Claims
- 1. A photographic film on which an image to be photographed is optically recorded, comprising:
- a plurality of image frames; and
- a single recording portion provided in association with each one of said image frames for recording image information associated with said image frame, said recording portion including two or more contiguous fields running along a direction in which said photographic film is conveyed so that two or more sections of image information are recorded in said fields, each of said sections of image information consisting of a portion of said image information and provided with at least a corresponding start signal and a corresponding end signal.
- 2. A photographic film according to claim 1 wherein each of said image information sections is further provided with at least one of a corresponding error detection signal and a corresponding error correction signal.
- 3. A photographic film according to claim 2 wherein each of said fields is arranged such that said corresponding start signal, one of said sections of image information, said corresponding end signal and at least one of said corresponding error detection signal and said corresponding error correction signal are recorded on said fields in that order.
- 4. A photographic film according to claim 1 wherein said recording portion comprises at least one magnetic track formed on a magnetic recording layer provided on said photographic film.
- 5. A photographic film according to claim 4 wherein said magnetic track is formed at a portion of said photographic film so as not to be superimposed on said image frame.
- 6. A photographic film according to claim 4 wherein said magnetic track extends in a direction parallel to a longitudinal direction of said photographic film, and a length of said magnetic track is substantially the same as a length of said image frame as measured in the longitudinal direction of said photographic film.
- 7. A photographic film according to claim 1 wherein more important of said image information sections is recorded on a front field of said two or more fields, as viewed in a direction in which said photographic film is conveyed.
- 8. A photographic film according to claim 1 further comprising a second recording portion at a front end portion of said photographic film for recording film information relating to said photographic film.
- 9. A photographic film according to claim 8 wherein said second recording portion includes two or more second fields running along a direction in which said photographic film is conveyed so that two more film information sections, each consisting of a portion of said film information are each provided with at least a corresponding start signal, a corresponding end signal, and at least one of a corresponding error detection signal and a corresponding error correction signal.
- 10. A photographic film comprising:
- a base;
- an emulsion layer provided on one surface of said base for optically recording a photographed image in a plurality of image frames;
- a substantially transparent magnetic recording layer provided on the other surface of said base for magnetically recording information; and
- at least one magnetic track formed in association with each individual image frame on said magnetic recording layer and extending in a direction parallel to a longitudinal direction of said photographic film, said tracks each including two or more contiguous fields running along a direction in which said photographic film is conveyed so that two or more sections of information, which are recorded in one of said fields and consist of a portion of said information, are each provided with at least a corresponding start signal, a corresponding end signal, and at least one of a corresponding error detection signal and a corresponding error correction signal.
- 11. A photographic film according to claim 10 wherein more important of said information section is recorded on a front field of said two or more fields, as viewed in a direction in which said photographic film is conveyed.
- 12. A method of recording information on a photographic film for recording information relating to each image frame of said film on a recording portion provided in association with each one of said image frames, comprising the steps of:
- (a) dividing information to be recorded on said recording portion into two or more sections of information; and
- (b) recording each of said sections of information in a contiguous manner together with at least a corresponding start signal and a corresponding end signal for said each of said sections of information while conveying said photographic film.
- 13. A method of recording information on a photographic film according to claim 12, wherein said step (b) further comprises recording at least one of a corresponding error detection signal and a corresponding error correction signal together with each of said information sections.
- 14. A method of recording information on a photographic film according to claim 13, wherein during said step (b) said start signal, said sections of information, said end signal, and at least one of said error detection signal and error correction signal for said information are recorded in that order.
- 15. A method of recording information on a photographic film according to claim 12 wherein said step (b) begins after a perforation provided at a front end portion of each image frame is detected.
- 16. A method of recording information on a photographic film according to claim 12 wherein said recording portion comprises at least one magnetic track formed on a magnetic recording layer provided on said photographic film.
- 17. A method of recording information on a photographic film according to claim 16 wherein said magnetic track is formed at a position so as not to be superimposed with said image frames of said photographic film.
- 18. A method of recording information on a photographic film according to claim 12 wherein more important information of said divided information is recorded on a forward portion of said recording portion as viewed in a direction in which said photographic film is conveyed.
- 19. A method of recording information on a photographic film according to claim 12 wherein said information is recorded by a magnetic head provided in a photographing camera.
- 20. A photographic device having film on which an image to be photographed is optically recorded, comprising:
- a plurality of image frame areas extending along the length of said film;
- a data recording portion associated with each of said image frames, said data recording portions being contiguous and extending in a direction of transport of said film;
- a plurality of start signals provided in each of said data recording portions; and
- a stop signal associated with each of said start signals.
- 21. A method of recording information on a recording track formed on photographic film, said recording track corresponding to an individual image frame formed on said film and positioned in an exposure position of a camera, said method comprising the steps of;
- transporting said film in a first direction to displace said individual image frame from said exposure position and to place an adjacent image frame at said exposure frame;
- recording said information on said recording track during said transporting step, said information being recorded as a plurality of sections of information arrayed in said first direction, each of said sections of information having a start signal and a stop signal associated therewith.
