Image generation apparatus, display system, image generation method, and recording medium

An image generation apparatus for use in a display system that projects an image onto a display medium of a vehicle to enable a user to visually recognize a virtual image of the image, the image generation apparatus comprising:

• a vehicle information acquisition that acquires vehicle position information and path information, the vehicle position information indicating a current location of the vehicle, the path information indicating a path along which the vehicle is guided to a destination;
• a map image generation that generates a map image of a vicinity of the current location in accordance with the vehicle position information acquired;
• a guide image generation that generates a guide image that indicates the path relative to the current location in accordance with the vehicle position information acquired and the path information acquired;
• an image composition that generates a composite image for projecting the guide image and the map image which have been generated, in a mode in which the guide image and the map image are associated with each other;
• and
• a display position setting that sets a display position of the guide image to enable the user to visually recognize a virtual image of the guide image in a position that overlaps a path point on the path,
• wherein the auxiliary image is overlaid on the position on the map image that corresponds to the path point at which the virtual image of the guide image is displayed.
