Abstract
Abstract A composite photographic picture is generated through double-exposure, whereby the object, as for instance a person, is photographed on one half of the picture whereas a grid pattern is photographed on the other half; for the second exposure, person and grid pattern change position. In each instance of exposure, a line pattern is projected onto the object under utilization of one movable or two fixed, overhung projectors. Equipment is enclosed, permitting easy change of scenery.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
167 words
The method of acquiring image information of an object from different sides thereof, comprising the steps of placing the object in a first position and in a portion of a field of view of a camera; providing a grid pattern next to that object; projecting a line pattern onto the object; exposing on a film in the camera an image of the object with projected line patterns and next to it an image of the grid pattern; exchanging positions of the grid pattern end of the object, the object being oriented at a different angle in relation to the angle of the camera in the exchanged position as compared with the relative position between the camera and the object when the object is exposed as per the exposing step; projecting a line pattern onto the object in the exchanged position; and exposing the same film strip in the camera to an image of the object with projected line patterns and the grid pattern in the exchanged position.
Claim 2
Independent Claim
167 words
The method of acquiring image information of an object from different sides thereof, comprising the steps of placing the object in a first position and in a portion of a field of view of a camera; providing a grid pattern next to that object; projecting a line pattern onto the object; exposing on a film in the camera an image of the object with projected line patterns and next to it an image of the grid pattern; exchanging positions of the grid pattern end of the object, the object being oriented at a different angle in relation to the angle of the camera in the exchanged position as compared with the relative position between the camera and the object when the object is exposed as per the exposing step; projecting a line pattern onto the object in the exchanged position; and exposing the same film strip in the camera to an image of the object with projected line patterns and the grid pattern in the exchanged position.
Claim 3
Dependent Claim
19 words
A method as in claim 1, the projected line pattern or patterns being composed of or including horizontal lines.
Claim 4
Dependent Claim
17 words
A method as in claim 1, the line pattern being flash-projected in synchronization with the camera's exposure.
Claim 5
Dependent Claim
24 words
A method as in claim 1, the line pattern or patterns being projected at an angle of between 30° to 60° to the vertical.
Claim 6
Dependent Claim
19 words
A method as in claim 2, the line pattern or patterns as projected being composed of equidistantly spaced lines.
Claim 7
Dependent Claim
31 words
A method as in claim 1, wherein the object is placed in such a way that the line pattern is focused onto a surface portion of the object facing the camera.
Claim 8
Independent Claim
94 words
An apparatus of the characteristics described, comprising: a photographic camera directed toward a particular field of view; a stage means in the field of view; a vertical partition centrally disposed on the stage means and having a front edge; a plate hinged to said edge and carrying a grid pattern on both sides of the plate provided for covering one half or the other half of the stage means; and projection means for projecting a line pattern into the other half or the one half of the stage means not covered by the plate.
Claim 9
Independent Claim
94 words
An apparatus of the characteristics described, comprising: a photographic camera directed toward a particular field of view; a stage means in the field of view; a vertical partition centrally disposed on the stage means and having a front edge; a plate hinged to said edge and carrying a grid pattern on both sides of the plate provided for covering one half or the other half of the stage means; and projection means for projecting a line pattern into the other half or the one half of the stage means not covered by the plate.
Claim 10
Dependent Claim
25 words
An apparatus as in claim 7, the projection means including at least one projector having an axis of the projector, being inclined in downward direction.
Claim 11
Dependent Claim
16 words
An apparatus as in claim 7 or 8, the projection means including two fixed, mounted projectors.
Claim 12
Dependent Claim
34 words
An apparatus as in claim 8, the projection means including a single projector and means for positioning the single projector in front of the one half or the other half of the stage means.
Claim 13
Dependent Claim
25 words
An apparatus as in claim 10, the means for positioning including overhung rail means, the projection being movably disposed for running in the rail means.
Claim 14
Dependent Claim
28 words
An apparatus as in claim 10, including means for coupling the plate to the projector so that, upon pivoting the plate as hinged, the projector is repositioned therewith.
Claim 15
Dependent Claim
33 words
An apparatus as in claim 8, the projector having a corrected lens system which includes a lens closest to a light source of the projector, having its axis inclined to the projector axis.
