1. A three-dimensional image display game system for use with a display for displaying an object in a three-dimensional space according to a stored program, comprising:

  • an operation controlling device including an operating member having a base end rotatably supported and a free end operable by an operator, so that image data is caused to be varied in accordance with movement of said operating member, said operation controlling device includes an inclination amount data output detector which detects an inclination amount of said operating member, including a first direction component and a second direction component, to output inclination amount data; and

    image processing apparatus including;

    direction determining circuitry operable to determine a direction that corresponds to an inclination direction of said operating member based on the inclination amount data;

    moving object direction determining circuitry which determines a moving direction of the object in three-dimensional space based upon said direction determined by said direction determining circuitry and a point of view angle at which the object is being viewed by said operator in three-dimensional space wherein a direction in which said operating member must be moved to cause forward movement of the object is offset from a forward direction of said operation controlling device by an angle substantially corresponding to said point of view angle;

    moving amount determining circuitry operable to determine a moving amount of the object on said display;

    an object position determining circuitry operable to determine a position of the object in the three-dimensional space in accordance with the moving direction determined by the moving direction determining circuitry and the moving amount determined by said moving amount determining circuits; and

    image data generating circuitry for displaying the object at a position determined by said object position determining circuitry.
