Abstract: An automotive display system includes an image projection unit and an angle information acquisition unit. The image projection unit projects a light flux including an image including a display object toward one eye of an image viewer. The angle information acquisition unit acquires at least one of vehicle angle information and external environment angle information. The vehicle angle information relates to an angle of at least one of an attitude and a heading of a vehicle carrying the image viewer. The external environment angle information relates to an angle of a background object at a target position of the display object in a background of an external environment of the vehicle. The image projection unit changes an angle of the display object in the image based on at least one of the vehicle angle information and the external environment angle information acquired by the angle information acquisition unit.
