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 was released on 26, July 2013. It contains Nokia's PureView technology, a pixel oversampling (a data binning technique) 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-inch BSI sensor with optical image stabilization (OIS), and a high resolution f/2.2 all-aspherical 1-group Carl Zeiss lens. Its front camera is 1.3 MP. In January 2014, Nokia released the ‘Black’ firmware update for the Lumia 1020, adding various new features, including improved image processing and support for RAW (DNG) files.
