Nokia 808 PureView.
Introduction
Nokia has created a stir as it introduced the Nokia 808 PureView at the Mobile World Congress (MWC) 2012, since the Nokia 808 PureView is a camera phone equipped with a 41-megapixel sensor. More interestingly, the Nokia 808 PureView’s sensor doesn’t only offer a significantly higher resolution than ever offered by any camera phone’s sensor, but it also comes in a larger physical size. It is also worth noting that the Nokia 808 PureView’s sensor is even larger than the sensors found on the majority of point-and-shoot digital cameras available on the market today.
Speaking of sensor size, the Nokia 808 PureView’s 1/1.2″ sensor is two and a half times larger than the one used by the 12-megapixel Nokia N8, which was the company’s top of the line camera phone in terms of imaging capability. For comparison, the Apple iPhone 4S only features a 1/3.2″ sensor, while most point-and-shoot digital cameras available today use 1/2.3″ sensors. Based on those facts, the Nokia 808 PureView is undoubtedly the camera phone with the largest sensor in today’s mobile imaging market.
The Nokia 808 PureView is available in three different colors.
Logically, packing a two and a half times larger sensor with more than three times the amount of pixel will result in a smaller pixel size, and a smaller pixel size generally decreases the image quality because it collects less light. Nokia is clearly aware of that and therefore implements a so-called pixel-binning process that combines seven pixels into a single super pixel. In other words, instead of trying to produce a large-sized image, the Nokia 808 PureView oversamples an image through the pixel- binning process in order to generate a smaller-sized but higher-quality image.
The pixel-binning process also explains why the Nokia 808 PureView will only deliver 3.5-megapixel or 8-megapixel still images in most shooting modes, although there is still a special shooting mode available for those who expect 36-megapixel or 38-megapixels outputs.
