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.

An automotive display system includes a frontward information acquisition unit, a position detection unit and an image projection unit. The frontward information acquisition unit acquires frontward information. The frontward information includes information relating to a frontward path of a vehicle. The position detection unit detects a position of one eye of an image viewer riding in the vehicle. The image projection unit generates a first virtual image at a corresponding position in scenery of the frontward path based on the frontward information acquired by the frontward information acquisition unit and projects a light flux including an image including the generated first virtual image toward the one eye of the image viewer based on the detected position of the one eye. The first virtual image has a size corresponding to at least one of a vehicle width and a vehicle height.
