We’ve got a few more details on the Nokia Lumia 920 for you including more specs on the camera which is an F2.0 device that can take in “five times more light” than competing smartphones. Impressive!
The floating lens is effectively a camera unit (not lens) mounted on springs which we assume dampened in some way. Update: This is an active system driven from data obtained by a gyroscope.
Here’s a demo that Nokia was showing at the press event. The images are designed to show the difference between the image you’ll get from a standard smartphone and the image you’ll get from a Nokia Lumia 920 with PureView and the floating lens.
“Up to 50% more effective than many high end digital cameras.” Nokia says on the optical image stabilization system.
The Nokia Lumia 920 is the flagship Windows Phone 8 smartphone, including the latest advances in Nokia PureView imaging innovation. Using advanced floating lens technology, the camera in the Nokia Lumia 920 is able to take in five times more light than competing smartphones without using flash, making it possible to capture clear, bright pictures and video indoors and at night. It also compensates for hand movement while the photo is being taken.

Nokia’s new OIS system can cater for around 50% more
movements per second than conventional OIS systems – up to around 500
movements every second!
A gyroscope is used to monitor movement – the system is active, not passive.
“we’ve found in testing that shutter speeds as long as 1/4th second can be used. This is a 3EV improvement or 8x longer shutter speed — which we believe to be a new benchmark!” We believe that equates to 1/3rd second shutter speeds based on what Nokia are saying in their white paper.

“To bolster the low light performance, we’re
introducing a new generation LED. It provides the benefit of being able to be used as a
continuous light source e.g. for video or as a highly popular secondary function; a torch
and now for the first time – a pulse flash burst”
