If you thought camera sizes were getting grazy on smartphones, Nokia just decided to prove you right! What else could they be thinking of when announcing the new Nokia 808 PureView with its 41MP image sensor?
Before you start thinking about how fast your precious gigabytes would be gobbled up by 41MP snapshots, Nokia has taken care of that for you... Because this 41MP image sensor will actually provide you with more manageable 5MP photos. Yes, you're reading it right.
All those pixels will be used to enhance your photo, but each block of 3x3 pixels will end up accounting for just 1 single "noise-free" pixel.
Why should they choose to go insane with 41MP instead of a 5MP sensor with bigger pixels?... I can only think of the advantages of bypassing potential bad pixels (nearly every CMOS image sensor has bad pixels, that are auto-corrected based on its neighboring pixels). If you have one bad big pixel, you're losing a lot of detail, whether if you have 1 or 2 or even 3 in a block of 3x3 pixels... you'll still have enough pixels left to provide a more accurate result.
Unfortunately, as Android is not an option for Nokia, and instead of using Windows Phone, this Nokia 808 PureView relies on Symbian Belle, which might not be up to the task for anyone wanting a "41MP" camera these days.
