How is a “star” made? Micron-level precision Huawei reveals the process of the creation of telescopic lenses

Mobile imaging has made great strides in recent years, but it has come at a heavy cost.

We can clearly see that the sensors of today's flagship mobile phone cameras are getting bigger and bigger, and the TTL (total lens length) is gradually lengthening, causing the lens module to become thicker and thicker. The rules of body aesthetic design are broken, and a large number of products with “Oreo” on their backs are concentratedly appearing, making it difficult for the thin body of the mobile phone and the top imaging to coexist, seriously affecting the user experience.

Do we have to put up with heavy lens modules and lose touch with the aesthetics and sense of ritual of mobile phones if we want good imaging phones? Of course not.

As we all know, since its launch in 2012, the Huawei P series has always been a promoter of innovation and progress in mobile imaging technology, leading the development direction of generations of mobile phone imaging technology.

To address the above pain points, Huawei P series has fully upgraded and renewed its Huawei Pura series. The first model launched by Huawei Pura 70 series is the first in the industry to use a super-focusing telescopic camera. Through the unique rotating telescopic lens structure, it perfectly combines first-class images with the thin and light aesthetics and sense of ritual of the mobile phone. Within Huawei, they use the code name “Star” to refer to the super-focusing telescopic camera, which not only reflects the technological romance developed by Huawei, but also shows the unique technological aesthetics of Huawei Pura series.

For quite a long time, some manufacturers have tried the telescopic lens solution, but they either only existed in the concept stage and never went into mass production, or failed to break through the technical bottleneck. How did Huawei break through? Since the launch of the Pura 70 series, the discussion around telescopic cameras has always been a hot topic in the technology and digital circles.

Recently, in the video “The Birth of a Star – Unveiling the Story Behind the Super Focusing Telescopic Camera”, Huawei revealed for the first time the ultra-precise and ultra-reliable birth process of the super focusing telescopic lens. Through micron-level precision and hundreds of thousands of tests, every image creation by the user is like a “star” rising, full of a sense of ritual.

First of all, the assembly of the stellar camera is an ultra-precise process, which includes the assembly of the rotating telescopic structure and the assembly of the variable aperture to the lens. All of these need to be carried out in a strict dust-free environment and meet the 100-level dustproof requirements and spacecraft manufacturing-level cleanliness.

In addition, the parts and assembly processes are precise to the millimeter, so that each part can achieve micron-level manufacturing accuracy.

For example, the rotating telescopic lens structure undergoes 255 consecutive manufacturing processes, and the minimum tolerance of springs and other parts needs to be controlled at 0.01mm when assembling. Even the key precision gear parts need to be manually installed by professional craftsmen to achieve 0.005mm high-precision alignment, as precise as the installation of Swiss watches.

When the variable aperture is assembled on the telescopic lens, the assembly accuracy can reach 0.015mm, which is smaller than the diameter of silk. The whole process is strictly laser calibrated to ensure that it is accurate to the last detail.

Secondly, the testing of the Stellar lens module and the whole machine is also a super reliable process. The Stellar module test needs to pass 20,000 buffer tests and 30,000 load lifting tests, and finally achieve fearlessness of pressing, bumping, and falling. The whole machine has passed the 2-meter deep diving test and achieved 2-meter IP68 dust and water resistance, which can provide continuous and comprehensive protection for the rotating telescopic lens.

From the working principle, Huawei Pura 70 Ultra super focusing telescopic camera adopts a rotating guide transmission system to create a larger working space for the lens in a narrow body. When the camera is working, the lens automatically extends, and the increased thickness space is used for the focusing movement of the camera lens; when it is not working, the lens automatically retracts, and the storage space does not increase the thickness of the whole machine, making the thickness of the phone significantly thinner. In this way, a 1-inch large-bottom sensor can be accommodated in an 8.4mm body, and a maximum aperture of F1.6 can be achieved.

