The technology is limited, the image is blurry, and it can freeze the action

1. The status quo and limitations of mobile phone imaging technology

When shooting with a mobile phone every day, you often need to hold the phone steady, otherwise the photo may be blurred. However, when trying to photograph fast-moving objects, even when the hand is very steady, the photo still appears blurry, due to the technical limitations of traditional mobile photography. When taking a photo, the moment the shutter opens actually has a duration, which can be a few tenths of a second in a dark environment and a few thousandths of a second outdoors in good light. While such exposure times are sufficient to capture stationary or slow-moving objects, they are not short enough for objects moving at high speeds. For example, if the shutter speed is 1/1000th of a second, the car has advanced about 8.3 centimeters during the shutter opening. This movement can create a dynamic blur effect in video that enhances the sense of speed, but in still photos, it can lead to blurring.

2. Analysis of the principle of Huawei Pura 70 series "ultra-high-speed wind gallop flash shooting".

Let's talk about Huawei's new phone's "ultra-high-speed wind speed" function. Did you know that this is a big breakthrough in the field of mobile phone imaging?

It is very difficult for traditional mobile phones to capture high-speed moving objects. After all, no matter how high the shutter speed is, it is only a few thousandths of a second, and fast-moving things are bound to shoot paste. For example, if you ride a shared bicycle and rub it next to it, you can see what shape the bicycle is?

However, Huawei's new machine's "ultra-high-speed wind gallop flash shooting" function solves this problem. At its core, the "short exposure" technique is at its core. If you think, if the exposure time is shorter, the picture will be much clearer. The problem is that short exposure will underexpose, and the image quality is too poor.

So Huawei played a clever trick and took a "long exposure" photo at the same time to ensure the image quality, and then through the AI algorithm, the two photos were perfectly fused, combining the good image quality of long exposure photos with the clear dynamics of short exposure photos. This is amazing, the dynamic is clear, the picture quality is guaranteed, killing two birds with one stone!

AI algorithms alone are not enough, and hardware conditions are also critical. Huawei's new device uses the industry's largest physical aperture, which allows more light to enter the lens. As we all know, to increase the shutter speed, you have to open the aperture wide to get enough light in. Therefore, Huawei's new machine can achieve "ultra-short exposure", relying on this super large aperture.

There is also an XD Motion engine, which intelligently recognizes moving objects in the frame and only shoots with a "short exposure" for moving parts and a "long exposure" for still parts. This maximizes the overall clarity and quality of the picture.

Through the "short exposure" technology to capture dynamic details, "long exposure" to ensure the overall quality, coupled with a large physical aperture and intelligent motion recognition, Huawei's new machine has achieved a big leap in the field of mobile phone imaging, worthy of the image flaghship! Are you interested in this new technology?

Okay, let's continue to talk about the actual performance of Huawei's "ultra-high-speed wind gallop flash shooting" function.

Judging from some of the samples released by the official, I was really amazed! For example, when I photographed the badminton player Chen Yufei's racket, not only did I capture the racket and the ball clearly, but even the expression on her face was not blurred. Looking at a high-speed train with a speed of 300 kilometers per hour, the body windows are so neatly photographed, and the score is exactly the same.

You must know that in the past, when we used our mobile phones to shoot such fast-moving objects, we either simply took pictures of a mess, or we could only faintly see an outline. Through the "ultra-high-speed wind gallop flash shooting", the picture is so clear and realistic, and the details are not distorted, which has really reached a new height!

But this is just a small case, and what is really powerful is its power when applied to more fields. For example, it is possible to shoot objects such as children and pets whose trajectory cannot be predicted, or outdoor sports and racing competitions that require very high shutter speeds. What used to be impossible to capture with a mobile phone is no longer a problem with this new feature.

I was actually quite disappointed with the camera experience on my phone. Obviously, the pixels are getting higher and higher, but they can't capture wonderful moments, and the detail processing is also very average. But with the "ultra-high-speed wind speed flash shooting", the mobile phone finally broke the traditional limitations and officially entered a new era of shooting.

So the question is, can there be further breakthroughs in this technology in the future? I think it is very possible!

The technology of image sensors is constantly improving, and if there is a corresponding ultra-high sensitivity sensor with a large bottom in the future, it will further broaden the limit of "short exposure". Secondly, the AI intelligent algorithm will continue to be optimized, the integration of "long and short exposure" will be more natural and perfect, and the quality of detail processing will also be raised to a new level.

At present, the multi-lens and multi-camera systems on mobile phones are not well utilized, and if the multi-lens can work together to carry out "split exposure fusion", the amplitude will definitely be even higher.

It's not enough to rely on theoretical speculation, let's wait and see what kind of brilliant works Huawei and the entire industry will have in the future in terms of image innovation.
