Abstract
Abstract Method of, and apparatus for, enhancing and detecting a small static object in a scene. The object perceptability against the surrounding scene is enchanced by moving a static image of the scene in a preselected programmed motion. The motion blurs the undesired clutter of the scene; and, the small static object is detected by and because of the trace made by the movement of the image of the small static object.

Claim 1
Independent Claim
174 words
Apparatus for enhancing and detecting the image of a small static object in the image of a scene which includes the object, wherein said object is detectable by and because of its trace when the image of said object is moved, comprising: a. means for acquiring a static image of the scene and of the small static object therein; b. means for displaying the acquired static image of the scene and of the small static object therein, with said means linked to said image acquiring means; c. means for imparting a preselected programmed motion to the displayed static image of the scene, with said preselected programmed motion describing a predetermined locus, and with said means linked to said image displaying means. d. and, means for viewing the resultant moving image of the static scene, with said means linked to said motion imparting means; whereby the image of the small static object is enhanced and is detected by and because of the trace made by the movement of the image of the small static object.
