In the photo circle，As the saying goes, a big one can crush someone to death.。Since the emergence of a Samsung HMX at the end of 2019,，Mobile phone photography has officially entered the rhythm of the outsole competition，CMOS outsole from 1/1.43” to even 1/1.28” emerges in endlessly，It doesn't seem like it will take long，Mobile phones will catch up with card machines。But no one expected，This moment came so quickly。2021February 23，The new sensor ISOCELL GN2 released by Samsung has officially taken the final step to hit the 1-inch mobile phone market.，And launched by Xiaomi 11 Pro。
This new sensor has an area of up to 1/1.12”，Compared with the existing mainstream small-bottom sensor, the area has even increased by more than twice.。5000CMOS，Supports more advanced Daul Pixel Pro focusing，After the pixels are four-in-one, the single pixel size is as high as 2.8μm.，The hardware gap between phones and cameras has never been smaller。Supplemented by the camera algorithm of mobile phone manufacturers，can only say，The era when mobile phones will replace card machines may really be coming。
In addition to the advanced main camera，Xiaomi 11 Pro also brings many other breakthrough improvements。First is the battery，Upgrade to silicon anode battery，In the case of a single core, it achieves a capacity of 5000mAh and a charging speed of up to 67W.。
In terms of heat dissipation，Xiaomi 11 Pro adopts a solid-liquid-gas three-dimensional cooling system，Based on the original VC liquid cooling + graphite + copper foil，Added phase change cooling pad。When the processor is working，The cooling pad absorbs heat and liquefies it，The heat can be efficiently exported to the VC and then dissipated at the cold end.，This ensures that the performance of the Snapdragon 888 chip is at full capacity while the temperature is not too high.。
also，The audio specifications of Xiaomi Mi 11 Pro are also further improved，The dual speakers use newly customized 1014 speaker units，Professionally tuned by Harman Kardon and built-in scene recognition，Guaranteed to adapt to different sound sources and scenes，Can provide the most matching music effect。
next，Let us experience Xiaomi 11 Pro together，Let’s take a look at how strong the super-soled GN2 is。
Exterior：In the same vein as Xiaomi Mi 11, the back cover CMF has a more textured feel.
The appearance design of Xiaomi Mi 11 Pro is basically the same as Xiaomi Mi 11。The front is slightly curved.，Perforated front camera in the upper left corner。The back is also similar in style to Xiaomi Mi 11，Wide-angle lens remains unchanged，In addition to stuffing an oversized GN2 main camera，Also added a 5x periscope telephoto lens。The rear periscope module is very small，Specifications are similar to those previously seen on Xiaomi Mi 10 Youth Edition。GN2 main camera with super large bottom，This can be seen from the lens area。
interface，Up and down dual speakers，Has Harman Kardon certification。There is an ancestral infrared remote control module on the top。The rest is the microphone opening and SIM card slot。

three、After-shot analysis：How strong is the nearly 1-inch GN2?
- main camera
This time Xiaomi 11 Pro brings us the largest sensor in the history of mobile phones, Samsung GN2，Definitely the top priority。
Its size reaches an astonishing 1/1.12 inches，In one fell swoop, it set a new record for the lowest level in the mobile phone industry.。If you don’t have an intuitive feeling about this number，Let's compare。
GN2 is currently the world’s largest mobile phone image sensor，Its area is 1.4 times that of the HMX used by Xiaomi’s previous generation，It is 1.37 times that of the previous game in the same series, GN1.，1.63 times that of the IMX 689, which is famous for its focus。Even last year, two models, IMX 700 and OV48C, set new records for the largest bottom.，GN2 also reached 1.3 times and 1.35 times their size respectively。
In the face of Apple, which has been sticking to its bottom line,，The area comparison between GN2 and it is even more disparate。Even if the iPhone has adopted a 1/1.8" "larger bottom" 12 Pro Max，The area of GN2 has also reached 2.5 times that of its rear camera.。
With the support of the outsole，GN2 has 50 million pixels，This gives it a single large pixel area of up to 1.4μm，After four-in-one pixels, it is possible to achieve a single pixel of 2.8μm.，Can provide better dark imaging effects and higher dynamic range，It avoids the unit pixel being too small due to large base and high pixels like HMX.，On the contrary, the result of imaging is general。
