Samsung is reportedly developing a dual under display camera (UDC) technology to enhance the face unlocking feature, according to a patent. This technique might be used as a tool to scan the subject''s face from multiple angles at once, thus creating a 3D/stereoscopic scan to unlock the phone. The Galaxy Z Fold 4 is located on the folding screen.
Samsung is working on a method, apparatus, and storage medium for authenticating the user as per the patent, which was filed in March 2021 and published this week. The company seems to be developing dual UDCs that will scan the user''s face from different angles to unlock the phone.
According to various embodiments, the electronic device is the memory, display, and multiple cameras arranged in the lower part of the display, and at least one processor operatively connected to the memory, according to the Samsung patent. The apparatus also receives multiple images about the user that can then be set up in order to verify the user''s identity based on the final image.
Multiple scans from different cameras might give a more precise picture, according to Galaxy Club. Since cameras are scanning the face from different angles, the face of the user might be enhanced with more depth, which in theory would be less likely to fool as compared to a larger 2D image. Both of these could combine and enhance facial recognition.
The Samsung Galaxy Z Fold 4 is compatible with a UDC camera. In our analysis, we considered the 4-megapixel camera not that high quality and it should not be a choice for clicking selfies. Apple has already pioneered the FaceID technology and relies on face unlock as the only biometric option to unlock the phone or tablet.
