Samsung is working on a dual sub-display camera system that should improve security and facial recognition. This is according to the patent application, which has now been published on the KIPRIS (Korea Intellectual Property Rights Information Service) online service.
Samsung filed this application in March of last year, i.e. before it was introduced to the scene Galaxy From Fold3. It was published yesterday and the website drew attention to it GalaxyClub. The patent describes a dual sub-display camera system designed to improve the recognition of a subject's face from multiple angles at once, which would in a way create a 3D/stereoscopic scan. The document also suggests that this system would be able to measure the user's pupils for better biometric security.

The first smartphone Galaxy, which uses a sub-display camera, is from last year Galaxy From the Fold. It has a 4MPx sensor with a pixel size of 2 microns and a lens aperture of f/1.8. In its successor, the sub-display camera has the same parameters (although it was speculated for a while that its resolution could be four times higher), but Samsung managed to hide it at least better. However, the technology still hasn't reached the point where it's invisible to the naked eye.

We can only speculate at the moment about when the technology described in the patent could see the light of day. In general, patent applications do not guarantee that the product will ever be brought to market. Considering that Samsung has already successfully materialized the patents related to the sub-display camera, we can expect that it will do so in the future with its improved version.

Well, Samsung should do something about it, I do Galaxy Tab S8+ and face recognition works really well. Sometimes it works, sometimes it doesn't, it often works better with less likely angles. Golden FaceId. I prefer to use the fingerprint reader, but in many cases it is simply in the wrong place and it is quite inconvenient to get to it, for example when I am lying on my right stomach on the couch and I have it on the coffee table, I cannot reach the right side of the display with my right hand, I am lying on it and I have to stretch my left a lot, the camera obviously can't handle it...
