Nokia today released the 808 PureView of the 41 million pixel mobile phone , that will open a new era of smart phone image. The foreign media followed by the author, and uncover the mystery of the Nokia the 808 PureView R & D team, said that this innovative product is the result of five years of sword.
Easily can be a decent zoom lens is placed in the camera phone, Nokia might never made the biggest breakthrough in recent years. The technology is used on the 808 PureView Nokia engineers to break the routine, a typical example of courage to innovate, in accordance with conventional optical zoom lens in a small space like a cell phone can not display does not open the hands and feet.
Nokia imaging technology department heads juha Arak HU (Juha Alakarhu), in an interview last week, said: "We have long engaged in study of the optical zoom performance make it very clear on your smartphone into full play how difficult their structures are very complex, very difficult to manufacture. "
Arak Hu also said that this lens will be zoomed in a small amount of light spilled into, which means they can not play to the advantage of the optical zoom in the night, the definition will also be affected. Late one night, Arak Hu Elohim Saar Merlin, Eero Salmelin and other colleagues think of a solution. If large enough sensors can be placed in the smart phone, the camera will be able to digitally zoom in to eliminate the extra pixels.
Arak nonsense: "We realized through ultra-high resolution image sensor scaling is possible to achieve, but one think you want such a large size, such a high-definition image sensor into a smart phone, I feel amazing. Although this 5 years ago, but now I am still feeling. "
In the end, Nokia's team of engineers at the top of the 808 PureView practice this principle. Arak Hu and colleagues presented to the media last week, this camera technology look excited. After all, the past five years they have been in secret development of this technology.
The ultrahigh of 808 PureView smartphone pixels of course will bring some benefits. A big advantage of this technique is that it can make you a picture or video zoom in three or four times while still keeping a very high resolution.
Secondly, the 808 PureView camera through the so-called "over-sampling (oversampling) to reduce the photo size, but also make full use of the information in a large number of pixels. Nokia said that by seven extra pixels in each pixel used to understand, it can take clearer photos of five million pixels.
Nokia R & D team is also all over the world around, shoot photos around, testing the quality of the camera. In January this year, the opening of the International Consumer Electronics Show, Arak Hu I are in Las Vegas, wanted to take some photographs. But everywhere, journalists and competitors, Arak Hu can not start.
To deceive the public, Hu Arak with a thick rubber box phone wrap, also working the phone close to the jacket at to avoid some people close to the screen to watch, discovered the secret. Arak nonsense: "I feel a bit like James Bond (James Bond), holding a special new equipment to perform a secret mission. I have time carefully, but also really fun."
Nokia fixed liable criticism is that it will be the latest camera technology first used in the Symbian platform is destined to disappear, rather than its future fate of the Department of Windows Phone platform, especially in North America, the criticism will be greater . Nokia has even stop the the Saipan mobile phone sales in the United States.
Nokia has developed the Symbian platform 808 PureView of smart phones, the following two important reasons. First of all, the Nokia as early as five years ago began developing this product, and the company until last year did not realize the importance of the Windows Phone platform.
Second, precisely because of the complete control of the Symbian platform, Nokia only free "operation" on the application and operating system. In other words, Nokia eventually will this technology to the Windows Phone platform, although a specific timetable is still unknown.
