Patent ID: 8708498

Claim:
A display apparatus for vehicle comprising: an image projector configured to project a light flux including an image having a display object toward a one eye of an image viewer; and a position detector configured to detect the one eye of the image viewer, the image projector being configured to change a shape of the display object in the image on the basis of a position of the one eye detected by the position detector, moving subject parallax of the image viewer calculated from the position of the one eye detected by the position detector, and a depth presenting target position of the image, wherein when a distance from the image viewer to the depth presenting target position is assumed to be d 2 , and a movement distance of a detecting position of the one eye detected is assumed to be s 0 , the image projector changes the shape of the display object on the basis of one of two acute angles of a right triangle having a line segment of the d 2 and a line segment of the s 0 as an adjacent side and an opposite side.
