Abstract
There is disclosed stereographic camera system including a left and a right camera including respective lenses, plural mechanisms to synchronously set a focal length of the lenses, to synchronously set a focal distance of the lenses, to set a convergence angle between the left and right cameras, and to set an intraocular distance between the left and right cameras. A distance measuring device may be used to measure the distance to an extreme object. A controller may cause an interocular distance and a convergence angle between the left and right cameras to be set based on a maximum allowable disparity, the focal length of the lenses, and a convergence distance.
