Abstract
An apparatus is provided for synchronizing left-and right-eye images and for providing a composite video signal for a stereoscopic television system. The synchronization operation at a field-by-field rate is assured by detecting the phase-difference between a first vertical sync pulse which is derived from the vertical sync signal which is sampled by a horizontal sync signal and a second vertical sync pulse which is constantly delayed from the vertical sync signal of the composite video signal. As a result, the left eye image is always associated with the left eye lens of the viewer and the right eye image is always associated with the right eye lens of the viewer.
