Camera Mount for Workstations

       Disclosed is a low-cost, unobtrusive camera mount for
workstations used in video-related applications, such as
teleconferencing and multimedia.  Its central positioning allows
viewing of documents, head-and-shoulders, together with eye contact.

      Requirements for the mounting of TV cameras in workstations
include the following:
1.   It must be unobtrusive.
2.   It must be central to the center point of the operator's natural
visual stance, i.e., the operator should appear to be looking
directly at the camera.  This is important to allow eye contact to
occur.
3.   It must allow head-and-shoulders shots of the operator at normal
viewing distances, and also provide document shots, where an A4 sheet
placed on the desk and full of ten-point Roman can be easily read.
Other sizes of document are less important and can be handled by an
optional, more expensive lens assembly.

      The technology step which has enabled these requirements to be
approached is the development of the low-diameter CCD camera.  These
devices have a diameter of about 12 to 18 mm, and lengths of less
than 100 mm. Typically, a knurled bezel 4, as shown in the figure,
screws on to the camera body 1 and, as well as carrying the basic
lens, also acts as a focussing control.  More complex lens systems
can replace bezel 4.  The bezel or more complex lens assembly, if
required, is the only thing visible and protruding from the monitor
of the workst...
