Computational photography technology enterprise

On the eve of Xiaomi 1 1 conference, Xiaomi mobile phone officially broke the news again: Xiaomi 1 1 will cancel its own charger and respond to the call of science and technology environmental protection!

When Weibo appeared, the first thing that was inevitable was the oncoming bristle.

But soon after the official news was released, there was a reversal message through a third-party blog:

The original charger will still be shipped with the mobile phone 1 instead of 1, but it will be packaged separately. You can choose+1 yuan GAN gallium nitride charger when purchasing, which is compact and environmentally friendly, and the charging speed is faster.

The specific news will wait until tomorrow's press conference (65438+09:30 on February 28th, 65438).

In addition to not sending chargers, tomorrow's conference will also include the following contents:

Briefly summarize the process of taking pictures: hardware (camera) receives light-software (processor) processes information-and finally the picture is presented on the screen. Manufacturers also optimize the imaging quality from both hardware and software;

Taking Huawei as the representative, the optimization direction focuses on hardware: Huawei gains advantages on the basis of imaging by exclusively customizing hardware such as camera sensors (for example, starting from P30, it exclusively customizes sensors with larger aperture to obtain more light, which is also the reason why Huawei's night shooting scene is invincible);

Represented by Google and Apple, the optimization direction focuses on software algorithms (this is the so-called computational photography): the same is computational photography, and the logic of optimizing software algorithms is different. Google pays more attention to using algorithms to weaken the disadvantages of mobile phone sensors, such as using algorithms to reduce image noise. Apple's approach is to identify the content in the picture through AI and optimize it in combination with the photo scene. For example, when shooting a backlit portrait, when Apple recognizes that the subject in the picture is a person, it will reduce the exposure of the background part, and then increase the exposure of the face part of the person to ensure that the light of the subject's face is normal and the background will not be overexposed.

Reason one:

Mobile phone cameras are limited by size and other reasons. The ceiling of hardware upgrade is actually very low. You can't be like a camera. The lens is heavier than the fuselage. The limitation of computational photography lies in the processor and algorithm. Compared with the former, the ceiling of computational photography is much higher.

Reason two:

Computational photography requires very high processor computing and AI performance. Xiaomi 1 1 is equipped with a new generation of Snapdragon 888 processor, which, combined with powerful AI performance, can process image information faster and achieve better computational photography.

I think Xiaomi's computational photography should optimize the scene like Apple's, because the basic imaging quality of most flagship mobile phones on the market is already excellent, and it is more necessary to optimize the picture of specific content for specific scenes. I hope that Xiaomi can make some new computational photography content while imitating Apple, which may open up a new direction of computational photography.

This also means that the focus of this camera upgrade will be video recording.

With the title of "Music Mobile Phone" of Xiaomi 10pro, I believe the sound quality of Xiaomi 1 1 will not disappoint people.

At present, there are two aspects to determine the update content of MIUI 12.5:
