Abstract: A videoconferencing unit comprises a display screen configured to display a video data stream comprising images of a far end participant. A processor is adapted to decode the video data stream and generate a modified region of the video data stream. The modified region of the video data stream is displayed on the display screen at a location where images of eyes of the far end participant are displayed on the display screen. A camera is configured with a lens to capture images of a near end participant through the modified region of the video data stream, with at least a portion of the lens positioned within the modified region of the video data stream.

Abstract: A videoconferencing unit for enhancing direct eye-contact between participants can include a curved fully reflective mirror to reflect the image of the near end to a camera. The curved mirror can be placed in front of the display screen near a location where images of faces/eyes of far end participants are to appear. In another example, the videoconferencing unit can include a disintegrated camera configuration that provides an air gap between a front lens element and a rear lens element. The front lens element can be located behind an aperture within the display screen. The air gap can provide an unobstructed path to light from projectors and therefore avoid any undesirable shadows from appearing on the display screen. In another example, the videoconferencing unit can include a combination of the disintegrated camera configuration and mirrors for providing direct eye contact videoconferencing.

Abstract translation: 用于增强参与者之间的直接眼睛接触的视频会议单元可以包括用于将近端的图像反射到相机的弯曲的全反射镜。 曲面镜可以放置在显示屏前方，靠近要出现远端参与者的脸部/眼睛的图像的位置。 在另一示例中，视频会议单元可以包括在前透镜元件和后透镜元件之间提供气隙的分解照相机配置。 前透镜元件可以位于显示屏内的孔的后面。 空气间隙可以为投影机的光提供无阻碍的路径，因此避免了不希望的阴影出现在显示屏上。 在另一示例中，视频会议单元可以包括分解的相机配置和镜子的组合，用于提供直接的眼睛接触视频会议。
