Document Type and Number:
Japanese Patent JP3183632
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an image creating device and information storage media which can create an image suitable to a game play by making a virtual camera follow a displayed object.
SOLUTION: A virtual camera 20 follows the movement of a subject character 30, and an angle of field θ of the virtual camera 20 is changed based on position coordinates of the subject character 30 and a ball 40. When a distance D between the subject character 30 and the ball 40 becomes shorter, the angle of field θ becomes longer, and the distance becomes longer, the angle of field becomes shorter. This allows always to know an information around the ball 40 in detail. When the distance D becomes shorter than a threshold value (Dth), the angle of field θ is fixed to (θ fix) to prevent image distortion. The virtual camera 20 is faced to the direction from the subject character 30 to the ball 20 so that the ball is always placed around the center of a screen. The first and second displayed object become the first and second characters in a match game, and become character items in a role playing game.
