ABSTRACT:
A high resolution imaging system having a wide field-of-regard. The wide field image generation system (10) of the present invention is operative to provide a composite digital representation of a scene within a field-of-regard. The invention (10) includes a sensor arrangement (12, 14, and 16) for generating first and second frames of image data. A scene correlator (18) registers the first and second frames of image data within the field-of-regard. A temporal filter (22) averages image data in the first frame with image data at a respective corresponding location in the second frame to provide a third frame of image data. When displayed, the third frame of image data provides a wide field-of-regard, high resolution image with minimal undesirable seams therein.
