Abstract
A display apparatus that can surely make an image reach an observer's pupil without imposing a burden on the observer. The apparatus includes: an eyepiece optical system; and an image display apparatus including an image forming apparatus and a transfer optical system. The eyepiece optical system and the image display apparatus are spatially separated from each other, the eyepiece optical system forms an image from the transfer optical system on a retina of an observer, the image display apparatus further includes a first position detection apparatus that detects a position of the eyepiece optical system, a second position detection apparatus that detects a position of a pupil of the observer. On the basis of detected positional information of the eyepiece optical system and the pupil, the transfer optical system is controlled such that the image incident from the image forming apparatus reaches the eyepiece optical system.
