Abstract
An object is identified with a camera that is sensitive to both visible and invisible light. An invisible light illuminator attached to the object may project a target of invisible light, which may either be generated by the illuminator or reflected from a separate invisible light source by the illuminator. The system processes the invisible light and identifies the object based on identity characteristics extracted from the invisible component. The system may then adapt its operation to settings associated with the object.
