On July 13, Huawei hosted the 2023 Innovation and intellectual property (IPR) Forum at the flagship store in Zone G of Huawei headquarters in Shenzhen. For this innovation and intellectual property protection forum, Huawei promotes the reasonable protection and sharing of patents and technology with the concept of openness, cooperation and win-win, so as to promote the innovation and development of the industry. At the event, Huawei officially summarized its technological innovation and summarized it into five representatives, namely: 5.5G, audio and video dual Vivid, smart car GOD network, smartphone 10-speed variable aperture & non-Newtonian fluid screen, and operation optimization technology.

Among the top five innovative technology representatives announced by Huawei, "smartphone ten-speed variable aperture" may be one of the most familiar technologies, which has attracted wide attention from image lovers when it first appeared on Huawei's mobile phones. It is reported that the technology is based on Huawei's previously applied patent for "a variable aperture structure, camera module and electronic equipment" and began mass production on the Huawei Mate 50 series in the second half of 2022. This is the first time that the industry has adopted a similar design on mobile phones, and it is also another breakthrough innovation for Huawei in mobile phones.

At present, products with variable aperture technology are already on the market, mainly Huawei's series of flagship models, of which the Huawei P60 series was released in the first half of this year, which is one of the latest achievements of Huawei in the field of mobile imaging.

Ten-step variable aperture: the aperture revolution of mobile phone photography, leading the image beyond imagination

Traditional cameras are equipped with larger lenses, and people can adjust the size of the aperture manually or automatically. if you want to achieve a natural depth of field like a SLR lens, manufacturers need to install a variable aperture on the phone. Although some mobile phone manufacturers have previously launched mobile phone products with a variable aperture, the application of the two-speed variable aperture is very limited. To truly achieve a multi-stop variable aperture comparable to the SLR on the mobile phone, there are many technical difficulties in both hardware and software.

Huawei has been deeply engaged in the image field for many years and has taken the lead in commercial multi-stop variable aperture, which is the most intuitive embodiment of its R & D strength and technology accumulation. Take Huawei's P60 Pro as an example, it supports ten variable apertures, with a maximum aperture of F1.4 and a minimum aperture of F4.0. When taking portrait photos, users can choose to turn on the large aperture of F1.4, which can bring comparable depth of field and natural virtual effect to the phone itself, which in turn can and further create a good photo atmosphere and highlight the main body of the character. What is presented in the end is a picture of a portrait with an excellent look and feel.

When shooting the night scene, the large aperture can bring more light, effectively reduce the noise generated by the mobile phone when taking night scene photos, provide excellent picture purity, while retaining rich dark details. With Huawei's P60 Pro, users can always record the most authentic side of the world.

The F4.0 small aperture is suitable for multi-person shooting in sufficient light, allowing the depth of field to expand again to ensure that the characters are clear before and after. When photographing flowers, you can also better see the background outside the flowers.

Superfocus night vision telephoto: both far and near are clear, mobile telephoto no longer has a restricted area.

Of course, the variable aperture is not the only image innovation of Huawei's P60 Pro. The technology is based on the main shot of the Huawei P60 Pro, while the Huawei P60 Pro also has a superfocused night vision telephoto camera. This lens has achieved a revolutionary breakthrough in long-focus dark light photography, regardless of distance, regardless of exposure time, this lens can achieve a fairly clear imaging effect. As far as the bright moon on the horizon, close to cute, clear, sharp and unique are the effects that this lens can show.

In the following picture, for example, if users want to get "super moonlight", they can clearly present the night beauty and moonlight at the same time by focusing on the composition and pressing the shutter. The distant moon and the nearby beauty set off each other to form a picture full of atmosphere. It also shows the photographer's more artistic expression.

However, the "ten-stop variable aperture" technology, which has brought great progress to Huawei's imaging ability, is actually only the tip of the iceberg among Huawei's many innovations. after all, it is only one of the five major innovations in this forum. From a long time ago, adhere to scientific and technological innovation, adhere to R & D investment, is Huawei has always adhered to the creed.

Decades of investment, such as a day, has made Huawei accumulate soil into a mountain, water into an abyss. It is reported that Huawei ranks first in the number of patents granted by the State intellectual property Office of China and the European Patent Office in 202112022, and it is also the company with the largest number of PCT international patent applications in the world in 2022. This dazzling achievement is closely related to Huawei's huge R & D investment, which exceeded 160 billion in 2022 and more than 970 billion in the past decade. Within ten years, nearly trillion yuan of R & D investment can be called "high intensity", and this investment has also brought rich returns.

Focus on the products. in recent years, new technologies have been launched for commercial use on Huawei mobile phones, including Kunlun Glass and Beidou Satellite News in addition to the above-mentioned variable aperture technology. While effectively improving the user experience, patents related to these technologies have also become Huawei's intellectual property rights, thus forming a positive cycle of "investment-return-re-investment" innovation.

At present, Huawei has achieved this goal, other companies have acquired advanced technology, Huawei has also reaped the rewards it deserves, and the industry has made progress in this kind of communication. Patent fees are the result rather than the purpose of Huawei's innovation, and reasonable fees are also conducive to innovation, which is conducive to promoting the wide application of technology in the industry. These achievements, like the previously mentioned "variable aperture", are bound to become the cornerstone of Huawei's mobile phone into the future. In the journey of technological research and development and industrial cooperation, Huawei will also adhere to the concept of openness, cooperation and win-win, constantly break through the bottleneck of mobile phone technology innovation and drive industrial upgrading.
