From Apple:

iPhone 7 Plus doesn’t have just one entirely new camera system — it has two. The same 12MP wide-angle camera that’s on iPhone 7 works with a 12MP telephoto camera that can get even closer. That means you can get higher-quality zoom from farther away. And with an all-new depth-of-field effect (coming soon), portrait shots will look better than ever. Say hello to the world’s best photo op.
…
Depth-of-field effect.
Depth of field allows you to keep faces sharp while creating a blurred effect in the background. When you take a shot with iPhone 7 Plus, the dual-camera system uses both cameras and advanced machine learning to make your subject sharp while creating the same out-of-focus blur in the background — known as the bokeh effect — previously reserved for DSLR cameras. So no matter what’s behind your subject, it’s easy to create a great portrait.

Dual camera smartphones – the missing link that will bring augmented reality into the mainstream — from theconversation.com

Excerpt:

Smartphones boasting “dual cameras” are becoming more common, and news that they will feature on the just-announced iPhone 7 Plus indicates the arrival into the mainstream. But while dual cameras may stem from efforts to improve picture quality, it has the potential to lead us down much more interesting paths: the real story may be that Apple is using dual cameras to position itself for the augmented reality world ushered in by the Pokemon Go phenomenon.
…
The iPhone uses machine learning algorithms to scan objects within a scene, building up a real-time 3D depth map of the terrain and objects. Currently, the iPhone uses this to separate the background from the foreground in order to selectively focus on foreground objects. This effect of blurring out background details, known as bokeh, is a feature of DLSRs and not readily available on smaller cameras such as those in smartphones. The depth map allows the iPhone to simulate a variable aperture which provides the ability to display areas of the image out of focus. While an enviable addition for smartphone camera users, this is a gimmick compared to what the depth map can really do.

What Apple has is the first step toward a device like Microsoft’s HoloLens, an augmented reality head-mounted display currently in development.

Software that provides similar analysis of people’s poses and location within a scene for dual camera smartphones would provide a virtual window onto the real world. Using hand gesture recognition, users could naturally interact with a mixed reality world, with the phone’s accelerometer and GPS data detecting and driving changes to how that world is presented and updated.

Apple has not arrived here by accident. In addition to acquiring Linx, Apple also purchased augmented reality pioneer Metaio in 2015, suggesting a game plan to develop a mixed reality platform.

Dual camera smartphones: here’s why you should want one — from t3.com by Joseph Carey
The iPhone 7 Plus is meant to feature dual cameras, but why are two cameras better than one?

One sensor for the main image and one for the detail – dual cameras never usually have two of the same sensor.
