What is Nokia PureView Pro Technology | Facts About 41MP Camera Phone
Smartphones in market today comes with 5MP or at most 8MP Camera. Some more exaggerated came prepared to capture images up to 12 MP. But can you imagine a phone with 41 MP sensor? Nokia imagined and created a smartphone to beat all expectations.
The Finnish manufacturer released a video about the extended development of the technology used in Nokia 808 PureView camera model which can capture images at 7728×5368 pixels – approximately 41 million pixels. It is the first to have PureView Pro technology, which ensures the use of zoom without loss in quality.

Quality is better than Quantity
You are probably surprised by the ability of this camera. Well, 41 Megapixels is a number that surprising. However, according to whitepaper released by Nokia, this value is not so important, because the company stands for quality, i.e, PureView Pro technology is not only able to work with a lot of pixels, but the ‘big deal’ is how intelligently they’re used.
A revolution in Photography
Imaging technology PureView Pro eliminates the use of techniques such as interpolation and scaling to make the approximation of the image – features commonly used in other smartphones. It also overcomes the traditional technology used in cameras, avoiding the lens position adjustment and change in sensor sensitivity.
Thanks to high-quality sensor, the camera of the Nokia 808 PureView can offer a 3x zoom for still images with 5 MP and up to 4x while recording Full HD videos. If you want to capture clips at 720p, could bring the image up to 6x. To lower resolution (640×360 pixels), the approximation level reaches 12x.
How Carls Zeiss lenses achieve this without the resources used in other devices? The secret is in the high-resolution sensor. The zoom is not based on scaling up from a low resolution, however, is accomplished by selecting a particular area – like a cut of the field captured by the lenses.
As disclosed in an official document from Nokia, the zoom is determined by configuration. With 5 MP quality, for example, so that the sensor area to achieve 3072×1728 pixels, maximum zoom is reached and the camera prevents you “close” over the image. Inset: zoom is quiet, ideal for use during video capture.
More depth, more details
Zooming in or near a mobile part of the image later generate the same results. Speaking thus, the zoom may seem false, however, it serves to save work (since you do not need to crop the photo) and higher quality, after all, does not shake the image and the pixels are not biased.
Incidentally, the second document from Nokia, when the zoom is used, samples from multiple pixels are combined to form “superpixels.” When this happens, the level of detail remains intact, but the noise of the image are almost completely eliminated.
It is worth noting that the combination of multiple pixels is also used in no image zoom, and the level of combination is even greater and quality guarantee even higher. Importantly, it is not necessary to do any configuration for this feature to be enabled, because it is a basic component of PureView Pro technology.
Mobile phone for anyone who loves Photography
Due to the high quality camera, the design of the Nokia 808 PureView flees to the standards of beauty in ultrathin, however, as the manufacturer says, the camera (sensor and lens) of the device is 50% smaller than other conventional optical zoom. For the record, the phone is 1.4 inches thick and weighs 169 grams.
The hardware configurations are not the best, and the processor is a single-core 1.3 GHz He has 512 MB of RAM and 16 GB of internal storage. The operating system is Nokia OS Belle, the latest version of Symbian. With these specifications, the device is not suitable for games, however, is ideal for capturing images.
