Abstract: An image conversion apparatus includes an image signal input unit repeatedly inputting an odd-numbered frame of a first parallax, an odd-numbered frame of a second parallax, an even-numbered frame of the first parallax, and an even-numbered frame of the second parallax, in this order; a frame memory storing the first and second parallax data having been input; a memory control unit alternately reading as field data (m+1) pieces (m is an integer of one or larger than one) of identical odd-numbered frames of the first parallax and m pieces of identical odd-numbered frames of the second parallax, and subsequently alternately reading as field data m pieces of identical even-numbered frames of the first parallax and (m+1) pieces of identical even-numbered frames of the second parallax; and an image output unit outputting the field data having been read.

Abstract: A photographic camera for three dimensional photography. The photosensitive material is positioned at a fixed location during the exposure cycle of the camera. Optics projects the light from a scene to be photographed along an optical path onto the located photosensitive material. A lenticular screen is positioned in the optical path and adjacent the location for photosensitive material. The path of light from the scene is blocked and an optical aperture is passed across the optical path for sequentially exposing the photosensitive material through the lenticular screen to the light rays from the scene. A lenticular screen is moved a predetermined distance along a path transverse to the path of the light simultaneously with the movement of the optical aperture. The arrangement for moving the lenticular screen comprises means for guiding the screen along said predetermined path and a pivoted member, a connection between the pivoted member, at a position displaced from the pivot thereof, and the screen.
