NAVIGATION DEVICE, INFORMATION DISPLAY DEVICE, NAVIGATION METHOD, NAVIGATION PROGRAM, AND RECORDING MEDIUM

摘要

A generating unit (104) of a navigation device (100) generates a midair route-guidance display image, serving as a strip-shaped route display image that extends along a route, displayed at a predetermined height from the road surface on the basis of information relating to the current position acquired by a current-position information acquiring unit (101), route information acquired by a route information acquiring unit (102), and node information and link information stored in a storage unit (103). A display unit (106) displays the generated midair route-guidance display image by superimposing the midair route-guidance display image on a front image of a movable body (vehicle in which the navigation device is installed) on the route acquired by an image acquiring unit (105), or projects the midair route-guidance display image onto a front window.
