Huawei is developing a smartphone with an aperture blade camera inside the lens similar to a professional camera

Camera on smartphones, although there have been many upgrades to bring users higher image quality over time, there is still a limitation compared to professional cameras, which is the ability to control aperture. The flexible opening and closing of the aperture will help the photographer adjust the amount of light coming to the sensor, opening up the ability to take photos of exposure, panning, … still done easily. easier on camera.

Samsung used to experiment with adding aperture blades to the camera in 2018 with its Galaxy S9. At that time, the image sensor on smartphones was still quite small, the ability to absorb light was weak, so adding an aperture mechanism brought more disadvantages than advantages. Samsung and others have since abandoned this idea, instead adding different types of cameras to increase the versatility of the camera system.

Recently, Huawei announced that it will test this idea again with a new patent. Huawei’s aperture application will be similar to that of traditional camera lenses, with 6 blades controlled by chokes, magnets or piezoelectric motors, instead of just 2 halves as above. Samsung Galaxy S9. This mechanism can be opened and closed more flexibly, creating different apertures to easily control the amount of light, depth of field of the camera.

This is still a paper patent, so it is unclear when Huawei will put it into practice or what kind of camera it will be applied to. But the company says that this mechanism can be used on all cameras on the same smartphone, allowing users to control the aperture at any focal length.
