Nokia Lumia 1020 vs Nokia 808 Pureview : Battle

Nokia makes the majority of the most interesting phone cameras in the world right now. And the Lumia 1020’s is its best yet. This is probably the best phone camera ever seen. However, will it succeed where its spiritual predecessor the Nokia 808 PureView failed? Let’s take a look at how these phones differ, and why the Lumia 1020 has a chance at the big time.  The story of how Nokia’s leading imaging experts, Eero Salmelin and Juha Alakarhu, sketched the concept for a 41-megapixel camera phone on a paper napkin in a Tokyo bar over a few beers in 2007 has passed into modern legend. It was their graceful solution to the problems faced with optical zoom and how it could work in a package that fits properly in your pocket. As Eero says, “It’s not difficult to do optical zoom, but how do you make optical zoom that’s good in a phone? This was the challenge we wanted to solve.” It would be another five years before the Nokia 808 PureView and its revolutionary 41-megapixel sensor was unveiled to the world at Mobile World Congress in 2012. They proved that you didn’t need optical zoom to capture amazing detail.  The team had a sneaking suspicion that they had created something special, but even they couldn’t have anticipated just how excited people were about it. They had created a genuine game-changer. “Whenever you are making a new device, you feel nervous before it lands. I can understand how an artist would feel when they spend months and years on a piece of work, and then it’s exciting to hear what other people think about it,” says Juha “You are anxious about people’s reactions and it was wonderful with the Nokia 808 PureView that they loved it.”

More power, more pixels
First of all, let’s get through the boring bits. As a phone that’s a year newer than the 808 PureView, the Nokia Lumia 1020 predictably has a much more powerful processor and higher screen resolution. Where the 808 PureView had a 640 x 360 AMOLED display the Lumia 1020 has an ‘HD’ 1,280 x 768 pixel AMOLED screen. And its single-core processor has been updated to a 1.5GHz dual-core However, there are some much more interesting and important changes to note. 
Symbian vs Windows Phone 8
The most serious tech fail of the Nokia 808 PureView was that it used the Symbian OS rather than Windows Phone. This wasn’t entirely Nokia’s fault, as the Windows Phone 7 software that Microsoft had in place at the time was hugely restrictive – putting in a PureView camera probably would not have been possible.  The issue is that Symbian was a near-dead system when the 808 PureView arrived, and seemed hopelessly clunky and out of date compared to Android or Windows Phone at the time. Nokia’s Lumia 1020 fixes all that, using Windows Phone 8 – as used in all of the recent Nokia Lumia phones.  The move away from Symbian had been a long time coming too. It seemed like Nokia was to ditch Symbian back in 2011 when it ‘retired’ Symbian branding in favour of Nokia Belle, but really this was just Nokia sprucing-up the look of the ancient system. It didn’t work, and Nokia kept on producing ostensibly Symbian-based phones until the 808 PureView, which arrived in June 2012. The reception of the first PureView phone told us a lot about what the public and phone networks think of Symbian – the 808 PureView was not stocked by any of the main phone carriers. Windows Phone 8 is a whole different situation. You’ll find phones running the OS available from all the big mobile players. It’s a much smoother, prettier and more up-to-date OS, and should give the Lumia 1020 a much better chance of success than the doomed 808 PureView. 
Same sensor style
The crucial point of similarity between the Nokia Lumia 1020 and the 808 PureView is the camera sensor, and understanding what it’s about is crucial to ‘getting’ the PureView ideal.  Both phones have 41-megapixel sensors that are the same size, 1/1.2”. This is almost three times the size of the Lumia 925’s sensor, which helps it to fit in those 41-million sensor pixels. The idea of the 41-megapixel is not primarily that you’ll create giant ultra-high resolution images with each capture. Instead, when shooting a normal picture, groups of pixels with works together as if a single pixel using what Nokia calls oversampling.  When shooting an 8-megapixel photo, for example, each pixel will have the output of around five sensor pixels to call upon. This gives it far better output than just about any other phone camera. There’s another use for the ultra-high resolution sensor – advanced non-optical zooming. When using the digital zoom with most cameras, you’re simply cropping and zooming into a part of a picture. With the 808 PureView and Lumia 1020, you crop into the sensor, so that each photo pixel still has its own senor pixel to judge its output from.Zoom in a little and each photo pixel will still be produced from multiple sensor pixels. Only at maximum zoom will each photo pixel be created from a single sensor pixel.  These single sensor pixels are a little larger than those of the latest phones, too. Fitting a 13-megapixel sensor like the Galaxy S4’s a small ‘standard’ size phone sensor gives it pixels of 1.12 microns – the Lumia 1020’s are a little bigger at 1.4 microns.  
OIS vs no OIS
This sensor is what makes both the 808 PureView and Nokia Lumia 1020 cameras so special. However, the 1020 has a second ace up its sleeve – optical image stabilisation.  This is the feature that makes the Lumia 920 and Lumia 925 cameras notable, letting them use longer-than-average exposure times for superior low-light performance. As the 808 PureView already had a sensor large enough to bring pretty good low-light performance without OIS, where the lack of stabilisation showed was in video – commence jerk-o-vision.  It’s not only movement during video capture that will be helped by OIS, though. It will also make the Lumia 1020’s zoomed-in modes far easier to use, making staying completely still much less of a factor when trying to produce sharp photos.We imagine the OIS may also be used as it is in the Lumia 925, to increase low-light performance, however we’ll have to check this out once we get a review sample in. 
4G vs 3G
In the year since the 808 PureView was released, 4G has become a common feature in top-end phones – its inclusion in the Lumia 1020 was a dead cert.  For most people, this is a connection that’s a future-proofing feature rather than a present concern, as 4G is still only available from EE in the UK, and costs a fair bit compared with good old 3G. If the Nokia 808 PureView was an interesting experiment in smartphone optics, the Nokia Lumia 1020 is that idea crowbar’d into a phone people will actually want to buy. It has the Lumia design, an operating system that people will actually want to use, and an even better camera than its inspiration. There’s little that’s not to like – let’s just hope the price is right. Sadly its US prices aren't a good sign - they're steep.
High Resolution + OIS

