The newly announced LG G3 smartphone features an intriguing piece "Laser Auto Focus measures the distance to the subject using laser technology. Laser Auto Focus allows for improved focusing speed and object detection in low-light situations." I was told that this AF utilizes STM's SPAD-based ToF range finder. A similar SPAD device is also used in a low-end Bosch laser distance measurer PLR15.
If true, the SPAD ToF technology finds its way to more and more mass market devices: first to ST proximity sensor, then to Bosch distance meter, and now to LG G3 flagship smartphone.
