Camera for Desk Top Video Conferencing

       Disclosed is a low profile camera and mountings for
desk-top video conferencing, designed to maintain good eye contact
with the viewer.  Incorporated are techniques of physical packaging,
lens fine adjustment, locational and mounting arrangements suitable
for many other types of monitors, in addition to the IBM PS/2*.

      Cameras used for interactive situations with display screens
such as PS/2 monitors need to be mounted as near as possible to the
display window in order to maintain eye contact with another viewer.
Eye contact in conferencing situations has proved to be just as
important as it is in everyday conversations.  This design allows the
camera receiving lens 1 to be as close as possible to the display
screen 2 without actually obscuring it.  It also allows for a very
low profile camera 3 to be mounted on top of the monitor 4 without
appearing to be an obtrusive add-on item.  It can also be used with
standard C-Mount lenses, which are relatively inexpensive or with
sub-miniature lenses of 15 mm in diameter which cost somewhat more.

      Fig. 1 shows a plan view of the internal components required
for a complete camera.  The CCD 5 is separated from off the board 8
by the use of a flex cable 6.  This allows the CCD 5 and lens
assembly 1 to be turned through 90 degrees and sit on the monitor
bezel 7, as shown in Fig. 3.
