ABSTRACT:
An image viewing system to permit viewing of three-dimensional images, wherein users wear a pair of eyeglasses to view displayed images. The pair of eyeglasses include lenses having LCD polarizing filters and a LCD controlling unit configured to adjust the polarization of the lenses based upon the orientation of the glasses. A sensing unit, located on the glasses, monitors the orientation of the glasses and when the orientation is skewed from a default orientation, the sensing unit notifies the controlling unit of the new orientation. Upon receipt of the new orientation, the controlling unit then initiates a change in the polarization of the LCD filters. Adjustment of the polarization allows users of 3-D viewing glasses to freely adjust head position relative to the displayed images without compromising the integrity of the viewed image.
