<p>PURPOSE:To prevent a photograph from being blurred by efficiently and quickly calculating a camera-shake and instantly negating the camera-shake, even if it occurs. CONSTITUTION:The camera-shake occurring at the time of photographing is detected by a camera-shake sensor 6 and the signal of the detection is sampled in a sampling circuit 10, to be stored in a storage circuit 11 and simultaneously Fourier-transformed by a processor 26. A sampling time at this time can be varied so that in the camera-shake sensor 6, more optimum camera-shake detection data can be obtained in accordance with a difference in an intrinsic characteristic and the level of the variable component of the output data of the camera-shake detection data by an arithmetic circuit 27, a comparing circuit 28 and a sampling time calculating circuit 29. The output of the storage circuit 11 is converted into camera-shaking speed data and camera-shaking quantity data by the camera-shake calculating circuit 31 and a camera-shake correction data conversion circuit 32, so that a camera-shake correction actuator 9 drives a correcting optical member 5 so as to negate the movement of the position of an image caused by the camera-shake on a film surface 2, by the reception of the data.</p> |
