Abstract

A film camera for recording visual images is adapted to record sound accompanying a photographic event onto the film section used for the visual image of such event. This audio recording is accomplished with light, immediately or at any time prior to taking the next photograph. The audio recording is accomplished without substantial intrusion into the photographic image. This system utilizes the film, processing, and printing currently available to the consumer or amateur photographer. The film camera captures and stores sound in a digital binary form then imprints this binary code onto film in the form of black and transparent bars adjacent the actual negative light image. A reading device (110) accesses and makes audible the recorded audio from photographs. A receptacle (139) provides storage of multiple photographs and instant access to audio and visual information stored. A processor which isolates and monitors a static electrical field surrounding the photographs in the receptacle. This static field monitoring facilitates the selection of specific photographs and their respective audio segment, when the user touches a specific photograph, thereby interrupting that field.

Claims19

Dependent claims

A system for concurrently and contiguously recording, onto a light-sensitive film, a visual image and associated audio related information, said system comprising:

(a) recording means for recording said visual image onto a section of said light-sensitive film,
(b) gathering means for gathering sound from an area in proximity to said recording means,
(c) translating means for translating said sound into an electrical audio signal representative of said sound,
(d) storage means for temporarily storing a predetermined duration of said electrical audio signal,
(e) conveyance means for moving said light-sensitive film past a fixed station,
(f) determining means for determining the rate of speed at which said light-sensitive film moves past said fixed station,
(g) imprinting means for imprinting onto said section of said light-sensitive film, said electrical audio signal as stored, said imprinting means being arranged to create a longitudinal track of information as a series of light and dark contrasting areas adjacent said visual image as recorded,
(h) adjusting means for adjusting the rate of said imprinting of said electrical audio signal as stored, to a rate of imprinting corresponding to said rate of speed at which said light-sensitive film moves past said fixed station,
(i) imprinting means for concurrently imprinting a second signal representative of said rate of speed said electrical audio signal is imprinted onto said section of said light-sensitive film, at a predetermined position relative to said electrical audio signal as imprinted, said second signal being imprinted as a series of light and dark contrasting areas in a longitudinal direction, and
(j) imprinting means for imprinting an alignment reference onto said section of said light-sensitive film as a light and dark contrasting area adjacent said electrical audio signal as imprinted, said imprinting occurring at a predetermined position relative to said electrical audio signal as imprinted,
whereby the minimum size of all said audio related information as imprinted, is limited only by the resolution of said light-sensitive film, and said imprinting of said audio related information and said moving of said light sensitive film, can occur at a variable rate of speed.

8 more elements

A system for accessing audio related information imprinted concurrently and contiguously with a visual image onto a light-sensitive film, after said light sensitive film has been developed and printed onto a photographic paper, said imprinting of said audio information arranged as a series of light and dark contrasting areas in a longitudinal manner, said system comprising:

(a) accessing means for concurrently accessing an electrical audio signal representative of a sound having a predetermined duration, and a second signal representative of a ti me-base indicating said predetermined duration, as printed to said photographic paper,
(b) conveyance means for moving said photographic paper in a longitudinal direction past said accessing means,
(c) alignment means for aligning said accessing means to a predetermined position relative to said audio related information as printed onto said photographic paper, as said photographic paper moves past said accessing means in a longitudinal direction,
(d) a temporary storage medium for temporarily storing said electrical audio signal as accessed,
(e) a temporary storage medium for temporarily storing said second signal as accessed,
(f) transforming means for transforming said second signal as stored, to a time base representative of said predetermined duration,
(g) transforming means for transforming said electrical audio signal as stored to an audible form, and
(h) regulating means for regulating rate of said transforming of said electrical audio signal as stored to said audible form, said rate of said transforming being dictated by said time base, said audible form being representative of said sound having said predetermined duration,
whereby said accessing, and said transforming of said audio related information as printed, and said passing of said photographic paper can occur at a variable rate of speed.
