1. A camera having blurring movement correction mechanism comprising:

  • a blurring movement correction optical element disposed in an optical path of a photo-taking optical system so as to correct shift of an image formed on a film surface caused by movement of hands holding a camera body;

    a blurring movement correction actuator for moving said optical element in a necessary direction for correcting said shift of the image on the film surface;

    a blurring movement detection unit for obtaining a blurring movement detection data by converting said blurring movement of said camera body to an electric signal;

    a first memory means for temporarily registering said detection data output from said detection unit;

    a calculation means for calculating blurring movement correction data for correcting said shift of the image formed on the film surface caused by movement of hands holding the camera body by actuating said optical element by said actuator; and

    a second memory means for temporarily registering an output data of calculation from said calculation means,said calculation means being so constructed that said blurring movement correction data is predictively calculated on the basis of said detection data of this time obtained from said detection unit, said detection data of the preceding time registered in said first memory means and said correction data of the preceding time registered in said second memory means so as to correct said shift of the image formed on the film surface by actuating said optical element by said actuator.
