    摘要: Deblurring digital camera images captured in low-light, long-integration-time conditions by capturing multiple short-integration images and fusing with on-the-fly motion estimation and alignment to limit the frame memory requirements. In one embodiment, an image stabilization system includes: (1) a frame memory and (2) a processor coupled to the frame memory and configured to store a first short-integration digital image in the frame memory, determine a displacement of a second short-integration digital image relative to the first short-integration digital image, combine the second short-integration digital image with the first short-integration digital image to form a fused digital image and overwrite the first short-integration digital image with the fused digital image.
