摘要： PROBLEM TO BE SOLVED: To shorten the communication time and to reduce the traffic jam by displaying an image, causing the stereoscopic feeling and an image causing no stereoscopic feeling on the same screen. SOLUTION: At least one of the objects is selected with operation of a pointer which is provided on a display screen and controlled by a pointing means. Then a processor 11 controls a communication means 13 to access a data storage device 18, placed at a remote point via a communication circuit. Thus, the stereoscopic information on the selected object is inputted to an image- display device. The acquired data are stored in a data storage means 17, sent to an image-display part 14 via an image processing means 16 and converted into an image. Then the image is made incident on the right and left eyes of an observer by an optical means 15. As a result, a stereoscopic image can be displayed at only a part of a display area.

摘要： PROBLEM TO BE SOLVED: To enable an observer to view normal stereoscopic images in any postures by detecting the positions of both eyes of the observer and rotationally controlling barrier gratings in such a manner that the barrier gratings are held always perpendicular to a line connecting both eyes. SOLUTION: A display device 100 is composed of a display section 140, a parallax barrier section 130 and an image processing section. The barrier section 130 is made rotationally controllable by a dynamic mechanism and the method for controlling the rotation thereof is executed by subjecting the visual line direction vector of the observer 150 to image processing computation by an IR generator 110 disposed in the upper part of the display device 100 and an IR, camera 120. The direction of the parallax barrier is rotationally controlled in such a manner that this direction is held always perpendicular to the segment direction (visual line direction vector) of both eyes of the observer 150 at this point. The stripe direction of the displayed image and the parallax direction of both eyes are controlled in compliance therewith, by which the observer is enable to observe always the normal stereoscopic images in any postures.
