<P>PROBLEM TO BE SOLVED: To display a three-dimensional image at an intended display distance, at an optimum condition, and with a simple and inexpensive configuration. <P>SOLUTION: The scanned type display-device optical system 10 includes a two-dimensional image forming element 11, a first condenser lens 12, a diaphragm 13, a second condenser lens 14, a one-dimensional scanner 15, a third condenser lens 16 and a diffuser 17. For the two-dimensional image forming element 11, a display device using a liquid crystal display, an organic EL display, or a digital micromirror device or the like can be used. An input parallactic image is switched at a high speed and displayed at time division. The one-dimensional scanner 15, by performing scan linked to the operation of the two-dimensional image forming element 11, projects the image of the two-dimensional image forming element 11 on the diffuser 17, and displays the parallactic image on the eyeballs 21L and 21R of an observer 20. <P>COPYRIGHT: (C)2011,JPO&INPIT |
