Samsung is developing a face recognition camera system; More information can be found here

Two under-display cameras are used in one. Samsung mentioned

Samsung may be developing facial recognition technology that’s pretty intriguing. two under-display cameras are used in one. Samsung mentioned it in a patent application filed with KIPRIS (Korea Intellectual Property Rights Information Service) in March 2021. The material in question was made available last week and published in a Dutch magazine.

The basic concept is simple: take many pictures of the person from different angles so that a 3D model of their face can be created that can be used for authentication. However, Samsung makes a point of mentioning the use of under-display cameras, which is intriguing in and of itself. The Korean juggernaut has largely tested the technology in its Galaxy Fold series without wider adoption so far.

So, one theory is that Samsung is considering this new dual UDC technology for its foldable devices. And although that may very well be the case, we believe that the technology has broader applications and that the requirement for UDC cameras stems from the need to have the two cameras as far apart as possible in order to distinguish the user from two different ones capture perspectives. This might require placing a camera on the bottom of the phone, near the area where the fingerprints are now under the display. Maybe even combine the two optical modules into one.

The patent does not contain many details. A mockup of a typical “slab” phone with two UDC cameras – one on top and one on the bottom – is still shown. The patent also includes a measurement of pupil size. According to the theory, a person’s pupil size should change based on lighting. This can be used as an extra security step to prevent facial authentication from being hacked using tools like photos or masks.
