Recently, the United States Patent Office revealed a supernatural patent of Apple, which may appear in the flagship of the next generation iPhone 7 On.

This is another question about Duo Camera , but this time the function is no longer the same HTC And a bunch of domestic computers“ Take photos before focusing ”'s gag function. It has been rumored for so many years, iPhone It is finally possible to provide the optical zoom function, but this time we use the route of dual focus segment lens+algorithm synthesis.

It is different from the digital zoom that is just an algorithm for cutting photos, Optical zoom The image can be enlarged without loss. Through the movable optical lens, the lens can provide the field of vision of different focus segments. However, the structure of movable lenses is complex and bulky, so optical zoom is rarely used on mobile phones. But Apple's patent "understates" the problem of optical zoom and camera highlighting with dual lenses.

The principle of "dual optical lens" is very simple but very ingenious: both of them are main cameras, but they are equipped with lens focus segments In contrast, the short focus (wide-angle) lens is used to take overall wide-angle photos, while the long focus (roughly understood as a "telescope") lens is responsible for taking detailed photos at the focus. Through algorithm synthesis, the final picture is a lossless optical zoom and amplification towards the focus!

In the field of video recording, the iPhone can take its own interesting picture in picture videos. In addition, this dual lens finally enables iPhone to take full pixel photos when recording. Once this function is used on iPhone 7, it is estimated that it will be enough for Android manufacturers to learn for one year
