Recently, a Huawei patent titled "Aperture, camera module and electronic equipment" was exposed. It was submitted to the China Patent Office on February 11, 2020, and was officially announced on August 19, 2021. announced. It is understood that the patent mainly describes Huawei's camera equipped with a variable aperture for future mobile phones.
According to the description of the patent document, Huawei hopes to use at least 6 aperture blades to generate a larger aperture through sliding changes, and adjust the amount of light entering the camera by adjusting the aperture blades. The inspiration for the research and development comes from the fact that the aperture in a SLR camera is a structure that can be equipped with a shutter to adjust the amount of light. This patent is mainly used to adjust the amount of light entering the camera module of small electronic devices in conjunction with the shutter.
This method of adjusting aperture on mobile phones has actually been used on Samsung Galaxy S9 a long time ago. The biggest highlight of the phone at that time was its use of f1.5/f2.4 intelligent variable aperture. Aperture: When shooting at night, the large aperture of f1.5 will be automatically used, and when there is sufficient light during the day, the aperture of f2.4 will be used. As for when Huawei will actually implement this technology, it will take some time at present.
