APPARATUS FOR ENABLING STEREOSCOPIC VIEWING

摘要

Apparatus (8) for enabling stereoscopic viewing, which apparatus (8) comprises a first screen (10) for being viewed by a first eye of a person, and a second screen (12) for being viewed by a second eye of the person, and the apparatus (8) being such that each screen is rotated 900 clockwise from a position required if the apparatus (8) were to be driven by a video input signal giving non-stereoscopic viewing, each screen has during use a first image (6) for the first eye and a second image (7) for the second eye, a first mask (14) for the first screen (10) masks one of the first (6). and second images (7) on the first screen (10), a second mask (16) for the second screen (12) masks one of the first (6) and second images (7) on the second screen, and the first and second screens (10, 12) are displaced with respect to each other such that the displacement and the masks ensure that there is only one image (6) or (7) on each screen that is viewable by each eye, and the image (6) that is viewable on the first screen (10) is on an axis for the first eye, and the image (7) that is viewable on the second screen (12) is on an axis for the second eye, whereby the apparatus (8) is able to be driven by a video input signal giving the stereoscopic viewing.
