Nokia appears to coincide with the Pure 808 smartphone View back to catapult into the top league of multimedia smartphones. The technical data pertaining to the camera module of the Mobile World Congress (MWC) featured phones are certainly quite impressive: 41 MP sensor, 2.4 f Carl Zeiss optics. Full HD 1080p video thanks to the high Sensoraufloesung receives such a lossless 4 x zoom, at 720p, there is a loss-free 6-fold zoom, which works also completely silent, because he only enlarges the section. It captures the video in High Profile H.264 at up to 25 Mbps. The large 1/1.2 sensor of the Nokia 808 Pure View is intended to provide the relatively high Lichtstaerke the staggered look much sharpness for film look. The active workspace of the 41 MP sensor is amazing 7728x5368 pixels, these,be bsp. 7728x4354 pixels for 16:9 video formats used as oversampling. The dimensions are: 123.9 x 60.2 x 13.9 mm (17.95 mm at the camera), 169 g Memory: 16 GB, expandable to 48 GB (Micro SD). . As display a 4 "AMOLED display comes with a 630x360 pixel resolution for use on interfaces available include USB, bleutooth, HDMI etc (is the Nokia Pure View 808 no LTE phone.) For disposal as the Symbian operating system is used -. Prices and availability are not yet available to us. Who more technical background for the new Nokia smartphone Pure View would like to find 808, find (Here) is a White Paper from Nokia Download Here is a quote from it on the video autofocus function.:"Improved video autofocus autofocus video of what that area needed to be improved dramatically. Because of Nokia 808 Pure Views much larger image sensor (5 times larger than rival smartphones) the optics give you A relatively shallow depth of field. Whats more, So were using oversampling techniques in video to Achieve our holy grail of low visual noise with extremely high levels of detail. As a result, we made our autofocus system more precise, sensitive and controllable. You get continuous autofocus in all shooting modes, but also provided easy access to weve in On / Off control. In Off mode, the lens is set to hyperfocal, making it easier to get across a wide range acceptable focus of subject focus distances while Eliminating hunting. Theres so touch autofocus for video and still images. In Creative shooting mode, we&ve gone evenfurther. A long touch on the viewfinder will bring up a pop-up window UI, where you can select Automatic or macro. Close-up focus is much improved in macro, while automatic does all the work for you. "And another quote from it on oversampling," On a more technical note ... oversampling Bayer pattern Eliminates problems. For example, conventional sensors 8MPix includeonly 4Mpix green, red and 2Mpix 2Mpix blue pixels, interpolated to 8Mpix Which are R, G, B image. With pixel oversampling, all pixels become true R, G and B pixels. Whats more, based on Nyqvist theorem, you actually need oversampling for good performance. For example, audio needs to be sampled at 44 kHz to 22 kHz get good quality. " u003cimg src=
