Abstract
Abstract A camera system for the simultaneous and substantially exact capturing of images of a subject on separate image reproduction mediums wherein an optical member is interposed between a lens group and a pair of separate, discrete image receiving mediums. One of the mediums is a photographic film and the other is a viewing screen for personal viewing or, alternatively, an electronic system for electronic signal generation, electronic viewing and electronic capture of the image. The optical member allows light rays emanating from the object to pass therethrough to impinge upon one of the mediums while simultaneously reflecting light rays to the second medium. This system allows for the simultaneous transfer and reproduction of the object image onto more than one medium without degradation of the image or depth of field. The system accomplishes the multiple image transfer through a stationary device, thereby eliminating the necessity of moving parts. The system also eliminates problems resulting from refractions of light normally accompanying light ray direction control devices.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
217 words
A camera system for simultaneous and substantially total transfer of light rays from an object to separate, discrete mediums providing identical image reproduction at the mediums, said system including: a. a front lens structure arranged and constructed to receive light rays from the object and to direct the same axially thereof; b. a first light receiving medium aligned with said axis of said first lens structure to receive transmitted light rays for formation of an image thereon; c. a second light receiving medium angularly offset with respect to said axis of said first lens structure to receive transmitted light rays for formation of an image thereon; d. an apertured mirror arranged and positioned with respect to said front lens structure and said first and second light receiving mediums to pass light therethrough to said first medium to reflect light to said second medium, transmitting intensities of light to each of said mediums, for the intended purpose, without degradation or decrease of depth of field qualities for the respective images formed thereon; e. first and second rear lens structures arranged and positioned respectively between said apertured mirror and said light receiving mediums; and, f. light ray control means positioned between a selected one of said mediums and said apertured mirror to control light ray transmission to said medium.
Claim 2
Dependent Claim
217 words
A camera system for simultaneous and substantially total transfer of light rays from an object to separate, discrete mediums providing identical image reproduction at the mediums, said system including: a. a front lens structure arranged and constructed to receive light rays from the object and to direct the same axially thereof; b. a first light receiving medium aligned with said axis of said first lens structure to receive transmitted light rays for formation of an image thereon; c. a second light receiving medium angularly offset with respect to said axis of said first lens structure to receive transmitted light rays for formation of an image thereon; d. an apertured mirror arranged and positioned with respect to said front lens structure and said first and second light receiving mediums to pass light therethrough to said first medium to reflect light to said second medium, transmitting intensities of light to each of said mediums, for the intended purpose, without degradation or decrease of depth of field qualities for the respective images formed thereon; e. first and second rear lens structures arranged and positioned respectively between said apertured mirror and said light receiving mediums; and, f. light ray control means positioned between a selected one of said mediums and said apertured mirror to control light ray transmission to said medium.
Claim 3
Dependent Claim
30 words
The camera system as set forth in claim 1 and said apertured mirror being positioned at a 45 degree angle with respect to the axis of said front lens structure.
Claim 4
Dependent Claim
36 words
The camera system as set forth in claim 2 and said first and second light receiving mediums being arranged at right angles to one another and thereby at 45 degree angles with respect to said mirror.
Claim 5
Dependent Claim
26 words
The camera system as set forth in claim 1 and said aperture through said mirror constituting an ellipse whereby the apparent axial opening constitutes a circle.
Claim 6
Dependent Claim
29 words
The camera system as set forth in claim 1 wherein at least one of said light receiving mediums includes a film plane with means for positioning photographic film thereon.
Claim 7
Dependent Claim
34 words
The camera system as set forth in claim 5 wherein the other of said light receiving mediums provides an electronic video medium with means for simultaneous capturing of the image transmitted from the object.
