Abstract

Abstract A process for recording camera and exposure information on photographic film, reading the information during photofinishing and re-recording the information magnetically on the film. According to one feature, disclosed with a single use camera, the process includes the ordered steps of recording camera capabilities on the film and then loading the film into a camera having those capabilities. The process further includes the steps of exposing the film in the camera to a scene, processing the film to develop and print the scene using the recorded camera information and re-recording the information magnetically on the film. According to another feature of the invention, disclosed with multiple use cameras, the camera optically records exposure information on the film. The photofinishing operation then reads the optically recorded information, uses the information and magnetically re-records the information on the film.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 62 words
A method of loading a camera having a film supply chamber and a film take-up chamber, comprising steps of: loading a photographic filmstrip into the supply chamber; prewinding the filmstrip from the supply chamber to the take-up chamber; during the prewinding, recording onto the filmstrip information about features and capabilities of the camera; and after the prewinding and recording, closing the camera.
Claim 2
Independent Claim 62 words
A method of loading a camera having a film supply chamber and a film take-up chamber, comprising steps of: loading a photographic filmstrip into the supply chamber; prewinding the filmstrip from the supply chamber to the take-up chamber; during the prewinding, recording onto the filmstrip information about features and capabilities of the camera; and after the prewinding and recording, closing the camera.
Claim 3
Dependent Claim 42 words
A method according to claim 1, wherein the recording is optical, further comprising steps of: exposing the filmstrip in the camera to a scene; processing the filmstrip to develop the recorded information; and making prints of the scene using the recorded information.
Claim 4
Dependent Claim 19 words
A method according to claim 1, wherein the filmstrip includes a magnetic recording layer and the recording is magnetic.
Claim 5
Dependent Claim 47 words
A method according to claim 1, wherein the recording is optical, further comprising steps of: exposing the filmstrip in the camera to a scene; processing the filmstrip to develop the recorded information; decoding the developed, recorded information; and making prints of the scene using the decoded information.
Claim 6
Dependent Claim 68 words
A method according to claim 1, wherein the recording is optical and the filmstrip includes a magnetic recording layer, further comprising steps of: exposing the filmstrip in the camera to a scene; processing the filmstrip to develop the recorded information; decoding the developed, recorded information; magnetically recording the decoded information onto the magnetic recording layer of the filmstrip; and making prints of the scene using the decoded information.
Claim 7
Dependent Claim 14 words
A method according to claim 5, wherein the magnetic recording occurs during making prints.
