<P>PROBLEM TO BE SOLVED: To detect a moving body in a picked-up image by simple technique to allow tracking. <P>SOLUTION: A difference image forming module 110 generates difference image data by taking difference between adjacent frames on a time axis on image data picked up by a CCD camera 22 and provided by a virtual robot 43. A center-of-gravity computing module 111 computes the center-of-gravity position of the difference image data and sends the information to an action model library 90. The action model library 90 determines action facing or approaching the center-of-gravity position detected immediately before when the moving body disappears from the difference image data, for instance. A tracking signal processing module 73 sends a servo command value for manifesting action, to corresponding actuators 28<SB>1</SB>-28<SB>n</SB>through the virtual robot 43 or the like based on an action command from an action changeover module 91. <P>COPYRIGHT: (C)2004,JPO |
