Yes, it is also a patent rendering of LetsGoDigital, a Dutch rendering maniac. After exposing Xiaomi's patent for periscope rotary camera last week, LetsGoDigital released a similar patent for periscope bidirectional camera on February 2, but this patent is from OPPO.

This OPPO patent was submitted to WIPO (World Intellectual Property Office) in March 2020 and passed in October 2020. It can be understood as an improved version of Find X in early 2018. In the middle of the upper frame is a periscope that can be raised. The two triangular prisms face forward and backward respectively. At the bottom are CMOS placed side by side.

This scheme can also ensure that the front and back glass of the original Find X is not perforated (when the whole "forehead" was raised, a seam was opened on the back). The entire patent mentioned that the prism can be rotated to change the viewing direction, and the two cameras can also work at the same time, which can take 360 degree panoramic photos like panoramic cameras, or record videos together like some mobile phones.

The advantage of the new scheme is that the structure is simpler and more reliable, and the industrial difficulty is much simpler than the original Find X. The disadvantage is the same as all periscope cameras: it limits the size of the camera sensor. Most of the large number of patents registered by domestic manufacturers will not become reality. But this is a world where even Samsung Galaxy A80 (2019) mobile phones with retractable back cover and flip camera can be mass produced. It is really hard to predict what kind of mobile phones will appear.
