Abstract
A screen hologram image is reproduced on or near a plane of a hologram plate. A dynamic image is displayed at a position crossing an optical path of light beam for illumination to view a dynamic image on the screen hologram image. By using a plurality of apparatuses having the above-mentioned structure, planes of hologram plates are put without overlapping or with partial or overall lapping so that planes of master hologram images are arranged at different or the same positions in space. Thus, a dynamic image is displayed for right and left eyes for stereovision. Color display is possible. Further, an image is displayed in correspondence to a change in visual point in vertical direction or in depth direction. Thus, in an image display apparatus, a dynamic image is viewed for each of the eyes by using a hologram.
