Shulou(Shulou.com)06/03 Report--

Kurt Lewin, a German psychologist, initiated the academic context of topological psychology. This school believes that one of the most important general attributes of psychological life space is that this space has structural attributes. Our love and hate, joys and sorrows, emotions or dislikes are all based on a physical model that can be quantified.

This theory can explain many things, for example, why do we like the so-called ingenuity? It is because craftsmen put a lot of effort into polishing the details when making this item, which makes it different from simple production or modular reproduction products. Although we can not immediately and accurately understand the differences in the details, the subconscious memory vector can still make us instantly like the work that put more painstaking efforts into it. Then we will return to the rational world to find the logic behind the heartbeat.

Recently, readers have often told us that when using the Huawei P40 series, they have the feeling that they are often surprised by a detail, but it is difficult to describe the reasons behind this strong differentiation. Recently, we have an opportunity to go back to the rational world and help you understand the secrets and stories contained in the details of the P40 series.

Bruce Lee, president of Huawei's first mobile phone product line, is an online celebrity in the eyes of "pollen" and technology enthusiasts. After Huawei's flagship plane is released every year, students who want to know more about the technology and the research and development story behind it will be waiting for Bruce Lee's "exclusive practical information".

Bruce Lee shared the "never told" R & D story behind the P40 series at a Huawei school celebrity sharing event at the Huawei Intelligent Life Pavilion (Shanghai Aegean Sea) on June 14. It has developed more than 50 courses, has more than 20,000 certified lecturers, and conducted more than 2 million Huawei schools. to some extent, it has become a window for users and Pollen to understand Huawei offline and understand Huawei's story and way of thinking. it is also a channel to meet more like-minded "pollen". Bruce Lee's sharing has become a highly anticipated "annual retention program" for Huawei schools.

When Huawei P40 Pro+ is fully launched, we take this opportunity to explore what thinking and polishing the R & D team has experienced behind the P40 series, and finally hide the surprise in the details.

How do you bend a piece of paper on all sides?

Up to now, it has become common sense to look at the curvature and Radian of the mobile phone screen first. And how to make a more aesthetic and innovative curved screen has also become the primary test of mobile phone design.

In Huawei's P40 Pro and P40 Pro+, the industry debuted a 6.58inch Quiqu overflowing screen. By allowing the upper and lower screens to be bent, the Huawei P40 Pro makes the entire screen look like a glass of overflowing water, protruding slightly above the mouth of the cup, showing dynamic tension.

Free and easy very four songs overflowing behind the screen, but it is not so easy story. Bruce Lee shared such a problem in the mobile phone screen industry chain. Bending the mobile phone screen is not complicated in the process, but the screen stretching is still very difficult. Because at present, thin film semiconductor technology is widely used in mobile phone screen. In this process, metal wiring is arranged under the screen to achieve the display effect, and the metal line can not be pulled, otherwise it is easy to appear bad points.

This truth is like a piece of paper, which can be bent up and down, or left and right, but if it is bent in four directions at the same time, the paper is bound to be damaged. In order to achieve the overflowing effect that finally appeared in the P40 series, the R & D team has been thinking and exploring for many years before finally handing over the answer paper this time. Because the failure rate of the bending angle is too high, the R & D team experimented repeatedly for countless times, and finally achieved the beauty of the curved surface from delicacy to millimeter by controlling the precision and curvature.

Extreme design has always been an indomitable art.

Two pieces of ceramics to achieve flawless consistency

When it comes to design, a very unique feature of Huawei P40 Pro+, which has just been put on the market, is that it is equipped with a new nanocrystalline ceramic process in its design. The fuselage uses a ceramic texture of white if fat and black as ink jade.

Some friends may have some doubts when it comes to ceramics. Why did the Huawei R & D team launch the ceramic fuselage in the top P40 Pro+?

