Secret Nokia 4100 megapixel phone research and development process: preparing the five-year

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.

41 million pixels for the Nokia 808 into focus

Nokia has just released the 808 is the world's first camera smartphones PureView technology. It may become a family of Symbian (Symbian) Finally a flagship camera phone. The main hardware configuration: 4-inch capacitive touch screen, Material of AMOLED, with the CBD, for nHD resolution; 1.3GHz processor; 16GB internal storage, support for MicroSD card expansion slot; certification of Carl Zeiss (Carl Zeiss) optical lens; large-size sensor, 41 million pixels; Nokia original pixel sampling techniques; equipped with Bella (Belle) the FP1 system (improvement) original Bella systems, to do; weight of 169 grams.

This unique sampling techniques are: the coordination of hardware and software, combined with unique algorithm, so that a "Pure" pixels separated into 7 pixels.

I asked the Nokia Staff: "This is What kind of ideas?"

His answer was interesting: "We do not want to cause an arms race in the camera, just in everyday applications, the consumer does not need to print a substantial advertising posters, so the significance of the high pixel exactly where? Is that after shooting a distant object , and then amplified the interception of which one. "

In other words, Nokia do not want to use the optical zoom lens to increase the thickness and weight of the phone, turned to take another digital zoom.

 "Pixel-for-zoom"

In the official press release, we can see this description:

This camera can shoot 1080p resolution video rate of 30 frames / sec, the period can be used four times lossless zoom (equivalent to a small piece cut from the large-size sensors). 720P resolution six times "lossless zoom; 12 times lossless zoom" nHD (640 x 360) resolution.

Ready before the period of "pure shooting scenes" trailer, you can see the vision of the 808 shooting and close-range, which is "lossless zoom" effect. No optical distortion, did not seem too much noise, it really is an advanced digital zoom means.

"Only the pixels on the incorrect

Of course, the digital camera system is definitely not only able to measure the pixel index. Is like saying that Hasselblad is the H4D-50, with 50 million pixel sensor. This Kodak sensor to 36 x 48 mm, double the existing 135 full frame sensor and equipped with a range of support to focus and lock technology, the price of sets of machines can be sold for more than two hundred thousand.

Nokia 808 apparently can not be used with Hasselblad, but this mobile phone is enough Nokia "do not take the unusual way".

Nokia approach has been recognized by consumers, believe that other manufacturers will follow. A variety of "Do Level" hundreds of millions of level "phone posters, but also far away from us.

Bella the Feature Pack 1

The 808 equipped with Bella (Belle) Feature Pack 1 version of the system, compared with the original system of Bella could not see any surface changes. In fact only make a fuss on the system stability, performance optimization.

Nokia 700 , 701, 603 users can upgrade to this version of FP1 in the summer. But earlier, E7, C7 and N8 are not the upgrade services.

Price?

If you by a previous hardware specifications of shock, it should quiet down the Nokia 808 the price. No contract in the European market retail price is € 450!. feed ifanr, ifanr is the best cutting-edge science and technology blog media, they panoramic concerned about the mobile Internet, the coverage of the entrepreneurial team, the most influx of smart handheld and the coolest Internet applications, a deep understanding of industry eco-smart products and mobile applications committed to "an independent, forward-looking, in-depth" original reports and analytics.
