Three-dimenional image photographing apparatus and method having deflection means, apparatus and method for displaying three dimensional image, and apparatus and method for converting three-dimenional image display position

摘要

Image information necessary to display a three-dimensional image of an object in a space is acquired with a simple structure, and a three-dimensional dynamic image in a true sense is displayed with a simple structure. Part of light from an object ( 10 ) falls on a polarizer ( 11 ). The polarizer ( 11 ) passes the component of the incident light polarized at a predetermined angle to the surface of the polarizer ( 11 ) and allows the component to emerge from the polarizer ( 11 ) as parallel light perpendicular to the surface of the polarizer ( 11 ). The parallel light passes through a condenser lens ( 12 ), a pinhole member ( 13 ), and a condenser lens ( 14 ) and falls on a CCD ( 15 ). The angle of incident light selected by the polarizer ( 11 ) can be changed with time. Therefore, the image information outputted from the CCD ( 15 ) is a set of items of two-dimensional image information including the direction of imaging changing with time and is necessary to display a three-dimensional image of an object in a space.
