Abstract
A camera mounted on a computer system such as on a side of a monitor or behind a displayed image to reduce the parallax that results from a camera viewing angle that differs from a viewed party's viewing angle of a display, and that causes unnatural looking video communications. An item of interest corresponding to a focal point of the user that is being viewed, such as a counterpart displayed video image from a participant in the communication, may be positioned near the camera, such that the user tends to look in the general direction of the camera while communicating. Camera movement may be sensed to facilitate automatic or manual repositioning of the displayed item of interest, and a participant, such as a remote participant receiving video in a video communication may control the position of a displayed image on the monitor to minimize the parallax.
