The new Nokia Lumia 920 features Pureview technology in its 8.7 MegaPixel camera with ‘Floating Lens’. The camera in the new Windows Phone 8 flagship comes with improvement of low-light photography and eliminating camera shake. Although you’ll associate Pureview technology with the Nokia 808 which featured a humongous 41 MegaPixel camera and oversampled the images to 5 MegaPixel. The 808 features lossless zoom, but these features made the device quite bulky. The second phase deals with the software trickery that explains why the image above looks so much better than the one after the break from a Samsung Galaxy S III(which Stephen Elop let ‘slip’).
Nokia’s imaging chief, Damian Dinning, has iterated that its now about the number of pixels but how you use them. Going further he explains the tech behind the second phase of Pureview. The new 8.7 MP camera used in the Lumia 920 uses a larger aperture size of f/2.0 paired with a backside-illuminated CMOS and a high pulse power LED. The camera tech also allows for greater expose, and with greater amount of light seeping through, more detail is captured.
This is not the only trickery up Nokia’s sleeve. So, you’ve never been able to capture sharp images of moving objects with your phone or good images when you are in motion. Do not despair, Nokia has come up with what it is calling Optical Image Stabilization. The new tech detects a camera’s movement with a built-in gyroscope, and compensates accordingly. What’s different with PureView is that the entire optical assembly is moved mechanically to maintain parity with what you’re shooting, which is 50% more effective in reducing shake. We’ve also got a video which compares OIS and non-OIS shot video.
