five、image：Big Mac GN2 is paired with two IMX586s! All the main photos will not find any opponent next year
- main camera
The mobile image sensor area on mobile phones has been slumped for quite a while after a explosion of growth.。
The reason is not difficult to understand - the development of mobile phone camera sensors once reached the point where they were close to their limits.，The larger the bottom, the longer the distance between the lens and the CMOS, the longer it will be，Increased thickness of mobile phone cameras is increasingly taking up the internal space of the body，Even manufacturers know that the larger the sensor area，The higher the light inlet，The better the image information collected at the physical level，The more conducive it is to final imaging，It's also difficult to cut a piece of space to make way for it。
Just when we thought the mobile image sensor on the mobile phone stopped，The first Samsung GN2 equipped with Xiaomi 11 Pro and Xiaomi 11 Ultra brings some surprises。Its most prominent feature is its huge size of 1/1.12 inch，Officially topped the mobile sensor size list。
Let me give you a brief introduction first，Samsung currently has two flagship product lines，And each takes a completely different technical route：One is the Samsung HM series that focuses on high pixels，Among them, HMX and HM2 are used by Xiaomi 10 series and Redmi respectively.；Another main focus is the Samsung GN series，The first generation GN1 is more familiar to everyone，GN2 is the latest generation。
1/1.12How big is the inch Samsung GN2? Let's take the 1/1.4-inch IMX689 as an example，Samsung GN2 is about 60% larger than it，In front of the 1/2.55-inch iPhone 12 main camera, it is like a Titan behemoth，Become the best mobile sensor area。

GN2 sensor，Not only can you stand out in 2021，Even next year，I believe it's hard to see an opponent。
In addition to the native super-large bottom, GN2 also supports four-in-one pixels in dark light environments.，Turns into 2.8um super-large pixels to improve photosensitive，This will result in brighter night scene photos。Simultaneously，It also supports dual-pixel enhancement for the first time，Then match the interleaved HDR、Smart ISO、Smart ISO Pro and other technologies support。
so that，Samsung GN2 can greatly improve the night scene shooting experience of Xiaomi 11 Ultra based on the Snapdragon 888 flagship ISP platform。During the experience of extreme dark light night shooting，Xiaomi 11 Ultra's super-large bottom advantage can be fully demonstrated。
As shown in the following comparison pictures，Photographing fabrics under extreme dark light conditions with exact same conditions，iPhone 11 needs to increase the ISO to 6400，Exposure time up to 1.1 seconds。The Xiaomi 11 Ultra has more light input advantages thanks to its super large bottom，Only 800iso and 1/2 second exposure time can capture a clearer picture than the iPhone 11，Even restored the original color。
It is worth mentioning that，Most phones will lose focus performance when the ambient light drops (for example, the above iPhone 11 seems to be lost in extreme dark light environments)。
The Xiaomi 11 Ultra benefits from the Samsung GN2's all-pixel omnidirectional octa-core focus，Each photosensitive pixel can be divided vertically into two diodes，Binocular focus for each pixel，Greatly improves focus performance。In addition, Xiaomi 11 Ultra uses multi-point ToF focus system for the first time，64 points of distance measurement to help accurately focus，The shooting experience is very good in extreme environments。
——Ultra-wide angle and telephoto。Not only the main camera material is so fierce that it is speechless，Xiaomi 11 Ultra's ultra-wide-angle and telephoto materials have also reached a "terrifying" level - all employees use Sony IMX586, a sensor that is still beautiful today，You should know that this year, some flagship models are still using sensors close to their specifications.，And here in Xiaomi 11 Ultra, it has become an ultra-wide-angle lens and a telephoto lens。
First look at the 48-megapixel IMX586 ultra-wide-angle lens，The field of view reaches 128° ，And it comes with strong resolution，Shooting the building、Scenes such as scenery can gain a broader and more shocking vision and composition。Al ultra-wide angle distortion correction，Can effectively improve the distortion effect of the edge of the picture，Make the film more natural。
Large-sole CMOS like IMX586 can be used in the periscope structure of Xiaomi 11 Ultra，It's really amazing。Looking at the current mobile phone industry，Only Xiaomi 10 Supreme Commemorative Edition and Samsung's previous generation super-large cup flagship Galaxy S20 Ultra adopt the same IMX586 solution。
On this basis, Xiaomi 11 Ultra achieves equivalent 10x optical zoom、120Digital zoom。

The "super big bottom" Samsung ISOCELL GN2 sensor exclusively owned by Xiaomi 11 Pro and Xiaomi 11 Ultra is not just a topical，And it has made the imaging capabilities of the two "Job Kings" of Xiaomi 11 series a considerable leap. The 1/1.12-inch giant's photosensitive area is about 60% larger than the IMX689 that has led for a long time.，Become the best mobile sensor area，Like a night vision device under dark light，Combined with dTOF, no burning has been lost from day to night。
Samsung GN2 sensor，Not only can you stand out in 2021，Even next year，I believe it's hard to see an opponent。The main camera sensor used by an ordinary flagship like IMX586 can only act as ultra-wide angle and telephoto on the Xiaomi 11 Ultra，Comprehensive field of view and image quality，Xiaomi 11 Ultra based on IMX586 has already reached the first echelon，And the IMX586 periscopic telephoto image with ultra-high pixel value，Strong analytical power displayed day and night，Almost stronger than all Qualcomm platforms' periscope telephoto models。
