One of the novelties of the Samsung Galaxy S7 and S7 edge is represented by the rear camera. Although sensors are available from 20 megapixels and beyond, the Korean manufacturer has not increased resolution than the Galaxy S6, giving priority instead to other features that allow you to get perfect shots in any light condition . The result is images with quality comparable to that of high-end DSLR.
The Galaxy S7 and S7 edge integrate a 12.2-megapixel camera (4032 × 3024 pixels). The sensor Sony IMX280 then an aspect ratio 4: 3 and is off 1 / 2.5 inch. As many know, the picture quality does not depend solely on the resolution, but also by other parameters. The pixels of the sensor are wide 1.4 micron (56% more than the Galaxy S6), while the lenses have an aperture f / 1.7. These two combined features allow you to capture 95% more light compared to its predecessor the Galaxy S7. Another important change concerns the focus.
The image sensor Dual Pixels used for the rear camera divides each pixel into two photodiodes to perform phase detection ( PDAF) and thus improve the autofocus. The technology implemented by Samsung allows to send the light from the lenses to two image sensors separately for adjusting the focus, in a way similar to human eyes. As a comparison, only 1% of the pixels of the sensor in the Galaxy S6 is able to recognize and phase contrast, while the Galaxy S7 pixels are the 100% .
the Samsung Galaxy S7 and S7 edge offer three new shooting modes. Motion Panorama Shot allows you to capture the movements of the subject during a panoramic photo. Hyperlapse , on the other hand, reduces the duration of the recording to get a video time lapse stable, thanks to vDIS (Video Digital Image Stabilization). Selfies Flash , finally, uses the AMOLED display as a flash, when the user clicks selfie in low light conditions (less than 20 lux).
