ABSTRACT:
A video conferencing system includes a camera and a display within a room. The camera is directed towards participants in a foreground against a background. The room has lighting defining at least foreground luminance. The display defines maximum display luminance, and the display and flare of the room define minimum display luminance. The camera, the display, and/or the room are adapted to provide one or more of the following. First, that the maximum display luminance is greater than the foreground luminance but less than the foreground luminance times a first constant. Second, that the maximum display luminance is greater than the minimum display luminance by more than a second constant. Third, that illumination color of foreground images displayed on the display substantially match illumination color of the foreground. Fourth, that a color of background images displayed on the display substantially matches a color of the background.
