Photography, as one of the main functions of mobile phones, has been paid more and more attention. From 1.2 million pixels in the Nokia era to 16 million pixels now, the imaging quality of mobile phones is developing at a visible speed. From the 13 million pixel IMX135 of Xiaomi 2S (32GB version) to the 516 million pixel IMX298 of Xiaomi now, how much improvement has Xiaomi mobile phone made in taking pictures over the years? Let's have a look.


Specifications

Among the four Xiaomi mobile phones, Xiaomi 2S (32GB version), Xiaomi 3, Xiaomi Note Standard Edition, and Xiaomi 5, Xiaomi Note Standard Edition can be regarded as a watershed. It was the first Xiaomi smart phone to use optical anti shake (Xiaomi 4 has no optical anti shake), but the flagship smart phone in the market at that time used IMX230 At the time of Sony's new generation of sensors, such as IMX234 and IMX240, the IMX214 of the standard version of the Xiaomi Note is aging. In the generation of Xiaomi 5, the camera of Xiaomi mobile phone can be said to be a complete change in hardware. Because the market has provided a mature solution, such as IMX298+Snapdragon 820, Xiaomi 5 also uses this combination, like many flagship models, and it is also equipped with four axis optical anti shake.


daytime

In the first group of daytime scenes, white balance: Xiaomi Note Standard Edition>Xiaomi 2S>Xiaomi 3>Xiaomi 5. In terms of analytical power, Xiaomi 5>Xiaomi Note Standard Edition>Xiaomi 3>Xiaomi 2S.


In this group of scenes, white balance: Xiaomi Note Standard Edition>Xiaomi 5>Xiaomi 2S>Xiaomi 3. In terms of analytical power, Xiaomi 5>Xiaomi Note Standard Edition>Xiaomi 3>Xiaomi 2S.


In this group of scenes, we noticed the sky beside the building. Due to overexposure, the standard version of Xiaomi Note can hardly see the clouds in the sky. In the font analysis in the distance, Xiaomi 5 still maintains its consistent advantages, rich details and high sharpness, which are the inherent advantages of IMX298 compared with other three.


In this group of scenes, the white balance of Xiaomi Note standard version is the most accurate, followed by Xiaomi 3, and finally Xiaomi 2S and Xiaomi 5. Although the white balance of the standard version of Xiaomi Note is the most realistic under high light, the lens also shows obvious glare, and the image of Xiaomi 2S seems to be covered with a layer of gray after being magnified.


In this group of potted plant samples, Xiaomi 3 showed obvious underexposure. The shooting time was about 11:30~12:00. At this time, the sun was strong, and Xiaomi 5 and Xiaomi Note did not show the standard performance, while Xiaomi 2S showed some overexposure. In terms of analytical power, Xiaomi 5 is still as good as other models.

In daytime photography, the analytical power of Xiaomi 5 has obvious advantages. It can be said that it is completely rolled. In addition, Xiaomi 5 has a high film forming rate. Focusing speed+focusing success rate is far higher than the other three machines. The only disadvantage is that the white balance of Xiaomi 5 is occasionally distorted.


at night

Here, Xiaomi 3 and Xiaomi 2S have large and obvious color noise, while Xiaomi 5 has no color noise, but also has many irregular noise points. Xiaomi Note has obvious smearing to reduce noise points, but doing so will cause loss of details of the proof.


In this group of scenes, several machines have always maintained their characteristics. Xiaomi 3 and Xiaomi 2S have a lot of color noise, the picture is pasted, and the standard version of Xiaomi Note is heavily smeared, and the details are lost. The particle noise of Xiaomi 5 is obvious, but it retains enough details.


The anti glare level of Xiaomi 5 is similar to that of Xiaomi Note standard version, while Xiaomi 3 and Xiaomi 2S are relatively poor, and there are obvious light spots in the picture. In this group of samples, except Xiaomi 5, the yield of the other three machines is very high Low.


In this group of coastal city scenes, due to the extremely complex light, how are the four mobile phones performing on the light? The white balance of Xiaomi 3 and Xiaomi 2S has obviously shifted. Except for Xiaomi 5, the edge details of the other three mobile phones are not rich enough, and the sharpness is also insufficient.



In the whole night shooting, Xiaomi 5's film rate, focusing, anti glare and analytical power are far more than those of the other three mobile phones. The biggest problem of Xiaomi Note Standard Edition, Xiaomi 3 and Xiaomi 2S is focusing and film rate. If these two factors are not considered, Xiaomi Note Standard Edition has stronger noise control than Xiaomi 3 and Xiaomi 2S, Although the details are lost after painting, the exchange is worthwhile.


summary

From the results, the photographic effects of Xiaomi 2S and Xiaomi 3 are very poor, not only because of the poor anti glare ability of the sample itself after imaging, many noise points, and insufficient analytical power, but also because their film forming rate is not high. In low light scenes, it is often necessary to take more than 10 photos to find a picture that is not blurred and has no problem focusing. There is also a big gap between the photography of Xiaomi 5 and the standard version of Xiaomi Note. This huge gap is not the improvement brought by the simple 4 million pixels. It can be seen that this is more about the optimization of algorithms. It's a clich é that Xiaomi 5 does not apply to all low light scenes. In general, from Xiaomi 2S to Xiaomi 5, the photography of Xiaomi flagship mobile phones has improved significantly. No matter which Xiaomi mobile phone users change to Xiaomi 5, they will feel a qualitative leap in photography.
