Abstract:
1. A digital image stabilization method that integrates a digital video encoder and a digital stabilization device together to form an integrated system, said method calculating motion vectors of an image sequence, said method comprising the steps of: (a) a comparison module in said digital video encoder comparing one I frame and one P frame or one P frame and another P frame to generate a first motion vector based on the compared image frames; (b) a determination module using said first motion vector to define a background region of said P frame; (c) calculating a second motion vector of at least one B frame before or after said P frame for said background region based on the compared image frames, and using said second motion vector to adjust said jerky B frame; and (d) repeating Steps (b) and (c) to calculate said background regions of a plurality of subsequent P frames and B frames; wherein each of said subsequent P frames uses a background region of the preceding P frame as the background region thereof.
