Method and apparatus for displaying 3d images

摘要

The invention relates to a method for displaying three-dimensional images. In the method light beams (LSUBe/SUB) are associated to several different screen points (P) of a screen ( 20 ). The light beams (LSUBe/SUB) produce different views associated to different emission directions (E). The emission directions (E) are associated to the individual screen points (P). The light beams (LSUBe/SUB) are generated by projecting light beams (LSUBd/SUB), according to the angle of the adjacent emitting directions. According to the invention, light beams (LSUBe/SUB) without viewing direction information are generated, essentially simultaneously, with pixels (CSUBd/SUB) having different co-ordinates. These pixels (CSUBd/SUB) are pixels of a two-dimension display ( 50 ), and they are associated to different emitting directions (E) of the appropriate screen points (P). The light beams (LSUBe/SUB) produced by the pixels (CSUBd/SUB) of the display ( 50 ) with different co-ordinates are imaged simultaneously in different deflection directions (D), as a function of the co-ordinates of the pixels (CSUBd/SUB) producing the light beams (LSUBe/SUB). The subject of the invention is an apparatus implementing the above method.
