STEREOSCOPIC TELEVISION DEVICE TOTALLY BIDIMENSIONALLY COMPATIBLE, WITHOUT ALTERATION OF THE COLOURS, APPLICABLE TO S.E.C.A.M STANDARDS

摘要

A first camera (a) supplies bidimensionally the broadcast according to S.E.C.A.M standards (m). The crominance subcarrier, modulated in frequency is also modulated in amplitude by the red signal of a second synchronized camera (b) providing for the left vision of the stereoscopic couple. A circuit adaptable to a colour receiver allows the normal bidimensional or stereoscopic reception (n). An original filter device restores the relief vision without alteration of the colours (p). The latter device is applicable to movies, projections of slides and relief printings.
