<p><P>PROBLEM TO BE SOLVED: To prevent an indication index and an object from being obstructed when the indication index such as an underline is given to the object indicated by a pointer. <P>SOLUTION: A projection control device 1 makes a projector 5 project a projection image Pi based on first image information and obtains second image information by capturing the projection image Pi by a camera 6. The projection control device 1, based on the first image information and the second image information, detects an indication to the object included in the first image information, and extracts the indicated object. Afterward, the projection control device 1 generates a region corresponding to the extracted object. When the projection control device 1 consecutively detects an indication by the pointer and the like in the generated region during a first time, the projection control device 1 makes the projector 5 project an image wherein the indication index is added to the indicated object. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
