Abstract: A display apparatus for displaying a three-dimensional image includes an image display section for displaying an image in response to an input image signal and for displaying a three-dimensional image in response to an input three-dimensional image signal when a three-dimensional image display mode is set, and a barrier display section having a barrier display liquid crystal panel of the transmitting type, for displaying a parallax barrier onto the barrier display liquid crystal panel so that a part of the three-dimensional image which is displayed by image display means can be observed from a gap of the parallax barrier in the three-dimensional image display mode.

Abstract: Two recording tracks (T1) and (T2) are formed in parallel with each other on a stereoscopic video disc record (D). Image information for a right eye and audio information are serially recorded on one recording track (T1). Image information for a left eye and audio information are serially recorded on the recording track (T2) at a synchronized timing with the image information for a right eye and the audio information recorded on the adjacent recording track T1. Information can be easily recorded on such steroscopic video disc record (D) in a manner that the image information for right and left eyes and the audio information are recorded at the same time by two recording beams. On the other hand, stereoscopic image information can be reproduced by reproducing respective recording tracks at the same time by two reproducing means. Furthermore, a normal two dimensional image information can be reproduced by reproducing either one of the recording tracks serially by one reproducing beam.

Abstract: 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 int

Abstract: 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.

Abstract: The picture signal to be displayed on the viewfinder is corrected so as to be adaptive to the spatial frequency performance of visual system at close viewing distance of about three times of the viewing screen height. As a result, the luminance or the coloring of edge portions of the viewed picture is clearly emphasized and hence accurate and rapid focusing of pickup lens provided in any kind of TV camera is facilitated without conventional trial and error.
