Display control device and display control method

A display control device for controlling a display device displaying a driver support image to have an overlap with a view from a driver seat in a vehicle or a live-action video in front of the vehicle, the display control device, comprising:

• a processor to execute a program;
• and
• a memory to store the program which, when executed by the processor, causes the processor to perform processes comprising:
• acquiring a current position of the vehicle and a traffic lane where the vehicle is currently located;
• acquiring feature data including information of a regulation in a traveling direction regarding a road in front of the vehicle;
• determining a travelable traffic lane along which the vehicle can travel in an intersection in front of the vehicle and a road ahead of the intersection or a branch point in front of the vehicle and a road ahead of the branch point based on the current position of the vehicle, a traffic lane where the vehicle is currently located, and the feature data;
• generating a video signal for displaying the driver support image to have an overlap with the travelable traffic lane or a video signal for displaying the driver support image to have an overlap with a region other than the travelable traffic lane;
• and
• outputting the video signal to the display device, wherein
• the driver support image having the overlap with the travelable traffic lane is an image having a width in a width direction of the traffic lane, extending in a direction in which the traffic lane extends, and linking the traffic lane where the vehicle is currently located and the travelable traffic lane ahead of the intersection or the branch point,
• the driver support image having the overlap with the region other than the travelable traffic lane is an image in which the travelable traffic lane can be distinguished according to a width and a length, and
• when there are a plurality of travelable traffic lanes in the road ahead of intersection or the branch point, the processor generates, in generating the video signal, a video signal for displaying the driver support image to have an overlap with each of the plurality of travelable traffic lanes or a video signal for displaying the driver support image to have an overlap with a region other than the plurality of travelable traffic lanes.
