ABSTRACT:
An apparatus for displaying a 3-D image has a projector, and a projection controller. The projector has a projection optical system, and projects a series of 2-D images on different projected-positions in a depth direction, in order, by using light passing through the projection optical system. Each 2-D image is formed on the basis of section-views of a 3-D object in the depth-direction. The projector repeatedly and successively projects the series of 2-D images so as to cause an afterimage-effect. In the present invention, the projection controller adjusts a projection-timing of the series of 2-D images, and controls the projection optical system in accordance with the projection-timing so as to focus each 2-D image and maintain a magnification of the series of 2-D images constant.
