NAVIGATION DEVICE AND NAVIGATION METHOD |
摘要 |
A navigation device and the like capable of preventing a user from falsely recognizing an intersection to take a turn even when another intersection is present near a guidance target intersection. The navigation device that performs route navigation by displaying a guiding symbol superimposed on a photographed image includes: an adjacent intersection detection unit that calculates a distance between a guidance target intersection and an intersection adjacent to the guidance target intersection; and a guidance display control unit that controls guidance details to be displayed. The guidance display control unit sets timing for indicating a path to be taken at the guidance target intersection by using the guiding symbol based on the distance between intersections calculated by the adjacent intersection detection unit.
