1. A stereographic camera system, comprising: a left camera and a right camera including respective lenses having a focal length and a focus distance; an interocular distance mechanism to set an intraocular distance between the left and right cameras; and a controller configured to receive inputs indicating the focal length and the focus distance of the lenses, and control the intraocular distance mechanism, based on the focal length and focus distance of the lenses and one or both of a distance to a nearest foreground object and a distance to a furthest background object, to automatically set the interocular distance such that a maximum disparity of a stereographic image captured by the left and right cameras does not exceed a predetermined maximum disparity.
