Selfie camera on LG G8 ThinQ to offer fast, accurate facial recognition

Spread the love

A press-release issued Thursday by LG (when it was still Wednesday night in the states) says that LG and semiconductor firm Infineon will partner up to equip the LG G8 ThinQ with a front-facing Time of Flight (ToF) camera. Instead of using algorithms to compute the distance between the subject of a selfie and the lens, ToF tracks the time it takes for an infrared signal to bounce off the subject and return to the source.

ToF is also cheaper and easier to manufacture than structured lighting. With the later system, a pattern or multiple patterns are projected on a subject while the camera is recording. Since the software knows what the patterns look like on a flat surface, it can make a 3D map of a person’s face by making computations about the distortions of the projected patterns.
