Abstract

A method and apparatus for presenting a scene generated by an electronic visual scene generator to an observer looking through a pair of binoculars 32 is disclosed. The scene presented by the binoculars is an enlarged or magnified portion of a panoramic scene presented on a screen 12 also generated by the visual scene generator 28 and suitable for viewing by the observers unaided eye. In the described embodiment, electronic signals representative of a scene are generated by digital generator 28. These electrical signals are then applied to three small CRT'"'"'s 72, 74 and 70 each of which has a different color such as red, green and blue where the visual scene is produced by the CRT'"'"'s three colors. The three CRT'"'"'s colored images are then combined by means of beam splitters, filters and mirrors 44 to provide a single full colored scene which is then transported to both eye pieces of a pair of hand held binoculars 32 or to the eye piece of a periscope 48 by means of a fiber optic cable 36 and 50 respectively. A panoramic scene on screen 12 and suitable for viewing by the unaided eye and generated by the digital generator 28 is also provided by suitable means such as a CRT projector 14. Thus, by monitoring the orientation of the binoculars 32 a magnified or enlarged view (such as 8×) of a portion of the panoramic view can be provided by the binoculars, for example, according to the orientation. Thus, in accordance with the embodiment described the observer or tank commander can closely inspect by means of the binoculars a selected portion of the panoramic scene as would be the case in a real life situation.

Claims

1. Apparatus for providing selected visual scenes to an observer comprising:

a first eye piece and a further eye piece for viewing said selected visual scenes by said observer, said first eye piece and said further eye piece being suitable for orienting in a selected direction;

source means for generating electric signals representative of said selected visual scenes;

display means for receiving and converting said electrical signals into a visual representation of said selected visual scenes;

optical transporting means for receiving said visual representation from said display means and transporting said visual representation to said first eye piece and to said further eye piece for viewing by said observer; and

means for connecting said transporting means and said first eye piece and said further eye piece to provide said selected visual scenes to both said first and further eye pieces.

2. The apparatus of claim 1 wherein said selected visual scene is generated in response to a selected control signal and further comprising means for detecting the orientation of said first eye piece and for providing a first control signal which is representative of said orientation of said first eye piece and suitable for use as said selected control signal.

3. The apparatus of claim 1 wherein said source means comprises means for digitally generating said selected visual scenes.

4. The apparatus of claim 1 wherein said first eye piece and further eye piece are the eye pieces of hand held binoculars.

5. The apparatus of claim 1, 2, 3 or 4 wherein said display means further comprises three CRT'"'"'s, each of said CRT'"'"'s producing said visual representation in three different colors and means for combining said three different color visual representations such that said visual representation optically transported to said eye piece represents a full color scene.

6. The apparatus of claim 2 and further comprising;

another eye piece for viewing said selected visual scene by said observer, said another eye piece also suitable for orientation in a selected direction;

another optical transporting means for receiving said visual representation from said display means and transporting said visual representation to said another eye piece for viewing by said observer;

means for determining the orientation of said another eye piece and for providing another control signal representative of said orientation of said another eye piece and suitable for use as said selected control signal;

means for determining which of said first and another eye piece is being viewed by said observer; and

means for selecting that one of said first and another control signals for use as said selected control signal corresponding to said eye piece being viewed by said observer.

7. The apparatus of claim 6 wherein said first eye piece comprises a part of hand held simulated binoculars, and said another eye piece comprises a part of a simulated periscope.

8. The apparatus of claim 6 or 7 and further including means for providing a selected panoramic visual scene also generated by said source means and suitable for viewing without the aid of an eye piece, and wherein said selected visual scene is an enlarged portion of said panoramic visual scene.

9. Apparatus for providing selected scenes to an observer comprising:

first and further eye pieces for viewing said selected scenes by said observer, said first and further eye pieces comprising the eye pieces of hand held binoculars suitable for orientation in a selected direction;

source means for digitally generating electrical signals represents of said selected scenes, the selection of one of said selected scenes being generated in response to a control signal;

three CRT means for receiving and converting said electrical signals into a visual representation of said selected scenes, each of said three CRT'"'"'s producing said selected visual scenes in three different and distinct colors;

means for combining said three distinctly colored visual scenes from said three CRT'"'"'s such that a single visual scene representing a full color scene is produced;

optically transporting means for receiving said full color representation from said three CRT'"'"'s, and transporting said full color visual representation to said first and further eye pieces of said hand held binoculars for viewing by said observer; and

means for determining the orientation of said first and further eye pieces of said hand held binoculars and for providing said control signal which is representative of said orientation and binoculars.

10. A method for providing selected visual scenes to an observer comprising the steps of:

viewing said selected visual scenes through a first eye piece and a further eye piece by orientating said first and further eye pieces in a selected direction;

digitally generating said visual scenes and providing electrical signals representative of said selected visual scenes;

receiving and converting said electrical signals into a visual representation of said selected visual scenes for displaying on a display means; and

optically transporting said visual representation from said display means to said first eye piece and to said further eye piece for viewing by said observer.

11. The method of claim 10 wherein said step of digitally generating is in response to a selected control signal, and further comprising the steps of detecting the orientation of said first and further eye pieces and providing a first selected control signal which is representative of said orientation and which is suitable for use as said selected control signal.

12. The method of claim 10 or 11 wherein said displaying comprises the step of producing said visual representation in three distinct colors on three CRT'"'"'s and further comprising the step of combining said three distinct color visual representation such that said visual representation optically transported to said eye piece represents a full color scene.
