A stereoscopic color television system in which operation of a plurality of color television cameras photographing the same object is switched over in turn per period of a color synchronization subcarrier to send forth video outputs from the plural color television cameras in succession. A stereoscopic color television picture tube includes a lenticular lens assembly whose lenticular lenses are each formed with an equal width to the horizontal pitch of apertures of a shadow mask or meshy focusing grid, and which is positioned between the shadow mask and face plate and also provided with a phosphor screen on the focal plane of the lenticular lens assembly, the phosphor screen being formed of a plurality of sets of red, green and blue phosphor stripes formed with an equal width to the vertical pitch of apertures of the shadow mask or meshy focusing grid. The color television picture tube further includes vertically arranged red, green and blue electron guns. The electron guns are provided in the same number of groups as the television cameras used, and operation of the groups of the electron guns is changed over successively, each time the operation of the color television cameras is switched over. Or, the color television picture tube includes one set of vertically arranged electron guns and electrostatic deflection electrodes or an electromagnetic deflection device arranged so as to horizontally shift electron beams from the set of electron guns, each time the operation of the plural color television cameras is changed over. |
