Abstract: An anamorphic imaging system is disclosed which maximizes the use of available image area to minimize display magnification and image degradation due to display magnification, reduces the amount of anamorphic squeeze or stretch during photography to lower image degradation due to anamorphosis, and in film applications, utilizes a film frame that is only three perforations in height to reduce the amount of original film needed. The frame for either film or digital applications has an aspect ratio of approximately 16:9, is contained within the total available frame area of a three-perforation frame or digital imager, and is sized to maximize image area. In preferred embodiments, the image capture area is approximately 0.900 inches wide by approximately 0.506 inches tall.

Abstract: A new 35 mm motion picture film is described which minimizes the amount of film stock that is used, and which facilitates industry acceptance by assuring at least present image quality. The new motion picture format (12) has film frames (20) of a size (22, 24) that is slightly greater than that (J, K) of the mask aperture (H) of the current Wide Screen Academy Format. However, the film frames are spaced by a distance (26) that is more than two but less than three times a standard perforation spacing distance (E). The film stock can be different from current film stock, with a perforation spacing distance (48, 68) that results in 2 or 3 perforations per frame.

Abstract: A system is provided for treating sound represented by the varying width of a motion picture film soundtrack, which provides a "flat" frequency response up to 12.5 kHz with maximum phase coherence, even though the film speed is only 62% to 78% of the present speed of 90 feet per minute. The projector photocell which detects a slit-shaped area of light passing through the soundtrack, produces an output that is amplified so the amplification is progressively greater at higher frequencies, with the gain at 12.5 kHz being at least 6 dB greater than at 1 kHz. A photocell is selected whose output at 12.5 kHz is within 1 dB of its output at 1 kHz for light of a wavelength of substantially 1000 nanometers.

Abstract: A new 35 mm motion picture film is described which maximizes usage of film stock, and which facilitates acceptance by motion picture theater owners. Acceptance is facilitated by minimizing the cost for projector head conversion and by assuring at least present image quality. The new motion picture format (12, FIG. 4) has film frames (20) of substantially the same size (22, 24) as the mask aperture (H) of the current Wide Screen Academy Format, and uses the same size and spacing of sprocket holes, or film perforations. However, the film frames are spaced apart by a distance (26) that is a noninteger number of perforations, with the spacing being 2.5 perforations in a preferred format (12). A current projector head is converted for showing the new format, by providing new sprocket wheels (14, FIG. 5) with ten teeth, that mount on the same shafts of the projector head as current sprocket wheels that have sixteen teeth.

Abstract: A sprocket assembly is provided which allows a film projector or any other film handling device to be readily converted to run film having different perforation-to-frame ratios. The sprocket assembly includes an outer cylindrical sleeve having teeth for engaging the film perforations when the film is run, and an inner cylindrical sleeve adapted to fit within and anti-rotationally mate with the outer cylindrical sleeve. The inner sleeve also has teeth for engaging the film perforations. The inner sleeve is mounted on a rotatable shaft of the projector, and the outer sleeve can be added or removed.

Abstract: A multi format shutterless inspection projector for motion picture film whereby the image projected will include a full frame heightwise and margin to margin widthwise to view the picture, sound track and sprocket holes. The apparatus includes condensing lenses, projection lenses and a shutterless film gate mounted therebetween. The illumination means is a strobe light and accompanying apparatus capable of exciting the lamp to micro-second flashes. In addition triggering means is on the projector to fire the strobe light apparatus and the triggering means is geared to the speed of travel of the film through the projector. Further, damping means are provided to control tension on the film as it enters the projector and also there are means to control the speed of the takeup reel motor.

Abstract: A camera in which a standard film, 120 or 220 size is loaded behind the picture plane by using a standard film reel with film spool mounting members and means for guiding and holding the standard film and in which film back exchange is not carried out. The standard film reel is designed to be detachably mounted in the camera through an opening formed in the rear part of a reel accommodating chamber in the camera. The standard film can be replaced by a 70 mm film reel which is provided with mounting members for mounting a 70 mm film magazine outside and reel accommodating chamber and means for guiding said 70 mm film into the reel accommodating chamber and holding it therein. This is designed to be detachably mounted in the camera to thereby allow said camera to commonly use standard film and 70 mm film.

Abstract: A modular film transport and control mechanism for selectively advancing either regular 8mm or super 8mm perforated motion picture film through a projection gate is provided. The module comprises a film transport shuttle having a film engaging claw biased for engagement with the perforations of the film, a rotatable drive cam in operative engagement with the shuttle to reciprocally move the claw along horizontal and vertical paths to advance the film through the projection gate, and a pivotally mounted projection mode shifter interposed between the shuttle and the cam to transmit the desired horizontal motion from the cam to the shuttle, and selectively movable between at least two positions along a surface of the cam to change the mode of operation from normal projection to still projection. A control linkage connected to the shifter permits manual selection of the desired operating mode. The module also comprises a rotatable shutter mounted on a common shaft with the shuttle drive cam.

Abstract: A movie projector for narrow film with sound track is adapted to different operating conditions corresponding, for example, to different sound film types, by means of control inititated by the film itself upon insertion. The leader of the film is provided with markings being disposed outside of the sound track and characterizing the type of film that is appended to the leader. The markings are optically and/or magnetically readable by a pickup device that may be shared with the sound reproduction. The markings as read are counted or assembled and decoded for controlling the operating conditions of the projector concerning, for example, the picture frame rate, the type of sound track, and similar projector conditions. Such markings can also be used on the film proper to change the operating state of the projector automatically during projection.
