With the continuous development of mobile phone technology, the performance of mobile phones is also improving. In recent years, the mobile phone camera has changed from a single camera to a dual camera, and the dual camera has become a major selling point of mobile phones. So, can the increase in the number of cameras really improve the photo effect of mobile phones? The more cameras, the better?

Vivo X9 says, "Illuminate your beauty, with 20 million in front and soft light for double shooting"; OPPO R9s said "this moment is clearer"; Xiaomi 6 said that "zoom double camera makes people more beautiful"; Huawei P 10 says "master portrait photographer", and OPPO R 1 1 says "20 million yuan before and after, and the photos are clearer"; Gionee S 10 said that "four-shot photography is more beautiful" ... but the effect, whoever uses it, is basically no different from a single camera.

Judging from the camera function of smart phones, the factors that determine the image quality can be roughly divided into three factors, one is the size and quality of CMOS, the other is the lens quality, and the third is the software optimization ability.

At present, the main manufacturers in CMOS field are Sony, Toshiba and Samsung, which control the technical discourse power of the whole industry.

OmniVision(OV) was originally an American CMOS manufacturer specializing in the field of mobile phones. In 2009, the market share once reached 28%, and the shipment volume was higher in Bisogni. But in recent years, the market share of OmniVision is only about 17%, and it is still a low-end product. At the beginning of 2065,438+06, it was acquired by an investment fund composed of China Qingxin Huachuang, CITIC Capital and its subsidiary Jinshi Investment.

In China market, the main mobile phones we see are CMOS provided by Sony and OmniVision. Among them, the products with the size of 1/3 inches and the pixel size of130,000 are mainly supplied by Sony, and OmniVision only accounts for a small part, while the CMOS with 20 million pixels is only produced by Sony.

In fact, our common camera for mobile phones has a CMOS area of only 1/3.2 to 1/3 inches. Sony uses a relatively large size, 1/2.3 inches, while Nokia Lumia 1020 was10.

If you compare the CMOS of the mobile phone with the Quan Huafu SLR, the CMOS of the 1/3-inch mobile phone is only about 1/40 of that of the SLR, so although the pixels of the mobile phone are not much more than those of the single comparison, the picture quality is not bad at all, and the bottom is rolling.
