PURPOSE:To obtain the eye contact to the other party by image picking-up and transmitting pictures R and L while plane image pickup elements scan parts other than the aperture of a lens in a plane display device. CONSTITUTION:The plane display device 21 alternately displays the received pictures R and L, and a polarizer 22 passes through only light polarized in the a fixed direction among light outputted from the plane display device 21. In synchronization with switching a display screen, a liquid crystal cell 23 outputs the light polarized in the direction as it is or by rotating it by 90 deg.. Consequently the pictures R and L are alternately displayed through lights in different polarization directions. A caller uses polarization glasses which have a polarization lens corresponding to the picture R and a polarization lens corresponding to the picture L. The plane image pickup elements 261 and 262 stop scanning while the plane display device 21 is scanning in the apertures of lenses 251 and 252. While the device 21 is scanning other parts except for the apertures, the elements 261 and 262 operate, decompose the image of the caller which is formed through the lenses 251 and 252 to the pictures R and L, pick up images and transmit them. |
