Samsung applies for patent for dual-screen camera to support face recognition

CTOnews.com, September 25 (Xinhua) Samsung may be developing an off-screen face recognition system that includes two off-screen cameras.

Samsung filed a patent application with KIPRIS (South Korean intellectual property Information Service) as early as March 2021, which was released last week and was included in a Dutch publication.

According to the patent, the method takes multiple images of the user from two angles to better construct a 3D model of the face and use it for authentication. However, Samsung specifically mentioned the use of off-screen cameras.

CTOnews.com learned that so far, Samsung has only experimented with off-screen cameras on its Galaxy Z Fold product line, without a wider range of devices.

From a patent point of view, it may be necessary to place a camera near the bottom of the phone, close to the location of the fingerprint under the screen, or even combine the two into an optical module.

In addition, the patent mentions measuring pupil size, which varies according to lighting conditions and is expected to be used as an additional security measure to prevent the use of things such as photos or masks to deceive face recognition.
