South Korean tech giant Samsung is working on a pretty interesting facial recognition system that includes two under-display cameras.
Samsung’s new system was described in a patent application Samsung filed with his KIPRIS (Korea Intellectual Property Rights Information Service) in March 2021.
The document in question was published last week and was picked up by a Dutch publication. The core idea is fairly simple. H. Acquire multiple images of the user from two perspectives to better construct a 3D model of her face and use this for authentication purposes.
However, Samsung specifically mentions the use of an under-display camera, which in itself is interesting. So far, the South Korean giant has more or less experimented with the tech in its Galaxy Fold line without a wider release.
One speculation is that Samsung is considering this new dual UDC technology for foldable devices. That may indeed be the case, but there is a broader sense to this technology, and the desire to use a UDC camera is from the user’s point of view as he moves the two cameras as far apart as possible in order to get two different angled views.
This is due to the necessity. This may require the camera to be placed near the bottom of the phone where the under-display fingerprint scanner is currently located.Combining the two he could also be a single optical module. Another thing mentioned in this patent is pupil size measurement. The idea is that the size of the human pupil should change depending on the lighting conditions.
The concept is certainly interesting, but it should be noted that at this early stage it is just a concept, not a real product or representation of it.
