Abstract
Taking a satisfactory image using a hand-held camera under dim lighting conditions is difficult because there is a tradeoff between exposure time and motion blur. If the image is taken with a short exposure time, the image is noisy, although it preserves sharp details. On the other hand, an image taken with a long exposure time suffers from motion blur but has good intensity. In this paper, we propose a two-image approach that adaptively combines a short-exposure image and a long-exposure image for the image stabilization function on digital cameras. Our method combines only the desirable properties of the two images to obtain a less-blurry and less-noisy image. Furthermore, the proposed approach uses a dual edge-preserving filtering technique for the edge areas of the long-exposure image, which are more affected by motion blur.
