On July 8, it was reported that with the release of Huawei P30 Pro and OPPO Reno's tenfold zoom version, mobile phones equipped with periscope cameras finally appeared in 2019. It seems that Xiaomi also wants to join this trend. On July 2, the State Intellectual Property Office approved a patent application, which disclosed the details of the camera technology Xiaomi might use.

The name of the patent is "camera assembly and electronic equipment". The patent shows the combination of a main camera and at least one periscope. The periscope will be perpendicular to the main camera. Because light will be refracted in the periscope, the periscope module can realize different times of optical zoom without increasing the size of the equipment.

It is reported that the focal length of Huawei and OPPO cameras can reach 125mm and 135mm. If Xiaomi applies this technology to mobile phones, its focal length should also be within the same range.

It is reported that the Xiaomi MIX 4 may be the first Xiaomi mobile phone equipped with a periscope group. Previously, Wang Teng, the product director of Xiaomi, said that the Xiaomi MIX 4 will use better light sensitive components than Samsung GW1 (64 million pixels).
