Its super “super-high-speed flash shooting” ability can clearly freeze whether it is capturing a flying pet or the expression of a person on a roller coaster. In addition, it also supports capturing racing cars or racing cars at speeds up to 300km/h. The maglev train is truly the “king of snapshots”.
Why can Huawei Pura 70 Ultra achieve such a sophisticated design? Today we will reveal in depth how an ultra-thin 1-inch mobile phone is made.
Super light-concentrating retractable camera, perfect balance between 1-inch and thin body
In recent years, imaging technology has achieved rapid development in the field of mobile phones. 1-inch outsole sensors have become the focus of competition among major mobile phone manufacturers. Many mobile phone brands have launched flagship mobile phones equipped with 1-inch outsole sensors.
Although the image quality has been significantly improved, the price is also quite heavy. The larger the sensor of a mobile phone, the longer the physical focal length required, and the thickness of the lens will increase accordingly. Currently, the lens thickness of 1-inch mobile phones is generally around 15mm.
You know, the thickness of the mobile phone body is generally around 8 or 9mm, which means that the lens is 60% thicker than the mobile phone, which greatly affects both the look and feel.
Faced with the contradiction between cameras that continue to grow taller and limited body space, how did the industry solve it before?
For example, Xiaomi demonstrated a retractable large-aperture lens in 2020. In addition to being retractable, its ultra-large aperture can increase the amount of light entering by 300%. But it is a pity that now, 4 years later, it is still not applied on Xiaomi mobile phones.
OPPO also demonstrated a pop-up telescopic lens in 2021, which can also be raised and lowered. In normal state, it is a wide-angle main camera lens. When raised, it becomes a portrait lens with an equivalent focal length of 50mm, which is equivalent to a combination of wide-angle and telephoto. . However, OPPO has yet to release a mass-produced model equipped with this technology.
It can be seen that various companies have researched telescopic lenses, but how to mass-produce them is a very difficult problem. On the one hand, to achieve telescopicity, a mechanical structure is indispensable, so the mobile phone may become thick and heavy; on the other hand, if a telescopic structure is used, dustproofing and waterproofing are another big problem.
Faced with the difficulty of mass production of telescopic lenses, how does Huawei Pura 70 Ultra achieve mass production of super-concentrated telescopic main cameras?
As can be seen from the recent disassembly videos of some bloggers, Huawei Pura 70 Ultra uses a unique rotating telescopic lens structure, which is powered by a compact, small-sized, high-speed, and powerful motor to drive the planetary gear set. Rotate to achieve automatic expansion and contraction of the lens, and also provide more vertical space for the lens.
When taking pictures, the lens will automatically rise to achieve perfect picture quality; and after quitting taking pictures, the lens will automatically lower to maintain the overall lightness and thinness, achieving the effect of killing two birds with one stone.
The greater amount of light input combined with the original XD Motion motion engine makes the “super-fast flash shooting” well-deserved.
To achieve the ultra-fast flash shooting of Huawei Pura 70 Ultra, hardware innovation alone is not enough.
For users, there has always been a need to take pictures of fast-moving objects, and Huawei is not the first mobile phone to do “flash photography”. However, previous “flash shots” were limited by hardware and algorithms, which placed great restrictions on the speed of objects. High-speed moving objects would still be unable to be captured. Like Huawei, which can do flash photography at a speed of 300 kilometers per hour, no other company can do this. And such a powerful capturing ability is not obtained by giving up image quality.
Photography is the art of using light. To achieve a snapshot, the traditional approach is to increase the shutter speed. But the problem is that for the smaller sensor size and aperture of mobile phones, if you increase the shutter speed while ensuring that you can take a picture, the ISO will be raised very high, which will lead to poor image quality and full of noise and smear.
In order to take into account both the ability to take good shots and the best shots, Huawei Pura 70 Ultra uses a 1-inch outsole sensor and a unique rotary telescopic lens design that can automatically extend the lens during photography, creating a unique experience in a body that is only 8.4mm thick. It provides a larger internal space and effective lens height, and the large aperture of F/1.6 brings a greater amount of light into the main camera. The increase in the amount of light entering means that the sensor can capture more light per unit time. When the shutter time is shortened and the ISO does not need to be set very high, excellent image quality can still be obtained. This feature is useful for capturing clear images in fast-moving scenes. Images are crucial.
Based on this powerful main camera, Huawei Pura 70 Ultra also introduces the XD Fusion Pro motion engine that supports instant double exposure function in order to further optimize the image quality.
