Image quality is not about mega pixels. The 1020 uses silicon and software to compensate for the physical limitations of a short focal length and small aperture. Instead, a huge sensor captures many more pixels than you need, and then software algorithms distil this down to a five-megapixel image of great richness and detail. The sensor is 41 megapixels, creating as a first step a 34 megapixel image; the other pixels being put to good use interpolating the image. For a technical explanation, see [1]. The phone actually keeps a master copy of the image at full resolution, and presents the five-megapixel image to you right away for editing and sharing.
