PureView

Alam niyo ba? Ang cellphone na ito ay may 41 Megapixel Camera. Oo tama ka, 41 Megapixel. Tapos pang lowlight photography pa siya. Ang features niya eh pang 24-70mm f-2.8. How amazing is that? Sa Cellphone lang ha? Grabe na ang teknolohiya ngayon. Breakthrough talaga. Nakaka elibs lang eh.

Pero kung may DSLR ka na, sa tingin mo ba bibili ka pa ng ganitong cellphone? Edi LENS ka na lang hindi ba? Pero nakakatuwa at may ganitong gadget na parang may dala ka na ring DSLR at the same time cellphone.

Tindi!

Ang unit na ito ay Nokia 808 PureView Camera.

Ito ang iba sa features niya

  • Belle OS,
  • 4-inch display
  • 41 Megapixel Camera
  • 24-70mm f-2.8

Hindi pa alam kung ano ang presyo. Basta sa May 2012 daw ito ilalabas.

41 MP smartphone camera!!!

This is true. New Nokia 808 Pureview has really 41 MP sensor, not some artificial “oversampling” knock-off marketing trick. But, instead of producing billboard-ready huge files, Nokia produces smaller 5 MP images. It picks 7 pixel subsets, votes noise out of equasion and produces clear noiseless images. This is in theory. I haven’t seen low-light samples yet.

I was really surprised how huge the 1/1,2" sensor is. Almost same size as found in new Nikon hybrid mirrorless system camera.

Seeing sample images I strongly agree, that this phone is the best cameraphone in the world. We used to say it about Nokia many times earlier, but this quantum leap turns heads.

I did some calculations and found that 41 MP is not extraordinary density. Nikon Coolpix L26 with it’s 16 MP sensor has actually pretty same pixel density, due to smaller sensor. Both have approx 500 - 600 thousand pixels per square millimeter. Current hybrid cameras have 30-70 thousand pixels per square mm and flagsip Nikon only 19 thousand pixels. Less pixels per square mm means bigger pixels and more light (more fotons) per exposure. That means better ISO and less noise.

Nokia has pretty advanced noise reduction system, based on pixel subset averaging (or may be voting) mechanism. I am eager to test the viability of that algorithm.

Why Nokia used such sensor?

  • probably because of marketing, yes, 41 MP makes buzz;
  • because of non-mechanical zoom.

We’ll see… (Chinese saying).
