Due to the small size, high accuracy, and easy integration of tof camera, it has been used in smartphones since 2014. Since 3D imaging and sensing had not been realized at that time, it was only a single point or small array ranging (1D dToF solution). The main applications are autofocus, proximity detection, and human presence detection. In terms of 3D ToF, face recognition, gesture recognition, and enhancement Real applications have become the driving force for growth.
ToF camera has now been greatly improved, with a resolution of up to VGA (640 pixels x 480 pixels) or even higher. At present, smartphones are the main application field of ToF in consumer electronics.
