Abstract
This specification discloses an image movement correcting device for a photographing apparatus for appropriately judging a variation in the amount of image movement correction by the difference in the position of the center of rotation, and effecting accurate image movement correction. Any angular fluctuation of the optical axis of the photographing apparatus is detected by angular displacement detecting device, and when on the basis of the angular fluctuation, image movement correction on a photographing image field is effected by image movement correcting device, the amount of image movement correction by the image movement correcting device is varied in conformity with the position of the center of rotation discriminated by rotation center position discriminating device for discriminating the position of the center of rotation of the angular fluctuation during the photographing by the photographing apparatus.
