ABSTRACT:
Direct eye-to-eye contact and compactness are achieved in a video display system including a camera positioned behind, or opposite the viewing side of, a display screen having first and second modes of operation. As a result, the camera and the person or persons viewing the display are on opposite sides of the display screen. The display screen is controlled to switch from the first or image display mode to the second or substantially transparent mode. When the display screen is in the substantially transparent mode, the camera is controlled to record images appearing on the viewing side of the screen.
