How does the mobile phone camera capture the "out of sight" approach?
Close enough to see the structure of the ice crystals and cell slices of the snowflakes.
How does the mobile phone camera capture the "out of reach"?
Hundreds of meters away, flowers and trees are clearly visible.
The liquid camera is the answer given by Xiaomi, a device with macro and telephoto, perfectly presented.
Let's listen to the answer given by the second prize winner of the 2021 Xiaomi Annual Technology Award: Liquid Camera Team.
The application of liquid lenses to mobile phone cameras is another revolutionary breakthrough in the development of mobile phone imaging. In the field of imaging, Xiaomi debuted a liquid camera on the MIX FOLD. Innovative liquid cameras that enable the coexistence of macro and telephoto and achieve the first mass production in the industry.
Users can easily take pictures in different macro and telephoto scenes with a mobile phone, without worrying about switching camera devices and missing stunning and warm moments, and immersively record beautiful moments.
After more than two years, we broke through the limitations of traditional mobile phone telephoto solid-state lenses, modules and motors. Through the liquid camera, not only can the module be made small, but also the magnification and image quality effect can be greatly improved. Under the premise of ensuring high pixels and module size, when achieving the same 3cm macro imaging, the picture quality effect of the central field of view is nearly twice as high, and the MIX FOLD mobile phone screen can present a lossless magnification effect of up to 12.25 times.
Xiaomi liquid camera engineers have innovatively designed the focus scheme and developed the AF algorithm to achieve high-precision focusing in a large object distance range, which solves the problem of poor image quality of conventional mobile phones through picture cropping and amplification.
Liquid camera itself material, structure and drive mode are different from the traditional solid lens camera, liquid lens is like a drop of water into a plastic capsule, in retaining its original shape to achieve precise control, which brings a lot of difficulties to the structure, motor design. Due to the complex assembly connection methods, the high accuracy of the nanometer level and the high sensitivity of the liquid state, the development of liquid cameras is a huge challenge. We spend a lot of time in our R&D process conducting simulations and performance impact assessments to determine the right specifications for components and strike a balance between design performance and mass production.
▍Vice Chairman of the Xiaomi Group Technical Committee Wang Feng commented on them in this way
“
Telephoto can be far away, macro can be macro at close range. With a liquid camera, mix fold's phone footage can render up to 12.25 times lossless magnification. In the field of mobile phone cameras, Xiaomi's engineers have challenged the impossible again and again, and seen the future with innovation!
”
At present, Xiaomi has more than 1,500 imaging engineers and more than 2,000 authorized imaging patents worldwide. On the list of DXO Mark, the world's most authoritative third-party evaluation agency, Xiaomi mobile phones have reached the top 4 times, reflecting the technical strength of Xiaomi imaging.
In the face of the new liquid module devices, our engineers have explored little by little from scratch and established their own design specifications, test methods and acceptance standards. In the future, they will continue to define the future development trend of cameras with innovation and explore more camera black technology.
