Abstract
A three-dimensional image reconstructing apparatus for reconstructing a three-dimensional image and permitting the three-dimensional image to be observed at an observation position by use of an image display for displaying image information, a space optical modulator for forming a fine aperture, an optical system disposed near the space optical modulator, and a controller for controlling the image display and the space optical modulator so that some rays outgoing through the fine aperture of the space optical modulator and the optical system out of rays from the image information displayed on the image display pass a predetermined point in a three-dimensional space within a fixed period, wherein a distance between two closest rays passing the predetermined point and reaching the observation position is determined based on a diameter of a pupil of an observer.
