An operation input reception unit (201) receives an operation input for a virtual vehicle. A running condition managing unit (203) manages the running conditions of the virtual vehicle based on the received operation input. An acceleration calculation unit (205) calculates an acceleration in a front or back direction caused by an inertia force in a case where a managed running condition is acceleration/deceleration, and calculates an acceleration in the left or right direction caused by a centrifugal force in a case where a managed running condition is turning. A meter producing unit (206) produces a meter image showing the direction and level of acceleration based on the acceleration calculated by the acceleration calculation unit (205). A display control unit (207) synthesizes a view field image produced by an image producing unit (204) and the meter image produced by the meter producing unit (206), and displays the image on an external monitor or the like.
