<P>PROBLEM TO BE SOLVED: To improve visibility by allowing an observation object to be tracked by an observation position even when the observation position of an observer changes. <P>SOLUTION: An observation position tracking device includes: a light source for emitting light; an observation object to be observed by an observer; a light collecting part for collecting reflecting light in which light from the light source is reflected on the observer side; a light position detection part for detecting a position of the reflecting light collected by the light collecting part; a support part for supporting the light source, the observation object, the light collecting part, and the light position detection part; a drive part for moving a position of the support part with respect to a fixed part; and a control unit for allowing the drive part to move the support part so that a position of the reflecting light detected by the light position detection part comes close to a set reference position. <P>COPYRIGHT: (C)2012,JPO&INPIT |
