Abstract
Abstract A novel system is disclosed which is suitable for addition to conventional photographic cameras for permitting recording of data such as f-stop and shutter speed annotations automatically on film as thecamera is operated in conventional photography. The system of the present invention includes a light emitting diode display mounted inside a camera back and positioned adjacent the edge portions of film within the camera. A pair of rotary or slide switches are mechanically coupled to the f-stop and shutter speed controls of the camera to trigger the appropriate light emitting diodes for recording the camera settings on the edges of the film. The system may be incorporated into new cameras as they are manufactured, or it may be distributed as a kit for addition to existing cameras.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
226 words
A system for automatically recording images representative of camera settings on film comprising: first multiple position selector switch means adapted to be coupled to an aperture setting mechanism of said camera for identifying selected aperture settings thereof; first display means including a first plurality of light emitting electroluminescent devices adapted to record coded images on said film, said electroluminescent devices selectively energizable to form a plurality of said coded images, each corresponding to a predetermined setting of said first selector switch; a first plurality of electrical conductors coupling said electroluminescent devices in first display means and first selector switch means for permitting selection of said coded images whereby camera aperture settings may be indicated on said film; second multiple position selector switch means adapted to be coupled to an exposure time setting mechanism of said camera for identifying selected exposure time settings thereof; second display means including a second plurality of light emitting electroluminescent devices adapted to record coded images on said film, said electroluminescent devices selectively energizable to form a plurality of said coded images, each corresponding to a predetermined setting of said second selector switch; and, a second plurality of electrical conductors coupling said electroluminescent devices in second display means and said second selector switch means for permitting selection of said coded images whereby camera exposure time settings may be indicated on said film.
Claim 2
Independent Claim
226 words
A system for automatically recording images representative of camera settings on film comprising: first multiple position selector switch means adapted to be coupled to an aperture setting mechanism of said camera for identifying selected aperture settings thereof; first display means including a first plurality of light emitting electroluminescent devices adapted to record coded images on said film, said electroluminescent devices selectively energizable to form a plurality of said coded images, each corresponding to a predetermined setting of said first selector switch; a first plurality of electrical conductors coupling said electroluminescent devices in first display means and first selector switch means for permitting selection of said coded images whereby camera aperture settings may be indicated on said film; second multiple position selector switch means adapted to be coupled to an exposure time setting mechanism of said camera for identifying selected exposure time settings thereof; second display means including a second plurality of light emitting electroluminescent devices adapted to record coded images on said film, said electroluminescent devices selectively energizable to form a plurality of said coded images, each corresponding to a predetermined setting of said second selector switch; and, a second plurality of electrical conductors coupling said electroluminescent devices in second display means and said second selector switch means for permitting selection of said coded images whereby camera exposure time settings may be indicated on said film.
