Abstract
A camera having blurring movement correction mechanism comprising: an optical element arranged to correct shift of an image formed on a film surface caused by movement of hands holding a camera body; an actuator for moving the optical element in a necessary direction for correcting the image shift; a detection unit for obtaining a blurring movement detection data by converting the movement of the camera body to an electric signal; a first memory unit for temporarily registering the detection data output from the detection unit; a calculation unit for calculating blurring movement correction data for correcting the image shift caused by movement of the camera body by actuating the optical element by the actuator; and a second memory unit for temporarily registering data of calculation. The correction data is predictively calculated from the detection data of this time obtained from the detection unit, the detection data of the preceding time registered in the first memory unit and the correction data of the preceding time registered in the second memory unit.
