Stereographic image capturing apparatus having interocular distance controller and method for controlling depth perception of stereographic image using the same

An apparatus for capturing a stereographic image, comprising:

• a left-eye camera and a right-eye camera;
• a camera rig on which the left-eye camera and the right-eye camera are installed;
• and
• a camera rig control module configured to control movement of the camera rig and thus control the left-eye camera and the right-eye camera installed on the camera rig,
• wherein the camera rig control module comprises:
• an interocular-distance-DB storage unit creating and storing an interocular distance DB (database), the interocular distance DB including information both about an interocular distance between the left-eye camera and the right-eye camera at a reference distance, which is an initial image capturing distance between the camera rig and a target, and about an interocular distance to be changed when the image capturing distance is changed by zooming in or out from the reference distance;
• a changed-distance calculator using, when the left-eye camera and the right-eye camera are zoomed in or out at the reference distance, a change value of lens data changed by the zooming in or out and thus calculating an image capturing distance changed by zooming in or out on the target;
• and
• an interocular distance controller finding, from the interocular distance DB, a new interocular distance value corresponding to the image capturing distance changed by the zooming in or out, the interocular distance controller adjusting, using motors installed in the camera rig control module, the interocular distance between the cameras to the new interocular distance value found from the interocular distance DB.
