摘要： A three-dimensional image display method and apparatus wherein a three-dimensional image of an object is reproduced by three-dimensional display means (5101; ..) by displaying two-dimensional images at different depths and by varying the luminance of the images or portions thereof. The three-dimensional image is distributed to a plurality of observers (5102, 5103, 5104; ..) using a viewing zone distributing means (5105-5107 ;..) which distributes the viewing zone of the three-dimensional display means into a plurality of directions. The distributing means may comprise a plurality of partially reflecting mirrors (5105, 5106, 5107) or a combination of partially reflecting mirrors and optical components. A totally reflecting mirror may be substituted for the final partially reflecting mirror (5107). Alternatively the distributing means may comprise: a plurality of dichroic mirrors or dichroic prisms, or a combination thereof; a holographic optical element with a plurality of reflection angles or diffraction angles, a holographic optical element with a single reflection angle or diffraction angle, or a combination thereof; a prism array having an array of prisms with different refraction directions; a mirror array having mirrors with different reflection directions; or a refraction grating array having different gratings with different refraction angles.
