Abstract: A stereo photographic system capable of reproducing a correct stereo image by improving the precision of positions for mounting the films on a stereo slide mount. Positions of the projected images of perforation of the films relative to the focusing plates are measured when a suitable perspective feeding is obtained by using a detecting device that projects the pictures of the films onto a pair of right and left focusing plates and that adjusts the gap between the right and left projected pictures to adjust the perspective feeling. A printer device 81 drives a printer head 87 based upon the position data that are measured, and prints indexes on a base frame 51a of the stereo slide mount to accomplish the positioning with respect to the perforations.

Abstract: A dual-lens camera which can be used to take single-frame images for 2D photography or dual-frame images for 3D photography. The camera has two taking lenses and two independently operable shutters. The unique feature of this dual-lens camera is that the camera comprises two shutter release buttons. On release button activates only the shutter associated with one taking lens to take a single-frame image. The other button activates both shutters to take a stereo image pair. A film advance mechanism is used to advance the film in accordance with the operating mode of the camera.

Abstract: A stereo camera optimally corrects a parallax despite a photographing distance. Lens boards of right and left photographing lenses are mounted with slide guides for obliquely feeding in an inter-optical axis distance approaching direction as the lens boards are fed. When a focusing knob is rotated, the photographing lenses and a finder lens are integrally advanced or retracted in response to the rotating direction of a cam shaft. The slide guides are so disposed that the right and left visual fields are brought into agreement at a close distance at the close distance photographing and the right and left visual fields are brought into agreement at the close distance as compared with the focal distance at the time of remote distance photographing. Accordingly, the unnatural of the remote or close distance feeling generated by the influence of the close distance subject at the human collimation at the time of remote distance photographing, and ideal stereo effect is obtained at all the photographing distances.

Abstract: A multi-format scanner, has first and second laterally spaced film gates which are dimensioned to accomodate film of respective different widths lengthwise therethrough for scanning. Each gate has an aperture through which light can pass. A light source illuminates film at the aperture of at least a selected one of the gates. A sensor receives light from the light source which has passed through film at the aperture of the selected gate. A film input and output track set is aligned with the selected gate to lengthwise convey elongated film of either width, into and out of the selected gate. A drive moves the film lengthwise through the selected gate. At least one of: the film gates, the sensor or track set, can be laterally moved so that either gate can serve as the selected gate.
