Now have a look at following picture posted by Anandtech in Lumia 920′s hands-on from yesterday’s event. Anandtech explains about the above image. Nokia had a scene setup in the dark to test the Lumia 920′s low light camera performance. A vase with flowers was set inside a dark box with a port big enough for you to get a smartphone inside. Without using a flash or a tripod, low light performance of the 920 was pretty impressive. It is rightly said a picture is better than thousand words. iPhone 4S was not able to even detect the flower vase in above comparison and Lumia 920 presents a full good-looking picture of Flower base. Amazing, isn’t it ? Nokia is certainly going to set a benchmark in low-light imaging with Lumia 920′s pureview camera it seems!! Now let see how Nokia explains this great low-light performance. Next Generation Back Side illuminated sensor (BSI). BSI sensors use a reversed structure, so the wires and metal are in the base of the sensor and the photosensitive diodes are directly below the micro lenses and colour filters. This results in more photons reaching the photosensitive diodes [pixels] and therefore superior pixel performance, most notably in low light. Wider Aperture F2.0 for getting more light in. Nokia used sensors are at least 10% larger than comparable sensors of the same resolution to accommodate the true 16:9 aspect ratio, this was even more of an optical design achievement than other cameras with a smaller sensor area. Optical Image Stabilisation (OIS). OIS works by detecting camera movement using a gyroscope – a highly accurate sensor used to detect the degree and direction of movement. Rather than a single lens element being shifted to compensate for camera shake, Nokia’s OIS system moves the entire optical assembly in perfect synchronisation with the camera movement, or to be more precise, unintended camera shake. The benefit of this approach is that the amount and form of camera movement that can be compensated for is much greater. Adding up all of the advantages of Nokia’s OIS system means camera shake in lower light can be compensated for to lower lighting levels than conventional OIS systems, ultimately resulting in low light photography. Check the graph below which shows how OIS ( the orange line) helps in maintaining Image sharpness. Now coming to second aspect of the PureView on Lumia 920, which is Steady video in all lighting conditions, let see how Nokia explains that. The advantages of OIS are not constrained to just still images in low light. OIS can also help provide one-handed usage. Sometimes capturing pictures or video one handed is more convenient and natural. However, even in reasonable lighting, this typically results in camera shake. This really helps to extend the spontaneous use of smartphones as a modern method of capturing moments as they occur during everyday life. By detecting the different movements the OIS system is able to compensate for unintended movement rather than intended movements e.g. panning. One of the most important aspects of good smartphone video recording is smooth recording. Capturing smooth video whilst moving can be extremely difficult. Even ensuring small movements are unnoticeable during playback can require constant concentration. This often results in video recording becoming tiring, other than for the shortest of video clips. In addition, for the individual who’s recording it, it detaches them from the ‘live’ action as they concentrate continuously on the viewfinder. When capturing video OIS works slightly differently to when capturing stills. Other major improvements are also there which add to overall performance of the Camera. Next Generation Dual LED flash with a pulse flash burst. This provides a similar capability to xenon flash where the flash fires a short single flash of light. This flash is short enough in duration to effectively freeze subject movement. Whilst the duration of the flash is still not as short as a xenon flash, it is short enough to provide a sharper picture of moving subjects than conventional LED’s which provide no such benefit. Nokia Image processing Technology. One of the most important new algorithms is our new denoise algorithm for reducing visual noise, which helps to further improve low light performance while keeping the image very natural. In the beginning of the project, we set ourselves a challenging target to create a product with the best low light performance ever in a smartphone, even in natural light. Every single part of the system was pushed for this goal: large aperture, new image sensor technology, optical image stabilizer and new image processing algorithms. When the technologies are combined, the improvements add up, and finally we have the results in our hand.

link2alok, 20 Sep 2012indeed i agree ... but sadly in that case ppl will be drifting towards the the android phones... morethe same people wud know that lumia is a lot better than the previous lumias.why-920 is much popular wid the innovations it has introduced.it has got a gud gestation period till it launches.things always do not stay the same!
New low-light comparison video between Lumia 920, iPhone 4S, 808 PureView and SGS III.
Wheez, 20 Sep 2012No single phone will ever kill something as big as iOS. If WP8 phones would be a huge success,... moreNo wont kill iphone overnight but overtime IOS will die.FOlk change get bored and try new things..Nokia ,Palm,BlackBerry,Windows where tops 10 years ago now almost gone..Apple and Android will fade as the fresher new O/S come along such as W8 and QNX from BB these are fresh written from ground up..Things do go in cycles and soon having the smallest phone possible will become trendy again..This could happen with pull out screens.
Ichimaru, 20 Sep 2012Sadly it can't be 30K coz the Lumia 900 is costing 33K in India :-(indeed i agree ...
but sadly in that case ppl will be drifting towards the the android phones only....
why would one take a risk , when Lumia ancestor have performed sluggishly slow against the same configuration Android mobiles .
I am a fan of nokia boss, but with high price tag it might loose the charm....
Hope they will release it soon, but not before november... WP8 is not ready yet, htc WP8 devices are not released before november either.
Any one any idea about the pricing....
I wish it close to 30 k range or else people will still go for android phones from samsung, HTC and sony ...
I actually want Nokia to release this phone ASAP. I wish I can have one today.
GSMarena team, please reply me, why have you forgot to add Dolby Digital Plus feature in the specification? This device has Dolby Digital Plus feature too. Please see the Nokia official websites for confirm that.
or, please explain us what is the real deal.
TJ, 20 Sep 2012Nokia needs to start the pre-orders, if they don't i believe people will start buying other ph... moreyou are totally right my friend, I shifted to lumia 920 from acro s but I don't have any choice except sony acro s if they didn't release in 1 month :(
Wheez, 20 Sep 2012No single phone will ever kill something as big as iOS. If WP8 phones would be a huge success,... moreno dude u r mistaken.its ios that ms targets....but this wud take atleast 10 years-no doubt ios is ahead of even droid in development and ios is too big to be eaten by the fragmented and not 100% lag free,power hungry android.but wp is less power hungry and can even beat ios-nokia understands its potential and thats why they didnt go for android so as to become long term players in the game.if wp has its way ios share of smartphone revenue wud b reduced to 25 % within 5 years-given wp was built parallel to ios and now its getting better than it.
