PURPOSE:To make it unnecessary for a user to put on a unit such as polarizing spectacles, etc., by employing a device which principally perform rotation control over a polygon mirror, etc., varying the length of the optical path reaching the eye of the observer and forming an image which has depth-directional extent. CONSTITUTION:Rotation controllers 91 and 92 control both polygon mirrors 81 and 82 so as to set the optical path length short when an image read out of a video processing and recording device 5 has 'close' depth information or long when 'far' information, and a lens controller 12 controls a lens 11 to propagate the display image in the formed optical path. The image formed on a video display device 7 from the video processing and recording device 5 by a video reader 6 increases or decreases in the distance to the observer with the depth information. The display process of the image is completed within a time of continuation of the after image phenomenon of the human sense of sight, so the observer effectively observes the image with the depth- directional extent, i.e., feels a stereoscopic image. |
