DISPLAY SYSTEM, DISPLAY METHOD, AND DISPLAY PROGRAM
First Claim
1. A display system for generating and displaying an arrow object superimposed on an actual image of a road ahead of a vehicle, the display system comprising:
- a controller that;
accesses information about a lane change route for guiding the vehicle when changing from a travel lane to a recommended lane, the travel lane being a lane in which the vehicle is currently traveling, the recommended lane being a lane that allows the vehicle to enter a lane in which the vehicle is to travel after passing through a road junction ahead of the vehicle;
generates and displays a travel lane part of the arrow object, the travel lane part being displayed as a superimposed image on the travel lane;
generates and displays a crossing part of the arrow object the crossing lane part being displayed as a superimposed image traversing from the travel lane to the recommended lane;
generates and displays a recommended lane part of the arrow object, the recommended arrow lane part being displayed as a superimposed image on the recommended lane; and
changes a shape of the displayed arrow object such that, as a remaining distance from a current position of the vehicle to the junction becomes smaller, a distance of a directional component along the travel lane for at least one of the travel lane part, the crossing part, and the recommended lane part is shortened.

Abstract
Display systems, methods, and programs generate and display an arrow object superimposed on an actual image of a road ahead of a vehicle. The systems, methods, and programs access information about a lane change route for guiding the vehicle when changing from a travel lane to a recommended lane. The systems, methods, and programs generate and display a travel lane part of the arrow object, a crossing part of the arrow object, and a recommended lane part of the arrow object, each as a superimposed image on the recommended lane. As remaining distance from a current position of the vehicle to the junction becomes smaller, a distance of a directional component along the travel lane for at least one of the travel lane part, the crossing part, and the recommended lane part is shortened.

11. A computer-readable storage medium storing a computer-executable display program usable to generate and display an arrow object superimposed on an actual image of a road ahead of a vehicle, the program comprising:
-
instructions for accessing information about a lane change route for guiding the vehicle when changing from a travel lane to a recommended lane, the travel lane being a lane in which the vehicle is currently traveling, the recommended lane being a lane that allows the vehicle to enter a lane in which the vehicle is to travel after passing through a road junction ahead of the vehicle; instructions for generating and displaying a travel lane part of the arrow object, the travel lane part being displayed as a superimposed image on the travel lane; instructions for generating and displaying a crossing part of the arrow object the crossing lane part being displayed as a superimposed image traversing from the travel lane to the recommended lane; instructions for generating and displaying a recommended lane part of the arrow object, the recommended arrow lane part being displayed as a superimposed image on the recommended lane; and instructions for changing a shape of the displayed arrow object such that, as a remaining distance from a current position of the vehicle to the junction becomes smaller, a distance of a directional component along the travel lane for at least one of the travel lane part, the crossing part, and the recommended lane part is shortened. - View Dependent Claims (12, 13, 14, 15)
