While a ball is rising, a point of attention of a virtual camera is set at the current position of the ball. At the instant when the movement of the ball is changed from rising to falling, the point of attention of the virtual camera is moved from the position of the ball to the position of the shadow of the ball. While the ball is falling, the point of attention of the virtual camera is set at the position of the shadow of the ball. Thus, in a baseball game or the like, a game image capable of providing a realistic feeling to the player and also allowing the player to grasp an area below the ball before the ball drops on the ground can be generated.
