The Tensor G6’s picture sign processor (ISP) is rumored to help an under-display IR digital camera system. This method is claimed to be specifically designed to be power-efficient. Whereas there’s nothing definitive right now saying that this will probably be used for face unlock, it is the obvious use case.
The Pixel 4 had an analogous system that used a dot projector, flood illuminator, and two IR cameras. This allowed it to acknowledge customers in all lighting circumstances. The know-how was thought of cutting-edge on the time and was even used for safe funds and app authentication. Nevertheless, the know-how was discontinued in later Pixel fashions, probably as a consequence of price or design issues.

Subsequently, the Pixel 7 switched this to a purely camera-based method, then the Pixel 8+ upgraded this technique to Class 3. This swap by the Pixel 8 successfully allowed face unlock for use for Google Pockets/Pay transactions, banking, and different app sign-ins.
Regardless of the implementation would possibly appear to be, I am enthusiastic about the opportunity of the Pixel 11 having face unlock in all lighting circumstances. I am curious to see how nicely this technique works in apply and if it would lastly make face unlock a viable choice for me in darker environments.
