Embodiment Construction

[0044] FIG. 1 shows an apparatus 1 allowing videoconferencing communication between a local user 5 and a remote user 6 . In a variant embodiment, said conference video communication can take place between a local user 5 and several remote users.

[0045] Said device 1 comprises a screen 4 capable of reproducing for a local user 5 the image of a remote user 6 . It also includes an image sensor 3 capable of capturing images of the local user 5 for viewing by the remote user 6 .

[0046] The image sensor 3 may be, for example, a video camera or camera head. Thus, the term "camera" will denote the image sensor in the following description, and this denotation does not form any limitation. For example, the camera may consist of a webcam.

[0047] Furthermore, in order to reduce the "two-sided" effect, the device 1 comprises a light source 2 arranged to illuminate the eyes of the local user 5 while the local user 5 is looking at the screen 4 in communication with the remote user 6 ...

Abstract

The device (1) has a screen (4) e.g. TV set screen, for restoring an image of a remote user (6) to a local user (5), and an image sensor e.g. camera (3), for capturing an image of the local user to an attention of the remote user. A light source (2) illuminates eyes of the local user viewing the screen during communication with the remote user, such that the image sensor captures the local user's image with a reflection of the light source on each eye of the local user, including a pupil. An independent claim is also included for a method for videoconference between a local user and a remote user.

Description

technical field [0001] The present invention relates to videoconferencing communications. Background technique [0002] A video conference allows at least two users to communicate with each other not only by voice but also by vision. Virtually every user can obtain images of the other user(s) participating in the communication. [0003] To this end, each user has a screen capable of reproducing the images of the other user(s) participating in the communication, and an image sensor approximately close to the screen that captures the user's own image for viewing by the other user(s). [0004] One problem with videoconferencing is the fact that users see images of other user(s) on their screens, not on an image sensor. The resulting impression is that different users are not making eye contact. This effect is sometimes referred to as the "two-faced" effect. This effect prevents high-quality communication between participants. [0005] Several solutions have been proposed t...
