Abstract
An electronic pen includes a projector configured to generate a virtual code pattern, a light-emitting unit configured to emit light to a detection area, a light-receiving unit configured to detect light reflected from the detection area, and a code processor configured to control the projector, the light-emitting unit, and the light-receiving unit. The code processor is configured to, when a code pattern is detected in a portion of the detection area, generate the virtual code pattern, which corresponds to a remaining portion of the detection area. The projector is configured to output the virtual code pattern to the remaining portion of the detection area.
