Dolby reveals audio secret of new phone’s success .

Dolby Headphone demo 

BARCELONA, Spain –You perhaps won’t be surprised to know that there was very little noise at the Dolby stand at Mobile World Congress. Just a lot of people standing around with headphones on and big smiles.

The audio tech giant was first on our list of Nokia partners to visit after we learned that they had supplied the sound software for the new award-winning Nokia 808 PureView.

Taking pride of place at their stand, the world’s best camera phone owes much to Dolby technologies for helping to make it an HD mobile entertainment device.

For the PureView is also about pure audio thanks to its high-definition Dolby Digital Plus 5.1-channel surround sound which plays on HD TVs, and home theatre systems, and when combined with Dolby Headphone technology – also built into the PureView – provides a personal 5.1 surround experience over any headphones.

Nokia is also bringing the Dolby  experience to other smartphones with Nokia Belle Feature Pack 1 software upgrade for the Nokia 700Nokia 701, and Nokia 603, also displayed on the Dolby stand.

Mobile Sales Director Shawn Richards talked us through the tech on a Nokia 700 with a demo from Batman movie The Dark Knight.

He explained that the Dolby Headphone upgrade transforms stereo content into a personal surround sound.

“You get a more natural, engaging, and authentic sound,” he said. “Good audio is even more important when you are watching a movie on a small screen. And Dolby Headphone creates a totally immersive feel.”

I popped on the headphones and gave it a try. Sure enough, the action sequence, complete with explosions at the back of my head and voice front and centre was really impressive.

I could see what Shawn meant. Normal stereo is fired into your ears, but this Dolby software converts it into a kind of sound halo around your head.

And the Dolby button on the Symbian phone screen took me right back to my first cassette recorder back in the 70s, which wiped out the awful hiss that came with it. These days however, the Dolby button means a whole new cinematic surround sound experience.

Nokia Siemens Networks

Leaving the Dolby people quietly entertaining themselves we headed off to
Nokia Siemens Networks  who, with Qualcomm, showed us a new feature that will allow people to benefit from two base stations at the same time when using their phone.

Called HSPA+ (High-Speed Packet Access) Multiflow it allows the transmission of two data streams from base stations in two adjacent cells to a single handset.

After being standardised later  this year, it should come into use commercially sometime next year on existing hardware. Only a software upgrade will be needed for networks, modems and smartphones. And the future benefit to phones like the Nokia Lumia 900 which will run on HSPA, is obvious.

Nokia Siemens demonstrated the effect using a commercial base station and prototype USB dongle from Qualcomm .

Nokia Siemens Networks also repeated their world 4G speed record yesterday with 1.4 Gigabits-per-second mobile call.

Other partners at the show included Microsoft, who were displaying Nokia Windows Phones, much as they did at CES.

They were also holding a Smoked by Windows Phone  challenge, where any Mobile World Congress visitor could try to outpace a Microsoft booth host who was using a Nokia Lumia 800 after nominating a task.

If you could manage to post a picture to Facebook before they did, for example, you’d win €100. It was fun watching users of so-called rival smartphones fumble and lose. Out of 20 or so challenges on the first day, they’d only paid out twice. And one of those was a dead heat, a Microsoft spokesperson told me.

It’s now a couple of weeks since the Nokia 808 PureView launched and the Internet is buzzing with fantastic feedback. Websites and blogs solely dedicated to cameras have given raving reviews about the image quality of this smartphone, and quite rightly so. The Nokia 808 PureView has a mind-blowingly good camera. One area, however, that our photography guru, Ari Partinen, believes hasn’t been discussed in enough detail is dynamic range. To put that right, he shares his thoughts today.

The benefits of super pixels

In very simplified terms the Nokia 808 PureView combines the information from roughly seven pixels and uses this info to re-create what we call super pixels. The benefit of doing this is that when you multiply several signals (or pixels in our case) with random noise floor, you end up with amplified signal, but lower noise floor compared to the actual image signal. The most obvious benefit from this is the improved signal-to-noise ratio in low light images, but also daylight images benefit from this as an increased dynamic range. And indeed the dynamic range of Nokia 808 PureView is huge and achieved without any additional HDR processing, which often may lead to unnatural results.

