ABSTRACT:
Method and apparatus for producing stereoscopic images for motion picture or TV using a single sensor or camera and a single lens. In carrying out the method of the invention, the camera lens is caused to rotate about an axis defined by the optical path of the incoming image rays. The apex of the cone is defined by the object being rendered. The base of the cone is defined by the image sensor portion of the camera and its circular path remains unchanged during an image rendering session. The lens of the camera, on the other hand, travels in a smaller circular path and the circumference of the path of travel of the lens is increased or decreased depending on the distance from the image to the lens and can change during the image rendering session. Apparatus comprises a frame which is driven by an electro mechanical drive mechanism for moving a camera support body through a conical path. The drive mechanism functions to drive the frame for moving a first portion of the camera support body through a circular path which remains generally constant during an image rendering session and a second portion of the camera support body through a smaller circular path which is determined by the distance from the lens to the image which is at the apex of the cone.
