  • Publication number: 20100164702
    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.

  • Publication number: 20070229557
    Abstract: An image display unit has a display region with a higher resolution than a number of pixels of an image. A base information storage unit stores viewing position information of a viewer and size information of the display region. A wide-angle transformation unit calculates a central area including a viewing center of the viewer of the display region using the viewing position information and the size information, divides the image into a first pixel area corresponding to the central area and a second pixel area corresponding to a peripheral area other than the central area, and transforms the first pixel area and the second pixel area by magnifying. A magnification ratio of the first pixel area is less than a magnification ratio of the second pixel area. The image display unit displays an image including the transformed first pixel area and the transformed second pixel area.
