Abstract: An optical assembly for three-dimensional image capture includes first and second optical channels that are fixed with respect to one another. Each channel is configured to direct light onto at least a portion of an image sensor. The first and second optical channels each include an aperture for receiving the light, an objective lens for focusing the light into an intermediate image on an intermediate image plane, and an eyepiece lens for collimating the intermediate image.

Abstract: Motion picture images are photographed at forty-eight frames per second, onto motion picture film in the thirty-five millimeter, two-perforation format. These film images are then converted to digital images and re-sized to accommodate an aspect ratio used for wide-screen motion picture exhibition. During exhibition, the images are projected digitally in the 1080 by 2048 or other commercially-used digital exhibition format. The server used for such exhibition is 3D compatible, although the interleaving feature used for three-dimensional exhibition is not used in the present invention. Instead, forty-eight discrete images are projected during each second, matching the forty-eight discrete images per second originally photographed on motion picture film in the practice of this invention. Thus, the present invention combines advantages of film photography in an economical film format with advantages of digital exhibition to theatrical motion picture audiences.

Abstract: The present invention provides a stereo camera 22 for photographing a pair of left and right stereo pictures 1L and 1R in the first frame and the third frame of a continuous film 21, photographing the next pair of left and right stereo pictures 2L and 2R in the second frame and the fourth frame thereof, and repeating similar photographing, wherein the perforation positions of the first frame to the fourth frame are arranged so as to be symmetrical about the center in the longitudinal direction of the first frame to the fourth frame as the center of symmetry for performing photographing.

Abstract: A paper emulsion film product and method for producing the same is shown. The film product includes a first layer of editing tape, a second layer of editing tape, and a layer of paper emulsion formed from a paper reproduction of a photograph sandwiched between the respective layers of editing tape.

Abstract: A process for transferring images from a first frame system to a second frame system is described. A first sequence from the first frame system is determined so as to include a plurality of image frames, wherein each image frame includes a central timing factor. Likewise, a second sequence from the second frame system is selected so as to include a plurality of image frames, wherein each image frame includes a central timing factor. Each image frame for the newly constructed second frame system is built by combining at least two image frames from the first frame system in a proportion such that the central timing factors of the two image frames of the first frame system combine so as to correspond to the central timing factor for the image frame in the second frame system. In this manner, the images from the first frame system combine in a smooth fashion in the second frame system such that jitter, freezes and jumps are eliminated.

Abstract: The reversing film projection system employs film having images printed substantially side-by-side to allow presentation of one set of images in a forward direction and the adjacent images in rearward direction by moving the projection head and associated aperture plate and film guide laterally with respect to the lens and lamp house for display of the film images. In a first forward drive position, the projector motor drives the film in a forward direction with a first aperture of the aperture plate and associated first set of film images aligned with the optical train. Upon completion of the image presentation in the forward direction, the projection head is displaced laterally aligning a second aperture in the aperture plate and the associated second set of film images with the optical train, with the projection motor engaged in a reversed direction.

Abstract: A method of producing and displaying a 3-D motion picture is disclosed. Two master film negatives are prepared using a camera rig employing one camera that looks directly at the subject through a semi-transparent mirror and a second camera that looks at the same subject by way of the reflective surface of the mirror, to obtain left and right eye images. The cameras are oriented so that the mirror images recorded by the second camera are turned laterally of the film in being reflected by the mirror. Contact prints are made from the negatives. Before projecting the images, the contact print from the negative that was shot by way of the mirror is turned about its longitudinal axis so that images on that print are turned laterally. Images from the two prints are simultaneously projected onto the same screen to produce a coincident 3-D image. The left and right eye images are optically coded, for example by using optical filters that are polarized at right angles to one another.

Abstract: A film projector has side-by-side lamphouses each containing a xenon light source, light beam reflectors and a condensor lens for reshaping the reflected circular light beams into horizontal ellipsoidal light beams flattened by masking for the projection of stereo images by a pair of projection lenses having their optical axes coincident with diagonally related images of a stereoscopic image pair. Non-stereo images may likewise be selectively projected.

Abstract: An apparatus for photographing a pair of diagonally related left and right images of a stereoscopic image couple on to film frames of a horizontally moving 65 mm film having 15 film perforations per frame.

