APPARATUS AND METHOD FOR DIGITAL IMAGE STABILIZATION USING OBJECT TRACKING
First Claim
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 tocompensate for motion in a plurality of comparative second digital images relative to a reference second digital image using object tracking, andgenerate a compensated image by overlapping each compensated comparative image with the reference image; and
an image property correcting unit operative to correct a property of the compensated image based on a property of the first digital image.

Abstract
Apparatus for digital image stabilization using object tracking can produce a digital still image free of an image blurring phenomenon caused by shaky hands without separate hardware and can produce an image that is bright, clear, and noise free. The apparatus 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 using object tracking. The compensating unit then generates a shaky hand compensated image by overlapping each compensated comparative image 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.
