Abstract
The invention provides a digital image stabilization apparatus for compensating a jitter occurred in the ith frame among N frames of a video sequence, where each of the N frames includes a plurality of blocks, N is a natural number larger than or equal to 3 and i is an integer index ranging from 1 to N. The apparatus includes a determining module, a comparing module and an adjusting module. The determining module is to determine a block of background region BRi-in the (i−1)th frame. The comparing module, coupled to the determining module, is to compare the block of BRi-in the (i−1)th frame with the corresponding block in the ith frame so as to determine a jitter vector. The adjusting module, coupled to the comparing module, is to adjust the ith frame in accordance with the jitter vector to compensate for the jitter occurred in the ith frame.