Taking photos in the midday sun

Let’s discuss the following image of this lovely lady, on a beach, in Cape Town South Africa. All photographers know how deadly the midday sun is when it comes to ruining your images. The shadows caused by that midday light are a problem for any camera currently on the market. This picture was captured around 11:00am in South Africa and as you can see from the image the light was already very harsh. But the Nokia 808 PureView did excellent job preserving all the details also in the shades, making the smiling eyes of our lady perfectly visible. And please remember, we are running the camera in standard mode, without any excess HDR processing.

Another maybe even more astonishing example is the second image.

This image was originally planned to be a funny image with just legs sticking out from underneath the colorful hut, but for our amazement we ended up seeing also the upper bodies of the two young fellows in the picture. This image was captured around midday in Cape Town, South Africa and from the shadows you can see that sun was practically straight up. Holding the details in those strong shadows would be an amazing job for any camera, let alone for a mobile phone or smartphone.

The easy way to achieve perfect exposure

Also very welcome feature for more serious photographers is the live histogram that makes achieving the perfect exposure very easy. Just adjust the exposure compensation so that the bright part of the histogram does not clip, and the massive dynamic range of the Nokia 808 PureView will preserve the details in the dark end. As you can see from the image below, the live histogram becomes visible automatically when exposure compensation is adjusted.

Digital camera markets are currently full of all kind of HDR cameras and applications to handle those very high contrast scenes but with Nokia 808 PureView we took another route. We actually designed and executed a camera that is simply so good, that no extra HDR processing is needed.

People have rightly focused on resolution, the details that the Nokia 808 PureView is able to capture and its great low light capabilities. Now, thanks to Ari, we hope you have a better idea of its massive dynamic range, too.

700-nokia-808-pureview-white-pairThat buzz you’ve been hearing isn’t a swarm of early spring bees. It’s the discussion about Nokia’s 808 PureView smart phone, the one with a 41-Mp sensor tucked inside.

That’s bigger than the 36.3 megapixels in the Nikon D800.

A week ago Damian Dinning, the head of imaging experience for Nokia smart devices, explained the concept in an article on the Nokia 808. He was there at the birth.

It isn’t about the megapixels, he argued, explaining “the innovation and news is not the number of pixels but rather how those pixels are used.”

HOW TO ZOOM

The team, Dinning said, was working on “imaging rich” phones that would include optical zoom. Mobile phone screen sizes were getting bigger and customers were demanding better image quality from their phones, factors which pushed the limits of optical zoom design.

The team nearly brought to market a device that used folded optics to zoom (like many ultracompact digicams) but scuttled the project due to the size of the camera module and its performance.

“It became clear to us that if we were ever to meet the increasing expectations and evolving market dynamics we were going to need to find a new direction in imaging,” Dinning said.

As the team developed different optical zoom modules, they ran into significant problems: “performance in low light; image sharpness at both ends of the zoom range; audible noise problems; slow zooming speed and lost focus when zooming during video.”

To use optical zoom, “you’d need to accept a bigger, more expensive device with poor f no., a small and noisy image sensor and lower optical resolution just to be able to zoom.” Not good.

OPTICAL OUT

Then came the key discovery, inspired by the company’s understanding of how to integrate large image sensors into small camera modules. The trick was to “use a sensor with somewhat higher resolution than needed at the time but output a lower resolution image than the sensor input resolution, possibly adding some upscaling/interpolation to provide a meaningful enough zoom range.”

In short, they abandoned the idea of using optical zoom in favor of, well, digital zoom.

Time out.

TWO KINDS OF DIGITAL ZOOM

In the camera world we inhabit, digital zoom is not held in very high regard. But there are two variants of the concept.

In the common variant, a crop of the sensor is upsampled to the same image dimensions as a non-digital zoom image would be. If, for example, you have a 2000×3000 sensor and take a 1000×1500-pixel crop in digital zoom mode (to zoom in on the scene), the camera would interpolate that back up to 2000×3000 so it would be the same size as all your other images.

As sensors became larger, however, the upsampling became optional. In this variant of digital zoom — often tagged Smart or Intelligent — the crop simply isn’t upsampled. So your 16-Mp camera takes 10-Mp or 5-Mp images when smart digital zoom is engaged. And that’s plenty good enough for prints up to 13×19.