In daily shooting environments, some places are usually bright and some are dark. In order to obtain photos with normal exposure and avoid dark parts being too dark and bright parts being too bright, we usually continuously shoot two frames of different lengths and then fuse them. Achieve perfect filming. However, the shooting characteristics of the two frames before and after are seriously unfavorable for post-production fusion for high-speed capture.
The instant double exposure function of Huawei's XD Fusion Pro motion engine can capture long and short frames at the same time, recording the momentary details of motion through short exposures, while long exposures retain rich background information and image quality. Then, through AI motion vector calculation, the pictures captured by long and short exposures are matched with local features, thereby reducing local motion blur, and finally generating high-definition motion moment images.
As a result, the powerful imaging hardware + imaging system finally created the ultra-high-speed flash shooting function that has amazed countless users.
In fact, the peak imaging experience that Huawei Pura 70 Ultra brings to users is not limited to the retractable main camera. It is also equipped with a new super-concentrating macro telephoto camera, equipped with a periscope telephoto with an aperture of F2.1. It brings super light-gathering ability and better telephoto image quality, and the telephoto lens also supports the “ultra-fast flash shooting” function, making it more convenient for users to shoot long-distance and high-speed moving objects, such as flying objects. Birds in the middle. The telephoto macro camera also supports a 5cm focusing distance and 35x macro zoom, allowing users to change their microscopic perspective and rediscover the mystery of life through the lens.
In addition, Huawei Pura 70 Ultra has also comprehensively upgraded the portrait photography function. Starting from the perspective of realism, whether it is a front-facing selfie or a rear-facing recording, it can be more realistic and delicate. The portrait blur is clearly layered, easily helping users capture natural-looking skin tones. , high-quality films with delicate skin texture and moving light and shadow.
It can be said that Huawei Pura 70 Ultra relies on its ultimate imaging technology and innovation capabilities to push the imaging capabilities of mobile phones to the extreme, allowing users to easily leave unforgettable memories and enjoy the fun brought by technology.
The exquisite rubber ring and lens are designed to perfectly achieve IP68 dustproof and waterproof
Faced with the problem of mechanical structure reliability, how does Huawei Pura 70 Ultra solve it?
Many years ago, pop-up front cameras were popular in smartphones, but they quickly disappeared.
This is because, in addition to the advantages of “showing off skills”, its disadvantages are more obvious. The biggest problem is that the waterproof performance is too poor. The lift-type mobile phones at that time had a large gap to place the front camera, and the waterproof effect was naturally not as good as that of ordinary mobile phones. cell phone.
In addition, accidentally raising the front camera module may cause damage or bending, making repairs more troublesome.
Taking pictures is a high-frequency function of mobile phones that is used almost every day. Huawei has put a lot of effort into the reliability of this retractable camera. The interior of its structure is made of high-strength, high-toughness materials to create an ultra-reliable buffer protection structure, which has passed 300,000 lens telescopic tests.
Not only that, in order to ensure that the retractable lens can be raised and lowered smoothly, there is usually a certain gap around it, which may cause certain problems in waterproofing the phone. However, Huawei Pura 70 Ultra combines a retractable rubber ring with the lens cover. The combination of plates ensures that moisture will not enter the inside of the lens, achieving IP68 waterproof level for the whole machine.
In order to prevent damage caused by accidental drops, Huawei Pura 70 Ultra uses high-precision sensors to accurately sense the stress on the lens. When encountering accidental drops or finger pressure, the lens will quickly and automatically retract, maximizing the Reduce the impact on the lens.
Function-first aesthetic design makes every photo taken more ritualistic
In addition to achieving the perfect integration of a thin and light body with a one-inch outsole through a retractable camera, in order to avoid the ultimate image design squeezing the aesthetic design of the mobile phone, Huawei Pura 70 Ultra prioritizes functions and achieves functions through careful tuning. Perfect unity with aesthetics.
First of all, in terms of appearance, Huawei Pura 70 Ultra has an exclusive red circle designed around the main camera lens, which not only enhances the visual artistry of the product, but also becomes its unique symbol. During the lens retracting process, the original harsh motor sound has been carefully tuned by the R&D team and turned into a rhythmic and textured professional mechanical sound. Not only that, there is also the exclusive XMAGE imaging logo on the camera module, which is like an iconic exclusive accessory in high-end fashion, symbolizing Huawei's unremitting pursuit and firm commitment to image quality.
In addition to leading the development of a new generation of imaging technology, Huawei Pura 70 Ultra is also full of details in enhancing the ritual sense of taking pictures. The mechanical sound when a professional camera is turned on, the feel when rotating the lens, and the “click” when the shutter is pressed, all make every shooting a unique ceremony, allowing people to truly feel that they are recording the beauty of life. moment.
