Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
181 words
A method of making a wide screen picture on 35mm film having a plurality of edge perforations at longitudinally spaced intervals along the length of the film having a standard perforation pitch length comprising the steps of: a. photographing a scene on an original film to provide photographic images having a frame length in the direction of the longitudinal extent of the film no greater than three perforation pitch lengths; b. repeatedly thereafter advancing said original film a distance equal to three perforation pitch lengths and photographing a plurality of successive scenes to provide successive photographic images each having a frame length no greater than three perforation pitch lengths; c. processing and finishing said original film to provide a finished original suitable for printing; and d. subsequently preparing print films having edge perforations having the same standard pitch length by printing successive original film frame images onto said print film by successively advancing the original film in a series of lengths measuring three perforation pitch lengths and successively advancing the print film in a series of lengths measuring four pitch lengths.
Claim 2
Independent Claim
181 words
A method of making a wide screen picture on 35mm film having a plurality of edge perforations at longitudinally spaced intervals along the length of the film having a standard perforation pitch length comprising the steps of: a. photographing a scene on an original film to provide photographic images having a frame length in the direction of the longitudinal extent of the film no greater than three perforation pitch lengths; b. repeatedly thereafter advancing said original film a distance equal to three perforation pitch lengths and photographing a plurality of successive scenes to provide successive photographic images each having a frame length no greater than three perforation pitch lengths; c. processing and finishing said original film to provide a finished original suitable for printing; and d. subsequently preparing print films having edge perforations having the same standard pitch length by printing successive original film frame images onto said print film by successively advancing the original film in a series of lengths measuring three perforation pitch lengths and successively advancing the print film in a series of lengths measuring four pitch lengths.
Claim 3
Dependent Claim
51 words
A method as claimed in claim 1, wherein said successive original film frame images are printed without enlargement onto said successive print film lengths measuring four perforation pitch lengths, whereby the print films may be projected by conventional projectors adapted to advance print films a total of four perforation pitch lengths.
Claim 4
Dependent Claim
29 words
A method as claimed in claim 1 wherein the photographic images of the original film are anamorphic images having a horizontal reduction in the range of 1.5:1 to 1.25:1.
Claim 5
Dependent Claim
96 words
A method as claimed in claim 3 wherein said anamorphically reduced images of the original film are longitudinally stretched during the preparation of the print film on to frames of the print film measuring four perforation pitch lengths so as to provide a print film bearing anamorphically longitudinally stretched photographic images having a 2:1 horizontal anamorphic reduction ratio whereby the film may be projected by means of a conventional projector having an anamorphic optical system of a 2:1 ratio to provide a projected image without anamorphic distortion having a width to height ratio of about 2.35:1.
Claim 6
Dependent Claim
67 words
A 35mm film having a plurality of edge perforations having a standard perforation pitch length of about 0.1866 inches and the film bearing a plurality of photographic images of standard width, each image being located on adjacent lengths of the film measuring about 0.5598 inches, each image having a length in the longitudinal extent of the film measuring in the range of 0.446 inches to 0.5598 inches.
Claim 7
Dependent Claim
67 words
A 35mm film having a plurality of edge perforations having a standard perforation pitch length of about 0.1866 inches and the film bearing a plurality of photographic images of standard width, each image being located on adjacent lengths of the film measuring about 0.5598 inches, each image having a length in the longitudinal extent of the film measuring in the range of 0.446 inches to 0.5598 inches.
Claim 8
Dependent Claim
26 words
A 35 mm film as claimed in claim 5 wherein the length of the photographic image is in the range of 0.446 inches to 0.550 inches.
