Due to the characteristics of the brand, the current mobile phone double-lens solution is numerous, and what do you know together?
From the top left, clockwise order is: LG G6, ASUS ZENFONE 4, Huawei P10 Plus, Apple iPhone 7 Plus, Xiaomi A1.
Before the iPhone has not officially released, not only the name of "smartphone" is still known. It is a ridiculous hope that the mobile phone is a portable camera. Today, when it is, the camera has become an indispensable equipped with smartphones, and even starts with double-lens solutions. Perhaps due to the characteristics of the brand, the current mobile phone double-lens solution is numerous, and what is not let go of it.
First, Jingjing Sensor (Depth Sensor)
Speaking of a double-shot phone, the earliest or reaches of HTC EVO 3D in 2011. In 2014, HTC used a depth of field sensor in HTC One M8, and another double-lens combination was introduced. Through the depth of field sensor, the distance between the mobile phone sensing prospect is to the background, and the effect of the background blurred (or bokeh) is used through operation. However, its effect cannot be compared with the (digit) single camera. Because the single-eye camera can present different blurring effects according to the distance to focus, the mobile phone can only rely on the depth of field sensors and the flying effects presenting, and the degree of blorethrition from the remote background cannot be adjusted, and it is not true.
HTC One M8, there is a depth of field sensor on the main camera. (Figure / Turnover GSM arean) HTC One M8 taken. The website pointed out that it is not a photo of such a good effect to obtain such a good results, which can be seen except that the focus is clear, and the remaining background and prospects have different degrees of bloating effect.
Second, black and white photographic lens (Monochrome Camera)
The earliest began to use a color matching black and white double-time solution. According to the publicity, there is no black and white photographic lens of the RGB sensor, and the information of more light can be captured. In general, a color photo taken with a black and white lens is in theory that the details of the photo can be added to lower the noise. In addition to Huawei from P9, it has been used in the mainstream flagship in the mainstream flagship machine, and NOKIA 8 issued recently has also been similar. But strictly is still not seen.

Third, wide-angle camera (Wide-Angle Camera)
The LG G5 released in 2016 is the general lens with a combination of wide-angle lenses, which can provide a broad field of view, and will benefit from the scene, or group photo, or may bring benefits. "GSM Arena" believes that the shooting effect of the LG G5 / V20 wide-angle lens does not have the main lens, and the wide-angle lens sometimes distorts very serious. But this is a lot of improvements in this year's LG V30.

Four, telephoto camera (TelePhoto Camera)
In the double-fitting solution, the most often used is a telephoto lens. In contrast to the wide-angle lens, not letting you shoot, but let you shoot Yuan. Since the iPhone 7 Plus, mobile phone manufacturers use a 2X zoom lens in the secondary photographic lens, which means that the focal length is twice the main lens and can provide 2 times optical zoom capabilities. You can enlarge the image (after more than 2 times zoom) without losing the photo details, digital zoom can be provided, but the photo quality will be lost). iPhone 7 Plus and iPhone 8 Plus (right), all of the two-piece combination of telephoto + wide-angle lenses. iPhone 7 Plus main lens / telephoto lens (right) take a photo.

In addition to the ability to provide optical zoom, the telephoto lens is small due to the smaller aberration, so it is also suitable for photographing portraits. In order to optimize people like shooting effects, some manufacturers will also join the background blurring effect. The two-phase combination can produce a very good effect.
The solution is clearly disadvantage that the aperture of the telephoto lens is usually smaller, nor does it support optical anti-protection hobbies (iPhone X's telephoto lens also supports OIS, but the aperture is still only f / 2.4, than the main shot f / 1.8 is small).
Of course, the above is only a two-piece program analysis of mobile phone. Under the advancement of technology, the disadvantages of various types of solutions are expected to be resolved. From the above solution, "GSM Arena" believes that the scheme of telephoto lenses can not only provide optical zoom capabilities, but also have advantages in portrait shooting, as the current best choice.