But in the camera world, you’ll notice, all of the sensor pixels are normally used except when using digital zoom.

SMALL IS BEAUTIFUL

Nokia turned this approach on its head by establishing a 5-Mp image size for the 808 PureView and downsampling everything to it. A 5-Mp camera in a smart phone is still pretty cool. On a digicam, not so much.

Why would they downsample everything?

Downsampling “could create an output image with excellent low light performance, excellent optical performance as well as maintaining a low f no,” Dinning explained. “Instead of trade-offs, there would be significant benefits, especially at the wide range of the zoom. As an additional benefit the file sizes would be small due to low noise whilst the level of detail would be way beyond anything seen before thanks to the pixel oversampling.”

So by pixel binning — as some digicams do in low light Scene modes that save smaller image sizes — you gain some imaging chops. You can zoom. Noise is averaged out. And the file size is kept low enough to fire off to Flickr or FaceBook, etc.

There is an option to save the 41-Mp image in the 808 PureView (and zoom later in-camera), Dinning noted, but in typical use, you would be recording 5-Mp images.

 41-Mp image from the 808 PureView

Dave did a little math to explain the 41-Mp sensor size. “Zoom is linear, while pixels vary as an area or the square of the magnification. So 3x zoom = 9x the number of pixels. 3x wider and 3x taller: 41/9 = 4.56, so they’re actually pushing it slightly to come up with a full 5 megapixels.”

If Nokia were a camera company instead of a phone company, they would be marketing a 41-Mp camera featuring 3x smart digital zoom at a 5-Mp image size. But as a phone company, they’re selling a 5-Mp smart phone with 3x zoom and great low light performance.

Nokia has posted some Nokia808 PureView images on Flickr. Several image sizes are available for each image, including the 7728×4354 original and 1024×577 downsampled image. We printed a full resolution image on 13×19 Moab Slickrok Metallic Pearl and are pretty sure nobody is going to believe it came from a smart phone.

The company has also posted a white paper on its PureView imaging technology.

10 YEARS BACK

Allow me to take you back 10 years back in history of Nokia. In the second quarter of 2002, Nokia released Nokia 7650 smartphone. It was notable as the first Nokia with built-in camera. Even though it had only 0.3MP camera, this was a major improvement towards camera phones.

10 YEARS LATER
And now 10 years later Nokia shocked the world by releasing a massive 41MP Nokia 808 Pure View!!Yes that’s 41MP in a phone. This powerful phone with almost wall see-through, bird eye zoom function and very detailed imaging camera feature the Pure View Pro. An imaging technology that use the combination of a 1/1.2 large, very high resolution 41Mpix with high performance Carl Zeiss optics. The large sensor enables pixel oversampling, which means the combination of many pixels into one perfect pixel. Pure View imaging technology delivers high image quality, lossless zoom, and improved low light performance. This is the phone the universe is talking about!

HOW OTHER PHONE GIANTS WILL RESPOND
Nokia this time had taken the pixel fight to an unbelievable level. We find ourselves with more questions than answers about what other phone giants will respond.
Will other manufacturers decide to take Nokia head on and try to beat the 41Mpix record?
Will competitors decide not to challenge the 41Mpx and focus on other technical specifications?
Is it time for the Nokians to proudly take pictures in public and see owners of competitors phones hide their phones in shame?
Is Nokia satisfied with the amount of pixels in the Pure View or they have future plans to release even a more powerful camera phone?
Is it time for Nokia to give Samsung and Apple a run for their money by branching into the tablet industry?

Nokia N8 is widely accepted as the best camera phone with its 12-megapixel Carl Zeiss lens. Now Nokia has changed its flagship model by introducing Nokia 808 Pureview at MWC 2012, a smartphone with a whopping 41-megapixel camera system.

Nokia surprised the world by unveiling Nokia 808 Pureview, which is a big leap among camera phones, with its 41 megapixel camera (with Carl Zeiss Optic sensor). This has put Nokia ahead in the race as there is hardly any camera phone in the market that can capture better quality images than Pureview.

Pureview can capture photos at a resolution of 7728×5354 pixels in 16:9 format or 7152×5368 pixels in 4:3 format.

