With the development of photography technology, 1 inch has become the threshold for entry in professional equipment. And Xiaomi’s newly released Xiaomi Mi 11 Pro and Ultra are equipped with the 11 12-inch Samsung GN2, pushing the CMOS size of the mobile phone to a level close to one inch, bringing a photographic effect comparable to that of a professional camera. In addition to hardware upgrades, Xiaomi has also used algorithms, self-developed chips and other black technologies to further improve the image performance of new products and start a wave of mobile phone image explosions.
For the majority of machine friends, the photography function has never been too powerful. Photography technology has therefore become the focus of competition among major mobile phone manufacturers, and the image sensor, which is the most hard-core indicator for judging image quality, has attracted more attention.
With the development of photography technology, 1 inch has become the threshold for entry in professional equipment. Xiaomi’s newly released Xiaomi Mi 11 Pro and Ultra are equipped with a 1/1.12-inch Samsung GN2, pushing the CMOS size of the mobile phone to a level close to one inch, bringing a photographic effect comparable to that of a professional-grade camera. In addition to hardware upgrades, Xiaomi has also used algorithms, self-developed chips and other black technologies to further improve the image performance of new products and start a wave of mobile phone image explosions.
Crushed to death
There is a well-known saying in the photography circle: “The bottom level is crushing people to death.” For smartphones with inches of gold inside the fuselage, having a larger sensor can make the shots more pure and have better results. The Mi 11 Pro is equipped with a super-outsole sensor, which can be said to be a big plus for fans of heavy and large professional cameras that like photography.
In the past two years, Xiaomi mobile phones have attached great importance to the image experience, and have continuously improved the image quality through large size and high pixels. This time, Xiaomi 11 Pro’s GN2 1/1.12-inch 50-megapixel sensor, jointly developed by Xiaomi and Samsung, has a single pixel size of 1.4μm and a four-in-one 2.8μm. It not only reaches the limit, surpasses and even exceeds the CMOS size. Rolling down mobile phones in the same gear, but also opening up the mobile phone Soc, ISP, AI, and OS to work together to develop a new track to the limit of one-inch imaging capabilities.
If you don’t have any idea about the 1/1.12 ultra-outsole of Samsung GN2, you might as well compare it. Samsung GN2 has a photosensitive area of 1/1.12 inches, which is nearly 5 times that of the iPhone 12 Pro, and is more than double the size of the Sony IMX689, and is very close to the one-inch outsole of the Sony Black Card RX100M7. Friends who are interested in photography know that the larger the sensor area, the higher the amount of light and the better the image information collected at the physical level, the more organic the final imaging effect will be. The horror parameters of Samsung GN2 make it the largest image sensor in the industry, which will bring better light capture capabilities, better performance in terms of color and noise, and better photographic imaging effects.
Win the dark focus battle
In addition to taking the lead in pixel size, Mi 11 Pro and Ultra have also expanded their advantages with products from other vendors through hardware and software innovations.
Xiaomi provides a dToF 64-point laser focusing system, an outsole main camera OIS anti-shake solution, and a very competitive night owl algorithm. With the blessing of these black technologies, the adaptability of Xiaomi 11 pro and Ultra has far exceeded that of professionalism. 1 inch black card camera. At the same time, coupled with the 128° ultra-wide-angle lens, you can shoot a super shocking wide-angle lens, which is very suitable for users who want to shoot large movies on travel, even in a dim environment, they are not afraid at all. In addition, at the press conference, Xiaomi directly used the black card to compare the real shots with the Xiaomi 11 Ultra. Judging from the proofs at the scene, the visibility of the Xiaomi Mi 11 Ultra seems to be better than that of the black card in low light conditions. It can be seen that Xiaomi has really made a lot of effort in the photography ability this time.
The dual native ISO Fusion technology of Xiaomi 11 Pro allows two image information of different ISOs to be directly fused and output to the processor, which not only shortens the imaging time, but also allows the dark and highlight details of the film to be preserved more completely, the overall color is more natural, and the color transition is more complete. Smooth, closer to human vision.
All-pixel omnidirectional 8-core focusing is a new technology brought by GN2. GN2 innovatively cuts the green pixel diode focusing line to form an “up-down” structure, upgrading the left-right phase comparison of the traditional 2PD focusing to up-down and left-right full-phase comparison. The new technology solves the situation where 2PD is invalid in a scene where the vertical texture changes obviously and the horizontal texture changes are not obvious when taking pictures. For example, if you take a picture of a thin horizontal patterned clothing, the full-pixel omnidirectional 8-core focusing will be extremely fast.
Algorithm-the fundamental power of mobile phones surpassing cameras
Faced with cameras with larger volumes and single functions, mobile photography still has inherent shortcomings. The only way to make up for this shortcoming is the algorithm card. For example, when users are shooting high-speed sports, shooting small objects, shooting with complex backgrounds, shooting in low light, and shooting in low-contrast environments, it is inevitable that the focus point will be clicked, but the phone will not be aligned. With the latest algorithm support of Xiaomi cameras, these problems can be easily solved, and users will no longer be “powerless”.
Xiaomi Mi 11 Pro is definitely a camera artifact for those who like to capture and take pictures of moving scenes. When it recognizes that the subject is a person or a cat/dog, it can perform smart focus following. The principle is that the lens recognizes the change in optical flow, AI recognizes the subject, calculates its movement trajectory, and calculates appropriate exposure parameters at the same time to make the picture More coordinated. Based on this function, Xiaomi also integrated knowledge graphs and AI machine vision capabilities, and launched a significant area detection algorithm on Xiaomi 11 Pro. This algorithm can identify the “special area” in the shooting screen, perceive what the user wants to shoot in advance, and align the motion, luminosity, and color to calculate, and give reasonable exposure parameters.
Night scene-it’s the trend but also the show
Night scene shooting has always been a difficult point in photography. Like focusing, mobile phone cameras are also at a disadvantage in low-light shooting. The “Night Owl Algorithm” launched by Xiaomi this time for low-light shooting has solved the problem of poor shooting and unsatisfactory shooting under low light. For those who like to shoot night scenes, the “Night Owl Algorithm” is good news.
This algorithm is aimed at the 0.02-0.1LUX illumination environment, and the sensitivity has reached the limit of traditional black and white cameras. In this environment, Xiaomi Mi 11 Pro can enhance multi-frame fusion photos through AI in this environment, and take photos with accurate colors and clear outlines, especially In terms of noise suppression, it outperforms cameras of the same grade, which can be described as the “new night vision benchmark.”
In addition to the night owl algorithm, Xiaomi’s first folding screen mobile phone MIX FOLD is also equipped with Xiaomi’s self-developed surging ISP chip, which is a chip independent of the system chip for independent image information processing, which can greatly improve the night view of MIX FOLD. Shooting performance. Especially in the performance of complex details in the dark light, compared with the models that only use the system ISP, Xiaomi MIX FOLD can present more details and a more natural contrast of light and dark, eliminating the smearing effect.
On the whole, Xiaomi has spent a lot of time in photography technology this time, and it has also brought big surprises to machine friends in terms of imaging. For those who rely on mobile phones to take pictures and record videos, Xiaomi Mi 11 series Both the Cup and the Super Cup deserve attention.
