Xiaomi 8 super night scene experience: MIX 3 has the same algorithm blessing, which can be improved at a glance.

Although the IT 168 evaluation uses the imaging hardware consistent with Xiaomi 8, thanks to the continuous innovation of the algorithm, especially the introduction of the super night scene mode, Xiaomi MIX 3 has been improved again in taking pictures. DxOMark's still photography score exceeds 108, ranking third in the world in total score, which is the best result achieved by Xiaomi.

Lei Jun also said at the first time after the release of Xiaomi MIX 3 that engineers had been urgently asked to transplant the corresponding algorithm to Xiaomi 8. Please be patient.

Now this promise has been fulfilled. In the latest MIUI 10 stable version update of Xiaomi 8 series, the camera algorithm of MIX 3 is perfectly transplanted, and two practical functions of hand-held super night scene and 960fps slow-motion photography are added, which makes the imaging level of Xiaomi 8 move to a new height and the camera playability is upgraded again.

We also upgraded Xiaomi 8 in our hands for the first time and experienced it and shared it with everyone.

Holding a super night view, the promotion can be seen at a glance.

Because the camera module of mobile phone is small, the sensor size and aperture size are inherent disadvantages. It is a feasible scheme to get enough exposure and extend the exposure time in the low brightness environment at night. But the problem is that long-term exposure requires high stability of hand-held shooting. If there is no auxiliary equipment such as "iron hand" or tripod, there is a great possibility of sticking film.

The super night view of Xiaomi provides a new way to solve the problem. When we press the shutter, the mobile phone will continuously take multiple frames of photos with different exposure parameters, and then screen out the most accurate parts of each frame for superposition and synthesis, showing clear and bright night photos.

This sounds easy, but it is technically difficult to achieve. Due to the continuous shooting of multiple photos, image offset and blur caused by hand shake are inevitable. If it can't be handled correctly in the synthesis, it will directly affect the shooting effect, and there will be problems such as smear and blur.

In order to solve this problem, Xiaomi introduced the AI algorithm, intelligently selected 100 key feature points from each frame of photos for identification and comparison, aligned the images through the feature points, corrected the object offset, and filtered the fuzzy parts, which laid a good foundation for the final film.

So in the super night scene mode, what is the actual night shooting performance of Xiaomi 8? Let's compare it with the sample below. (Above: shooting in normal mode, below: shooting in super night mode)

In this set of proofs, the brightness of Xiaomi 8' s picture has obviously improved after turning on the night scene mode, but the bulletin board on the left side of the picture shows no signs of overexposure, and the text edges are clearer and sharper, and the colors are richer and more complete.

In the comparison of this group of proofs, the overall exposure control of the proofs in night mode is better, showing more dark details, such as advertisements on fences and windows.

In the comparison of this group of building samples, it is difficult to distinguish the outline of the building from the samples taken by ordinary people, and the flag at the top is seriously overexposed, so it is difficult to see the color clearly. In the night scene mode, the overall brightness of the picture is improved, the colors of buildings and flags are preserved, and the noise of the night sky is also suppressed, and the advantages are clear at a glance.

Finally, in the comparison of this group of proofs, the highlight suppression in night scene mode is actually better than that in conventional mode with conservative exposure strategy, and it also provides more details, such as trees, shops and roads in the upper left corner.

By comparison, the results are basically clear at a glance. In the hand-held super night scene mode, the night shooting level of Xiaomi 8 is improved again, and the night can be perfectly fixed in a few seconds, which lowers the threshold for taking excellent night photos.

960fps slow motion, creating the illusion of solidification

In addition to the super night scene, Xiaomi 8 has also added a 960fps slow-motion photography function, which is suitable for recording moving objects or fleeting moments.

A few short films were simply recorded, and the ordinary picture instantly had the illusion of time "solidification". Clever use can easily create a sense of sight for large films. At the same time, Xiaomi 8 can automatically analyze the video shooting content and match the background music, and support instant sharing to social media, which is more playable.

abstract

Xiaomi's investment in taking pictures this year is obvious and the effect is immediate. Implemented on Xiaomi 8, with the maturity of hardware and the blessing of MIX 3 algorithm, Xiaomi 8' s camera function has been "reborn" and has the best imaging performance in the price range of 2500 yuan, which can be said to be full of sincerity.
