The purpose of the present invention is to make it possible to appropriately suppress guidance that uses screen display. If an image acquired by an image acquisition unit 11 includes a direction that can be traveled in from an intersection in front of a vehicle and a guidance sign indicating a travel bearing, an image processing unit 12 extracts the direction indicated by the guidance sign from the image as an extracted direction. If, on the basis of a guidance route, the extracted direction, and direction information, a route guidance processing unit 14 determines a guidance direction that corresponds to the bearing in which the vehicle should travel at a guidance intersection and matches the extracted direction, the route guidance processing unit 14 does not display a guidance screen and outputs speech guidance regarding the guidance direction visible on the guidance sign. |
