Abstract
In an apparatus for displaying a three-dimensional image, an image display and a polarizing filter having an axis of easy transmission in a predetermined direction or an optically-active film having an optically-active portion at a predetermined position are combined together in a predetermined positional relationship, thereby easily displaying an image on the image display when a flat original image is prepared for forming the three-dimensional image and simplifying the structure of the apparatus with a reduced manufacturing cost. The apparatus for three-dimensionally displaying a planar image recorded on a polarizing film comprises a monochrome liquid crystal television screen which functions as a backlight source, a convex Fresnel lens for magnifying an image of the backlight source, an infrared illumination light source for illuminating a half of the face of an observer with infrared radiation, an infrared camera for capturing the illuminated image of the observer, and an interlaced-image synthesizing circuit which forms a binary-coded image obtained by the infrared television camera and its reversed image and interlaces the binary-coded image and reversed image to synthesize a signal.
