Abstract: A motion picture film includes a plurality of frames, with each frame formed of a first and second sub-frames. Each of the first and second sub-frames encompasses an image of a separate one of first and second sequences of successive images independent of each other. The first and second sequences of images typically undergo display one prior to the other, by projecting the film twice in succession, the first time to display the images in the first sequence, the second time to display the images in the second sequence. The film also carries two separate sets of sound tracks, each corresponding to separate one of the first and second sequences of successive images for separate playback.

Abstract: A photographic method and apparatus for producing a motion picture including moving a film unit in one direction and the optics system along an arcuate path generally laterally thereto so as to produce a plurality of images on the film unit. The camera utilizes means for intermittently moving the film unit, such as a film card, in a first direction with the image produced in sequence in a plurality of parallel, arcuate rows generally laterally of the first direction. Alternate rows of images are produced along a first lateral direction while intervening rows thereof are produced along a second lateral direction opposite to the first one.

Abstract: An improved motion picture apparatus for use with a card-like film unit and being of the type including a rotatable barrel cam for reciprocally driving the optical output end of a pivoting periscope boom, forming part of a scanning optical system, stepwise along a given locus over a row of sequential image positions at the film plane wherein the improvement comprises structure for axially displacing the barrel cam to adjust the location of the given locus so that at each of the steps the output end is in registration with a corresponding one of the image positions.

Abstract: An editing device for use with film units having a plurality of images thereon. A film unit is placed in such device in a manner such that selected images which are desired to be viewed, as in a film projection apparatus, are identifiably presented to the user of the device. The projection apparatus is designed to monitor the white border of the film unit and to rapidly advance the latter to thereby eliminate projection of given portions when a black surface is sensed, and the editing device presents to the user both the selected frames and selected portions of the surface of the film unit corresponding to such identified images. The light reflecting characteristics of such selected surface portions are then suitably altered, as by blackening thereof to make them effectively light absorbent so as to control subsequent projection. Re-editing of the previously edited portions can occur by whitening portions or all of the previously blackened portions of the film unit.

Abstract: A motion picture camera for producing a plurality of sequential images in a film unit wherein the film unit moves in a first direction and the optics system moves along an arcuate path generally laterally with respect to the direction in which the film unit moves such that the images are produced in sequence in a plurality of parallel, arcuate rows generally laterally of the first direction. The optics system for producing such images is mounted on a rotating boom, the pivot axis of the boom substantially coinciding with the input axis of the camera and the output axis of the optics system being offset from the input axis by a distance which remains fixed during the rotation. Responsive to camera actuation, each film unit is advanced step by step between production of each image row and, following formation of a last row, the unit is advanced into a spread roll system. Release of the camera actuator then operates the spread roll system to process and eject the film and also to reset the film advance.

Abstract: A photographic projection apparatus for use with a film unit which has a plurality of images formed in a plurality of arcuate rows thereon supports the film unit between a light source and an optics system, both of which move along an arcuate path corresponding in shape to that of the arcuate rows of images on the film unit. The film unit is intermittently moved in a direction normal to the scan of the image rows so as to provide a sequential scan of the images in successive rows whereupon the images are projected onto a screen.

Abstract: A photographic viewing system for use with a film unit having images formed in arcuate, or crescent-shaped, rows thereon. The system utilizes a fixed light source for directing light to a selected arcuate row of images which are to be sequentially viewed and an optics system moves along an arcuate path which corresponds to such selected arcuate row of images so as to produce sequential optical images representing the image on the film unit. A viewing means, such as a monocular eyepiece member or a projection system, provides for the viewing of the optical images that are so produced. The rate of image production is controlled by control of a variable speed motor by the operator. The overall system can be fabricated as a compact, lightweight hand-held unit.

Abstract: A method of recording images on a photosensitive medium by making successive exposures of an object on to the medium through an array of lens elements adjacent the medium, each exposure producing a plurality of recorded sub-images on the medium, and moving appropriate parts of the system relative to each other between successive exposures so as to produce separation of the sub-images of the successive exposures.
