PURPOSE: To provide a game device using a head-mounted body, which can miniaturize the game device, and also, suppresses a rise of the cost, and moreover improves a response to the motion.
CONSTITUTION: This game device is constituted by containing an image display device 10, an angular velocity sensor 612, a head-mounted body provided with a loudspeaker 622, a game space arithmetic part 100 for executing an operation related to an advance of a game, and an image synthesizing part 200 which contains an angle arithmetic part 682 and generated image information outputted to the image display device 10. When a player changes his sight line direction, a time variation (angular velocity) in this direction is detected by the angular velocity sensor 612, and the varied sight line direction is calculated by the angle arithmetic part 682. Based on a result of this calculation, a coordinate transformation processing to a visual point coordinate system, subsequently, a clipping processing, a see-through projection conversion processing and a sorting processing are executed, and an image in the visual field direction of the player is outputted to the image display device 10.
