Display control apparatus, display device, and display control method

A display control method for controlling image display of a display device that is mounted in a vehicle and causes a viewer who is an occupant of the vehicle to visually recognize an image, the display control method comprising:

• a step of performing wide-area display control to, when a distance from the vehicle to an intersection ahead of the vehicle is more than a first threshold under a driving situation in which the vehicle needs to turn left or right at the intersection, display, at a first scale, a first map that is a bird's-eye view of a surrounding area including an area ahead of the vehicle, and display an own vehicle mark having a predetermined shape capable of indicating a position of the vehicle and indicating a traveling direction of the vehicle to overlap with a first road on the first map corresponding to a road where the vehicle is actually traveling;
• and
• a step of performing narrow-area display control to, when the vehicle further approaches the intersection and the distance from the vehicle to the intersection becomes equal to or less than the first threshold, erase the own vehicle mark, display, at a second scale larger than the first scale, a second map that is a bird's-eye view of the vicinity of the intersection, and display a guide mark having a shape identical or similar to the predetermined shape of the own vehicle mark and indicating a traveling direction of the vehicle at a first position of the first road on the second map to overlap with the first road by adjusting the scale so as not to interfere with visual recognition of the intersection on the second map.
