First of all, let's find out why mobile phones need multiple cameras. As far as today's mobile imaging system is concerned, the most important and core thing is to complete the focal length of the camera. At present, most mainstream lenses are actually ultra-wide-angle, wide-angle and telephoto. As for other blur lenses, macro lenses, etc. They can be integrated with other lens functions or simply included in a three-camera system.

There is one exception, however, similar to the ToF footage carried by Huawei and Samsung. The help of this lens to imaging is mainly reflected in improving the focusing performance of the imaging system. But ToF also has its own limitations, that is, the distance between the main body and the phone can not be too far, otherwise the ToF lens is also a ldquo setting rdquo.

So is there any technology that can improve the focusing performance of the whole scene? The full-pixel dual-core focusing technology we heard earlier was developed for this purpose. For example, the OPPO R9s is the first mobile phone in China that uses full-pixel dual-core focusing technology. Only later, the number of sensors using quadBayer arrays, such as IMX586, increased, and the technology remained on Sony and Samsung's flagship phones.

However, the emergence of the OPPO Find X2 Pro solves this problem; its customized large-size IMX689 brings us something completely different. 1Mather 1.43 large size and 2.24 degrees; single pixel size (four pixels merged) further refreshes the records of the previous generation of sensors. According to the official data of OPPO, the photosensitive area of IMX689 has increased by 96% compared with the previous generation, and the photosensitive sensitivity has increased by 130%.

In addition, the most important thing is the all-pixel omni-focusing technology pioneered by IMX689, which uses the four-pixel arrangement of quadBayer to greatly improve the success rate of focusing in a dark light environment. According to the data provided by OPPO, even in the extremely dark environment of 1.25lux, the success rate of focusing is still 97%, giving users a higher shooting rate and a greater possibility to capture wonderful moments in life.

In addition to the main camera, the OPPO Find X2 Pro uses an IMX586 as the phone's ultra-wide-angle camera, which matches the periscope camera closer to Reno's 10x zoom version, completely covering the focal length. In addition, the ultra-wide-angle camera also supports 3 cm macro photography, and the independent color temperature sensor above the main camera can assist photography to make the color of the photo more accurate. Together, the OPPO Find X2 Pro can save fuselage space as much as possible, while having the top influence.

Also, remember the 10-digit color depth we mentioned on the screen? The OPPO Find X2 Pro provides you with a full range of 10 billion colors: in addition to the on-screen display, the OPPO Find X2 Pro is also the industry's first phone to support 12-bit raw data images. As a professional user, it can provide more and more space for later image processing. Let you see richer colors when shooting and fully experience the 1 billion color space provided by OPPO.

OIS Optical Image Stabilization works with gyroscopes by adding a maglev lens to the lens group. When the fuselage vibrates, as long as the camera system detects a slight jitter, it will immediately control the lens float to compensate for the jitter and avoid the light path jitter.

EIS electronic image stabilization is a software compensation algorithm. It reduces the blurred image by clipping and compensating the image, and its principle is more like the ldquo of photos. The post-processing realizes the stability of the video image by analyzing and collecting the image on the sensor by software.

As early as on OPPO Reno2, HIS hybrid anti-shake technology is used, which combines OIS optical anti-shake and EIS electronic anti-shake. The addition of double anti-shake technology makes the video picture more stable. It is worth mentioning that OPPO Reno2 also greatly enhances the sensitivity of the gyroscope, because the gyroscope can provide equipment jitter feedback data for the anti-shake system, improve sensitivity and enhance the efficiency of video anti-shake.

Later, video anti-shake function evolved on Reno3, adding super anti-shake Pro mode. Because EIS electronic image stabilization requires cutting and keeping the picture stable, the video shot is smaller than the shot. Super anti-shake Pro mode cuts and stabilizes the ultra-wide-angle lens, thus increasing the viewing area by 87%.

With the replacement of the OPPO Find X2 Pro, the camera's video anti-shake effect has been comparable to that of a professional sports camera, even supporting 1 billion-color Live HDR video recording. The video is not only more colorful and vivid, but also the HDR shooting algorithm independently developed by OPPO can ensure the accurate restoration and recording of the subject and background in the backlight scene.

After learning how OPPO can improve video shooting, I believe many friends are also interested in another advanced question: why does OPPO put so much effort into video shooting?

Judging from the current situation, video shooting and production seems to be far away from the lives of ordinary people, and the threshold of technology and equipment needed to shoot a good video is still too high. It takes time, effort and money, which makes many rookie friends who are interested in making videos stay away.

However, this is an era in which technology and requirements complement each other. With the development of mobile communication technology, video has become one of the important social ways. The arrival of 5G era has further accelerated the spread and popularization of high-quality video. At this time, ordinary people can also make good videos, which has obviously become the next challenge for the development of smartphones.

In fact, OPPO brings not only the reduction of the threshold for video shooting, but also a complete set of solutions from shooting to post-production: video auxiliary equipment is replaced by the blessing of video super anti-shake function; through continuous upgrading of hardware and in-depth adjustment of image quality, professional video recording equipment has been replaced; through Solop real-time recording APP, you can achieve very low threshold video post-production.
