ABSTRACT:
A stereoscopic television apparatus comprises two image sensors which alternately output image signals respectively corresponding to those of the right and left eyes, a monitor alternately displaying the image signals of the two image sensors as first and second field images, and a shutter member having right and left shutters alternately switched in synchronism with the alternating displays of the first and second field images, to create a stereoscopic image. A marker generator inputs brightness signals corresponding to markers into the monitor, to provide the markers at two arbitrary poionts in the stereoscopic image. A distance calculator calculates the distance between the markers, based on the coordinates X, Y, Z obtained by processing the marker signals.
