ABSTRACT:
An image stabilization system for telescopic devices uses a method of selecting a suitable, stationary reference image. The user of the instrument views a circular image and a translucent ring concentric to and at an outer edge within the circular image. A translucent circle is superimposed within the width of the concentric ring so as to be able to move along the concentric ring to obtain a reference image. In order to select the reference image, the translucent circle travels, by viewer command, around the concentric ring until a suitable stationary image is observed within the translucent circle. Translation of the reference image within the concentric ring may be reactivated on command as many times as required to get an optimally stationary reference image. Image matching algorithms are then used to determine if the viewing area has moved by keying on and matching the vector movement of the reference image. This image stabilization system is particularly suited to hand-held binoculars or similar equipment. It permits the use of hand-held binoculars at very high magnification.
