Abstract
A video conference system includes a camera, camera driving section, human figure extracting section, human figure picture storage section, camera parameter storage section, and human figure instructing section. The imaging direction and field angle of the view of the camera can be changed. The camera driving section controls the imaging direction and field angle of the camera view in accordance with camera parameters. The human figure extracting section extracts a human figure picture of each participant from a picture obtained by capturing an entire conference room, and calculates camera parameters associated with the imaging direction and field angle of the camera view on the basis of the extracted human figure picture. The human figure picture storage section stores the extracted human figure picture. The camera parameter storage section stores the camera parameters calculated by the human figure extracting section. The human figure instructing section reads out camera parameters corresponding to a human figure picture selected as a shooting target from the human figure pictures stored in the human figure picture storage section from the camera parameter storage section, and outputs the camera parameters to the camera driving section.
