We explain the mechanics behind the 41-megapixel camera on the Nokia 808 PureView

Generally speaking, larger sensors with larger photosites produce better looking images with less image noise and higher dynamic range. This is not always true, but if nothing else changes, increasing the number of photosites while keeping the sensor size the same tends to introduce more image noise and reduce dynamic range. The 808 PureView has a remarkably large sensor, as you can see in the comparison above. Not only is it significantly larger than image sensors used in most mobile phones, it's also larger than most digital compact cameras'. The worry then, isn't that the 808 PureView's sensor isn't large enough, it's that packing too many megapixels into a sensor of this size might adversely affect image quality.
