ABSTRACT:
A stereoscopic camera for taking a stereoscopic picture of a three dimensional object on a photographic film carrying a lenticular film. The camera has a positive objective having a focal length as long as 1.0 to 4.0 m. An image inverting optical element consisting of a number of dove prisms arranged in parallel and light intercepting plates interposed between the dove prisms is located immediately behind the positive objective for right-left invertion of the image. A taking lens is located immediately behind the image inverting optical element for focusing an image in the camera in the vicinity of the photographic film. In a preferred embodiment of the invention, a field lens of a focal length equal to or longer than that of the taking lens is located immediately in front of the photographic film.
