What is the truth about cell phone Leica lenses May 17, 2018

From the previous Nokia, there was a familiar and unfamiliar vocabulary on the camera of the mobile phone - Karl Zeiss. The blind man thought that it was a lens produced by ZEISS. In fact, Carl Zeiss was involved in designing and tuning. Not Karl. Zeiss independently designed and produced, but its lens indicators reached the Carl Zeiss optical standards. In addition, there are OPPO's Schneider certification lens, Huawei's Leica certification lens, etc., what kind of technology are used to support its camera performance? Let's take a look at the phone lens.

Whose lens is Leica and Zeiss certified?

The above-mentioned Leica ZEISS-certified lens is not designed and produced by the company, but is manufactured by other manufacturers. After the sample is designed, it is sent to the lens manufacturer to conduct standard inspections and modify some areas that do not meet the standards. The final qualified lens will be marked with its logo to prove that the lens meets the manufacturer's standards. In simple terms, the difference between a certified lens and an ordinary lens is like the difference between a cow's head and a dog's head on a camera. A certified lens is like a red circle, a symbol of status.

Zeiss and Nokia's many mobile phones, will be added to the lens next to the letter Carl Zeiss, said the camera lens is Carl Zeiss certified, the lens quality and imaging will be guaranteed. However, Leica's cooperation with Huawei will be even higher. Huawei uses the Summilux optical structure under Leica, and Leica participates in the specific design and manufacturing process. Dispersion ghosting control of lens imaging has deep cooperation, and signal processing algorithms are also helpful. Leica's certification is not limited to the lens. From the former's design and manufacturing to the later imaging algorithms, it has a deep cooperation, which also makes the Huawei P20 series win the top spot of DxO Mark. However, this is only participation and help, not independent establishment and manufacturing.


Who is the core part of the camera?

Friends who are familiar with the camera know that a good lens is useless, and the body is also very important, and the manufacturers responsible for the production of the body are Sunny, Titanium, Truly, Lite-On and Ophelia, most of the sensors are famous. Sony. Some low-end phones will use ready-made solutions directly, and high-end phones will use Sony's top sensors or customized versions.

There is a lens, and even an algorithm can produce a film. Now the most famous image solution provider is a company named Arcsoft Hongsoft. Many of the mobile phone's post-image processing solutions, especially the dual camera lens, are There is technical support provided by RainbowSoft. The current mainstream dual camera solution is the iPhone's wide-angle + telephoto camera, the purpose is to achieve optical zoom; as well as Huawei's color + black and white lens, through the black and white camera's good noise control performance, with color camera polishing, can be Improve the picture quality in dark environments such as night scenes.

There is certainly good certification, not certified is not necessarily bad

With a certified lens, photography will have advantages over ordinary lenses, especially in terms of optical quality, regardless of what sensors, apertures, algorithms and other factors. But I think it's more of a sentiment. Many people buy this phone seems to be recharging their faith. Is it not good to take a camera lens without certification? In fact, you can look at the iPhone without any certification. The picture quality of the camera is better than many certified mobile phones. It also involves the problem of late algorithm. In general, certification does not mean production, but it is produced according to the standards of Leica or Zeiss. It is not a product of a certified company. It will help improve the picture quality.
