iPhone X、Note 8、Mate 10 Pro、Pixel 2 XL， It is the four mobile phones with the highest photo taking scores from the French image evaluation agency DxOMark. Each of them has many fans, and they don't give in to each other. This time, we use live photos to compete.

Parameters and description
Among them, except for the single shot Pixel 2 XL, all machines have "dual optical anti shake"; Note 8 and Pixel 2 XL use the same level sensor. This time, Note 8 is N950F, and the sensor is S5K2L2; Mate 10 has the largest aperture. The subphoto is a wide-angle subphoto with 20 million pixels. After digital cutting and interpolation, the discrimination will be better than that of telephoto optics; The main camera of iPhone X seems to have the weakest parameters, but Apple said that the sensor color filter and pixel details have been improved and are the only support 4K@60fps Of.
Investigation items and scales
The main assessment points of mobile phone photography effect include:
White balance and photometry In many scenes such as sunlight/light/weak light and extremely weak light, whether the white balance (picture color and wind direction) and brightness can be close to the naked eye;
Tolerance , that is, the ability to show the details of light and dark at the same time. For mobile phones, this is basically equivalent to the HDR effect, including the size of the processing force, whether the processing is natural and harmonious, whether there is ghost after synthesis, white balance deviation and the decline of discrimination;
Discriminative power Roughness can be understood as clarity, and the sharpness, detail and naturalness of the picture must be taken into account at the same time;
The remaining assessment contents include noise control, color saturation (the industry trend is changing from "realistic" to "eye pleasing"), lens quality (including edge degradation control, anti glare, fog control, wide-angle and pillow distortion control, etc.), and many other contents.
For different users, the proportion of different items in the imaging part is completely different. The Maoist Party, who likes to zoom in and scan, will definitely put discrimination first, and the proportion is high; The party in the circle of friends attaches great importance to tolerance, white balance, saturation and other items, but the requirement of discrimination is not high. Everyone should line up and down according to their own ruler.

Backlight scene 3, only Pixel 2 XL shows rich dark details close to the naked eye
The backlight scene 3 is magnified in the center, and the details at the light source are the traditional strengths of Pixel 2 XL
Light scene
The anti glare ability of the lens is relatively weak in Pixel 2 XL and Note 8. Of course, this is a fight between immortals. On the whole, they are among the best in anti glare ability.
Light Scene 1
Zoom in at the center of light scene 1 (the painting of Mate10 has erased the details on the fire hydrant, but the outline is really the clearest and sharpest, which is a trade-off)
Light Scene 2
Light scene 2 is magnified in the center (Pixel 2 XL is lightly smeared, with heavy noise, and the edges are not clear enough, but the details are reserved at most, which is most natural)
Light scene 2 center right zoom in
Light Scene 3
Light scene 3 is magnified in the center (Pixel remains the strongest detail in highlights, Mate 10 is also good, but it is color biased again)

summary
Photo ranking
This contrast test is mainly aimed at the main camera. The final ranking result is very close to DxOMark. Of course, the Mate 10 Pro on DxOMark is not Mate 10, and their imaging styles are different.
In fact, the main shots of iPhone X, Note 8 and Mate 10 are all the same, with a small gap. In particular, Note 8 and Mate 10 of S5K2L2 are very similar in their main photographic performance. However, if you consider the upper and lower photos, Note 8 and iPhone X will be difficult to distinguish. The Pixel 2 XL's tolerance highlight performance is amazing, but the rest of its performance lags far behind the other three:
iPhone X： The performance is balanced, the white balance is the most stable, and there is no shortage of the previous generation of light metering. After the HDR algorithm is triggered, the highlight detail is the closest to Pixel (although far from it). The weak light noise control is OK, and the balance of "nature/detail and picture purity" is the best. It has good subjective discrimination, and extremely weak light also has good detail performance. The main weakness is that the HDR algorithm has a high trigger threshold. Compared with Note8, the subphoto is far behind in discrimination and noise control, but stronger than Mate10's subphoto.
Note8（N950F，8895+S5K2L2）： There is no doubt that it is the strongest sub camera. The main shooting feature is the heaviest sharpening algorithm among the four, with a tolerance between iPhone X and Mate 10 (but in fact, HDR has a high trigger probability, and many light scenes will beat iPhone X in highlights). The smudging algorithm is excellent. The white balance stability is only inferior to iPhone X, and the weak light metering is slightly brighter, but the extremely weak light discrimination is weaker than iPhone X and Mate 10, and the results are unexpected.
Mate 10： The success rate of focusing is the lowest among the four sets. The number of wasted pieces lost due to focusing is the largest among the four sets, and it is also the one with the most drifting white balance. The indoor fluorescent lamp is red. The metering is slightly brighter, and the white balance stability of the 4 sets is the worst. In many scenes, only the white balance of the 4 sets has the biggest difference. The tolerance is average, with the trace of raising the contrast, and the dark details are easy to die. The picture has obvious smearing and sharpening, excellent noise suppression, less detail loss, and the overall style is very close to Note8.
Pixel 2 XL： The details of the picture and the tolerance of light and shade are incomparably strong, leaving other competitors several streets away. However, the sharpening and smearing algorithms are very light, although sometimes they may cause the illusion of not focusing on the camera. The discrimination power is the weakest among the four sets, and the noise is also very obvious. The weaknesses and strengths are very prominent, and the comprehensive performance is significantly weaker than that of the other three flagship ships.
