ABSTRACT:
A system, method and medium tracks a motion of a subject using a laser by synchronizing an incident axis of the input image with an exit axis of the laser in order to radiate the laser based on an input image. The system includes a half mirror to reflect a predetermined amount of incident light and to transmit a remaining amount of the incident light, an image input unit to input an image reflected from the half mirror, a position identifying unit to identify a position of a first subject included in the input image, and a target tracking unit to track the first subject with reference to the identified position by radiating a laser transmitted through the half mirror onto the first subject along an axis from the half mirror and onto the first subject.
