In order to catch up with Apple iPhone X TrueDepth technology, Android devices are now looking to introduce same technology in their devices. According to the KGI analyst Ming-Chi Kuo, the first models are not coming before 2019.
Kuo says that the first Android smartphone to have 3D-sensing capabilities will be launched by Huawei in 2019. The company will be starting light solutions same as Apple’s TrueDepth camera system which is present in iPhone-X. This will move to cheap small time-of-flight sensors by a second or third quarter of the next year as said by Kuo. The models which are having structured light technology may get replaced by TIF sensor within three to six months of mass production. Other smartphone makers may also use ToF technology to develop their own facial recognition camera systems.
Kuo said that ToF may become the Android main facial recognition solution and this may get produced in a mass. Apple is the first smartphone maker to develop depth-sensing camera technology after launching iPhone-X last year. It specialized the camera system with a dot projector, flood illuminator, infrared and color cameras and advance learning algorithms for facial recognition solution known as FaceID.
To map a user face accurately, TrueDepth projects about 30,000 dots in a pattern by using a vertical-cavity surface-emitting laser(VCSEL) in the infrared spectrum. In ToF it generates depth maps by calculating the time it takes for laser pulses by bouncing off an object’s surface.
Kuo predicted that Apple is having about two-year head start over Android camp in 3D sensing technology. The suppliers of VCSEL and optical filters said that they are unlikely to produce till late 2019.
