<P>PROBLEM TO BE SOLVED: To provide a 3D pointer device stereoscopically displays a pointer video image at a 3D position specified in a stereoscopic video image displayed in a 3D display device, especially, to provide a 3D pointer device which enables a lecturer to point accurately an object in an image with the pointer displayed in 3D for a 3D video image observed by a number of viewers. <P>SOLUTION: A 3D pointer device comprises a pointer device 6 which specifies a display position of a pointer image 10 to be displayed in a 3D display surface 1; a depth instruction device which adjusts a depth position of the pointer image; a point position detecting device 8 which detects a 3D position of the pointer image 10 displayed on the 3D display surface 1; a 3D pointer video image signal generating device which generates a 3D video image signal of the pointer image 10 for supplying to a video image supplying device; and the video image supplying device which mixes the 3D video image of the pointer image and a 3D video image of an original video image to synthesize a 3D video image signal for projection to be supplied to a 3D projection device 4. <P>COPYRIGHT: (C)2012,JPO&INPIT |
