Of the rumors about the iPhone 7, I think there are three that stand out: the possibility of it being waterproof, the absence of a headphone port, and a new one. dual camera. A camera with two lenses can allow us to capture images with higher quality, but it could also have other capabilities, such as the ability to focus after taking the photo or video. Apple presented a patent in January in which it explains one of the uses that this dual camera could have.
La license describes an iPhone with a lens like the one we can find in the iPhone 6s and a telephoto lens on its side that would be able to capture photos and videos with extended zoom. Logically, special software would also be included so that everything could work. At the moment, Apple already includes software for digital zooming, but the new system would offer images with less noise.
The dual camera would allow us to record with two enlargements at the same time
The software that Apple describes in its patent could allow us switch between the two lenses without difficulty. In addition, it would allow us to enlarge the images more than what the software allows us thanks to the second camera without the user having to do anything. MacRumors has uploaded a video to his YouTube channel explaining how it would work.
The video explains an assumption in which we could record how a baseball player goes to bat, at that moment we record slow motion with zoom and returns to the normal frame once the ball is thrown. We can also see how a scene would be recording while controlling the zoom in the second window. To be honest, what I see in the video does not convince me, unless, as in slow motion, it allows us to choose how to save or share the video. In this way, we could do the baseball player scene, but it would be seen in full screen. If Apple adds a default transition or the possibility to choose between several, we could see in full screen how he is going to hit at normal speed, a transition, the batter in slow motion and close-up (hopefully, we would catch only the scene of the hitting the bat to the ball) and would go back to the original image to see how the player starts his career.
Logically, although it does not say anything in this patent, it is clear that with a dual camera we can capture images with two references, which imitates vision. If Apple did not include the possibility natively, I think it would only be a matter of days before a third-party application arrived that would allow us to simulate a 3D effect. But for that the first thing that has to arrive is an iPhone with a dual camera, which could be in six months. Will we see it in September?
