Abstract
Apparatus for digital image stabilization using object tracking includes an image signal processing unit that outputs a first digital image obtained under a first exposure value condition and a plurality of second digital images obtained under a second exposure value condition. The apparatus also includes a shaky hand compensating unit that compensates for motion in comparative second digital images relative to a reference second digital image by tracking an object in either a binary image or a reverse binary image of a respective second digital image that has the most objects (i.e., in the binary or reverse image). 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 that corrects a property of the shaky hand compensated image based on a property of the first digital image.
