Abstract
Stereoscopic video system and method in which left and right images are displayed during alternate fields of a video picture frame. The equalization pulses occurring during the vertical blanking interval at the outset of each field are counted to identify the field. The field identification information is utilized to synchronize the presentation of the images to the proper eyes of a viewer. Flickering of the images seen by the viewer is reduced by limiting the intensity or brightness of the displayed images to which the eyes of the viewer are exposed.
