<p>PURPOSE:To provide an image blur preventing device capable of highly precisely correcting the blur of an image caused by a vibration. CONSTITUTION:The shaking of a photographic optical system is detected by a camera-shake detecting means 9 and when the blur of the image caused by the photographic optical system is corrected from a camera-shake signal from the camera-shake detecting means 9 and a blur correction coefficient stored in a correction coefficient changing means 13 provided on a part of the photographic optical system by blur correcting means 11 and 13, they obtain the blur correction coefficient from the correction coefficient changing means 13 based on the focal distance information of the photographic optical system and the changing means 13 sets the initial value of the blur correction coefficient to the value when the photographic optical system is on a longest focal distance side.</p> |
