There's more to the 920's camera... this pdf has lots of Pureview information. But here's some of the more interesting stuff for the lazy :D
- Nokia is using a custom BSI 8.7MP sensor. This sensor can provide true 16:9 and 4:3 aspect ratios, which Nokia claims is "unique among smartphones" (e.g. the T-mobile MyTouch has a 5mp camera that takes 4mp pictures, thanks to 16:9 cropping of 4:3 images). Nokia's sensor is also "at least 10% larger than comparable sensors of the same resolution."
- Next generation LED flash. Nokia is using LED flash to provide a constant source of light, e.g. for use as a flashlight/torch and for low light videos. But, they are also using a "pulse flash burst" to mimic the effect of xenon flash. It is supposed to provide "a sharper picture of moving subjects than conventional LED’s."
- Nokia claims their optical stabilisation can deal with "around 50% more movements" than more conventional systems in digital cameras, or around 500 movements per second. While other smartphones have digital stabilisation, Nokia is the first to do it in hardware.
- Shutter speeds slower than 1/30th of a second often result in shaky photos. With optical stabilisation Nokia claims shutter speeds as long as 1/4th of a second are usable ("3EV improvement or 8x longer shutter speed"), which makes for great long exposure shots in the dark.
Sounds pretty innovative to me. Although, it would probably impress me more if I actually knew more about digital photography :happy: I don't know much about shutter speeds or exposure .

Imagine if a device comes out next year that includes all known PureView tech. Combine the 808 and the 920. Bam!Talk to me about Windows Phone, Windows 8, XBOX, art, animation, design, or anything! Be sure to follow me on Twitter and friend me on Facebook (say you're from here or I may not accept)

The entire camera assembly is held by a set of tiny springs and the system takes in information from the gyroscope in order to determine if the phone is moving, the speed of movement, the direction, etc... The springs compensate for much of the movement.
This, combined with software image stabilization makes for a pretty potent combination.Talk to me about Windows Phone, Windows 8, XBOX, art, animation, design, or anything! Be sure to follow me on Twitter and friend me on Facebook (say you're from here or I may not accept)
