Nokia's Damian Dinning goes in-depth on phase two of PureView for the Lumia 920 (video)
Nokia's imaging chief Damian Dinning has released a paper explaining the "second phase" of PureView technology that's included in the new Lumia 920. Charged with improving low-light photography and eliminating camera shake, the experimental 808 handset was developed with a 41-megapixel sensor that oversampled images down to 5-megapixels. However, such equipment is bulky and expensive, so it changed tack for its second crack at the whip, which you can find out about if you join us after the break.
Cornell University's microscopic camera makes photos with mathematics
Megapixel, megaschmixel -- we're more impressed when camera tech goes the opposite way and shrinks down. A happy byproduct of his neural mapping research, Patrick Gill and his Cornell University team have engineered a cam so microscopic it could fit on the head of a pin. The lensless creation is only one 100th of a millimeter thick, looks more like a miniature CD and doesn't require any budget-breaking parts. Named after the Fourier transform that inspired it -- a mathematical operation that breaks a signal down into various frequencies -- the Planar Fourier Capture Array translates pixel components into a fleshed-out image. Creators of the tiny camera tech stress that it won't be "[taking] family portraits," but you could probably count on having this nigh-invisible sucker implanted into your brain. It's definitely one small step for man, one nano-leap of the photographing kind.
Olympus exec declares "twelve megapixels is enough"
The megapixel race has been declared over plenty of times before, but we're guessing that there will be more folks than ever in agreement with Olympus exec Akira Watanabe's recent statement that twelve megapixels is "enough for covering most applications most customers need." In addition to that blanket declaration, Watanabe said that Olympus has "no intention to compete in the megapixel wars for E-System" (its line of DSLRs), adding that it would instead focus on other features like dynamic range, color reproduction, and a better ISO range for low-light shooting. On that latter front, Watanabe predicts that autofocus could be one of the big areas of innovation in DSLRs, with current "phase detect" systems giving way to new and improved image sensor-based autofocus systems. So, what do you think? Is twelve enough, or is the more megapixels the merrier? Sound off in comments.[Via Ars Technica]
Games shoehorned onto a digital camera
What features do you look at when buying a digital camera? Megapixels? Battery life? White balance override? How about games?We can't really imagine the consumer who will be swayed to buy the DXG-589V because of what the press release describes as "20 built-in full-color 2D or 3D video games." If a consumer is interested in playing games on the go, they can already buy a portable gaming system or download some games for their cell phone or PDA without denting their bank account too much. If they're not interested in games, then the promise of being able to play what will likely end up being derivative ports directly on their digital camera isn't likely to turn them into instant gamers.We also can't imagine that Sony will be too happy with the colored shapes being used as control buttons on the camera, which bear a striking resemblance to the arrangement the PlayStation line has been using since 1995.

Pogue's perspective: megapixel numbers don't matter
David Pogue has faced his fair share of myth-busting duties, but his latest assignment sure didn't have to be done in order to convince us that his unanimous discovery was indeed correct all along. While theorists (and those adamant that bigger always equals better) can theorize forever on why additional megapixels should yield clearer, more accurate prints, the reality of the matter is that extra megapixels are typically not much more than a marketing ploy to lure consumers into making an additional purchase. In his latest test, he took identical photos with anonymous 5-, 8-, and 13-megapixel shooters, and then printed them out on 16- x 24-inch poster paper at a professional photography lab. Then, he surveyed the general public in Times Square to see if the naked eye could actually discern between the varying sensors and the level of clarity -- to no surprise (and to theorists' chagrin), only a single person (a photography professor, mind you) correctly sorted the prints in order of megapixels, and Pogue even asserted that the lucky winner was probably guessing anyway. So, if you still don't believe us, be sure to hit the read link for the full skinny, and save yourself a few bills the next time you're camera shopping by not making megapixels your ultimate priority, capishe?[Via TheRawFeed]
