Image Display Unit and Electronic Glasses
First Claim
1. An image display apparatus for projecting an image on a retina through a pupil of an eye by a Maxwellian view, comprising:
- a point light source;
a display section for emitting a display image light from a display screen using the point light source;
a light focusing section for focusing the display image light from the display section; and
a light source driving section for detecting a position of the pupil and automatically moving/controlling the position of the point light source such that a light focusing convergence point for the Maxwellian view is positioned within the pupil.

Abstract
With a simple structure, the light focusing convergence point for the Maxwellian view and the position of the pupil can be easily and quickly matched to each other in a steady manner and thus it is possible to obtain a sharp image by the Maxwellian view. When the position of the point light source 11 is automatically adjusted by the light source driving apparatus 14 using the parallel light as shown in Portion (a) of FIG. 1 as the display image light incident on the convex lens 13 (or HOE) or using the spherical wave light instead of the parallel light as shown in Portion (b) of FIG. 1, the position of the light focusing convergence point A for the Maxwellian view with respect to the position of the pupil is easily and quickly adjusted in a steady manner. Further, as with an optical path length L of the entire optical system, as shown in Portion (b) of FIG. 2, which uses the spherical wave light, it is possible to shorten the entire optical system by distance M when compared to the case, shown in Portion (a) of FIG. 2, which uses the parallel light.
