Abstract
In synchronism with a vertical synchronizing signal of a display for temporarily alternatively displaying a right eye picture and a left eye picture cooperative with each other to provide binocular parallax information, a shifter is controlled to shift a first parallax barrier by half a pitch of stripe regions thereof to effect a switching between a state in which every other stripe region is transparent and the remaining stripe regions are all shading and a reversed state thereof so that the right eye picture and the left eye picture are independently observable by a right eye and a left eye of an observer, respectively, through the first parallax barrier and a second parallax barrier composed of a plurality of stripe regions of which every other one is transparent while the remaining ones are all shading.
