发明名称 EYE CONTACT VIDEO-CONFERENCING SYSTEM AND SCREEN
摘要 Our video-conferencing system (10) comprises stations (20, 30) which are remotely located from one another and interconnected by a transmission system (12). Each station includes a camera (23, 33), a projector (21, 31), and a screen (22, 32), which is simultaneously translucent with respect to the projector and transparent with respect to the camera. The projector as well as the camera are placed behind and in line with the screen, thus allowing greater viewing reciprocity and eye-contact and projecting a stronger feeling of reality to the video-conferencing parties. Our screen includes segments which discriminates between projected light and light to be captured by the camera based upon polarization or angle.
