Abstract
Abstract Recording of data segments on film in a photographic still camera continuously along a length of film spanning interframe locations between image frame regions is interrupted at predetermined intervals corresponding to multiples of image frames at which the film is normally cut into strip at a photofinishing facility. Codes are recorded at the beginning and end of a recorded segment and upon recommencement of recording following each interruption such that continuous, uninterrupted playback of the data segment is facilitated.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
85 words
A photographic camera with data recording on film comprising: data signal recording means for recording data in the camera in a data segment extending continuously along a stretch of photographic film spanning at least one interframe location between successive standard image frame areas on the film; and control means for interrupting said continuous recording during those interframe locations occurring at predetermined intervals of at least four successive image frame lengths corresponding to intervals at which said film is cut into strips at a photofinishing facility.
Claim 2
Dependent Claim
85 words
A photographic camera with data recording on film comprising: data signal recording means for recording data in the camera in a data segment extending continuously along a stretch of photographic film spanning at least one interframe location between successive standard image frame areas on the film; and control means for interrupting said continuous recording during those interframe locations occurring at predetermined intervals of at least four successive image frame lengths corresponding to intervals at which said film is cut into strips at a photofinishing facility.
Claim 3
Dependent Claim
38 words
A photographic camera according to claim 1, wherein said recording is interrupted during interframe locations occurring at intervals of multiples of 4, 5, or 6 standard image frame lengths measured from a common starting point on the film.
Claim 4
Dependent Claim
28 words
A photographic camera according to claim 1, wherein said recording means includes a magnetic record head for recording said data on a magnetic layer formed on the film.
Claim 5
Dependent Claim
27 words
A photographic camera according to claim 3, wherein recording head is so positioned in the camera to record over optically exposed image frame areas on the film.
Claim 6
Dependent Claim
24 words
A photographic camera according to claim 1, wherein said recording means includes an optical record head for recording said data optically on the film.
Claim 7
Dependent Claim
45 words
A photographic camera according to claim 1, wherein said control means includes means for recording a header at the beginning of the segment including a data segment identification code and a trailer sequence at the end of the segment including an "end of segment" code.
Claim 8
Dependent Claim
19 words
A photographic camera according to claim 6 wherein said header includes a code identifying an associated exposed image frame.
Claim 9
Dependent Claim
50 words
A photographic camera according to claim 6 wherein said control means further includes means for recording a continuation header following an interruption in data segment recording at an interframe location, the continuation header including said data segment identification code and the number of previous interruptions in the recorded data segment.
Claim 10
Dependent Claim
12 words
The camera of claim 1 wherein said recorded data is audio information.
Claim 11
Dependent Claim
13 words
The camera of claim 1 wherein said recorded data is digitized image information.
Claim 12
Independent Claim
133 words
A method of recording data on a photographic film strip along a length thereof spanning interframe locations between standard image frame regions on the film comprising: recording a header string at the beginning of the recording of a data segment, the header string including an identification code for the data segment; interrupting said recording periodically at those interframe locations corresponding to multiples of frame lengths at which the film strip is cut at a photofinishing facility; upon recommencement of the recording after the interruption, recording a continuation header giving said data segment identification code and the number of interruptions in the recorded data segment up to this point of recommencement; and upon completion of recording of the data segment, recording a trailer sequence giving the data segment identification code and an end-of-segment code.
Claim 13
Independent Claim
133 words
A method of recording data on a photographic film strip along a length thereof spanning interframe locations between standard image frame regions on the film comprising: recording a header string at the beginning of the recording of a data segment, the header string including an identification code for the data segment; interrupting said recording periodically at those interframe locations corresponding to multiples of frame lengths at which the film strip is cut at a photofinishing facility; upon recommencement of the recording after the interruption, recording a continuation header giving said data segment identification code and the number of interruptions in the recorded data segment up to this point of recommencement; and upon completion of recording of the data segment, recording a trailer sequence giving the data segment identification code and an end-of-segment code.
