The raw pixels are used to create a sharper, "normal" resolution image using a proprietary processing algorithm.

- the output is not 41MP

- the sensor is HUGE, so it's not just an excercise in shrinking pixels

- the lens is very high quality (and F2.4), not your average phone lens

- it has a separate processor for images

- Microsoft has tight hardware specs on WinPho, so it cannot used with specialized hardware like this
