PureView imaging technology.

Lessons learned

With the 12Mpix Nokia N8, for example, we were more concerned with capturing photons of light than

ramping up the number of megapixels. We bucked the trend and went with a large sensor and 1.75

micron pixels — but the result was a new benchmark in image and video quality. This set the Nokia N8

apart at the time, and competitors are still trying to match it two years later. The Nokia PureView Pro

comes is equipped with an even larger sensor, 1/1.2” approximately 2.5 larger than the sensor used

in the Nokia N8. The result is an even larger area to collect photons of light. With PureView we’re

continuing to make choices focused on performance rather than pixels for pixels’ sake. Fewer but

better pixels can provide not just better image and video quality, but better overall user experience

and system capability.

In fact, 5Mpix-6Mpix is more than enough for viewing images on PC, TV, online or smartphones.

After all, how often do we print images bigger than even A4?

Why the megapixel xation?

It all stems from the very early days of digital cameras, when image quality was aected by the limited

number of pixels available. As the pixel numbers increased, image quality dramatically improved.

However, once the resolution reached around 5Mpix-6Mpix, the real-world benets became debatable.

But by then, the market had made a direct correlation between number of pixels and quality of image.

The more pixels the better, was the received wisdom. And this thinking has stuck. Though today

manufacturers would happily reduce the number of pixels in their cameras, and instead concentrate on

their lenses and sensors, they’re not so sure the market would accept this.

But let’s consider why you might need more than 5Mpix. The most popular argument we hear is the

versatility the extra pixels provide. Specically the ability to crop images or create large prints.

Cropping

With the Nokia 808 PureView, you can frame your shots on the spot. However, if you prefer, you can

defer framing until later, as there is a user setting in the Creative Shooting Mode for capturing

‘full-resolution’ images. You can choose to zoom into any part of the image, and nd new creative

views in the original.

Actually, we thought people might want to do both, so we decided to make it as easy as possible to

switch. We hope this will open up greater creativity in composition — you can shoot quickly and crop

later when you have more time and a larger display to work with. You can re-frame as many times as you

like, scale the image to your preferred output resolution, and choose the relevant downscaling method

depending on what you want to do with it.
