<P>PROBLEM TO BE SOLVED: To accurately recognize a gesture by the movement even if using fingers or arms. <P>SOLUTION: A gesture recognition device detects luminescent point coordinates of a graphic drawn by a gesture from an image frame imported from a camera 4, and determines whether the luminescent point coordinates are included in a first area Ea or a second area Ec in the image frame. The gesture recognition device sets a finger gesture mode when the luminescent point coordinates are included in the first area Ea, and sets a camera tracking mode when the luminescent point coordinates are included in the second area Ec. In the finger gesture mode, the graphic by the finger gesture is recognized based on the image data. On the other hand, in the camera tracking mode, a pan and tilt drive unit 5 controls a pan and tilt angle of the camera 4 to set the imaging direction of the camera 4 so as to track the movement of a user's arm, and recognizes the graphic based on the tracked trajectory. <P>COPYRIGHT: (C)2012,JPO&INPIT |