This innovative design perfectly combines the advantages of a large sensor and a large aperture. It can not only capture more details and make photos clearer and more delicate, but also provide more light in low-light environments to ensure the brightness and layering of photos.

With the dual advantages of a large bottom and a large aperture, the Huawei Pura 70 Ultra brings the industry's largest amount of light to the main camera. Coupled with the assistance of the XD Motion motion engine, it can even freeze the 300km/h fast moment and record the moment of lightning speed, becoming the real king of capture speed. In daily shooting, whether it is a speeding car or a high-speed maglev train, it can be easily captured.

At the same time, the 1-inch large-bottom sensor can also capture more details and color levels. Whether it is a landscape outdoors or a busy city, the photos can record more delicate and rich colors. When shooting portraits, the large aperture of F1.6 can achieve a depth of field blur effect comparable to that of a SLR, making the subject more three-dimensional and prominent, bringing a more realistic portrait effect. In the evening, at night, indoors and other low-light environments, the large aperture can bring in more light and reduce noise and blur.

It is worth mentioning that Huawei Pura 70 Ultra also provides safety protection for every user's creation through its ultra-reliable lens structure. The machine has designed a sophisticated buffer structure inside the rotating and telescopic lens structure. This structure consists of 12 guide pillars and 8 springs, and high-strength and high-toughness piano steel is used as the spring material to ensure the stability and durability of the lens. For example, when the user accidentally presses, knocks or collides with the main camera, its built-in position detection system and intelligent control system can quickly identify the abnormal situation and drive the motor to quickly retract the module, realizing a stable and smooth buffering function.

For scenarios such as the phone falling, this system can also actively obtain the acceleration and gravity sensor data of the entire device, determine its weightlessness and falling state in real time through algorithms, and retract the main camera lens module before the phone falls to the ground, thereby achieving high reliability of the entire device.

In addition, the Huawei Pura 70 Ultra rotating telescopic lens also has a polymer liquid silicone protective layer, which has excellent tear resistance, heat resistance, aging resistance, corrosion resistance, etc. Even if the user accidentally lets cola, sugar water, cosmetics and other foreign objects penetrate into the gap, the phone can be soaked in clean water and cleaned with a dust-free cloth to ensure the clarity and service life of the lens.

The Huawei Pura 70 Ultra's star module also brings innovation to the user's shooting experience, making every photo taken by the user full of ritual. Experts from the Huawei camera team have carefully developed a motor drive algorithm. This algorithm dynamically adjusts the motor drive frequency to tune the sharp sound of the motor when it rotates at high speed into a rhythmic tone, so that the tone rises synchronously with the module.

When users use Huawei Pura 70 Ultra to record their lives, from the XMAGE logo on the imaging module, the exclusive red circle embellishing the lens, to the professional mechanical sound when the lens is extended, every creation is an enjoyment with full emotional value.

How is a

Every time the user starts the camera to shoot, every time the shutter button is pressed, the camera starts, and the lens slowly extends, it is like a star in the universe rising in front of you, illuminating the world in front of you with its unimaginable light, awakening people's pursuit and yearning for the sense of ritual in taking pictures.

From precision parts to rigorous testing, from technological innovation to a unique sense of ritual, the Huawei Pura 70 Ultra has set a new milestone for mobile photography with its revolutionary super-focusing telescopic camera. This innovative design not only brings users an unprecedented imaging experience, but will also promote technological progress and quality improvement in the mobile phone industry.

What’s more worth mentioning is that Huawei’s Pura 70 series appears in the first batch of updated models of pure-blooded Hongmeng. You can buy it now and try out the pure-blooded Hongmeng in August this year and appreciate the unique charm of the new system!

Thanks to its powerful imaging and flagship performance, the Huawei Pura 70 series has been well received since its launch. Public market information shows that the shipment volume of the Huawei Pura 70 series has increased by 125% year-on-year compared to the P60 series. On July 18, Huawei launched a limited-time summer gift promotion with discounts of up to 1,000 yuan. For those who want to experience the Huawei Pura 70 series, this is a good time to buy it.
