one of the biggest strengths of the iPhone has long been his camera, and a new patent application from Apple shows how it could be improved still further in the future. The application first discovered by patently Apple, is obviously for a dual system of the camera on the back of your smartphone. Apple is in the foreground, at least in this patent is the photographer a way to enlarge without losing image quality.
The idea is that a camera had a wide-angle lens, the other had a much deeper focal length. Then you could switch between the two without resolution how to use digital zoom.
Both cameras could be shooting at once.
Of course there are many other ways that Apple could decide to a Dual camera system. A 3D camera is among them, but it seems unlikely, unless Apple also a 3D screen to display them. Also as a zoom system, there are more than just switching from one to the other to take photos. The patent application proposes a could be used to generate still images, while the other entries Video; Apple even imagine that the camera app could stitch the two together, with the exposures to highlight important moments. The cameras can also shoot at different speeds or different resolutions.
As always with patents, it is difficult to say how seriously considering Apple. But there were some rumble in the past on a Dual camera system on the iPhone. Apple his own opinion John Gruber mentions only over a year ago that he had heard the iPhone could adopt a "two lens system" in the future, what the camera "DSLR picture quality." At least one recent report, even if questionable truth, brings the rumor that for the iPhone 7. The idea that Apple could dramatically improve the quality of the image with a second camera still seems questionable, but give iPhone owners a way to avoid using Digital Zoom, would certainly be a way of improving the quality, even if only in certain situations.
