Nokia 808 PureView

Nokia's 808 PureView smart phone, with a 41-Mp sensor, produces 5-Mb images

• the innovation and news is not the number of pixels but rather how those pixels are used (as 3x zoom and great low light performance)
• use a sensor with somewhat higher resolution than needed at the time but output a lower resolution image than the sensor input resolution, possibly adding some upscaling/interpolation to provide a meaningful enough zoom range
