Display control device, display method, and storage medium
A vehicle display control device, which displays a predetermined image at a display region showing a foreground of a vehicle, includes a memory, and a processor connected to the memory. In a case in which a change operation that changes an advancing direction of the vehicle is planned, the processor displays at least one directional image, which indicates an advancing direction after the change, in the display region, and changes a number of the directional images during a time period until the vehicle reaches a change operation point at which the change operation is to be carried out.
1. A vehicle display control device that displays a predetermined image at a display region showing a foreground of a vehicle, the vehicle display control device comprising:
a memory; and
a processor coupled to the memory,
wherein the processor is configured to:
display, on the display region, a directional image that indicates an advancing direction being planned in a case in which at least one of a distance or a time from the vehicle to a change operation point is less than or equal to a predetermined threshold value; and
gradually increase a number of directional images displayed as the vehicle approaches the change operation point at which a change operation is to be carried out such that each subsequent directional image moves continually over time along a future path of the vehicle toward the change operation point and stops at a point along the future path that is ahead of the change operation point and behind the directional image that is displayed just before.
2. The vehicle display control device of claim 1 , wherein the processor is further configured to increase the number of directional images during the time period until the vehicle reaches the change operation point.
3. The vehicle display control device of claim 1 , wherein the processor is further configured to display a first directional image such that the first directional image moves from a near side toward a far side of the display region, along a path from the vehicle to the change operation point.
4. The vehicle display control device of claim 1 , wherein, after the vehicle has passed the change operation point, the processor is further configured to display a first directional image such that the directional image moves in the advancing direction after the change operation.
5. The vehicle display control device of claim 1 , wherein the change operation point is an operation point at which a turn signal is to be turned on in order to change the advancing direction of the vehicle.
6. The vehicle display control device of claim 1 , wherein the change operation point is an operation point at which a steering operation is to be carried out in order to change the advancing direction of the vehicle.
7. The vehicle display control device of claim 1 , wherein
the display region is a projected plane that is projected at a vehicle front side of a driver's seat by a head-up display device, and
the processor is further configured to specify the change operation point from the foreground of the vehicle viewed through the display region, and display a first directional image at a position corresponding to the change operation point in the display region.
8. A display method that displays a predetermined image at a display region showing a foreground of a vehicle, the display method comprising:
displaying, on the display region, a first directional image that indicates an advancing direction being planned in a case in which at least one of a distance or a time from the vehicle to a change operation point is less than or equal to a predetermined threshold value; and
gradually increasing a number of directional images displayed as the vehicle approaches the change operation point at which a change operation is to be carried out such that each subsequent directional image moves continually over time along a future path of the vehicle toward the change operation point and stops at a point along the future path that is ahead of the change operation point and behind the directional image that is displayed just before.