Nokia recommends 5-megapixels as the resolution to capture complete noiseless pictures. The camera uses the concept of oversampling to combine up to 7 pixels into one single pixel. As a result, a perfect picture is formed. By zooming the picture up to 3 times, there is no loss in quality or details.

Like us on Facebook

The maximum possible resolution is 38 megapixels with Creative Shooting mode. Nokia 808 Pureview records 1080p videos with 4X lossless zoom at 30 fps. Crisp clear audio recording takes place even at high level of 140 db.

Nokia Pureview has surprised us with its camera system but it is not amazing as other specs draw a yawn. The phone has 4-inch ClearBlack AMOLED screen with a resolution of 360×640 pixels. It has 1.3 GHz processor (single-core) and 512 MB of RAM. Pureview has 16 GB of internal storage memory which can further be extended with microSD card support.

The screen resolution is too low to view the amount of detail captured by the phone camera. Also, these days, dual-core phones are common even as quad-core phones are making their way into the market. In such a situation, single core processor is not of much consideration.

Lastly, Nokia 808 Pureview runs on Symbian Belle OS, which does not have such good apps availability as found in Android or iOS platform.

At MWC, Nokia announced that the 808 PureView wouldn’t be coming to Sweden officially, alone among other Euro countries. Following something of a power user outcry, Nokia Sweden has announced that the 808 will be sold in Sweden after all. PR quote below…

From the Nokia Sweden article :

Following the fantastic response after the launch of the Nokia 808 Pure View from Swedish operators, retailers and consumers, we are now pleased to announce that the Nokia 808 Pure View will be sold in Sweden. We’ll be back with information on price, availability and dates shortly. But we can now confirm that this unique camera phone with 41 megapixel camera and Carl Zeiss optics, will go on sale in Sweden, in contrast to what was communicated at Mobile World Congress.

Although Sweden wasn’t the only country to not ‘get’ the 808 originally (the USA springs to mind!), it’s still an important European market and it’s good to see the marketing about-turn and good communication from Nokia Sweden.

Nokia imaging expert Damian Dinning on the journey to create industry-changing camera tech .

Published by Damian Dinning on March 7, 2012 .

Nokia-808-PureView-and-BH-221-group

 GLOBAL – Yes, the Nokia 808 PureView has the largest-ever sensor by a long way shoe-horned into its pocketable dimensions. When people hear the figures, many either find their jaws on the floor in sheer astonishment or struggle to believe it’s possible. After all, this isn’t a digital SLR (that would be astonishing enough) but a smartphone! Something you can carry with you at all times.

I can understand the reactions: even people inside Nokia have reacted similarly.

Despite this, the innovation and news is NOT the number of pixels but rather HOW those pixels are used.

It’s been incredibly exciting to have been associated with this project from a very early stage. For some of our team, it’s taken over five years to bring this to the market, such is the technological and engineering achievement, so you can perhaps imagine the excitement but also sense of relief some of us are feeling right now.

Given the amount of effort that’s gone into this project, I wanted to share more of the background as well as some more detail around how PureView works. 

PureView - nets

Where it all started

In late 2005, Nokia were in the final phases of preparing the Nokia N73 3Mpix AF and the rather unique N93 3Mpix AF 3x optical zoom smartphones for introduction in the spring of 2006. We’d already been researching alternative directions in the area of imaging and camera development as well as extending the direction both of these products would be soon starting. Roughly a year after their introduction, the N95 and N93i came to market.

Around this time, we were starting the development of a number of next-generation imaging rich smartphones. Commercial products such as the Nokia N82, N86 8MP as well as the extremely popular Nokia N8. But there were many other projects intended to include optical zoom which never made it to the market. A number of these were quite advanced concepts using different camera configurations and physical form factors, some conventional, some significantly different.

PureView - SA shoot

However, over this time, the market was evolving. For example, displays were becoming bigger and bigger. This aspect alone resulted in a number of concepts not being taken forward due to the limited potential screen size of some concepts. Another important factor was how market expectations were evolving in the area of image quality.

For example, at one stage we had working prototypes equipped with optical zoom using folded optics. Despite this almost reaching commercialization, the module was relatively large and we decided the performance would not be fundamentally good enough to meet the evolving expectations.

