Re: What is an Ultrapixel?

As far as I can tell it is a 2 um pixel in 4Mpix 1/3" format F/2, compared to 1.4 um pixel in 8 Mpixel 1/3" format which is what you will find in the iPhone and Samsung phones.

So, it gets twice the light or more, and sqrt2 improvement in SNR, assuming it is as efficient etc as the 1.4 um pixels.

It is quite a risk, as HTC says, to buck the trend.  I can't say it is a great move considering binning and other things you can do with more pixels and low read noise, at least in theory.    At least it is product differentiation and good luck to them on their grand experiment.  Hard to say who the sensor supplier is but I guess there are no supply issues, heh.

They should have called it the pen-ultra-pixel.  When you are #2 (in sensor tech) you try harder.
