Abstract
A method and apparatus for electronically taking photographs of an object to be used for stereoscopic (three dimensional) reproductions of the object in which an electronic camera takes a plurality of electronic photographs of an object from each of a plurality of predetermined spaced positions relative to the object. The photographic image is converted into a video signal which is digitized and the digitized video signals of the images from the plurality of positions are utilized to produce a viewable representation of the object. In a preferred embodiment, the camera has a generally planar element for converting the image into the video signal and the planar converting element of the camera at each position is held in a common plane and the lens system for the camera at each position is kept in a plane generally parallel to the converting element plane and shifted relative to the image converting element of the camera to compensate for the different positions to have the same field of view at each position.
