1. An intersection guide system comprising:

  • a memory storing a program; and

    a CPU that, when executing the program;

    acquires information on a path of a vehicle;

    acquires a travel direction of the vehicle at a guide intersection ahead of the vehicle on the basis of the information on the path;

    causes a display state on a display to transition from a first display state to a second display state in the case where a degree of approach of the vehicle to the guide intersection becomes equal to or more than a threshold;

    in the first display state, causes the display to display a guide image that represents the travel direction as superimposed on a portion of a forward scene ahead of the vehicle above an image of the guide intersection, and causes the display to display a connection line image as superimposed on the forward scene, the connection line image connecting between the image of the guide intersection in the forward scene and the guide image; and

    in the second display state, causes the display to display the guide image as superimposed on the image of the guide intersection in the forward scene, a shape of the guide image superimposed on the image of the guide intersection in the second display state being either (i) congruent to a shape of the guide image displayed on the forward scene in the first display state or (ii) proportionally enlarged relative to the shape of the guide image displayed on the forward scene in the first display state.
