ABSTRACT:
A camera having a blurring movement correction mechanism comprising: an 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. The camera further comprises: a detection unit for obtaining a blurring movement detection data by converting the blurring movement of the camera body to an electric signal; a calculation circuit for calculating blurring movement correction data for correcting the shift of the image formed on the film surface caused by movement of hands holding the camera body; a blurring movement correction actuator for moving the optical element in a necessary direction for correcting the shift of the image on the film surface on the basis of the blurring movement correction data obtained from the calculation circuit; and a noise removing circuit for removing transition output components included in the blurring movement detection data obtained from the detection unit which components are generated at a time when said blurring movement correction actuator is driven.
