1. A method for capturing images, comprising: acquiring a plurality of preview images; estimating a global motion and a local motion based on at least a portion of the plurality of preview images; and if the local motion is less than or equal to the global motion, capturing a final image based at least on an exposure time based on the global motion; else capturing a first image based on at least a first exposure time, capturing at least a second image based on at least one second exposure time less than the first exposure time, separating each global motion region from each local motion region in the first and second images, and reconstructing the final image based at least on each local motion region.
