ABSTRACT:
In a stereoscopic television display device, the timing of read out data of a frame memory for right eye and the timing of read out data of a frame memory for left eye are shifted with respect to each other other so that the observer can freely select a point other than a camera's observation point as his observation point. Furthermore, according to another aspect of the invention, a stereoscopic television image pickup device is provided in which an electrically controllable aperture and an optical transmission plate having an electrically controllable transmittance are disposed between an object and image pickup units for right eye bad left eye, and in each image pickup unit the aperture and the transmittance are controlled so that the video signal level and the degree of opening of the aperture are set to desired values.
