Huawei has officially announced a new patent related to variable aperture lenses. Earlier, the company launched the Mate 50 series and P60 series with a 10-stop variable aperture lens , which uses a six-blade opening and closing design.
Translation of the patent description
The patent specification states that in a conventional conventional camera module, the aperture value f-number is fixed and cannot be changed. This is because the size of the camera module increases due to the mechanical devices required to change the f-number. Therefore, a compact mechanical device is required to adjust the f-number, which is intended to be mounted on a miniature camera module. An object of the present invention is to provide a micro-device suitable for a variable aperture of a micro-camera module. Another object of the present invention is to correctly control the size of the aperture by directly detecting the position of the rotor.
