Samsung explores the mobile camera module: dynamically adjust the aperture and focus to bring better shooting results.

At present, most mobile phones are equipped with three or more cameras. In addition to the main camera, they also provide camera lens combinations such as ultra-wide angle and telephoto. In a technology patent recently approved by Samsung, it seems that Samsung is exploring a mobile camera system to obtain more photography options and better image quality.

This practical patent named "Camera Module and Portable Electronic Equipment Including the Module" was submitted in June 2020, and published on August 5, 20021.It was subsequently incorporated into the database of the World Intellectual Property Organization (WIPO) to protect the patented technology on a global scale.

This document mentions a Samsung Galaxy camera with a movable structure. It involves installing three cameras on the back of the device-using wide-angle, ultra-wide-angle and telephoto lenses. In addition, you can add additional cameras.

The main wide-angle camera is located in the center, and the ultra-wide-angle and telephoto lenses are placed on the left and right sides of the main camera respectively. Each lens has a different field of view (FoV). By default, three cameras are placed side by side. Depending on the shooting scene, the user can move the center lens down (through the touch screen), while the other two cameras will move to both sides-forming a T-shape.

As the positions of the three cameras change, the aperture will also change. In a T-shaped setting, the camera has the smallest aperture or small opening-including a high aperture number (f/). For portrait photography, a large aperture (decimal) is usually used to create a blurred background. For city photography or landscape photography, you want the whole image to be clear, so you need a small aperture.

So it is a movable camera with variable aperture and variable FoV. Thanks to this system, the depth of field can be set very accurately. In addition, you can also take qualitative zoom photos.

Anyone who has ever used a system camera to shoot and used an interchangeable lens can undoubtedly imagine the advantages of this system. For example, if you choose a flat lens, your focal length is always fixed-comparable to the current mobile phone. However, with the new development of Samsung, users can choose to zoom in like a real zoom lens.
