Nokia PureView is a term getting bandied about quite a bit. The Nokia Lumia 920 is the latest smartphone to feature it but it was the Nokia 808 PureView that was the one that heralded it after the announcement at Mobile World Congress 2012. So exactly what is “it”? What is Nokia PureView?
Step a little closer, and let PL tell you a story.
Once upon a time in Barcelona, Nokia held forth the Nokia 808 PureView cameraphone in front of the people. It was a phone with the biggest image sensor in the back of it that the world had ever seen. And the people saw it, and it was good.

so far, its those two things:
Phase 1: 808

Phase 2: 920

Too bad phase 1 is 500x times better... |

we should wait for full resolution samples, but I partially agree.
I think "phase 2" wasn't supposed to be featured in a product by it self, but more likely added to Phase 1 eventually.. but they kind of ran out of tricks for the Lumias so they had to do something.
WP (just like android) is not very friendly when it comes to imaging, at least not for the stuff Nokia is trying to do, for that you need a REAL TIME OS like Symbian, that way you can sync the Xenon, the two GPU-s, etc. without any latency issues....
Still, its innovation, which seems to be a rare thing in the industry these days. |

Really? Even if it's true, is it so hard to update WP, Android so that it can do these tricks?

Sad, but true. |

No. They can't be updated .. the issue is with the kernel itself, which is the "heart" of the OS, very difficult to update in such major way, and pointless at this point.

I still think the Lumia 920 is great device but Nokia should have left out the Pureview
Phone?? What phone?? |

^And how would they differentiate otherwise ? |

So there is no point to wait for a phone with good OS and good camera. Good to know  |

As soon as someone makes a SoC that can handle the load from the 808 sensor, there will be a WP8 phone with the system.
Symbian 10.1 is a pretty good OS actually, for me personally, its the best on the market. |

I used to say in other forums
What if sony's trick about the BSI and nokia's decision of packing bigger sensors in such small modules be combined, thatd be great. And i remember being replied that it's not gonna happen ever. But it seems to me it's only a matter of time when all the pureview phases come together, my wish will come true.
I knew from the start the BSI is a good idea but sony reduced its size dramatically so the bsi effect was defeated. Sonymust release its new breed of cybershot series phones, hoping to see innovations not just noise reduction algorithms, image sharpenning algorithms and color aggravation, before nokia winds up its pureview phases together and relase a true pureview phonecam |

^ Well.. the point of using BSI sensors is the fact that you can push the size of the pixels further down. I think FSI caps out at 1.4 microns, and if you want to go smaller, you need BSI. There are issues with light reaching the FSI sensor when the pixels get too small, which is whats happening with all the newer model 13Mpix modules. If you actually have physically bigger pixels available, FSI is still the better option.. that is why all the FF DSLRs are still using FSI sensors. Also cost.. but that is another topic.
So right now its a balancing act.. BSI should be able to provide enough light, to where a 13Mpix BSI module @ 1.1 micron pixels, should yield a similar/or slightly better image quality compared to a 8Mpix FSI module @ 1.4 microns.
What Nokia did with the 808, kind of throws off what the industry has been dealing with for years. They took bunch of 1.4 micron pixels, and started combining them, and cleaning all the unnecessary information (like noise, etc.) out of there in the process. Technically, you are not supposed to have that kind of quality out of 1.4 micron FSI module.. but they found a way around it. Just look at your own night shots.. most people don't even realize how big of a technical achievement the 808 really is.
Everything is revealed when you take a shot at full resolution, then you can see the mediocre 1.4 micron pixels doing, what they do best.. creating noise.
So... BSI has a lot of potential, but it needs more work. For now, its used to help all the marketing that comes along with the "megapixel" war. It enables the OEMs to go further up in megapixel count, but at the same time keep the same sensor sizes.. which are around 1/3" for most smartphones. All in all, for us the consumers, all of this doesn't do anything really.. we still end up with the same shitty quality that we've been getting for years..

It's not true that phase two is not on par with phase 1!
When the Lumia 920 gets out, this will all be clarified!
I was at first all disappointed too. But turned out Nokia achieved more than they sold us at first! They need to learn some marketing tricks from Apple. 
Anyway, been there, saw what the 920 is capable of, had my D7000 with me, did my own tests on the same set-up. I know what I'm talking about. Wait and see..
But just a clarification about the key points each phase is about:
Phase 1 with 808:
- 3x lossless zooming. Amazing achievement, very handy. Though the quality of the zooms is not something that special.
- 5MP or 8MP PureView photos. Very low noise levels, incredible detail on par with high-end cameras. However, in normal lighting, only pixel peeopers would care about that. If you wanna end up printing that on a 15x10 photo, or uploading it online, the 808 or even that photo of a professional DSLR won't make a difference!
The key point was in reduce noise levels in low light. But that's where the 920 shines! It blows the 808 out of the water. And it's the one area all cameraphones struggled with since eternity!
808 has the Xenon advantage of course for flash photos. But the new fast pulse LED is said to come close to Xenon performance. We shall see about that. Asked to test that but there was no good set up for such a test.
**Note that a normal photo shot by high-end DSLR at daylight doesn't lead to any significant differences over any compact camera or a cameraphone. But using some features/options with such cameras does make some impossible photos with compacts possible. Either by using filters, specialised lenses, or doing bokeh photos, or professional portraits, etc..
But overall, the you get the idea.
Phase 2 with 920:
- As mentioned, low light photography.
- Professional video stabilisation.
