    Abstract: PURPOSE: A device for controlling vergence of a stereo camera is provided to interwork vergence control according to zoom lens operations of the stereo camera, and to perform a more exact vergence control by parallax found through a signal processing, thereby enabling a more exact vergence control in the stereo camera. CONSTITUTION: A focus controller(140) operates lens operators(121) to equalize images photographed by at least two cameras, and performs a focus control. A zoom and vergence controller(130) finds a distance between central points of the two cameras where parallax becomes zero according to positions of lenses(111) and a subject, when the focus control is performed. A camera driver(120) controls a distance between centers of the two cameras according to the distance between the central points of the two cameras, and performs a vergence control. A signal processor transmits a control signal vergence information to the camera driver according to a vergence angle, which is obtained by calculating the parallax by using video data obtained when the vergence control is performed, and carries out a 2-step vergence control.
