A stereoscopic video viewing limiter extracts factor information related to different factors affecting a viewer of a stereoscopic video display from a video signal, generates corresponding effect coefficients representing the degree of effect on the viewer, integrates the effect coefficients as the viewer watches the stereoscopic video image, compares the integrated values with respective thresholds determined according to the viewer's tolerances for each of the factors, and generates a viewing limitation signal when the tolerances are exceeded. The viewing limitation signal is used to limit viewing to a two-dimensional video image instead of the stereoscopic video image. When several viewers watch the same stereoscopic video display, separate viewing limitation signals are generated, tailored to the viewers' individual stereoscopic viewing tolerances, permitting each viewer to enjoy the stereoscopic video display as long as possible without adverse effects.
