One of the most notable innovation in mobile imaging is the Pureview Technology. Originally developed by Nokia and Zeiss back in 2012 (and later by Microsoft Mobile), Pureview features a dedicated on-chip image processor that performs image scaling with oversampling to achieve a lossless digital zoom. The first smartphone to use the technology is the Nokia 808 PureView, which features a whooping 41MP sensor. While it sounds gimmicky, the large megapixel count is actually necessary for the smartphone to achieve a digital zoom without compromising the overall image quality. PureView continues with the Lumia line-up even after Nokia sold its mobile division to Microsoft in 2011.
