Sharif Sakr talks about the Nokia 808 PureView Smartphone:
Now that Carl Zeiss-lensed camera: it handles continuous-focus 1080p, but is claimed to have an incredible sensor resolution of over 41-megapixels when shooting stills — or 34-megapixels for 16:9 images. It uses some clever interpolation jiggery-pokery that condenses four or five pixels into one pixel, to produce a smaller file size for the output image.
Like maybe to 3 or 4 images on the phone? How many pictures can the phone fit? Clearly for camera people… but would they really buy the phone? Why not just have a Nikon D series camera?
