Nokia 808 PureView

[h=2]Explained: Nokia's latest smartphone outguns the Nikon 36Mp D800[/h]A pixel count of 41 million in a smartphone like the Nokia 808 PureView may seem more than a little excessive, but Nokia claims it will mean less noise, not more. While cramming more pixels onto the sensor in theory enables a camera to record more detail and allow larger prints to be made, there is also usually a downside in the form of more image noise.

[h=2]Trying out the first 41MP smartphone[/h]The Nokia 808 Pureview wasn't meant to be a surprise, but with a 41MP camera and 1080p video recording, it certainly seems to have turned out that way.
The phone is running Symbian Belle, and will probably be one of, if not the, last top end Symbian device to hit the market before all the cool technology gets chucked into Windows Phone.

Oh that looks awesome. But what about the memory the images take.

we are talking about 15MB average per picture. you are not really going to take 41mp photos. you are going to use the 41mp sensor to take photos in the range of 8-12 megapixels.

On the other hand, Nokia has made, judging from specs and early samples alone, one of the best smartphone cameras on the market. For one thing, the 808 PureView is actually, by default, a 5MP camera. If the camera is making images with just 5MP, though, why bother with the huge 41MP sensor?

The answer is oversampling. At its default 5MP setting, every pixel in the finished image corresponds to about eight pixels on the sensor. This oversampling helps reduce noise, increase color accuracy, and increase sharpness.

Oh ok... But why 41MP then, if you are taking only 8 - 12 MP images.
Did anyone, anywhere, see a 41MP photo?

read the article above. it sort of interlaces/samples the pixels together for much less noise and much more clarity.

and it you want to see a high res image:

Thanks...Yeah, i understood a bit about the technique they use, so as they say it would be a good 5MP camera as far as clarity/noise is concerned.

And for that Paris Virtual tour. It's very high quality, i wander how they capture that panoramic image (GigaPixel). Another thing, i never knew houses in Paris still have Chimneys(orange)!

they have stitched together thousands of images.and to be honest, no one usually needs a photo above 8MP in most scenarios. So I'd rather have a good quality 8MP pic than a blurry 20MP one.
