1. A method of automatically converging a plurality of images for use in a stereoscopic camera system including a plurality of 2-D cameras, the method comprising: receiving a focal distance from each of the plurality of 2-D cameras; calculating a system focal distance of the stereoscopic camera system by using the focal distances received from the plurality of 2-D cameras; determining a center of interest using the calculated system focal distance of the stereoscopic camera system; receiving the plurality of images from the plurality of 2-D cameras, wherein each of the plurality of images is generated by each of the plurality of 2-D cameras using the focal distance; and cropping the plurality of images to adjust directions of view of the plurality of 2-D cameras to converge at the center of interest.
