Abstract

Abstract PURPOSE:To remove the variation in time of pictures when video signals from two, right and left, TV cameras are double-speed converted and multiplexed by setting a time difference of 1/2 vertical period between the synchronizing signals of the cameras. CONSTITUTION:This stereoscopic video device is constituted in such a way that two sets of TV cameras 1L and 1R are provided and the synchronizing signal of one TV camera is delayed by 1/2 vertical period (Circuit 2) against the synchronizing signal (reference) of the other camera and video signals from the cameras 1L and 1R are respectively written in memories 4Lo, 4Le, 4Ro, and 4Re, and then, multiplexing signals are obtained by reading out (control circuit 5) the memories at double speed. Since the time difference of 1/2 vertical period is set between the right and left pictures at the time of photographing, no variation in time is produced in the pictures when the video signals of the pictures are double-speed converted and subjected to multiplex circuit. Therefore, unnaturalness in the movement of the pictures can be dissolved.
