CA 2237901

An eye contact video conferencing terminal (500) comprises mirrors (521, 522), a directionally transmissive layer (601), i.e. louver assembly, and a camera (530) are positioned with respect to one another such that intimate communication is realized between the parties without substantially reducing the transmissivity of the apparatus. The louver assembly is located in front of the terminal screen and passes an image of the distant party radiated from the terminal screen which is subtantially parallel to the louver assembly. A first partially silvered mirror (521), reflects the image of the local party and transmits the image of the distant party that is radiated from the terminal screen (125) and passed by the lower assembly. The reflected image of the local party is directed toward a second mirror (522) located below the first mirror, and is positioned to capture the image of the local party from the first mirror and to reflect this image into a miniature camera.

Un terminal à contact visuel pour vidéoconférence (500) comporte des miroirs (521, 522), une couche à transmission directionnelle (601), un ensemble à claire-voie par exemple, et un appareil de prise de vues (530), disposés l'un par rapport à l'autre de façon à pouvoir instaurer une communication en toute intimité entre les interlocuteurs sans réduire de manière sensible la transmittivité de l'appareil. L'ensemble à claire-voie, qui se trouve sur le devant d'un écran de terminal, transmet une image de l'interlocuteur éloigné, image émise par l'écran du terminal se trouvant sensiblement parallèle à l'ensemble à claire-voie. Un premier miroir (521), partiellement étamé, réfléchit l'image de l'interlocuteur local et transmet l'image de l'interlocuteur éloigné, émise par l'écran du terminal (125) et ayant traversé l'ensemble à claire-voie. L'image réfléchie de l'interlocuteur local est dirigée vers un second miroir (522) situé sous le premier et placé de manière à saisir cette image provenant du premier miroir et à la réfléchir dans un appareil de prise de vues miniature.
