Abstract
A method and apparatus for widening a viewing angle in a video conferencing system are provided. The apparatus for widening a viewing angle in a video conferencing system includes: generating reference data from images of a video conference participant captured by a camera included in the video conferencing system; generating movement data based on the video conference participant's movements sensed by the camera; extracting a first control parameter by comparing the reference data with the movement data; transmitting the first control parameter to the other end of the conference; receiving a second control parameter generated at the other end of the conference; and controlling the camera by the second control parameter.
Claims8
A method for widening a viewing angle in a video conferencing system, the method comprising:
- generating reference data from images of a video conference participant captured by a camera included in the video conferencing system;
- generating movement data based on the video conference participant's movements sensed by the camera;
- extracting a first control parameter by comparing the reference data with the movement data;
- transmitting the first control parameter to the other end of the conference;
- receiving a second control parameter generated at the other end of the conference;
- and
- controlling the camera by the second control parameter.
An apparatus for widening a viewing angle in a video conferencing system, the apparatus comprising:
- a camera controller that generates reference data from images of a video conference participant captured by a camera included in the video conferencing system, generates movement data based on the video conference participant's movements sensed by the camera, and controls the camera by a first control parameter generated at the other end of the conference;
- a parameter extractor that extracts the first control parameter by comparing the reference data with the movement data;
- and
- a signal processor that transmits the first control parameter to the other end of the conference and receives a second control parameter generated at the other end of the conference.
