Stereoscopic image display apparatus for detecting viewpoint and forming stereoscopic image while following up viewpoint position
First Claim
1. A stereoscopic image display apparatus which allows an observer to observe a stereoscopic image by guiding light beams based on a plurality of parallax images displayed on an image display unit to the observer through an optical system, comprising:
- a viewpoint position detection sensor for detecting the viewpoint position of the observer; and
follow-up control means for performing follow-up control on a stereoscopic view observation region for image information displayed on said image display unit, on the basis of viewpoint position information obtained by said viewpoint position detection sensor, said viewpoint position detection sensor including light-emitting means for emitting a light beam to the observer, narrow-area detection means for detecting a viewpoint position in a narrow area, and wide-area detection means for detecting a viewpoint position in a wide area.

Abstract
A system and method is disclosed for forming stereoscopic images. The images are formed through the arrangement of a viewpoint position detection sensor for emitting visible or infrared light to an observer. Reflected light is then detected from the observer, where controls perform follow-up control on a portion of the apparatus by using the signal obtained by the viewpoint position detection sensor. The signal, along with other desired signals, are then properly set to accurately detect the viewpoint position of the observer with a simplified arrangement that easily allows a stereoscopic view region to follow-up at high speeds.
