Abstract
Intersection guide systems, methods, and programs acquire a degree of approach of a vehicle to an intersection ahead of a vehicle and display a guide image at a position of the intersection superimposed on a forward scene ahead of the vehicle. The systems, methods, and programs set, as a position of superimposition of the guide image, an intersection position within the forward scene when the degree of approach is less than a threshold. The intersection position corresponds to a registered position registered in map information as the position of the intersection. The systems, methods, and programs set, as the position of superimposition, a straight-line position within the forward scene when the degree of approach is equal to or more than the threshold. The straight-line position corresponds to a position on a straight-ahead line that is a straight line extending in a travel direction of the vehicle from the vehicle.
