Abstract

Abstract A superimposing image apparatus for superimposing a first view on a second view, including an optical imaging system which has a given focal length, an image plane and given field of view which encompasses the second view, and an arrangement for translationally moving a first mirror within the aforesaid field of view and positioned so as to project at least a part of the first view into the lens system, superimposed on the second view. In accordance with a second feature, there is provided a superimposed image apparatus wherein at least one of the first and second views is disposed at the given focal length of the lens system. In accordance with still another feature, there is provided superimposing image apparatus which includes a second mirror disposed outside the field of view for reflecting the first view onto the first mirror. In accordance with yet another feature, there is provided a superimposing image apparatus wherein the translation apparatus for translationally supporting the first mirror has at least one linear axis of translation. The invention may further include apparatus wherein the translation apparatus has a sheet of transparent material for mounting the first mirror, wherein the sheet of transparent material is attached to the apparatus for translationally moving the first mirror, and the invention may optionally include apparatus wherein the first mirror is partially transparent and/or tinted.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 87 words
A superimposing image apparatus for superimposing at least one first view on a second view, comprising optic means having a given focal length and an image plane for receiving said first and second views, at least one first mirror for reflecting said first view onto said image plane, wherein said first and second views are disposed at distances from said optic means equal to said given focal length, and said first mirror is disposed at a distance from said optic means different from said given focal length.
Claim 2
Dependent Claim 87 words
A superimposing image apparatus for superimposing at least one first view on a second view, comprising optic means having a given focal length and an image plane for receiving said first and second views, at least one first mirror for reflecting said first view onto said image plane, wherein said first and second views are disposed at distances from said optic means equal to said given focal length, and said first mirror is disposed at a distance from said optic means different from said given focal length.
Claim 3
Dependent Claim 32 words
Superimposing image apparatus according to claim 1, wherein said first and second views are disposed in respective first and second planes, and wherein said image plane is parallel with said second plane.
Claim 4
Dependent Claim 20 words
Superimposing image apparatus according to claim 1, including a second mirror for reflecting said first view onto said first mirror.
Claim 5
Dependent Claim 25 words
Superimposing image apparatus according to claim 1, including translation means for translationally moving said first mirror in an x-y plane parallel with said image plane.
Claim 6
Dependent Claim 30 words
Apparatus according to claim 4, including a sheet of transparent material for supporting said first mirror, and connecting means for connecting said sheet of transparent material to said translation means.
Claim 7
Dependent Claim 40 words
Apparatus according to claim 5, wherein said translation means include a frame enclosing said sheet of transparent material, a set of y-bars slidably supporting said frame, and a set of x-bars perpendicular to said y-bars for slidably supporting said y-bars.
Claim 8
Dependent Claim 17 words
Apparatus according to claim 1 including a camera for containing said image plane and said optic means.
Claim 9
Dependent Claim 19 words
Apparatus according to claim 1, wherein said first mirror is rigidly connected with an object representing said first view.
Claim 10
Dependent Claim 45 words
Apparatus according to claim 1, wherein the distance between said first view and said first mirror is equal to f2, and the distance between said optic means and said first mirror is equal to f1, and f1+f2 is constantly equal to said given focal length.
Claim 11
Dependent Claim 22 words
Apparatus according to claim 3 wherein said second mirror is disposed at an angle substantially equal to 30° with said image plane.
