A camera is provided with an image blur reducing function and rotation
means. The image blur reducing function is turned off during rotation in
a constant-speed drive pattern in which the rotation means rotates the
camera at a constant speed from a start to an end of the rotation
operation. The image blur reducing function is turned on during rotation
in an intermittent drive pattern in which the rotation means
intermittently executes drive operation from the start to the end of the
rotation operation.