The reason behind this is that ceramic is a kind of artificial material with strong plasticity and great differentiation. This can be seen from the difference in the price of rice bowls at home with those of Yuan Qinghua and Chenghua. The ceramic material that appears on the Huawei P40 Pro+ body is made of microcrystalline zirconium and special materials. The firing process takes five days and five nights to achieve the final delicate feel. And this kind of material is extremely hard, the hardness is close to the sapphire, and can make the whole extremely thin.

At the same time, Bruce Lee also shared a more "difficult" detail story behind the ceramic fuselage. We know that no two bowls in the same series can reach a perfect agreement, just as no bowl can achieve a perfect circle. This is because the moisture of the ceramics is dried during the firing process, resulting in an unpredictable shrinkage. But the phone body obviously cannot tolerate differences in body size, especially the P40 Pro+ is a highly waterproof phone whose tightness requires that the body cannot be deformed at all.

In order to solve this problem, the R & D team finally chose to enlarge the fuselage first. Then a high-precision CNC CNC machine tool and a diamond custom bit are used to mill the phone body to the final size needed. The fuselage of a mobile phone needs to be milled with high precision for half an hour on the machine tool in order to reach a flawless agreement.

This regardless of the cost of carving, the final P40 Pro+ than glass more wear-resistant, fall-resistant, but as warm as jade ceramic fuselage. It also makes the overall fuselage lighter and thinner, with an average ceramic back cover of only 0.4mm, which allows the product to place a powerful ultra-perceptual Leica five module with the same thickness as the P40 Pro.

In four moments, I will be attracted to the light and shadow.

When it comes to Huawei's P series, photography is a motif that can never be avoided. We know the photography ability of Huawei P40 series, and there is no doubt that it won the first place in the industry. But from Bruce Lee's sharing, we can understand the thinking and story behind "first".

The P40 series, which focuses on the concept of super-perceptual photography, wants to achieve three transcendences in the hope of the R & D team: beyond time, beyond space, and beyond form. These three transcendences are gradually anchored to a series of details of the P40 series, from sensors and camera modules to image computing engines and auxiliary photography functions. If you find it difficult to remember with too much technology, we might as well tell a few stories that can happen in an instant.

In fact, behind the P40 series, all the efforts made by the R & D staff is to make you discover this moment faster-the moment when you will be attracted to the recording image and the P40 series products.

Encounter Meow by chance

Photographing cats is a very strange but nostalgic hobby in city life. Whether it is the secret love shoot of the master cat by the shovel shit official, or the encounter of a cute creature full of vitality on the way to and from work, it is one of the great joys of mobile photography.

But another characteristic of a cat is that it comes and goes without a trace, and the best form is often only for a moment, and often it drifts away before you can focus.

In order to solve this problem perfectly, Huawei P40 Pro+ has created the full-pixel eight-core focusing capability in the industry. Based on Huawei's largest 1.28in super-sensing sensor to date, the original RYYB array function and Huawei's self-developed photosensitive algorithm, the P40 Pro+ can shoot high-definition images anytime, anywhere. Especially in the focusing ability, through four-in-one pixel focusing, the 50 million pixels of the main camera have the ability to focus, all can detect depth of field, and any position of the frame can return the focus result.

This allows the P40 Pro+ to focus so quickly in the Anguang situation that cats have no chance to escape.

In front of the Imperial Palace

Tell me another moment that is actually quite common, but you may not have noticed. Taking a literary photo in front of the red wall of the Imperial Palace is a compulsory course for almost all girls and a small number of boys who come to Beijing today. But in this red background, the photography system is actually very difficult to capture the white balance. This makes it possible for mobile phone photography to be unable to distinguish between portraits and faces, and the final debugged colors are more or less strange.

In order for us to take a good picture against a dark background and lack of white spots, the P40 series is equipped with an 8-channel multispectral color temperature sensor. With the AI AWB algorithm, the color accuracy is improved by 45% compared with the 3-channel color temperature sensor commonly used in the industry.

This sensor, hidden next to the flash, allows the AI system to capture the color balance most accurately, thus realizing the high-level image capture of people with bright backgrounds.

