US 9,519,146 B2 · Virtual image display apparatus

Abstract

Image light is formed of light flux components having a diameter of, e.g., 3 mm or smaller. The image light is then caused to be incident on the iris of an eye to form an image in the form of a virtual image. The position where the principal rays of the light flux components that form the image light intersect one another is set to be a position shifted from the position of the iris of the eye toward the retina. The range of the light flux components that reach the retina can thus be changed in accordance with the motion of the eye. As a result, in accordance with a change in the line of sight that occurs when a wearer moves the line of sight in a specific direction, the image light can be so controlled that only image light components in the specific direction reach the retina of the eye.

Dependent claims

A virtual image display apparatus comprising an image formation unit that causes image light having a predetermined light flux diameter to be incident on the iris of a user's eye so as to allow the user to visually recognize an image in the form of a virtual image,

wherein the image formation unit, when forming the image light, sets a position where principal rays of light flux components of the image light incident on the iris of the eye intersect one another to be a position (i) shifted away from an intended iris position where the iris of the eye is to be disposed toward a projection position where the retina of the eye is to be disposed but (ii) upstream of an intended center position corresponding to the center of pivotal motion of the eye.

Dependencies are inferred from the claim text.
