Camera-equipped stylus pen cap

摘要

A stylus pen cap has at least one camera disposed at least partially therein. The pen cap can further include a light source (such as an infrared light source) that directs light outwardly of the pen cap to the stylus. The pen cap can further include an electrical connector that operably couples to the camera(s) and conveys captured-image data to an outboard device of choice. The pen cap can include a pocket clip that comprises the electronic connector. The pocket clip can include a flexible joint (such as but not limited to a universal joint) to thereby permit the camera(s) to be oriented and aimed as desired even while electrically connected to an outboard device.
