Image input apparatus and image display apparatus

摘要

An image display apparatus has an image display for displaying a parallax image, and a display optical system for guiding light from the image display to the position of the exit pupil. The exit pupil is spatially and temporally divided into a plurality of areas, a passing beam to each area is controlled, and control is effected on switching between parallax images on the image display means corresponding to passing beams through the respective areas of the exit pupil, whereby a plurality of parallax images are perceived by a single eye of an observer. <IMAGE>
