Abstract: Parallax images corresponding to a plurality of different view points are each divided into predetermined stripe images, a synthetic parallax image is synthesized from the stripe images, and display light, from stripe images corresponding to one view point of the synthetic parallax image on the image display element displaying the synthetic parallax image, is guided to a mask member having a mask pattern with predetermined openings and shields by a second optical system placed in front of the image display element. The display light passing through the openings of the mask member is condensed to a position corresponding to the view point on an observation surface a predetermined distance apart, by a first optical system, whereby an observer is permitted to stereoscopically observe image information displayed on the image display element.

Abstract: It is an object of the present invention to provide a stereoscopic image displaying method and a stereoscopic image displaying apparatus using the same, which are capable of excellently observing a stereoscopic image.

Abstract: This invention has as its object to provide a viewpoint detection apparatus and method, which can assure high-speed processing, high precision, and high tracking performance with a simple arrangement while suppressing adverse influences on the human body, and a stereoscopic image display apparatus using the same. The viewpoint position detection apparatus of this invention has an image sensing unit (1) and a viewpoint detection unit (2). The image sensing unit has a visible image sensing section (11) and infrared image sensing section (12). A pupil position detection processing section (24) detects the pupil position from an infrared image, and a template generation section (23) generates templates for a visible image using the pupil position obtained from the infrared image. A pattern matching discrimination section (22) executes pattern matching of a visible image.

Abstract: A stereoscopic image display apparatus has a display section 110 and a visual point position detecting mechanism for detecting positional information of an observer. The display apparatus uses an optical barrier having a mask pattern formed therein, and makes a patterned beam pass through an optical system to illuminate a display having a discrete pixel structure and displaying a synthetic parallax image by use of scanning lines. The observer stereoscopically observes the image information displayed on the display. The synthetic parallax image is comprised of m parallax images where m is an integer not less than 3. The contents of the synthetic parallax image are changed according to visual point position information outputted from the visual point position detecting mechanism according to positions of visual points of the observer.
