Best Mobile Phone Nokia 808 PureView in 2012


Nokia 808 PureView is a Nokia Belle smartphone, first came out on 27 February 2012 at the Mobile World Congress. It is the first smartphone to feature Nokia's PureView technology, full resolution pictures, higher definition and light sensitivity, and enables lossless zoom.
It features a 41 megapixel 1.2 sensor and a high resolution 2.4 Zeiss all-aspherical 1-group lens. The 808's sensor was the largest and highest resolution sensor in a cameraphone at the time of its launch, a record previously held by Nokia's N8, sporting a sensor 2.5 times larger than that of its predecessor.
The 808 won the award for "Best New Mobile Handset, Device or Tablet" at Mobile World Congress 2012, and the award for Best Imaging Innovation for 2012 from the Technical Image Press Association.

Nokia 808 Pro camera,;
PureView Pro is an imaging technology used in the Nokia 808 PureView device. It is the combination of a 1.2 large,very high resolution 41Mpix image sensor with high performance Carl Zeiss optics. PureView imaging technology delivers high image quality, lossless zoom, and improved low light performance. It dispenses with the usual scaling/interpolation model of digital zoom used in virtually all smartphones, as well as optical zoom used in most digital cameras. In both video and stills, this technique provides greater zoom levels as the output picture size reduces, enabling 4x zoom in full HD 1080p video, 6x lossless zoom for 720p HD, and 12x zoom for nHD video.
