According to the patent documents, the system uses two laser bow that sends impulse at different angles. This allows the camera to instantly calculate and configure the distance to the object. If the sensors are separated, the device automatically switches to the standard automatic focus mode.
The main advantage of innovation is to eliminate widespread problems: shine from water, glass or metal surfaces. An additional laser beam increases the accuracy of determining the depth of the scene, which is particularly useful when moving.
The entire focus process takes part of a second that protects users from the need for manual configuration.
