Abstract
A stereographic camera system and a method of operating a stereographic camera system. The stereoscopic camera system may include a left camera and a right camera having respective left and right lenses, a zoom mechanism to set a focal length of the left and right lenses, a focus mechanism to set a focus distance of the left and right lenses, and an IOD mechanism to set an interocular distance between the left and right cameras. A foreground distance sensor may sense, in near-real time, a distance to a closest foreground object. A controller may cause the IOD mechanism to set the interocular distance based on, in part, the focal length, the focus distance, and the distance to the closest foreground object.
