First Claim
Patent Images
1. A viewing apparatus having a composite field of view, comprising:
- at least two image transducers, each having an individual field of view;
a reflective element having at least one reflective area that is positioned to redirect at least part of the field of view associated with a first one of the image transducers;
at least part of the redirected field of view being merged with at least part of the field of view associated with the second one of the image transducers to produce the composite field of view of the viewing apparatus, these parts of the fields of view associated with the first and second image transducers being arranged with respect to the reflective area to create a blind region that is not in either of these two parts of the fields of view, that encompasses a portion of an edge of the reflective area, and that is located between the parts of the two fields of view associated with the first and second image transducers that produce the composite field of view.

Abstract
Cameras are positioned so that they each view a different reflective surface of a polyhedron such as a pyramid. This results in each camera having a virtual optical center positioned within the pyramid. The cameras are positioned so that their virtual optical centers are offset from each other. The offsets produce narrow blind regions that remove image distortions received from the edges of the pyramid'"'"'s reflective surfaces. Additionally, planar shades that extend in an outward direction are positioned in the blind regions.
