NOKIA LUMIA 1020
The Nokia Lumia 1020 is a Windows Phone 8 smartphone developed by Nokia, first unveiled on 11 July 2013 at a Nokia event at New York. It contains Nokia's PureView technology, a pixel oversampling (a data binningtechnique) that reduces an image taken at full resolution into a lower resolution picture, thus achieving higher definition and light sensitivity, and enables lossless zoom. It improves on Nokia's previous versions of PureView by coupling a new 41 megapixel 2/3" BSI sensor with optical image stabilization (OIS), and a high resolution f/2.2 all-aspherical 1-group Carl Zeiss lens.
PureView Pro is an imaging technology used in the Nokia 1020 device. It is the combination of a 1/1.5" large, very high resolution 41 mpx image sensor with high performance Carl Zeiss optics. The large sensor enables pixel oversampling, which means the combination of many sensor pixels into one image pixel. PureView imaging technology delivers high image quality, lossless zoom, and improved low light performance (see below). 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, where a series of lens elements moves back and forth to vary the magnification and field of view. In both video and stills, this technique provides greater zoom levels as the output picture size reduces, enabling 4x lossless zoom in full HD 1080p video, 6x lossless zoom for 720p HD. Optical image stabilization is also present to nullify shaking of hands when taking a photo and to allow significantly more light to enter the sensor for better low light photos. It also has a shutter speed of 1/16,000 s
