Abstract
Generally, the present invention relates to a video teleconference system which is amenable to the mobile and stationery/desktop environment with concurrent parallax correction and background suppression for privacy. An embodiment of the invention is directed to a video teleconference system for allowing a first conferee to maintain direct eye contact with a second conferee, the system including an image display emanating a linearly polarized image output of the second conferee. A partially reflecting, partially transparent beam splitter is interposed between the first conferee and the image display, the beam splitter disposed at an angle relative to the line of sight of the first conferee and the image display, the splitter being hingeably attached to display. A video camera is oriented to receive the reflected image of the first conferee as projected off the beam splitter. An optical (linear) polarizer is oriented orthogonally to the polarized light from the display disposed between the beam splitter and the video camera thereby minimizing eye contact parallax between the first and second conferees.
