Stereoscopic display apparatus for generating images in accordance with an observer's viewing position

摘要

A stereoscopic display apparatus such that when an viewing point position of an observer is moved, a stereoscopic image similar to that observed at the moved position is obtained. A plurality of images according to a plurality of viewing point positions are generated from right/left image generating apparatuses. One of the plurality of images selected by a switching device is supplied to an image display apparatus. An observer observes a stereoscopic image by a liquid crystal driving apparatus, liquid crystal polarizing plates, and polarizing spectacles. Infrared rays from infrared light emitting devices are partially obstructed by the observer and are received by infrared photosensitive devices. A position detection processing circuit judges the image according to an viewing point position of the observer from detection signals, thereby switching the switching device to the right/left image generating apparatuses.
