1. A video camera, comprising:

  • first integration vector calculating means for calculating an integration vector Sn according to the following equation (1) on the basis of a whole motion vector Vn, where
    
    
    space="preserve" listing-type="equation">S.sub.n =K.sub.1 ·

    S.sub.n-1 +V.sub.n (

         1)Sn ;

    an integration vector of n-th field or frameSn- 1;

    an integration vector of (n-1)th field or frameVn ;

    a whole motion vector between the (n-1)th field or frame and the n-th field or frameK1 ;

    an attenuation coefficient less than 1;

    second integration vector calculating means for calculating an integration vector Sn of the image according to the following equation (2) on the basis of the whole motion vector Vn, where
    
    
    space="preserve" listing-type="equation">S.sub.n =S.sub.n-1 -K.sub.2 ·

    |V.sub.n |(2)K2 ;

    an attenuation coefficient less than 1; and

    correction means for correcting a blurring of an image according to the integration vector calculated by one of said first integration vector calculating means and said second integration vector calculating means.
