REDUCED-SIZE MOTION PICTURE FILMS AND THE PHOTOGRAPIIING AND PROJECTION THEREOF This a continuation of application Ser. No. 515,092, filed Dec. 20, i965, now abandoned.
The present invention relates to photographic processes whereby tremendous amounts of motion picturefilm and related materials may be saved as compared to conventional processes.
In previous practice, the standard frame dimensions for a 35 mm. film, for example, have been 22x16 mm., on which photographing and projection have been accomplished.
Such practice has required vast quantities of film and the silver contents thereof in photographing and printing motion picture films. In addition, the related labor costs have been enormous for such workers as cameramen, assistants, projection engineers in the motion picture theater, carriers of raw film and motion picture and other films, repairers of motion picture film, supervisors of various films in storage, and so forth, with the result that the accumulated labor cost and the ever increasing space for storingthe films have placed the motion picture industry in a financial predicament. These disadvantages, are in fact daily aggravated by the current trend of the motion picture industry toward longer films and wider screens.
An object of the present invention is to provide a new halfsize motion picture film to adequately improve the aforementioned defects of the motion picture industry.
Another object of the present invention is to provide a method of manufacturing and projecting the half-size motion picture film.
Another object of the invention is to provide a photographic process for producing wide screen pictures with a saving of one-half the amount of film normally expended on wide screen pictures.
This invention provides a motion picture film which is a continuation of frames having sizes which are vertically reduced by one-half as compared with the standard size and wherein the number of frames driven per unit time is equal to that of the standard-size motion picture film while the driven quantity of the film is designed to be one-half of the standard size.
Furthermore, the half-size motion picture film provided by the invention is a continuation of frames vertically reduced by one-half of the standard size and also with the sound-recorded part as one-half of the standard size moreover, the number of frames driven per unit time is equal to that of the standard-size motion picture film while the driven quantity of the. film is designed to be a half of the standard-size motion picture film.
The half-size motion picture film involves the photographing and restorative projecting system based on anamorphous images and the photographing and projecting system based on slightly anamorphous or right images.
The invention provides a method of photographing and projecting by means of the half-size motion picture film, which method comprises the exposure of raw film by the use of an anamorphous optical system in order to obtain anamorphous images reduced by one-half in size in the vertical direction (including the horizontally reduced images by the anamorphous lens) as against the horizontal direction of the photographed scenes, the development of such film to produce a negative which is a continuation of frames with vertically reduced images formed on each frame, the printing of the negative to produce the positive, and the projection of right images on the screen by the use of an anamorphous optical system of the projector so that the obtained images may be extended and restored in inverse proportion to the reduced anamorphous images. This motion picture film can be viewed not on the socalled wide screens but on the standard-size screen.
Moreover, the invention provides another method of photographing and projecting by means of the half-size'motion picture film, which method comprises the exposure and photographing of the motion picture film by the use of a certain optical system in order to obtain right or slightly anamorphous images, i.e., undistorted images on the film reduced by one-half in size in the vertical direction, the development of the film to produce a negative vertically reduced film on which right or slightly anamorphous images are formed, and the obtaining of wide or standard-sized motion pictures from the images on the film thus obtained by means of a certain optical system.
The reverse film may be used in the photographing and projecting of the motion picture film of the invention which is a continuation of the compressed or reduced images. In this case, the positive film may be obtained immediately through development after photographing, with the otherwise required intermediate process of printing from the negative to the positive being omitted.
In relation to the photographing and projecting of each type of the above-discussed half-size motion picture film, the following machinery is found to be preferable and required.
Such machinery contains a half-size motion picture film photographing equipment which mainly consists of means to feed raw film, a system of kinematographic lenses, a mechanism equipped with an intermittent raking claw of a stroke reduced by one-half as compared with the standard camera, and an aperture vertically reduced to one-half of the standard size, in order to take the vertically reduced images compared with the standard size on raw film.
Such machinery also contains a half-size motion picture film projector which consists of a projecting mechanism and a sound-regenerating mechanism which handle the motion picture film with images vertically reduced to one-half of the standard size. The projecting mechanism comprises a system of projecting lenses, a driving mechanism with the same number of revolutions of the filmdriving sprocket as the standard projector and with one-half the number of teeth on the sprocket as compared to the standard projector, and an aperture region with apertures vertically reduced one-half in size. The sound-regenerating mechanism comprises a driving means with its film-driving speed reduced by half and a slit mirror with the width of the slit being one-half the normal size.
However, the sizes of motion picture film now in prevalent use are 35 mm., 70 mm., or 16 mm., so that it is considered to be especially desirable to provide a changeover type of projector which can use both the standard motion picture film and the half-size motion picture film of the present invention.
Details of the objects, constructions, features, performances, and effects of this invention other than described above will be clarified in the following explanation made with reference to the accompanying drawings wherein:
