A position of an observer in a stereoscopic observing region is detected by a position detecting unit. A right-eye image and a left-eye image which are seen from the detecting position are formed by an image forming unit and displayed on a display. By setting an aperture position of a projection optical system, the right-eye image is projected to the right-eye position of the observer and the left-eye image is projected to the left-eye position, thereby allowing a stereoscopic image to be observed. Further, an aperture is set so as to project the right-eye image or left-eye image to a position different from the detecting position of the observer, thereby allowing a same image to be seen to both eyes of another observer and allowing a two-dimensional image to be observed.

[ What is claimed is:] [1.] An image display apparatus for recognizing a stereoscopic image by a parallax of both eyes, comprising:a position detecting unit for detecting a position of an observer existing in a stereoscopic observing region;an image forming unit for forming a right-eye image and a left-eye image seen from the detecting position of said observer;a display for displaying the right-eye image and a left-eye image formed by said image forming apparatus;a projection optical unit for projecting the display images of said display to the detecting position of said observer by setting an aperture position; andan aperture control unit for controlling a position and a size of the aperture of said projection optical unit on the basis of the detecting position of said observer in a manner such that at least said right-eye image is projected to a position including a right eye of said observer and said left-eye image is projected to a position including a left eye of said observer, thereby allowing said observer to observe a stereoscopic image.
