Abstract

A camera system for providing a split image field of view. The split image camera system utilizes two planar mirrors which are arranged along mutually intersecting planes so as to transmit images from different locations to the camera. The two mirrors are arranged such that their vertical axes are parallel while their horizontal axes intersect along the optical axis of the camera. By placing the reflective surfaces of the mirrors in a direction facing the camera, the camera is capable of viewing images from different locations and thus provides a split image view.

Claims

1. A split image camera system comprising:

a camera;

two planar members, each having a reflective coating on one of its planar surfaces; and

means for mounting both of said planar members such that the horizontal axes of said planar members intersect and the vertical axes of said planar members are substantially parallel with each other, wherein said planar members are mounted on said mounting means such that their reflective surfaces are facing the camera with which the mirror system is utilized and said planar members having their adjacent side edges closest to the camera and said side edges being separated by a sufficient distance so that a portion of the optical path of said camera is capable of obtaining a view from in between said planar members.

2. A system as defined in claim 1 wherein said planes of said planar members are arranged such that the view reflected by said reflective surfaces of said planar members to said camera only covers a portion of the optical view of said camera.

3. A system as defined in claim 1 wherein said planes of said planar members are arranged such that the view reflected by said reflective surfaces of said planar members to said camera only covers a portion of the optical view of said camera.

4. A system as defined in claim 1 wherein said camera is a video camera.

5. A split image camera system comprising:

a camera;

two planar members, each having a reflective coating on one of its planar surfaces;

means for mounting both of said planar members such that the horizontal axes of said planar members intersect and the vertical axes of said planar members are substantially parallel with each other, wherein said planar members are mounted on said mounting means such that their reflective surfaces are facing the camera with which the mirror system is utilized; and

further means for mounting said camera, said further mounting means for said camera being coupled to said mounting means for said planar members and said camera being adjustably mounted on said further mounting means such that said camera can be moved in a direction along its optical path relative to said planar members.
