According to Economic Daily News, Apple will release at least one iPhone with three lenses in 2019.
The third lens will be used for 3D sensing and enhanced zoom, as predict by analyst Jialin Lu. The triple-lens camera system will enable advanced 3D sensing via stereoscopic vision, with two of the sensors able to capture images of a single object from different angles. To obtain the distance between the iPhone and the object, a triangulation method would then be used. The 3D sensing technology would be used for improving the AR (Augmented Reality) capability.
Lu also predicts that the third lens will enhance the zoom function, because would likely have a longer focal length.
There are many concepts for the triple-lens rear camera iPhone. We'll show them below.
