Stereoscopic color television

Claim 3

A method of stereoscopic colour television according to claim 1, in which the colour signal carrying limited information on the magenta, red and blue colours of the composite signal obtained due to matrixing of the signals of the colour-separated images carrying information on the green, red and blue components (G 1 , R 1 , B 1 ) of the first frame of the stereo pair consists of a separate signal carrying information on the magenta, a separate signal carrying information on the red colour and a separate signal carrying information on the blue colour, while the colour signal carrying limited information on the magenta and red colour of the first signal obtained due to matrixing the signals of colour-separated images carrying information on the green, red and blue components (G 2 , R 2 , B 2 ) of the second frame of the stereo pair consists of a separate signal carrying information on the magenta and a separate signal carrying information on the red colour, while the colour signal carrying limited information on the magenta and blue colour of the second signal obtained due to matrixing the signals of colour-separated images carrying information on the green, red and blue components (G 2 , R 2 , B 2 ) of the second frame of the stereo pair consists of a separate signal carrying information on the magenta and a separate signal carrying information on the blue colour.

Claim 6

A method of stereoscopic colour television according to claim 3, including the steps of conversion, by means of matrixing, of said signals of the colour-separated images carrying information on the green, red and blue components (G 1 , R 1 , B 1 ) of the first frame of the stereo pair having a form: G.sub.1 +b.sub.1 R.sub.k.sbsb.1 +c.sub.1 B.sub.k.sbsb.1 +a.sub.2 G.sub.k.sbsb.1 +M.sub.1, where G 1 is the signal carrying information on the green component and having an upper frequency range limit accepted for colour reproduction; G k .sbsb.1 =R 1 -G 1 ≧0 is the separate colour carrying limited information on the magenta and red colour and serving as a colour difference signal whose polarity is limited by the domain of positive values and whose frequency is limited by the same upper range as G 1 ; B k .sbsb.1 =B 1 -G 1 ≧0 is the separate colour signal carrying limited information on the magenta and blue colour and serving as a colour difference signal whose polarity is limited by the domain of positive values and whose frequency is limited by the same upper range as G 1 ; G k .sbsb.1 =G 1 -R 1 -B 1 '≧0 is the colour signal carrying limited information on the green colour and serving as a three-component colour difference signal whose polarity is limited by the domain of positive values and whose frequency is limited by the same upper range as G 1 , where -B 1 '=R 1 -B 1 ≧0 is the colour-difference signal whose polarity is limited by the domain of negative values; M 1 =0.6 G+0.3 R 1 +0.1 B 1 are high-frequency components of the primary signals of the first frame; conversion, by means of matrixing, of said signals of the colour-separated images carrying information on the green, red and blue components (G 2 , R 2 , B 2 ) of the second frame of the stereo pair into two signals having a form: R.sub.2 +a.sub.1 G.sub.k.sbsb.2 +b.sub.2 R.sub.k.sbsb.2 and B.sub.2 +a.sub.1 G.sub.k.sub.2 +c.sub.2 B.sub.k.sbsb.2, where R 2 is the signal carrying information on the red component; B 2 is the signal carrying information on the blue component; G k .sbsb.2 =G 2 -B 2 -R 2 '≧0 the colour signal carrying limited information on the green colour and serving as a three-component colour-difference signal whose polarity is limited by the domain of positive values, where -R 2 '==B 2 -R 2 ≧0 is the colour-difference signal whose polarity is limited by the domain of negative values; R k .sbsb.2 =R 2 -G 2 ≧0 is the colour signal carrying limited information on the magenta and red colour, said signal being a colour difference signal whose polarity is limited by the domain of positive values; B k .sbsb.2 =B 2 -G 2 ≧0 is the selective colour signal carrying limited information on the magenta and blue colour; in this case the coefficients a 1 , b 1 , c 1 are selected so as to provide stereoscopicity and eliminate colour distortions with green, magenta, red and blue saturated colours, while the coefficients a 2 , b 2 , c 2 are selected so as to compensate the drop in the saturation of the green, magenta, red and blue colour tones.
