 2007 and 2010, only to watch as 1 Infinite Loop used Audience's technology for the iPhone 4 instead -- and supposedly handed some of Noise Free's work to a competitor. An Apple patent filed the same year borrows some of that work, Noise Free insists, in addition to the iPhone in question. Neither side is talking about the details to outlets like Macworld, although we'd be cautious about accepting either company's position at face value. However much Apple may protest its innocence regardless of circumstances, Noise Free certainly has a vested interest in retribution after losing out on such a big contract.
