Abstract
Abstract Disclosed herein is camera mounting apparatus which is particularly useful for independently adjusting the interocular spacing and convergence distance between the respective optical axes of a pair of cameras used in three-dimensional (3-D) photography. Such apparatus comprises a pair of slider mechanisms, each including a slider member which is connected to a camera housing (e.g., via a camera support plate) and movable along a rectilinear path defined by its respective mechanism. One of the slider mechanisms is mounted for pivotal movement about an axis which perpendicularly intersects the respective paths of both slider members. Separate means are provided for (a) adjusting the positions of the slider members along their respective sliding paths, and (b) adjusting the angular relationship of one sliding path relative to the other, whereby the camera support plate is movable through a predetermined interocular spacing (e.g. 4.5 inches) along a segment of a path having a radius of curvature which is adjustable through a desired convergence range (e.g. between 3 feet and infinity).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
208 words
In a 3-D photographic apparatus of the type comprising a pair of cameras, each having an objective lens for focusing light from a scene onto an image plane, camera mounting means for adjusting the position of one of said cameras relative to the other to independently vary (i) the effective interocular spacing and (ii) the convergence distance between the optical axes of said lenses, said adjusting means comprising: (a) a pair of slide mechanisms, each comprising a slider member and guide means defining a rectilinear slide path for said slider member, said guide means being arranged such that the slide paths defined thereby intersect a common axis extending perpendicular to said paths; (b) means of coupling said slide members to said one camera; (c) means for mounting one of said guide means for pivotal movement about said common axis; (d) means for adjusting the pivotal position of said one guide means about said common axis to adjust the angular relationship between said slide path from one in which said slide paths are parallel, to one in which said paths are angularly disposed; and (e) means for adjusting the positions of said slider members along their respective slide paths through a distance equal to a maximum desired interocular spacing.
Claim 2
Dependent Claim
208 words
In a 3-D photographic apparatus of the type comprising a pair of cameras, each having an objective lens for focusing light from a scene onto an image plane, camera mounting means for adjusting the position of one of said cameras relative to the other to independently vary (i) the effective interocular spacing and (ii) the convergence distance between the optical axes of said lenses, said adjusting means comprising: (a) a pair of slide mechanisms, each comprising a slider member and guide means defining a rectilinear slide path for said slider member, said guide means being arranged such that the slide paths defined thereby intersect a common axis extending perpendicular to said paths; (b) means of coupling said slide members to said one camera; (c) means for mounting one of said guide means for pivotal movement about said common axis; (d) means for adjusting the pivotal position of said one guide means about said common axis to adjust the angular relationship between said slide path from one in which said slide paths are parallel, to one in which said paths are angularly disposed; and (e) means for adjusting the positions of said slider members along their respective slide paths through a distance equal to a maximum desired interocular spacing.
Claim 3
Dependent Claim
43 words
The apparatus as defined by claim 1 wherein said coupling means comprises a pair of pivot posts, one being supported by each of said slider members, a camera support plate, and means for pivotally connecting said plate to each of said pivot posts.
Claim 4
Dependent Claim
53 words
The apparatus as defined by claim 2 wherein said support plate is arranged relative to said slider members such that when the interocular spacing between said camera is zero, said common axis substantially coincides with the axis of the pivot post supported by that slider member guided by said pivotally mounted guide means.
Claim 5
Dependent Claim
38 words
The apparatus as defined by claim 3 wherein said one camera is arranged on said support plate such that the nodal point of the camera's lens is located on a line connecting the center of said pivot posts.
Claim 6
Dependent Claim
32 words
The apparatus as defined by claim 4 wherein said nodal point is displaced from the pivot post of the other of said guide means by approximately one-half the maximum desired interocular spacing.
Claim 7
Dependent Claim
133 words
Camera mounting apparatus comprising: (a) a pair of slide mechanisms, each comprising a slider member and guide means defining a rectilinear slide path for said slider member, said guide means being arranged such that the slide paths defined thereby intersect a common axis extending perpendicular to said paths; (b) means of coupling said slide members to a camera; (c) means for mounting one of said guide means for pivotal movement about said common axis; (d) means for adjusting the pivotal position of said one guide means about said common axis to adjust the angular relationship between said slide path from one in which said slide paths are parallel, to one in which said paths are angularly disposed; and (e) means for adjusting the positions of said slider members along their respective slide paths.
Claim 8
Dependent Claim
133 words
Camera mounting apparatus comprising: (a) a pair of slide mechanisms, each comprising a slider member and guide means defining a rectilinear slide path for said slider member, said guide means being arranged such that the slide paths defined thereby intersect a common axis extending perpendicular to said paths; (b) means of coupling said slide members to a camera; (c) means for mounting one of said guide means for pivotal movement about said common axis; (d) means for adjusting the pivotal position of said one guide means about said common axis to adjust the angular relationship between said slide path from one in which said slide paths are parallel, to one in which said paths are angularly disposed; and (e) means for adjusting the positions of said slider members along their respective slide paths.
Claim 9
Dependent Claim
43 words
The apparatus as defined by claim 6 wherein said coupling means comprises a pair of pivot posts, one being supported by each of said slider members, a camera support plate, and means for pivotally connecting said plate to each of said pivot posts.
