On May 21, 2020, vivo held an online communication meeting on the X50 series with the theme of “Weiyuntai·Big Image”, aiming to interpret the flagship image mobile phone to be officially released on June 1 in more detail. The imaging expertise of the X50 series. This communication will focus on the micro-cloud platform of the vivo X50 series, and will give an in-depth explanation on the birth ideas, technical difficulties, and anti-shake effects.
Since the birth of imaging technology, anti-shake and safety shutter have been topics that practitioners in the imaging industry have been discussing. However, due to the size and manufacturing process of mobile phones, anti-shake has never achieved a change in thinking. Faced with the rapid transformation of mobile phones from “photographic equipment” to “photographic equipment”, the industry urgently needs a new anti-shake technology to break through barriers.
Micro cloud platform jumps out of traditional thinking and opens a new era of mobile phone anti-shake
This communication meeting is the second time that the micro-cloud platform anti-shake technology has been unveiled. Following the announcement of the APEX2020 concept machine at the beginning of the year, vivo will use it for the mass-produced X50 series in less than three months. After the investment of hundreds of R&D teams and more than 100 days of overtime, vivo finally brought more details of this technology.
Making big stories on the limited space of mobile phones is what the vivo technical team is best at; under-screen fingerprint recognition, elevating cameras, etc. are the results of vivo’s extreme exploration of the body space in the past few years, and once led the industry direction. In addition to gaining industry reputation, it also accumulated more experience.
The birth of this micro-cloud platform technology is a new challenge for the space layout of the vivo imaging team based on previous experience. With the landing of micro-cloud platform technology, it will also open the exploration of a new era of mobile phone anti-shake.
A number of black technologies support the micro-cloud platform with outstanding anti-shake effect
The internal structure of the micro-head is complex and precise. It consists of a limit mechanism, a double ball suspension, a lens, a voice coil motor, a double S-type FPC cable, a T-FPC, a magnetic power frame and a protective cover; the overall area is about ordinary The average area of the main camera is 5 times that of the periscope camera and 3.2 times that of the periscope camera. After continuous attempts, vivo finally solved this problem by using the special-shaped structure magnetic frame stacking method.
In order to meet the new structure, the processing difficulty of the micro-gimbal head and the material tolerance control have all been pushed up to new standards, which is another impact of the vivo technical team on the technology. In the magnetic frame alone, the material tolerance is nearly doubled compared to the industry’s common ±0.05mm; and the multi-angle three-dimensional design of the shrapnel also increases the manufacturing process difficulty and processing accuracy. At the same time, because of this, the anti-shake angle of the micro gimbal has reached more than plus or minus 3°, which is 300% of the traditional OIS optical anti-shake.
The innate advantage of micro cloud platform is non-destructive and anti-shake
Compared with traditional optical anti-shake technology, the micro gimbal has an inherent structural advantage – non-destructive anti-shake effect.
At the technical level, thanks to the overall movement of the lens and sensor, there is no relative displacement inside the module during the anti-shake movement of the micro-gimbal, which truly achieves 100% overall anti-shake of the module, ignoring the problem of image quality loss at the edge. .
Secondly, with the support of the micro-gimbal anti-shake, the main lens has a larger rotation angle, and the area of the anti-shake range has reached 3.2 times that of the OIS optical anti-shake mobile phone, providing better anti-shake stability.
Based on the advantages of micro-PTZ anti-shake, vivo has optimized the combination of soft and hard for sports scenes. On the basis of the “X-axis rotation + Y-axis rotation” micro-gimbal anti-shake, combined with the “X-axis translation + Y-axis translation + Z-axis rotation” Electronic image stabilization, the combination of the two finally achieves “X/Y/YAW” /PITCH/ROLL “5-axis video anti-shake” effect. Supplemented with intelligent motion tracking function, users can easily obtain a more stable, clear and smooth shooting experience in sports scenes.
Ultra-sensitive micro-gimbal vivoX50Pro captures more light
Based on the characteristics of the micro gimbal, the overall photosensitive ability of the X50Pro has also been improved accordingly. Under the basic conditions, the main camera of the X50Pro has better photosensitive performance, which is 39% higher than that of the X30Pro; the photosensitive performance of some handheld scenes is up to 220% higher than that of the X30Pro, and the details of the dark parts of the picture are richer.
In terms of data, according to the data provided by vivo laboratory, when OIS is turned off, the dark light forming ability of photos with 1/50 second shutter is close to the dark light forming ability of photos with OIS open 1/8 second shutter, so OIS optical protection The ability to form a dark light film with shaking is 6.25 times that of a dark light film with anti-shake off;
On the other hand, the anti-shake of the micro gimbal can achieve the same film formation as the ordinary OIS optical image stabilization under the condition of 1/4 second shutter time. Twice the ability to shake the dark light into a film.
It is reported that the vivo X50 series will officially meet with you on June 1, when more black technologies about the X50 series will be officially exposed. Focusing on photosensitive night photography, let us wait and see how we can “catch more light” to capture the beauty of the night.
