Abstract:
1. An apparatus for digital image stabilization comprising: an image signal processing unit operative to output 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; a compensating unit operative to: generate a shaky hand compensated image by overlapping the motion-compensated images with the reference image; and an object labeling unit operative to: track an object in an image among binary images and reverse binary images of the reference image and each comparative image, and label the object; a motion value computing unit operative to: match an object parameter of each comparative image with an object of the reference image, calculate an object parameter of each comparative image, and compute a motion value for each comparative image using the calculated object parameter; a motion compensating unit operative to apply each computed motion value to a corresponding comparative image to compensate for motion of each comparative image; and a compensated image generating unit operative to overlap each motion-compensated comparative image with the reference image to generate a shaky hand compensated image.
