Abstract:
1. An arrangement of a videoconference end-point comprising: a projective surface; a video projector emitting a beam of light creating one or more images on the projective surface; an end-point associated video camera directed towards the video projector and residing within said beam of light; a beam area generator adapted to generate an area of light or absence of light in said beam replacing a part of, and/or adding a part to, said one or more images, to cover at least a part of said video camera and thereby prevent the video camera from substantially capturing the beam of light; and a camera position detector adapted for determining size and shape of said area, wherein the camera position detector is adapted to detect position, orientation and/or tilt and/or changes in position, orientation and/or tilt of the video camera relative to said one or more images and to provide information of the position and changes to said beam area generator for placing and adjusting said area of light or absence of light to cover at least a part of said camera.
