Abstract:
1. A three-dimensional observation apparatus comprising: a pair of image projection means; an image display means; a position detecting means for detecting movements of an observer of images displayed by the image display means; and driving means for tracking movements of the observer and for moving the image display means based on changes of signals that are output from the position detecting means; wherein the pair of image projection means and the image display means are configured such that the pair of image projection means projects a right eye image, and a left eye image, and the image display means presents these images to the right eye and left eye, respectively, of an observer; the pair of image projection means, the image display means, and the position detecting means are mounted on a first supporting body; the first supporting body is mounted to a second supporting body that supports the first supporting body via the driving means; and the driving means is configured so as to be capable of moving the pair of image projection means, the image display means, and the position detecting means via the first supporting body as a whole relative to the second supporting body.