In addition to the inherent advantages brought by the oversized sole,，GN2 also brings two new features，Dual Pixel Pro and Smart ISO Pro。
1、 Dual Pixel Pro：On the previous GN1，Samsung adopts a full-pixel dual-core PD focusing solution，Each pixel is divided vertically into two parts，Under one lens are two photodiodes on the left and right，When focusing，GN1 will switch the left and right photodiodes，Use the phase difference of the image to determine whether the focus is successful，This enables full-pixel fast focusing capabilities，Focus speed can reach up to 0.3s。
Full-pixel dual-core focusing is fast，But it also has its weaknesses。Horizontally arranged sub-pixels are very sensitive to phase changes in the vertical direction，But it also means，Phase focusing in the horizontal direction will become difficult，Once you encounter a special scene，For example, large areas of parallel horizontal stripes，Focusing may not be as fast and accurate as it once was。
To solve this problem，The new Dual Pixel Pro is here。
Dual Pixel Pro brings a new way of cutting，Unlike in the past, pixels were divided vertically in the center，on GN2，Green pixels are cut diagonally at ±45°，This allows them to distinguish vertical phase differences while，Also given the ability to resolve lateral phase differences。
When encountering vertical patterns，GN2 will still use the traditional dual-core focusing method，45°The left and right long sides of the division will participate in the work，Identify phase difference and complete focusing。When encountering horizontal patterns that are tricky with traditional arrangements，Only these 45° oblique green pixels will play a role。The diodes on the upper and lower long sides will work，Utilize the upper and lower phase difference，Even horizontal patterns quickly capture focus。
Through this special operation of 45° oblique cutting of green pixels，Dual Pixel Pro can handle vertical patterns，Still exerting 100% of the original full-pixel dual-core focusing performance。And when faced with horizontal patterns，Although only 50% of the pixels will participate in dual-core focusing，But it’s also faster than the original arrangement，and more accurate。
but，Let’s talk about focus performance，Samsung’s Dual Pixel Pro is still no match for Sony’s 2×2 OCL。the reason is simple，Samsung’s process uses a combination of small pixels and small lenses，And 2×2 OCL is the real four-in-one large pixel mode。On the one hand, quantum efficiency has certain disadvantages，On the other hand, 2×2 OCL allows all pixels to participate in all-round focusing and imaging.。Dual Pixel Pro has improved focus performance，But still not the strongest。
2、Smart ISO Pro：GN2 supports Smart ISO，Can automatically select the appropriate ISO value for shooting in different scenes during the day and night，And what's special is，It also supports Smart ISO Pro function，You can set the highest ISO and lowest ISO of the scene，Shoot images with two ISOs at the same time，and synthesized through multiple frames，Give images a higher dynamic range，The final result is a photo with rich highlight details.，Finished product with less noise in dark areas。
——Rear camera module specifications
That’s it, the main photographer，Let’s talk about the rear camera system of Xiaomi 11 Pro。In addition to the amazing GN2，Xiaomi 11 Pro is also equipped with a wide-angle lens and a periscope telephoto lens.。
The wide-angle model is consistent with Xiaomi Mi 11，for OV13B10，With 13 million pixels and 123° field of view；The periscope telephoto lens is OV08A10，It is the same periscope telephoto model that is equipped with Xiaomi Mi 10 Youth Edition.，Pixels are 8 million。
simply put，In the rear camera system of Xiaomi 11 Pro，Compared to GN2, the main camera that has reached the top，The other two sub-photographers are very different from them.，Seems unbalanced，So when using the secondary camera，There will be some differences in imaging quality。
Especially when I chose the 5x periscope lens，This will cause certain gaps in the focal length continuity of Xiaomi Mi 11 Pro.。After all, even the 100-megapixel Xiaomi Mi 10 Pro，Both use a 2x portrait lens and a 3.7x fixed focus lens to achieve zoom relay.，It is difficult for Xiaomi Mi 11 Pro to perfectly fill the focal length between 1 and 5 times through digital zoom.。
It can be said，Xiaomi Mi 11 Pro is an imaging flagship featuring GN2 main camera，As for the assistant photographer，Their role is only to supplement some special cases。
