ABSTRACT:
System for producing a stabilized image of a scene viewed by an image detector, the image detector detecting a plurality of images of the scene, the image detector being supported by gimbals, the gimbals including a servo system for moving the gimbals at least one degree of freedom, the system including an angular movement detection device firmly coupled with the image detector, and a processor coupled with the angular movement detection device and with the image detector, the angular movement detection device detecting at least a portion of angular movements of the image detector about at least one axis of rotation, the angular movement detection device producing an angular output respective of the portion, the processor receiving the images from the image detector, and the angular output from the angular movement detection device, the processor determining at least one shifting displacement and at least one shifting direction for shifting a current image detected by the image detector, relative to a reference image of the scene detected by the image detector, according to the angular output, the processor producing the stabilized image, by shifting the current image by the shifting displacement and in the shifting direction.
