Abstract
In a navigation device for providing a guide from an origin to a destination, a display section displays a guide image indicating the guide to the destination. A state acquisition section acquires a state outside a vehicle. A photographed guide generation section generates a photographed guide image, using a photographed image of a captured forward direction of the vehicle. A map guide generation section generates a map guide image, using map information. Based on the state outside the vehicle acquired by the state acquisition section, a state determination section determines which one of the photographed guide image and the map guide image is to be displayed by priority. Based on the determination made by the state determination section, a guide display control section allows the guide image including at least one of the photographed guide image and the map guide image to be displayed in the display section.
