Abstract
Abstract An identification camera system for producing an identification type card having a composite image of both a subject and a data bearing card and for producing an encoded film record of the identification card includes a first lens for photographing the subject and a second lens for photographing the data card. The light from the subject and the data card is polarized in orthogonal planes and directed by a beam splitter through image analyzers onto mutually exclusive areas of first and second image planes. Self-developing film of the type marketed by Polaroid Corporation, for example, is located at the first image plane and, after exposure to the optically resolved subject and data card images, is developed to form the identification card, and strip film, e.g., a super 8 mm movie-type film contained within a movie camera, is located at the second image plane and receives an optically resolved subject and data card exposure identical to that received by the self-developing film to provide a permanent record of the identification card. Encoding means are provided to uniquely encode each frame of the strip film record with information, e.g. the serial number, frame number, and like information, to enable convenient retrieval of the identification card record.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
196 words
In an identification camera system of the type that provides a composite subject/data identification card and a photo record of the identification card and which has a housing that contains a subject optical system for directing light from a subject to a subject area of an identification card image plane and to a subject area of a photo record image plane and a data optical system for directing light from a data carrier to a data area of an identification card image plane and to a data area of a photo record image plane, the respective subject and data areas of the identification card image plane and the photo record image plane being mutually exclusive, the photo record image plane located at a film plane within a recording camera, the improvement comprising: an optical compensation means for compensating the respective focal lengths and angles of the subject and data image paths to direct their images to the photo record image plane, said compensating means having a first lens arrangement for focusing the data image on the photo record image plane, and a second lens for compensating the subject image directed to the photo record image plane.
Claim 2
Dependent Claim

In an identification camera system of the type that provides a composite subject/data identification card and a photo record of the identification card and which has a housing that contains a subject optical system for directing light from a subject to a subject area of an identification card image plane and to a subject area of a photo record image plane and a data optical system for directing light from a data carrier to a data area of an identification card image plane and to a data area of a photo record image plane, the respective subject and data areas of the identification card image plane and the photo record image plane being mutually exclusive, the photo record image plane located at a film plane within a recording camera, the improvement comprising: an optical compensation means for compensating the respective focal lengths and angles of the subject and data image paths to direct their images to the photo record image plane, said compensating means having a first lens arrangement for focusing the data image on the photo record image plane, and a second lens for compensating the subject image directed to the photo record image plane.
Claim 3
Dependent Claim
19 words
The system of claim 1 wherein said second lens both focuses and angularly redirects the subject image optical path.
Claim 4
Dependent Claim
24 words
The system of claim 2 wherein said first lens arrangement and said second lens are planar Fresnel elements formed in a compact sandwich assembly.
Claim 5
Dependent Claim
34 words
The system of claim 3 wherein the first lens arrangement comprises: a pair of Fresnel lenses located on respective sides of said second lens in registration with both said subject and said data images.
Claim 6
Dependent Claim
35 words
The system of claim 4 wherein the improvement further comprises: a diffuser plate located in the data image optical path; and said second lens is located in a cut out portion of said diffuser plate.
Claim 7
Dependent Claim
35 words
The system of claim 1 wherein said second lens is a Fresnel wedge formed from an off axis section of a negative Fresnel lens to both focus and angularly redirect the subject image optical path.
Claim 8
Dependent Claim
23 words
The system of claim 1, further comprising: means for adjusting the position of the strip film plane relative to the recorded image plane.
Claim 9
Dependent Claim
19 words
The system of claim 7 wherein said adjusting means permits adjustment of said recording camera about two orthogonal axes.
Claim 10
Dependent Claim
63 words
The system of claim 1, further comprising: first display means for imaging an encoded identification character on at least one of said image planes, said first display means comprising a display board mounted outside of said camera system's image path, and a mirror mounted in said image path to receive and redirect the image of said display board to said one image plane.
Claim 11
Dependent Claim
40 words
The system of claim 9, further comprising: second display means mounted in a position on said camera system to be visually accessible to an apparatus operator for displaying the identification character identical to that displayed by said first display means.
