PCT No. PCT/JP86/00232 Sec. 371 Date Dec. 31, 1986 Sec. 102(e) Date Dec. 31, 1986 PCT Filed May 6, 1986 PCT Pub. No. WO86/06914 PCT Pub. Date Nov. 20, 1986.A stereoscopic television picture transmission system includes a device (14) for obtaining a picture signal with respect to one of right and left pictures in a stereoscopic television, circuitry (22) for obtaining a difference signal between a right picture signal for the right picture and a left picture signal for the left picture, circuitry (27, 28, 29, 30) for effecting sub-Nyquist sampling of the difference signal at a frame period relating to a critical frequency for stereoscopic visual perception in a direction of depth to obtain a sampled difference signal, circuitry (36, 42) for combining one picture signal with the sampled difference signal to form a combined signal and for transmitting the combined signal, circuitry (50) for separating one picture signal and the difference signal from the transmitted combined signal, circuitry (56, 58, 60) for judging a motion between frames of the separated one picture signal, circuitry (62, 64) responsive to the motion judgement result for effecting interframe interpolation of the separated difference signal, and circuitry (66) for combining the separated one picture signal with the interframe interpolated difference signal to obtain the other picture signal of the right and left picture signals. When a frequency band occupied by a motion picture is compressed in accordance with the invention, the high frequency component of the difference signal, which would be difficult to transmit were the difference signal merely compressed, can be transmitted within the frequency band for a conventional one channel television signal.
