Method for controlling movement of viewing point of simulated camera in 3D video game, and 3D video game machine
First Claim
1. A 3D video game machine, comprising:
- a monitor provided at a specified height position of a casing of the game machine for displaying images;
a game control unit for controlling progress of a game;
a display control unit for generating a 3D image viewed from a viewing point of a simulated camera and for displaying said 3D image on a screen of the monitor;
head detecting means for detecting at least a position of the head of a game player located in a play area before the screen of the monitor in at least one linear direction in a 3D space relative to the screen of the monitor; and
viewing point changing means for moving the viewing point of the simulated camera to follow a displacing direction and a displacing amount of the detected position of the head.

Abstract
A 3D game machine includes a monitor for displaying images, a game control unit for controlling progress of a game, and an image control unit for generating and displaying a 3D image viewed from a viewing point of a simulated camera on a screen of the monitor. A transverse position and a height position of the head of a game player located in a play area before the screen of the monitor are detected using one ultrasonic transmitter and two ultrasonic receivers, and the viewing point of the simulated camera is so moved as to follow a displacing direction and a displacing amount of the detected position of the game player'"'"'s head, thereby allowing the viewing point of the simulated camera to follow free movements of the game player so that images viewed from the viewing point intended by the game player are actively displayed.

15. A method for controlling a movement of a viewing point of a simulated camera in a 3D video game executed in a 3D video game machine comprising a monitor provided at a specified height position of a casing of the game machine for displaying images and a game control unit for controlling the progress of a game, the method comprising the steps of:
-
generating a 3D image viewed from a viewing point of a simulated camera and displaying said 3D image on a screen of the monitor;
obtaining a position information of a game player'"'"'s head by causing head detecting means to repeatedly detect a position of the head of the game player standing in a play area before the screen of the monitor in at least one linear direction in a 3D space relative to the screen of the monitor; and
moving the viewing point of the simulated camera to follow a displacing direction and a displacing amount of the detected position of the bead.

16. A 3D video game machine, comprising:
-
a monitor provided at a specified height position of a casing of the game machine for displaying images;
a game control unit for controlling progress of a game;
a display control unit for generating a 3D image viewed from a viewing point of a simulated camera and for displaying said 3D image on a screen of the monitor;
head detecting means for detecting at least a position of the head of a game player located in a play area before the screen of the monitor in at least one linear direction in a 3D space relative to the screen of the monitor, the head detecting means including a sheet-shaped pressure sensor for detecting positions of both feet of the game player in at least one direction on a horizontal plane;
head position determining means for determining a position of the head in said at least one direction on the horizontal plane based on detected position information of the feet; and
viewing point changing means for moving the viewing point of the simulated camera to follow a displacing direction and a displacing amount of the detected position of the head by said head position determining means.
