The PureView Pro technology consists of:
- A super high-resolution 41 MP sensor
- Pixel oversampling technology
- Carl Zeiss™ lens optics.
The large sensor is used for oversampling pixels to create great image quality and amazing low light performance, but it can also be used for lossless zooming. Oversampling means that many pixels are combined into one superior pixel.
For more detailed info on the relationship of the zoom and oversampling, see the Nokia 808 PureView white paper.