It became clear to us that if we were ever to meet the increasing expectations and evolving market dynamics we were going to need to find a new direction in imaging.

After developing several optical zoom modules, we were still seeing significant performance trade-offs caused by optical zoom: performance in low light; image sharpness at both ends of the zoom range; audible noise problems; slow zooming speed and lost focus when zooming during video. We became convinced this could never be the great experience we once hoped. You’d need to accept a bigger, more expensive device with poor f no., a small and noisy image sensor and lower optical resolution just to be able to zoom.

PureView - rocks close up

Around this time, the Nokia imaging team had just finished creating a tool called the Camera Simulation Environment. This tool is a virtual environment where we can easily simulate the performance of different types of optics, image sensors and image processing algorithms and see the impact of different technical solutions to the final image quality. It’s an easy and fast way to try new ideas.

Nokia was also leading the market by driving large image sensors into devices and understood how to integrate large image sensors in to small camera modules. The Nokia N73 and N95 were the first mobile products with 1/2.5” sensors and since then we’ve continued to introduce large sensors such as the 1/1.83” sensor in the Nokia N8.

Of course, we understood the need for being able to zoom and frame the shot during video recording. However, compromising image and video quality to achieve the zooming capability was something we were not willing to do.

PureView in low light

One idea leads to another

One day when a couple of our engineers met over lunch, one of them mentioned how earlier that day he found an article in the Electronics Times on satellite imaging inspiring, specifically how satellite imaging uses extremely high resolution sensors to capture high resolution images.  It was the fact that we typically only ever look at a section of a satellite image that inspired him the most.

An idea emerged from this discussion to use a sensor with somewhat higher resolution sensor than needed at the time but output a lower resolution image than the sensor input resolution possibly adding some upscaling/interpolation to provide a meaningful enough zoom range. This would provide the user with an experience similar to optical zoom. Whilst the performance was thought to be superior to conventional digital zoom as well as result in a far smaller package than optical zoom, it was felt that the performance would still not be up to the standard we were aiming to achieve.

Sometime later after a ten-hour long meeting seeking to solve the technical challenges of optical zooming, a few engineers were sitting in a Tokyo hotel bar. During a lively discussion about how the technical problems of optical zooming could be solved the earlier idea came up again in conversation…. What if we would just add enough pixels to avoid having to upscale the image?

….after some further discussion they concluded that a sufficiently large enough image sensor could create an output image with excellent low light performance, excellent optical performance as well as maintaining a low f no. Instead of trade-offs, there would be significant benefits, especially at the wide range of the zoom. As an additional benefit the file sizes would be small due to low noise whilst the level of detail would be way beyond anything seen before thanks to the pixel oversampling.

PureView - hanging

At full zoom, while pixel oversampling could not be used, optical performance would benefit as only the central optical path would be used, where the performance is always superior due to manufacturing tolerances and light incoming angle. We could therefore keep the same low f no. and achieve performance which is not possible with optical zooming (not even in expensive SLR optics. As a bonus the closest focus distance would remain the same as wide, resulting in greater macro performance!

We would also achieve instant and silent zooming by keeping the focus during zooming which has always been a problem in optical zooms. We would also be able to achieve simpler, smaller and more robust construction for the camera. Eureka! The solution was right there!

That evening the basic idea had been sketched on a bar napkin, but even during ‘the morning after’ it was clear this idea was really worth taking seriously.

PureView - hanging wider

In order to make the camera happen, the largest and highest resolution image sensor in mobile devices would need to be created. Simulations showed that we would need new solutions and materials in the optics to be able to achieve great optical performance in a small enough package. Manufacturing tolerances, materials and surface accuracy used in SLRs, pocket cameras or mobile cameras would not be enough to make it work. Working closely with Carl Zeiss, we analysed different optical solutions, materials and manufacturing technologies, searching the world for image sensor technologies and companies willing to take on the challenge.

We had often debated that, for the vast majority, 5-megapixels completely fulfils their real world needs, but the market for many years has been pixels, pixels, pixels. It’s hard to block that out. Our friends at Carl Zeiss believed the same. At the time, the challenge was like Columbus trying to convince people the world was round and not flat.

