Area of interest display system with opto/mechanical image combining
First Claim
1. An area of interest display system wherein area of interest imagery of relative great detail and resolution is displayed in the spatial position of the foveal region of the eye of an observer and background imagery of relatively lesser detail and resolution is displayed about the area of interest imagery, comprising:
- first display means for projecting said area of interest imagery;
second display means for projecting said background imagery and defining an area to receive said area of interest imagery;
means for combining said area of interest imagery and said background imagery whereby said area of interest imagery is set in said area to receive said image; and
means for oscillating said image boundary for said area of interest imagery in relation to said background imagery.

Abstract
In an area of interest (AOI) display, a detailed image is projected on a screen at the area of interest while a background image is projected on the surrounding area such that the boarder between the two areas varies in an orbital oscillating pattern to accomplish visual blending. A combiner includes a transparent portion to accommodate projection of the background image at the area of interest. The opaque portion carries a mirror to reflect the detailed image filling the area of interest. The combiner is oscillated in an orbital pattern at a resonant frequency, e.g. 210 Hertz by a three phase electromechanical drive unit.

2. A graphics system for providing color image displays including a low resolution, wide field background and a contained high resolution, area of interest, said system comprising:
-
means for projecting at least one low resolution wide field, color component for an image display and defining an area of interest; means for projecting at least one high resolution color component for filling said area of interest in said image display; means for combining said low resolution wide field color component and said high resolution color component for said display; and means for imparting a relative oscillating motion between said color components. - View Dependent Claims (3, 4, 5, 6, 7, 8)