Abstract: A method is described for converting a strip of film designed for showing at 60 fps (frames per second) to a film that can be shown at 24 fps. Instead of forming the 24 fps film so it alternately contains every second and every third frame of the 60 fps film, each frame of the 24 fps film includes two distinct overlapping successive images of the 60 fps film.

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.

A filmstrip holder for retaining laterally disposed stereographic images for use with the viewer is also disclosed. Blanks suitable for assembling the viewer and filmstrip holder are similarly described.

Abstract: A stereoscopic picture viewing system having pairs of precisely aligned stereoscopic images arranged in rows on image carriers, with at least two pairs of images on each row, and with one image of each pair located between the two images of a different pair. In one embodiment, the image carriers are circular disks, with the image rows extending radially, and preferably having supplementary key indications at the inner radial ends of each row and in the spaces between the outer ends of successive rows. In another embodiment, the image carriers are long strips of wide film, either still film strips or motion picture film, with the image rows extending transversely across the width of the film strip.

Abstract: A multi-purpose sound/data system which is capable of recording and reproducing a multitude of disparate and dissimilar information being digital and/or analog in nature in such a way so that there is no interference between the different information channels. This system is principally intended to be applied to motion picture film, but it is equally applicable to television and other devices by which sound, data and pictures may be electrically, mechanically or optically recorded and reproduced. It is an important feature that a film recorded with this system can be reproduced by any standard photographic soundhead without alteration, in the same way as a normal photographic soundtrack. This invention confines itself to the layout of the tracks to present a compatible format and does not deal with the methods of recording and reproduction.

Abstract: Stereo pairs which have been printed on a single film strip are directed and focused upon a screen by an attachment for a standard motion picture projector. The images are overlapped and polarized at right angles to the other upon the screen by an optical device having abutting elements. The stereo pairs on the film are separated by an opaque band to define the edges of the projected image and mask element abutment. Indicia marks may be provided on the film to enable the positioning of the right and left images on the film in the gate to avoid pseudo stereo projection. A film format for stereo pairs uses a dark bar centered at the aperture on the film or gate.

Abstract: Stereo pairs suitable for motion picture projection are derived from conventionally taken motion picture film by selection of frames and rearrangement thereof in side by side relationship upon a continuous strip of motion picture film. The pairs so prepared may be incorporated into film containing conventionally photographed stereo frames to provide a compatible system for 3-dimensional motion picture projection.

Abstract: A film splice for joining butted-together film ends, comprising carrier foil bands; a pair of discrete adhesive film-splicing tabs provided on the carrier foil means; and a positioning strip engaging the tabs and operative for positioning the same in predetermined orientation relative to one another when the tabs are respectively adhesively applied to one and to another side of film strips to join together the respective butted-together ends thereof.

Abstract: Each one of three filters, corresponding to different primary subtractive colors of a color picture, is embossed as a relief pattern on the same side of a plastic film within a separate one of any three of four side-by-side regions into which the film is divided. This permits the film to be thrice-folded to both (1) superimpose the three filters substantially in registration with each other and (2) place the embossed side of the film within the interior of the thrice-folded film where said filters are protected.

Abstract: A game simulating a sport such as football employs film sequences of plays of an actual game, using cassettes of film of equal length regularly disposed sequences. A sequence selecting apparatus and projector projects a given sequence determined by the selection of cassettes by one player and selection of sequence by another player. The apparatus employs a take-up reel upon which the film is wound before play to align the beginning of a sequence with an optical projection system, and spiral groove control device coupled to the reel for controlling the rotation of the reel to effect the projection of a single sequence. The optical system projects through apertures in the film cassette, and the shutter is operated by a sprocket coupled to the film.

Abstract: A 180.degree. high resolution fisheye projection lens suitable for projecting images onto a hemispherical dome, such as a planetarium dome, includes a nine-element projection lens and a six-element relay lens. The relay lens serves to increase the distance between the film plane and the lens and eliminates the need for modifying the projector to provide clearance between the lens and the projector shutter mechanism. In addition, the relay lens may be modified to make the fisheye lens compatible with various film sizes without modifying the fisheye lens. A focused iris is used to mask portions of the projected image, and a nonuniformly acting fader is used to reduce back scatter and to stop down the lens to adjust the brightness of the projected image.
