Abstract

Abstract A plurality of individual image forming lenses provided in rows and columns in fixed relationship to each other is positioned front of a single film frame upon which rows and columns of small areas are to be exposed to different pictures such as a microfiche. Each lens has associated with it an individual shutter which is normally closed. Any one scene to be exposed to a given area on the film can be exposed by opening only the shutter associated with the corresponding lens positioned to project the scene on the particular area. Thus by sequentially opening and closing the various shutters as the scenes are changed, multiple images are formed on the main film frame in desired rows and columns without having to move the film itself or the camera. A reverse procedure is provided for reading out any one of the individual pictures formed on the film.

Claim 1
Independent Claim 235 words
A multiple image film exposure system comprising, in combination: display means for successively displaying a plurality of pictures to be photographed onto a single film frame to provide a plurality of individual pictures on small areas on said frame in a desired pattern; a camera including gate means for supporting said film frame; means defining a plurality of individual image forming lenses positioned in front of said gate means to project multiple images of one of said pictures on said film frame, said images respectively occupying said small areas in said desired pattern; an individually operable normally closed shutter means for each of said individual image forming lenses so that opening and closing of a selected shutter means exposes a corresponding area of said film frame to the particular picture displayed by said displaying means; a synchronizing means connected between said display means and said individually operable shutter means for automatically successively opening and closing said shutter means in a sequence defining said desired pattern, said synchronizing means including means for generating a different control signal in response to changing of a picture on said display means, each of said shutter means being responsive to a particular control signal received to open and close; and a delay means for delaying the arrival of the control signal to assure that the shutter to be operated is not operated until the picture to be displayed is steady.
