As the main feature of modern mobile phone competition, it has been passed on by crazy dual-lens before the launch of the new iPhone. While only 7 Plus features a dual-lens camera, the iPhone and the July 7 Plus lens can have many other eye-catching new features. The most important thing about the dual lens is that it achieves the functionality that traditional mobile phone cameras don't have.

Focal externalization:
With the arrival of the iPhone 7 Plus, a lot of people could begin to first contact to the Computational Photography (Computational Photography) this concept, it is using data from multiple cameras on small devices compute a richer and better image. There are a lot of possibilities for computing photography, and the first and most important point is that smartphone cameras can also be used to create a virtual effect. When shooting the iPhone 7 Plus, the dual camera system USES two lenses and advanced machine learning techniques to create a blurry background effect while ensuring the body is clear. This effect is often achieved by using SLR cameras.

The iPhone 7 Plus telephoto lens is a surprise
The iphone 7 Plus has finally been used with a combination of a wide-angle mirror + a long focal lens. With the help of telephoto lens, the iPhone finally realized historic optical zoom, and the optical zoom is not common telescopic card machine, although only the light of the double variable ratio, but the pronoun that optical zoom is lossless image quality. The advantages of optical zoom are obvious when compared with the inadequacy of the image quality.

Three times the exposure and F/1.8 high efficient sensor
Sensor size and directly determines the image quality of camera lens quality, in the smart phone, as a result of the limitation of size and thickness, can't infinite to improve the optical quality of the sensor size and lens. In this case, improving image quality by adding a second camera is a natural choice.

Double optical zoom
Photos of the iPhone 7 and iPhone 7 Plus can be twice as high. As long as everyone USES an old iPhone and a new iPhone 7 in the same dark environment, the iPhone 7 will be twice as luminous as the old iPhone. In addition, two machine has function of optical hand shock proof, and iPhone seven Plus two more x optical zoom and nondestructive 10 x digital zoom, in home can only after photography more focus, make the color of the image level more clearly. And the iPhone 7 has five times as much digital zoom as the previous iPhone 6S Plus.

Add four double color temperature leds
The surprise was that the iphone 7 and the iphone 7 Plus were created on the complementary lights, and the original two double color leds added to four dual-color leds. What does that mean? The flash brightness is 50% higher, and you can create better lighting effect at night. In addition, the correction effect of double color temperature LED on the color difference is still effective and enhanced, and the white balance can be kept more accurately.

Optical image stabilization of devolution, the addition of optical zoom, a larger aperture coupled with excellent optimization algorithm, which give iPhone7 / iPhone7 Plus on mobile phones king throne provides the full confidence, then will there be any changes in the future mobile phones? Let's wait and see!
