Huawei P50 Pro image specifications：Black and white rear camera + high-pixel telephoto multi-photo synthesis Calculation photography show operation
Since the official has not yet announced the specific parameters of the camera sensor，We can only use the EXIF information on the photos，Let's speculate on the specific specifications of Huawei P50 Pro main camera CMOS。
Huawei P50 Pro's wide-angle lens，1200CMOS，The equivalent focal length is 13mm，Physical focal length is 1.76mm，The conversion coefficient is approximately 7.39，The size of a single element is approximately 1.17μm，CMOS size is 1/2.73″about。
main camera，5000CMOS，Equivalent focal length 23mm，Physical focal length 5.54mm，The conversion coefficient is approximately 4.15，The size of a single element is approximately 1.01μm，CMOS size is 1/1.6″about。
Black and white rear camera，4000CMOS，Equivalent focal length 26mm，Physical focal length 5.56mm，Conversion coefficient 4.86，The unit element is about 1μm。
telephoto lens，6400CMOS，Equivalent focal length 90mm，Physical focal length 16.85，The conversion coefficient is 5.34，Unit element is about 0.73μm，CMOS size is 1/1.97″about。
Combined with known resolutions，and estimated CMOS size information，It's not difficult to guess the rear camera specifications of Huawei P50 Pro。
Main camera 50 million pixels，1Single element size around μm，IMX is likely to be used 766，The telephoto is GW3、One of OV64B etc.。 The black and white lens is very similar to the specifications of the IMX 600，The wide-angle lens is probably OV13B10, etc.。
Judging from the optical hardware specifications of the rear camera，The Huawei P50 Pro's rear camera module is not the strongest in history。 Like the RYYB ultrasound perceived post-photographer that emerged in the previous two generations，Even the stunning 10x optical zoom that was not available last year。
Although the hardware specifications are not as good as the maximum，However, this generation of Huawei P50 Pro uses the most mature optical module to train。 This year's Huawei P50 Pro's breakthrough in imaging is not hardware，Instead, it is equipped with this new XD Optics computing optical system。
——XD Optics Computational Optics
well known，No matter how powerful the specifications of the rear camera CMOS are，The optical system it is always used to drag down mobile phone images。 Due to limited space，Mobile phones are basically out of reach for high-quality lenses，The natural phase difference loss of lens module is inevitable。
Even now, computing photography is very popular，It can make up for the optical shortcomings to a certain extent，However, ordinary manufacturers only use multiple exposure + multi-frame synthesis，to adjust the details of the final imaging、Brightness and color。
Halo、Color cast、Ghost shadow、Flaws in optical systems such as noise cannot be compensated by the algorithm，This also makes the final film always regretful。
And the XD Optics Computational Optics proposed by Huawei，It is to optimize the optical system of the mobile phone in a targeted manner.。
It will first confirm the distortion caused by light passing through each lens，Then, the image is subject to targeted algorithm correction，This can greatly avoid the phone's optical system from dragging the back legs of the entire image module.，Algorithm to remove glare、Optical defects such as ghosts，Greatly increase the effective data volume of the original image。
After replenishing the details of the original image with the help of computational optical reverse，It's the familiar image processing stage。
Brand new XD Fusion Image Engine，Optimize the brightness of the film、color，even content-specific enhancement details、Feelings of layers, etc.，And use black and white post-photographs to collect light and dark information、And Huawei's new primary color filter engine，The films are in line with the effect of the real world, whether they are in color or light or dark.，Do to another extent”what you see is what you get”。
Let's take a look at a practical demonstration of XD Optics computing optics on Huawei P50 Pro，Night photography of the scene with a big light ratio + digital zoom，It's almost impossible to take pictures for flagship phones，However, Huawei P50 Pro is not affected at all。
Our past understanding of computational photography，Probably just adjusting the brightness，Contrast，Just erase the noise。 XD Optics' computing optics is more in-depth in processing photos，Can be called turning decay into magic。
in pro mode，Unprocessed images are more in line with our traditional cognition。 Night shooting + digital zoom，The highlight part will explode directly when the ISO is full，The overall picture is very good, both in noise and in quality。
And under the processing of the new XD Fusion image engine，Not just the brightness of the surface、Color adjustment、Further image details will also be supplemented with the help of the AI engine，Reconstruct the picture in layers。
The previous second you were still staring at the big mosaic，The high-definition original image will be presented in front of you in the next second。The processed pictures are no different from what the naked eye sees，It's no exaggeration to say that XD Optics repainted a picture of the same scene based on the original image。
——Super filter system
When taking photos on a daily basis，Black and white lenses are also playing a role all the time as part of XD Optics’ computing optics。 This is not the first time that the black and white camera with the main camera level is available.，Previously, it has been unveiled on Huawei P9。 This time, the black and white rear camera of Huawei P50 Pro has a large bottom + large pixels + large aperture support.，More light inlet，The final result will be better。
Black and white rear cameras will not be able to independently image，Instead, it will use the light and dark data it collects，Supplement information about the main film。 The final effect is not simply to brighten。
For example, when taking pictures during the day，Improving the brightness of the picture building、While brightness is also reduced, the brightness of green plants is reduced，Make it more in line with the dark green view seen by the naked eye。And at night，Black and white lenses are responsible for increasing the amount of light input，So we can also see that the photos involved in the synthesis will have richer dark details.。
——Original Color Engine
Thanks to the use of black and white rear camera assistance to increase the light inlet，The main camera also uses a more mature RGGB color filter with algorithms，Huawei P50 Pro has made qualitative improvements in the precise color reduction of imaging。
white balance、color temperature、Accurate restoration of multiple parameters of color，Can greatly change the past, take photos with your phone，Especially in night view mode”Too strong”Current status，The film will look more realistic。
Under extremely dark light conditions，Take photos with standard color cards，We can horizontally see the precise record of Huawei P50 Pro。
When shooting，Background with red light interference，This tests the evaluation of content by the mobile phone imaging algorithm。The first phone with super large bottom main camera was hit，It's obviously reddish in the film，Almost all light-colored blocks have been affected to some extent。iPhone is an old problem，White balance tends to be absolute white balance，Correct the 6500K warm light into absolute white light，Remedy in cold。
Huawei ensures white balance、color temperature、The accuracy of color，In horizontal comparison，Huawei P50 Pro is processed after night view algorithm，The closest picture”Original flavor”Mobile phone，This is enough to show the role of this generation of original color engine。
XD Optics Computational Optics is the first concept proposed in Huawei P50 Pro，It is also on Huawei P50 Pro，Huawei has implemented it for the first time”Full-domain”Image information recovery system。
Perhaps the rear camera hardware stacking of Huawei P50 Pro is not the strongest ever，But its computational photography has reached a new level。 Whether it is the restoration of image details，Post-optimization processing，Even the precise recording of colors was much beyond our expectations at the time。
Today, Huawei P50 Pro has officially left the competition track for mobile phone rear camera hardware inward roll，A new charter for all-domain computing photography has been opened。 Relying on algorithms to counterattack the "big bottom"，It also shows that mobile photography is a systematic project，Suitable hardware matching、Excellent algorithm training is indispensable，It is definitely not a "super bottom" or a hardware gimmick with N main camera that can determine the final performance.。
