Problems solved by technology

But users rarely, if ever, change their head position and line of sight to focus on the camera instead of the display, and even when they do, the user's head position adjustments are unnatural and require different less concentration and effort
This prior art system is problematic due to the inability to capture a direct full-face image of the user
In short, there is never a time when two users look directly at each other, see a full face image on the screen, and make eye contact

Abstract

The invention discloses a device and method for an end point of a video conference. The device and method provide visual contact between participants in different conference sites. The invention allows placing a conference camera in the beam of a projector device without degrading the quality of the view captured by the camera due to the light from the projector. This is achieved by creating a dark spot in the light beam, covering the camera lens, and adjusting the position and / or size of the dark spot based on a camera position detector, which can be the camera itself or near the camera lens or Multiple light sensors around.

Description

field of invention [0001] This invention relates to video conferencing systems, and more particularly, to video capture and display systems that provide line-of-sight contact between video conference participants. Background of the invention [0002] Face-to-face conversations are often considered the best form of human communication. Therefore, the purpose of the video conferencing system is to achieve as close to real face-to-face conversation as possible. [0003] A typical video conferencing system includes display screens and cameras for each venue. During the video conference, users in the first conference site watch images of the second conference site on the display screen. At the same time, the image of the first meeting place is captured by the camera and projected onto the display screen of the second meeting place. The users of the second conference site watch the image of the first conference site on the second display screen, and the camera of the second con...
