An approach of electronic image stabilization is presented for the E-O imaging system of airborne platform to restore the video image degraded by both intraframe motion-blurred and interframe vibration. The 2D motion-blurred point spread function (PSF)is set up by a motion-blurred mathematical model

then Wiener filter is used to restore the intraframe motion-blurred video images. A gray projection algorithm is presented to estimate the motion vector between the current frame and the reference frame in video image sequence

which is used to compensate video image sequence to make the video image sequence output stable. The experiment results show that the proposed approach has feasible

quick and accurate characteristics

which can improve the peak signal noise ratio(PSNR) effectively and reach the accuracy of 1 pixel

also can improve imaging quality and ensure video image sequence output clearly and stably.