Third, under the snow

The shooting of portraits in the snow is a big problem when we travel in winter. Often shot in the snow, the portrait is either too exposed or too dark, daily failure, but also have to choose between good-looking snow and good-looking people, it is a great pity. In order to solve this problem, the daily operation of DSLR photographers is to put on ultra-multiple filters and try how to shoot under different light sources and shadows one by one. Often the filter is not found properly, and the light source has changed.

To solve this problem of light and shadow, the best way is to let the lens recognize which is snow, which is man, and which is shadow. This requires the photography system to have strong identification and computing ability. In the P40 series, it is equipped with a powerful computational photography system XD fusion image engine.

With the help of it, multiple cameras can carry out complex recognition calculation, image semantic segmentation and task assignment during collaborative shooting, such as collaborative zoom in different scenes. Taking pictures under the snow, XD fusion's ability contribution is also very outstanding. Through AI image segmentation, it can understand the position relationship of snow, shadow and people on the image, give different light compensation and algorithm optimization, and finally use AI to help each image get its place and present the best winter moment.

IV. In the mountains

In addition to losing weight, another pleasure of traveling across mountains and rivers is taking pictures. But there is a huge problem with taking pictures between the mountains, that is, the good scenery in the distance is so hazy that it is difficult to capture clearly. On the other hand, carrying a telephoto camera and a SLR camera really puts a heavy burden on mountain climbing, and the common sense of "zooming by walking" is difficult to match the miraculous craftsmanship of nature.

When Huawei P40 Pro+ brings 100x binocular zoom ability for the first time in the industry through its original multi-reflection periscope telephoto lens, it is believed that the vast majority of fans looking far away will no longer favor telephoto + SLR.

Under the premise of light and thin body, the P40 Pro+ supports 3x medium and long distance optical zoom, 10x ultra long distance optical zoom, 20x hybrid zoom and 100x digital zoom. The ability of long focus far exceeds that of the human eye, and truly transcends space photography.

Behind this, it is the R & D team that has tried every means to achieve 10x optical zoom in limited space. The periscope camera already presented in the P30 series has been transformed into a multi-reflection periscope telephoto lens after five times of light reflection in the P40 Pro+. There are a lot of difficulties behind this lens, such as each light reflection will cause light loss, if the mirror is not smooth, there will be optical interference and so on. To this end, the R & D team used a special nano-level high-precision reflector and added glass lenses to improve the stability and light transmittance. And multi-shot periscope telephoto also needs to be equipped with a strong enough chute AF focusing motor, coupled with two-axis rotation anti-shaking, to finally achieve the king-level telephoto shooting ability, so that every plant and tree on the opposite mountain, a bird and an animal can be seen.

In addition, the P40 series also brings the dim light ability beyond the human eye in the imaging system; a series of magical functions such as expression capture, motion posture capture, passerby removal, reflection removal, etc. realized by the powerful end-to-side AI computing power; in video shooting, there is 16-in-1 pixel fusion technology, original audio zoom function, and so on.

Countless details are contained in it, just to wait for your heart in that moment after a certain photography.

The heart is happy in a microsecond.

Many people say that today's mobile phone products have entered a strong homogenization stage, with a high degree of duplication of capabilities and features between products. This view, I think the R & D team behind the P40 is difficult to accept. Because we can see that they make a difference to too many details, from an on-screen point of view to a polishing on the fuselage. From taking photos anytime and anywhere, to the powerful dual-card, dual-standby, 5G performance, and the distributed office and life experience brought about by EMUI10.1-from hardware to software, from photography to office, every detail is pregnant with thinking and judgment in research and development, showing such a distinctive difference.

If you don't have any knowledge of mobile digital, nor do you study and evaluate the patience of the product in detail, then maybe something better will happen after you get the P40 series. Because falling in love with a moment of experience, a design detail, a capture of light and shadow surprise, is so accidental and inevitable.

The P40 series will continue to surprise you in details. Behind the R & D team thousands of times to think, temper and carve, is to concoct that one to make your heart happy moment.