Shaping the sensor

At this time, the sensor was supporting the conventional 4:3 aspect ratio. 4:3 aspect ratios were the norm but we could see the future was 16:9. The challenge was how to support 4:3 and16:9. This part of the story I remember well as I was in the meeting when we brainstormed this part of the module design.

People from Nokia were in the meeting, of course, but also our friends from the companies we work with often on our high-end optics and sensors. The atmosphere was relaxed but I had a feeling that some of our optics and sensor suppliers thought we were perhaps crazy. Nevertheless, they were still putting 100% into the project. We were really pushing the boundaries of optical design at this point clearly going where no one had dared before.

In this meeting we created the idea to use the 13:9 sensor based around the optical circle to fully support both 16:9 and 4:3. Of course, since then we have been incorporating this into the new modules for example in the N9, Lumia 800 and 900. But to maintain the same effective zoom range someone quickly pointed out we were going to have to increase the size of the sensor even further… and that’s how we ended up with 41-megapixels.

PureView - ultimate zoom

A few months later, in October 2008, the initial prototyping had been done. There was enough evidence now to show this was possible, although we knew there were going to be lots of challenges ahead of us.

Many different optical designs were trialled, using different lens configurations, lens materials, lens designs etc. In the end, I think we considered around 40 design proposals. As one aspect improved, another became worse. We continuously changed and then evolved the design until we were completely happy with the balance of the various aspects.

But even then, while we knew the camera performance would be really good, we didn’t know how good. Simulations are one thing but with so much complexity involved in the image processing as the area of the sensor used changed and effecting scaling and oversampling behaviour, we never really knew that we could be 100% confident what would work well and what wouldn’t. A great deal of discussion and simulating was carried out to try and predict every eventuality, but there’s only so much you can do.

When the very first prototype camera modules became available, the excitement and anticipation of all those involved in the project was pretty extreme. Would it be as good as our simulations showed? One sample was sent to our friends at Carl Zeiss for testing around this time. A few of guys from our imaging team went to take some shots over the Pyhäjärvi lake, which lies in between cities Tampere and Nokia (yes, there really is a city called Nokia in Finland).

I remember the content of two emails still to this day. One from the Tampere team with images attached captured with the first prototype camera and another captured with a Canon digital SLR as a reference. I opened both images and viewed immediately at 100%. Initially, I thought the images were labelled wrongly. Then I also saw the email from Carl Zeiss with the results from the lab testing. It’s usual for Carl Zeiss to provide a list of comments on areas where improvements could be made. On this occasion however, the email was uncharacteristically short. Here’s a short unedited excerpt from that email: “Our lab people are VERY happy with the quality. :-) ”

Relief!

This is, without doubt, our most complex imaging project to date. Often the ‘big idea’ has involved much discussion, but throughout the development process, as exciting as it may sound to introduce a device equipped with a 41-megapixel image sensor, our real excitement has ALWAYS been associated with the opportunities and in particular the performance this provides in its default form when shooting ‘just’ 5-megapixel images or when recording full HD video. We’ve waited a very long time to be able to do what we believe is right and break free from the years of legacies laid down behind us.

During the journey, what was originally a simple idea evolved into something a great deal more revolutionary. This was possible due to Nokia’s long expertise in imaging, partnering with the best companies in the world, incredible craftsmanship and unwillingness to compromise in performance.

Nokia’s Pureview 808 smartphone has a 41 million pixel camera

Nikon has claimed that it’s not worried by the new Nokia 808 Pureview smartphone, which features a 41 million pixel camera and Carl Zeiss lens, instead claiming that it is still growing in a shrinking market.

Speaking to TechRadar, Jeremy Gilbert, UK marketing manager for Nikon UK, said “As long as people come into photography, then that’s all that matters.

“We’re not thinking too hard about it, if we started worrying what the mobile phone industry was doing then that would complicate matters.”

Last year, the Nikon Coolpix S3100 was the best-selling compact camera in Europe, while earlier in the year James Loader, product manager for Coolpix claimed that Nikon had yet to feel the bite from the rise of smartphones .

Decline

The news comes after it was revealed that compact camera sales were down 30% in 2011, when compared with 2010.

“We’re still growing in a declining market,” Gilbert said, “We’re still building our proportion of the market.”

Gilbert also said that Nikon was the top-seller of compact cameras during February 2012, knocking the previous leader, Fuji, off the top spot.

