ABSTRACT:
A video teleconferencing network among several remote sites includes a central switching system for receiving and processing signals from the remote sites. Video cameras are located at each one of the remote sites for generating video signals. Each camera includes an optical system having a plurality of lens systems for processing colors of different frequencies. Each one of the lens systems includes a shutter for generating amplitude vectorial signals proportional to the amplitude of the color signal being processed by the lens system. Each one of the lens systems further includes means responsive to the frequency of the corresponding color being processed by the particular lens system, for generating vectorial signals proportional to the frequency of the color signal being processed by the lens system. A modular monitor has a relatively small size liquid crystal modular screen, for use by an individual user to display texts and graphics. The modular screen includes a plurality of modules selectively engageable to one another, by the individual user, to form a single unitary screen. A user station is adapted to be coupled to the single unitary screen, for controlling the display of information thereon.