The 808 PureView is the obvious place to start when you’re looking for the building blocks that would lead to the Nokia Lumia 1020. However, another important milestone is the optical image stabilisation (OIS) innovation that first appeared on the Nokia Lumia 920.“We had the idea of combining OIS and the high resolution sensor pretty soon after we started working on the camera module for the Lumia 920. It made sense to combine them,” says Eero. With Nokia building new experiences on Windows Phone and the mouth-watering prospect of introducing a smartphone camera with both OIS and high resolution capabilities, all the ingredients were in place for the Nokia Lumia 1020… If only it was that easy! The next generation Developing the Lumia 1020 remained a huge technical challenge, even if the team had the experience from developing previous devices. “We had an opportunity to re-design and improve the camera module used in Nokia 808 Pureview. The camera module on the Lumia 1020 is much more advanced. The image sensor and OIS are the new generation, and there are more advanced optics, ” says Juha. “There are a lot of improvements with the algorithms too. For example, the first thing that people might notice when they take photos with the Lumia 1020 is how beautiful and much more vivid the colours are. The oversampling algorithms are much better.” Furthermore, not a single component from the 808 PureView’s camera module is used in the Lumia 1020’s.
Size + Location
Another thing that people will definitely notice about the Lumia 1020 is its sleek shape and industrial design.“When we started talking about the Lumia 1020, we saw the models and designs. We didn’t just want to make the best camera, but the best smartphone overall. Everyone felt that it looked amazing,” says Juha. Juha and Eero are also both quick to pay tribute to the imaging and product program teams in Tampere, Finland who cooperated closely. Sometimes just having everyone based in the same location can make a big difference. The pace of development and how they were able to tackle any issues or problems together was quicker because everyone was together. Our imaging heroes agree that it was the most ‘fun project’ they have worked on.
In the hands of real people
Juha has already taken thousands and thousands of test images with the Lumia 1020, but he knows that the real test will come when the public get their hands on the smartphone.  The key to the stellar imaging potential on the Lumia 1020 is the new Pro Camera interface. It unlocks all the creative potential of a digital SLR for people who don’t understand things like exposure times and ISO settings. Juha says, “We had a team building exercise and we had to think what was our dream camera user interface? We were sketching how you would have a slider for this and this… Pro Camera is our dream come true and it’s fantastic how easy it is to use.” Eero gets the final word on how Nokia managed to push the boundaries of image excellence on our smartphones. Again. “Overall, this is the best smartphone and the best camera in one device on the market today.” “Designing a leading smartphone or camera are each difficult in their own right. Designing a device that fits in your pocket, combining both of those, is extremely difficult. It’s almost impossible, but I’m proud to say we did it.”
