System and method for tracking an object during video communication

摘要

An object is tracked with a camera that is sensitive to both visible and invisible light. An invisible light reflector attached to the object may reflect a target of invisible light, which is provided by an invisible light emitter. The camera processes the invisible light and moves the field of view of the camera so that the object is centered within the field of view. The camera may also zoom the field of view to a desired magnification level.
