Apple has finally taken the plunge twice photo sensor for the iPhone 7 Plus. At the conference, the Cupertino company has introduced two features from this new technology: a hybrid optical zoom – digital and 3D analysis of a scene for creating a blurred natural background, but software <. / p>
in the Android world, smartphones feature dual sensors Photo existed for some years now. These include the HTC Evo 3D which used its double sensor to project a 3D image on the screen of the smartphone, the HTC One M8 that used the second sensor to measure the depth of field and able to adjust focus post , Huawei P9 using a monochrome sensor assisted by a conventional sensor for enhance the quality of the image or the LG G5 which uses two modules pictures with two different focal lengths, which is reflected in practice by two levels of optical zoom. Apple has incorporated most of these features to its iPhone 7 Plus
Hybrid Optical Zoom. – Digital
The dual sensor and allows for a hybrid digital zoom – optical we had already seen in a patent. Thus we find a camera module with a 28mm lens and another module with a 56 mm objective. Much like the LG G5, the iPhone 7 Plus will therefore enable to use a choice of one of the two focal lengths to get a photo roughly zoomed. Apple is still a bit further by offering a hybrid digital zoom – optical because it seems that the iPhone uses both pictures and a special algorithm to allow to obtain a digital zoom between two focal (between x1 and x2), and even beyond, up to x10. This will clearly verify this assertion in practice and compare its operation as LG G5
An artistic bokeh
the other great feature associated with this dual sensor is software depth of field to achieve a blurred background, just like the bokeh that can be obtained with SLR cameras. A feature that was first seen in the HTC One M8, which is still found today on the Huawei Honor P9 or 8. The dual sensor is then used to take the picture of a subject and then set the blur in the background post . With the iPhone 7 Plus, Apple offers nearly the same functionality that would appeal to “ advanced a machine learning technology ” to analyze the three-dimensional scene and apply a soft focus on ‘background, but will be available after the launch of the iPhone, a clue suggesting that the technology is more advanced than the competition, or Apple encounter some difficulties in correctly implement its algorithm.

Stabilization and RAW
Along with these features, the iPhone 7 and 7 more are now using a new sensor 12 megapixel camera with optical stabilization and a lens with an aperture of f / 1.8. Features already seen in the Android world with the opening of f / 1.7, Galaxy Note 7. Finally, we note the emergence of the possibility of shoot in RAW format , which is already possible since last year Android.
And the rest?
however, we regret that Apple does not dwelt more on the benefits of dual sensor. Rumors indeed evoked in low light of the best pictures by mixing two images from the sensors in the manner of Honor 8 using the second sensor to improve the image. See you in a few weeks for a full review of the iPhone 7 Plus, which will be available from 16 September for 909 euros 32GB version.
