Vorrichtung zur digitalen Bildstabilisierung durch Objektverfolgung und Verfahren dafür

摘要

An apparatus for digital image stabilization using object tracking includes an image signal processing unit for outputting a first digital image data obtained under a first exposure value condition and a plurality of second digital image data obtained under a second exposure value condition. The apparatus also includes a shaky hand compensating unit for compensating for motion of comparative second digital images relative to a reference second digital image by tracking an object in either the binary or the reverse binary images of the plurality of second digital images that have more objects. The compensating unit then generates a shaky hand compensated image by overlapping the motion-compensated images with the reference image. The apparatus further includes an image property correcting unit for correcting a property of the shaky hand compensated image based on the property of the first digital image.
