There is a hot discussion going on where everybody is on Nokia to find out the difference between the Nokia Pure View of 808 and Pureview which is coming in 920. In this post I am trying to interpret the official document to answer my queries and what I have received over emails and from friends.
Better Images under Lowlight :
Nokia Classifies PureView in 808 as Phase 1 and Pureview in Lumia 920 is Phase 2. So, lets read the quote from Nokai PureView Phase 2 document :
This second development phase of PureView is therefore focused on exactly that – a significant improvement in low light whilst also making it available to a wide range of people.
I can interpret this in two ways :
- Making it possible with less Mega Pixel : Nokia knew that the Snapdragon processor that will be used in Windows Phone 8 will not be able to support high megapixel camera like 808 and hence they wanted to get it done on low megapixel camera.
- Price Factor : Even if the processor would have supported, Getting a 41 MP camera would have definitely increased the cost of the device which means a wide range of people would have never got it.
Thanks to Better ISO performance on newer BSI (Back Sie Illuminated) Sensor which is better low light performance a.k.a Good Picture and close to proper exposure even in low light condition. This is achieved by Providing Area allowing more light to come in through , so more light = more bright and exposed image.
So the Pureview Technology in Nokia Lumia 920 brings in the answer to the question ” If Smartphones can capture better images in low light” and you can really see that there is nothing fake about it and it works flawlessly and its competition stands nowhere.

Video Stability :
The second advancement made in Phase 2 of Pureview is the Video Stability which you already saw in the above video which is again no fake. Pureview of 808 has poor video stability and this was one of the customer requirement, similar to good photos on dim light. Pureview Phase 2 actually answers that by using Optical Image Stabilizer (OIS).
OIS is a feature which prevents shaky / blurry picture or video where the sensor is stabilized keeping your movement in mind i.e. When you move , the camera moves its sensor / lens so that the shake can be avoided by compensating the movement , though this cannot guarantee a good / shake free video every time but helps you in stabilizing a bit more.
Now lets take on the difference between two of the Pure View :
Also worth mentioning :
- Nokia Image Processing its their own propriety algorithm which improves image quality on low light by reducing the noise. This was developed working closely with Microsoft and allows the heavy integration of Nokia’s wide range of image processing algorithms including autofocus, auto exposure and auto white balance, to name just a few.
- Next generation LED flash : This is another component which improves picture quality which uses powerful short burst lighting which in turn act as 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 useful when you want to capture a moving object.
