Abstract
A stereo image forming apparatus for observing a stereo image based on two images obtained by two image taking systems. In front of each image taking system, such as a television camera, two wedge-shaped prisms are placed and made rotatable in mutually opposite directions, thus deflecting the direction of light for a varying distance to the object, in synchronization with the focusing operation of the image taking system. Thus, the apparatus can promptly focus on the object at varying distances without rotating the image taking systems themselves.
