An image generating system and information storage medium for generating an image preferable for a game in which a virtual camera follows a displayed object. The angle of view theta of the virtual camera is changed based on the coordinates of the player's game character and ball while causing the virtual camera to follow the player's game character. As the distance D between the player's game character and the ball decreases or increases, the angle of view theta is increased or decreased. Thus, the player can clearly grasp information about things around the ball. If the distance D becomes shorter than a threshold value Dth, the angle of view theta is set at a fixed value thetafix. This prevents an image from being distorted. The ball is always displayed on the screen in the central part thereof by directing the virtual camera in a direction from the player's game character toward the ball. The first and second displayed objects represent respectively a first and second game characters in a fighting game and a character and item in a role-playing game.

A wide-angle lens system comprises, sequentially from the object side to the image side: a first lens element, a second lens element, a third lens element, an aperture and a fourth lens element.

Therefore, it is very suitable for use in the monitor and vehicle-related lens system.