“Our L series [Nikon’s budget range] is doing extremely well, and we have worked hard to get a much broader variety of cameras in supermarkets to increase distribution.”

He joked that he’d like to see a head-to-head between the Nokia Pureview cameraphone and one of Nikon’s compacts.

We’ll be keen to put the phone up against traditional cameras when it becomes available for testing, watch this space.

A: The optics and lenses are co-developed by Nokia and Carl Zeiss, but not the sensor.

Q12 : How much more light does this oversampling get you compared to 41 mpx? How do these figures compare to the N8?

A: We don’t have final figures there yet, this is an area we are still working on. Currently the difference is significant. In daylight with full wide-angle/maximum oversampling there is no visual noise in 5mp images, yet the detail is far higher than previous devices.

Q13 : Would the user of the Nokia 808 still be able to make full use the video and picture editing build-in software from Symbian S3?

A: Absolutely! There’s never been a better opportunity to these editing tools. We actually have some improvements to the editing software on the Nokia 808 PureView, with a simplified video editor and an enhanced still image editor. You can also crop images directly in the full screen gallery view.

Q14 : Was there any specific reason Pure View was launched on Symbian over WP7?          

A: We’ve heard this question many times! This is a great example of how we’re still investing in Symbian by bringing innovation on top of that platform. But as we’ve said, you will see PureView technologies coming to future products as well.

Q15 : What is the aperture of the 808 PureView?

A: f/2.4

Q16 : The Pure View teaser was a video. So, is the 808 a video-centric device rather than for photography?

A: The Nokia 808 has been designed for the full video/imaging experience -(including audio!)

Q17 : What is the name of the GPU chip?

A: We typically don’t disclose who our suppliers are of various components. What we can say though is that Nokia was one of the co-developers of the companion chip

Q18 : Will this chip be used by any other manufacturers, or did you guys develop it exclusively with your supplier for the 808?

A: The sensor was co-developed by Nokia, it’s exclusive to Nokia. Definitely not an off the shelf component! ;)

Q19 : Is it possible to get RAW pictures with the 808 PureView?

A: No raw support, but it is possible to capture the full resolution images which correspond to the aspect ratio in use. You can also select a higher quality JPEG setting.

Q20 : Will the 808 have manual exposure controls and auto exposure lock at half-press?

A: Yes!

Q21 : Many have lamented the lack of lens protection (ala N82, N95, N900), etc. Are the days of a lens cover gone as a design element?

A: We actually announced a hard cover accessory with lens cap for the Nokia 808 PureView atMWC12, for users who value this.

Q22 : What’s the HDMI output of the Nokia 808 PureView?

A: HDMI output is 1080p

Q23 : Is this technology similar to the Lytro cameras?

A: No, it’s not similar. But Lytro is another great example of how you can bring great innovation to imaging. Nokia PureView technologies are unique to Nokia.

Q24 : What kind of capture delay is there based on the higher image size? Also is it possible to burst capture and what is the maximum burst speed?

A: You can capture continuously by holding the capture key, there’s no dedicated burst mode. Shot to shot in full resolution is similar to N8

Q25 : What is the shutter lag time on the 808 PureView?

A: The shutter lag is now just 0.09 seconds.

Q26 : How much will the 808 PureView retail at?

A: The expected consumer price for the Nokia 808 PureView is EUR 450 before taxes and subsidies.

Q27 : Will HDR imagery be incorporated in the 808?

A: We have provided exposure bracketing for the first time, we believe this will provide greater flexibility for use with PC editors which specialise in HDR. The delay in full resolution mode is roughly the same as the Nokia N8. There is no dedicated burst mode, but you can do continuous shooting by holding the shutter down. We’ve also included histogram for the first time :)

Q28 : Does the exposure bracketing support 5 as well as the default 3 image cluster? Also, what is the time between capture for each image as this impacts on fuse quality?

A: 3 and 5 frames with increment control of 0.3, 0.7, 1.0 and 2.0 EV

Q29 : How many metering modes are there?

A: Just the one.

Q30 : Is there any significance in 41MP as oppose to 40MP, or 50MP?

A: 41MP is what we needed to provide optimised 16:9 and 4:3 plus the zoom range we wanted to provide.
