Abstract
Abstract Apparatus for photographing stationary objects such as paintings comprises a mobile camera structure in which is located a principal objective lens for forming an image of the object to be photographed and an image receiving means such as film, and a stationary housing having an auxiliary objective lens for forming an image of a stationary reference object which is subject to the same illumination as the principal object. The fixed position housing containing the auxiliary objective lens is located spatially from the mobile camera structure and is coupled to the latter by means of a flexible light conductor which thus provides mobility for the camera and carries the image formed by the auxiliary objective lens into the camera for imaging on the film adjacent the image of the principal object. Either a single shutter or two separate synchronized shutters are used to expose a film in the image plane of the principal objective lens to the images formed by the principal and auxiliary objective lenses. Instead of a flexible light conductor the mobile camera structure and stationary housing for the auxiliary objective lines can be coupled by a flexible electric cable which transmits signals from photoelectric cells in the auxiliary objective lens housing and mounted behind the auxiliary objective lens to lamps mounted in the camera structure above the image plane of the principal objective lens.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
147 words
Apparatus for photographing a stationary principal object together with a stationary reference object illuminated from the same source of light comprising a mobile camera including therein a principal objective lens for forming an image of the principal object on an image receiving means such as film within said camera, an auxiliary objective lens arranged within a stationary housing spatially separated from said mobile camera and which occupies a fixed position relative to said reference object for forming an image of the latter, flexible transmission means extending between said housing and said camera for transmitting the image of the reference object formed by said auxiliary objective lens into said mobile camera and onto said image receiving means adjacent the image of the principal object, and shutter means for controlling the passage of the images formed respectively by said principal and auxiliary objective lens to said image receiving means.
Claim 2
Dependent Claim
147 words
Apparatus for photographing a stationary principal object together with a stationary reference object illuminated from the same source of light comprising a mobile camera including therein a principal objective lens for forming an image of the principal object on an image receiving means such as film within said camera, an auxiliary objective lens arranged within a stationary housing spatially separated from said mobile camera and which occupies a fixed position relative to said reference object for forming an image of the latter, flexible transmission means extending between said housing and said camera for transmitting the image of the reference object formed by said auxiliary objective lens into said mobile camera and onto said image receiving means adjacent the image of the principal object, and shutter means for controlling the passage of the images formed respectively by said principal and auxiliary objective lens to said image receiving means.
Claim 3
Dependent Claim
75 words
Photographic apparatus as defined in claim 1 wherein said transmission means for the image of the reference object formed by said auxiliary objective lens is constituted by a flexible light conductor and wherein said shutter means controlling the passage of the image formed by said auxiliary objective lens to said image receiving means is constituted by a shutter located on said camera and which functions to control the passage of light through said light conductor.
Claim 4
Dependent Claim
69 words
Photographic apparatus as defined in claim 1 wherein said transmission means for the image of the reference object formed by said auxiliary objective lens is constituted by a flexible light conductor and wherein said shutter means comprises a focal plane shutter mounted adjacent said image receiving means and which is operable to expose both the image of the principal object and the reference object to said image receiving means.
Claim 5
Dependent Claim
84 words
Photographic apparatus as defined in claim 1 wherein said transmission means for the image of the reference object formed by said auxiliary objective lens includes photosensitive means mounted within said housing and to which the image of the reference object is transferred from said auxiliary objective lens, a light source within said camera, and a flexible electrical connection extending between said photosensitive means and said light source for controlling the intensity thereof in accordance with the magnitude of the response of said photosensitive means.
Claim 6
Dependent Claim
90 words
Photographic apparatus as defined in claim 4 wherein said photosensitive means comprises a plurality of photoelectric cells and a corresponding plurality of different colored filters mounted between said photoelectric cells and said auxiliary objective lens, and said light source comprises a plurality of lamps and a corresponding plurality of filters each having the same color as a different one of the filters comprising said photosensitive means, said electrical connection including amplifiers and flexible electrical conductor means connecting each one of said photoelectric cells to a different one of said lamps.
Claim 7
Dependent Claim
30 words
Photographic apparatus as defined in claim 5 including a light-tight box housing said plurality of lamps, and a ground glass screen mounted between said lamps and said image receiving means.
Claim 8
Dependent Claim
54 words
Photographic apparatus as defined in claim 4 wherein said shutter means includes means for interrupting the electrical connection between said photosensitive means and said light source for a predetermined period of time, and a shutter for passing the image of the principal object formed by said principal objective lens to said image receiving means.
Claim 9
Dependent Claim
37 words
Photographic apparatus as defined in claim 1 wherein said principal objective lens and said transmission means are mounted within said camera such that one edge of the respective images of the principal and reference objects are aligned.
