An image stabilization system and method. The inventive system ( ) includes an image sampling circuit ( ) mounted on a platform ( ) for sampling an image in response to timing control signals and outputting a plurality of imaging signals in response thereto. An azimuth resolver ( ) detects vibration of the platform and providing a signal in response thereto. A microprocessor ( ) adjusts the timing control signals to cause the image sampling circuit ( ) to sample the image and thereby compensate for an effect of vibration on the image. In the illustrative embodiment, the microprocessor ( ) includes software for compensating for vibration that causes image offset, compressed images, expanded images, and compression and expansion within a single field. The invention provides image stabilization in a purely electronic manner without the need for any moving parts that would typically require control hardware and a significant amount of space. In addition, since LOS motion compensation takes place as the image is being sampled, this method eliminates the need for the large amounts of memory required to store a field of video as well as LOS information for post processing.
