Abstract
When a 2-dimensional video image is displayed, a front/rear feeling and a stereoscopic feeling are enabled to be expressed. A detection signal Sd is formed by a high pass filter,and a rectifying circuit,in accordance with an amount of edge information. The detection signal Sd is supplied to a variable delay circuit,L. A detection signal Sd′ is supplied to a variable delay circuit,R. The variable delay circuits,L and,R are controlled in accordance with the edge information amount so that a video image for the left eye and a video image for the right eye are moved in the opposite directions. Thus, an imaginary image is synthesized to the front or rear side from a display plane. The left and right video images are displayed on CRTs,L and,R. The projection light passes through a horizontal polarizing filter,L and a vertical polarizing filter,R and the left and right video images are overlapped on a screen,. The left and right video images are separately observed by glasses,having polarizing filters,L and,R and a stereoscopic feeling is enhanced.
