    • 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.

    • Each of left and right images of a stereoscopic television picture is divided into a plurality of blocks and a position of one of the images is shifted in such a way that a difference between one picture signal (S.sub.L) in one block of one of the left and right images and the other picture signal (S.sub.R) in a block corresponding in position to the one block is minimized, to obtain a positional shift (p,q) between one picture and the other picture. A difference signal (S3) between one picture signal (S2) shifted by the positional shift (p,q) and the other picture signal (S.sub.R) is obtained in each block. The difference signal (S3) is compressed into a data compressed difference signal (S4). The compressed difference signal (S4), one video signal (S.sub.L) and the signal (S1) representative of the positional shift (p,q) are transmitted so that an amount of signals to be transmitted can be remarkably reduced. In addition, a transmission bandwidth can be further compressed by obtaining the difference signal only with respect to an object loaded at a short distance from the television cameras and concentrated in the center portion of the picture.
