The Finnish giant has introduced the successor to the traditions of Nokia N8, equipping it with 41-megapixel camera – take a look at what lies behind such striking characteristics.
Rear camera Nokia 808 PureView really has a CMOS sensor with 41 megapixels (7728×5368) with the size of the sensor 1/1, 2 inches, which is 2.5 times greater than that of N8. Of course, you can take pictures in resolutions such as the giant 38-megapixel (7152×5368) for the 3:4 format and 34-megapixel (7728×4354) for the 16:9 frame – the whole area of the sensor once unattainable because of its squareness, but the main task of the new camera phone did not put it.
Camera Phone Nokia 808 PureView proposed an interesting technology over-sampling of pixels, which is shooting in the usual resolutions of 2, 3, 5 and 8 megapixels combines adjacent pixels in a “superpiksel” redeemed from the curse of traditional photographers, such as noise, poor color, lack of lighting . So, for example, at 5 megapikelnoy shooting each pixel is obtained as the integration of eight adjacent, and at 3-megapixel – already fourteen. The resulting pictures are incredibly sharp, colorful, balanced brightness.
Due to oversampling appeared interesting mode of photographing with a digital zoom with no loss of quality: the image broadcast through the viewfinder screen Nokia 808 PureView, can be approximated by a maximum of three times. Clearly, with the largest approximation get the highest quality 2-megapixel picture.
If you try fotomaksimum with a resolution of 34 and 38 megapixels, how creative, on closer inspection personnel will rush into the eyes, while maintaining the expected definition, a fair amount of noise images – and what you want from such a dense packing of the abundance of light-sensitive 1.4-micron elements on the sensor, the physical dimensions of which are modest in comparison with professional cameras. To the great joy, shooting in any mode is executed without any delay.
It is clear that in most cases there is no reason to shoot with a resolution higher than the five to eight megapixels – the image is usually stored on your computer and from time to time are reviewed. And the truth: for summer travel are sufficient personnel required five to eight megapixels, and pictures to upload to social networks in general can be a two-megapixel. Only professionals working in advertising or media industry, the incredible importance of resolution, reflected on television, posters, billboards. That is why manufacturers of smartphones stopped chasing figures, with greater emphasis on improving the quality of optics and the inclusion of technologies such as reverse lights.
Nokia 808 PureView can shoot 1080p30-video, and with the possibility of a four-fold approach without losing quality. If you lower the resolution of the video, zoom capabilities expand. So, 720p30-video zoom lens has a six-fold, again with no loss of quality, and 360p30 – has twelvefold.
Knowing what good optics installed in the Nokia N8, we can safely claim to the appropriate level, that of the Nokia 808 PureView. Clearly, it is a German brand, Carl Zeiss and going by the way, at the Minsk Mechanical Plant named after Vavilov. The optical design of the camera, including a group of five aspherical lenses plus an additional mechanical shutter, and is characterized by a focal length of 8.02 mm aperture F/2.4, focus range from 15 cm to infinity.
Phone immediately got two flashes: Xenon and LED for taking pictures for the video.
By itself, the camera module 808 Nokia PureView large, with approximate dimensions of 1 cm in all planes. That is why the rear surface of the phone is so obvious bulge. In general, the device seems heavier than the preceding cameraphone N8, and places like N95. Convenience and ergonomic design for new products has rounded edges, body gently curved, like Galaxy Nexus, a plastic material garments pleasing to the touch.Product thickness is 13.9 mm in the chamber reaches an impressive 17.95 mm, rather big mass is 169 g
For the Nokia 808 is responsible PureView single-core 1.3-GHz processor, and processing large amounts of data from the camera, engaged in a single chip. The RAM is 512 MB.
The smartphone is equipped with a 4-inch ClearBlack AMOLED, alas, without any gain to the narrative in the phones of the Finnish giant’s resolution of 640 by 360 pixels.However, if we were talking about the same Google Android, then it would be appropriate to complain about the low resolution display. It also rules the ball mobile platform Nokia Belle (the company recently refused to call it as Symbian): it is felt all over the slowness, from navigating menus to scroll through Web pages. Although the built-in clients are Facebook and Flickr, who are able to upload photos to their network and application gallery soon enough to cope with their tasks.
The choice in favor of the dying Symbian is really determined by what it is for this platform over five years to develop complex algorithms for image processing, and optics of the camera itself to fit it. If you would have to take Windows Phone, claimed modification would be too time-consuming, which Nokia is already there.
Capacity flash storage is 16 GB, there is a slot for flash cards format microSD. However, the amount of internal memory should last a long time, because Nokia has used special algorithms to compress the final photographs, avoid shots from the details that other cameras include, but not have to. The size of a typical 5-megapixel JPEG-image does not exceed 1 MB. An example of the algorithm is simple: just remove the frame from adjacent to each other black and white stripes – Other cameras will paint the gray spaces between the contrasting colors, while the Nokia 808 PureView do everything correctly, without engaging in planting artifacts.
By the way, Nokia 808 PureView writes video with stereo sound, and as comparable to that of a musical CD. Argued that audio is not distorted, even in extremely loud environments – up to 140-145 dB – for example, at rock concerts.
Raisins are put Dolby Headphone technology to convert stereosoderzhimogo in surround sound in any headphones and Dolby Digital Plus for 5.1-channel surround audio playback.
Of the others: communication 3G HSPA, A-GPS, NFC, Wi-Fi 802.11b/g/n + DLNA, Bluetooth 3.0 and FM-radio + RDS, front VGA-camera, connectors, 3.5mm audio, microUSB and HDMI The battery 1400 mAh.
And for a snack: Nokia does not deny that her experience with the 41-megapixel camera can be repeated on other platforms – it is appropriate to expect a camera based on the Windows Phone.
For sale Nokia 808 PureView in black, white or red color appears in the spring at a price of 450 euros, or $ 600.
