PureView started under the Nokia branding and later became used under Microsoft Mobile. It is a camera technology that carries a high megapixel image sensor and combines it with on-chip image processors. PureView also uses optical image stabilization (OIS) to reduce image blurring in low light and high-end flashes ranging from triple LEDs to traditional Xenon. Finally, Zeiss optics are used for the lens elements, which range around 6 per camera.
The PureView cameras provide amazing results when compared to the competition. You can find Pureview cameras on the Nokia 808, Nokia Lumia 830, Nokia Lumia 1020, Nokia Lumia icon, Lumia 930, Lumia 1520, Lumia 950 and Lumia 950 XL.
We've taken a look at samples from various PureView cameras, and the results are generally rather spectacular. You can check out some samples from the Lumia 1020 here.
