Apparatus and method for photographing three-dimensional image, apparatus and method for displaying three-dimensional image, and apparatus and method for converting three-dimensional image display position

摘要

The present invention makes it possible to acquire image information required for displaying a three-dimensional image of an object in a space with a simple configuration and to achieve display of a stereoscopic dynamic image in a true sense with a simple configuration. Light from an object ( 10 ) impinges upon a deflecting plate ( 11 ). Among the incident beams of light, the deflecting plate ( 11 ) allows beams of light at a predetermined angle to the plane of the deflecting plate ( 11 ) to pass, the beams exiting as parallel beams of light perpendicular to the plane of the deflecting plate ( 11 ). The light passes through a converging lens ( 12 ), a pinhole member ( 13 ), and a converging lens ( 14 ) to impinge upon a CCD ( 15 ). An angle of incident light selected by the deflecting plate ( 11 ) is sequentially changed as time passes. Therefore, image information output by the CCD ( 15 ) becomes plural pieces of two-dimensional image information for which the photographing direction changes as time passes and which serve as image information required for displaying a three-dimensional image of the object in a space.
