Nokia-808-PureView-with-41MP-sensor



Nokia 808




Nokia has made the startling announcement that it has created a 41MP smartphone, the Nokia 808 PureView. Interestingly, in most shooting modes the camera will output 3, 5MP or 8MP stills, rather than offering its full resolution - promising greater quality and offering some clever features. And this isn't a trade-show concept model, this is a product that will be offered to the public, though details of when and in which countries haven't been announced. What's interesting isn't so much the pixel count as how it's used, so we took a closer look.

The first thing to realize is that this isn't a standard 1/3.2" mobile phone sensor, it's an unusual and remarkably large 1/1.2" type (five times larger). In fact, it's almost three times the size of the sensors in most compact cameras. As a result, its photosites are the same size as those in most 8.2MP cameraphone but the 808 doesn't try to create an image of the same quality, 5 times bigger. Instead it oversamples the image and then pixel-bins down to a smaller size (though there is a special 'creative' shooting mode if you want the full resolution - 38MP at 4:3 aspect ratio, 36MP at 16:9).

Nokia just announced a cameraphone with a 41-megapixel sensor. FORTY-ONE MEGAPIXELS. Naturally Nokia's sticking with Carl Zeiss lenses, but that 41-megapixel camera can shoot 7728 x 5354 photos in 16:9 format, or if you prefer 4:3, in 7152 x 5368. There's just one thing: It runs Symbian.
As snappers know though, it's not just the size of the sensor which counts. Nokia spoke of a feature called "over-sampling" which does something special with the pixels, grouping seven of them together to create one super-pixel, with the GPU processing one billion pixels per second. This basically means you can choose which size to take the photo in, from 5, 8 or 38-megapixel options.
Zoom-wise, it can lock in to up to 4x digitally, and if filming any 1080p video, it can zoom right into 3x (or 6x if you downgrade to 720p).
Along with being a camera, the 808 Pure View is also the first Nokia phone that can record audio in high-definition, plus has Dolby Digital Plus too.

iPhone 5

iPhone 5  come with 4G. This has been rumored for many months and was even previously reported on iPhone 5 Latest. What’s not obvious, however, is whether this will be plain 4G or 4G LTE–and, yes, there is a difference between the two. The difference between the two is simple: 4G LTE is considerably faster than 4G (we’re talking 12mbps download rate versus 5-6mbps download rate).
Perhaps even more noticeable than the beautiful 4G icon in the iPhone 5′s taskbar is the size of the device. In looking at the first picture, the bigger size isn’t that noticeable; however, when you see picture 2, it’s obvious that the iPhone 5 is bigger than the previous iPhone models. How much bigger? We don’t know yet, but judging by the pictures, we’re betting that the iPhone 5 is probably sporting at least a 3.7 to 4.3″ display.
