<P>PROBLEM TO BE SOLVED: To provide a visual feedback system to be connected between a game host system and an optical gun device. <P>SOLUTION: The visual feedback system is used for extracting a bullet falling point signal or bullet coordinate signal sent from the optical gun device to the game host. When the extracted signal is the bullet falling point signal, a control circuit calculates the bullet coordinate signal by using the horizontal synchronizing signal H<SB>-</SB>Sync and the vertical synchronizing signal V<SB>-</SB>Sync of video signals. Coordinate data are sent to an image synthesizing circuit and the image synthesizing circuit synthesizes a sighting point cursor at a position corresponding to the bullet coordinate data of the video signal transmitted from the game host and outputs a synthesized image on a display screen. <P>COPYRIGHT: (C)2003,JPO |
