To make a crew member of a motor vehicle surely and visually recognize the location of the occurrence of event in front, when three-dimensionally displaying objects such as buildings and natural objects on a map display screen.
A transmission/reception part 11 receives event information, including the location of occurrence of the event. A part 12 for detecting the location of one's own motor vehicle computes the location of the motor vehicle. A storage part 13 stores map data for two-dimensionally and three-dimensionally displaying the objects, such as buildings and natural objects on a display 15. On the basis of the location of occurrence of the event, the location of the motor vehicle, and the map data, a determining part 31 determines whether the location of occurrence of the event is shielded by the objects, when three- dimensionally displaying a map including the objects on the display 15. A transmitting display part 32 performs the transmitting display of the objects on the display 15, when it is determined that the location of occurrence of the event will be shielded by the objects. A distance computing part 33 computes the distance from the location of the motor vehicle to the location of the occurrence of the event.
