The successor of the iPhone 6 and iPhone 6 Plus could be equipped with a camera module with two lenses providing rangefinder function.
The camera sensors of smartphones have experienced serious changes in recent quarters with the emergence of systems with two camera modules, one of which provides distance information, like rangefinders on high-end cameras.
The smartphone HTC One M8 is a good example with its Duo Camera system with two lenses. This innovation could be in it or the successors of the current iPhone 6 and iPhone 6 Plus, if one believes John Gruber of Daring Fireball blog.
According to sources, Apple has also planned on a system with two lenses that bring photographic quality worthy to SLR cameras by exploiting both sensors on the back of the smartphone.
The site Apple Insider notes that the technology could be separate from that used by HTC and cited the case of Corephotonics startup that uses a two-lens system with different focal lengths to improve the performance of digital zoom and generate 3D effects.
It is far too early to determine which system could be used to get a picture quality worthy of a reflex, as already suggested by John Gruber. Apple has also earned many patents around the photographic techniques used on mobile systems including the Lytro to redefine the depth of field post.
