There are three main applications of ToF by smartphones. One is human detection including face recognition, which can help improve payment methods; the other is mobile phone photography optimization, especially the one that can improve the entire photo by more accurately judging the depth of field.Third, with the development of VR and AR, ToF with good perception can help mobile phones provide corresponding in-depth information.
The application of ToF technology for smart phones has been developed for some time. As early as 2014, ToF technology was used in the front distance sensor of smartphones. It actively emits photons through the transmitter and returns to the receiver to receive when encountering obstacles. It is mainly used for single-point optical ranging, that is, mainly in automatic Play a role in focusing and proximity detection.
Until 2017, the iPhone X front structured light module opened the era of 3D imaging, and the ToF industry chain applied to 3D perception was developed. With the development of 3D perception in the market, ToF will release greater potential.
