A three-dimensional television picture display system in which information intended for the right and left eye, respectively, of an observer is generated on a display screen (11, 20) in respective first and second images (V1, V2) which are shifted into the direction of line scan. In order to prevent eye strain due to conflicting depth information and any resultant headache, irritation and discomfort, the periodic line blanking of the second image (V2) intended for the left eye is shifted into the direction of line scan at picture generation on the display screen (11, 20) relative to the periodic line blanking of the first image (V1) intended for the right eye. The three-dimensionally shifted line blanking can be realized either electronically (6, 7; 22) or by providing on either side of the display screen (20) of the picture display device (19) strips (HB1, HB2) which transmit/do not transmit information.
A three-dimensional television picture display system comprising a picture pick-up device and a picture display device having a picture display screen and scanning means for performing, in scanning periods and with blanking periods, a periodic scanning operation of the screen at line and field frequency for generating on the screen a picture corresponding to the original scene recorded with the pick-up device, information which is intended for the right and for the left-eye, respectively, of an observer being present in this picture in first and second images, respectively, the images being shifted in the direction of line scan, which, for an entire, image information-separated observation with two eyes, results in a three-dimensional picture, characterized in that said system further comprises means for shifting the periodic line blanking of the second image relative to the periodic line blanking of the first image in the direction of line scan.
