Abstract
There is disclosed an image blur prevention apparatus which has a first means for sampling a first signal associated with image blur prevention, and a second means for performing an operation for forming a second signal used in image blur prevention of the image blur prevention apparatus on the basis of the signal sampled by the first means, at a frequency different from the sampling frequency of the first means. For example, the first means is set to sample the first signal (fluctuation detection signal) at a first period, and the second means is set to perform the operation for forming the second signal (a driving signal for operating an image blur prevention means) on the basis of a plurality of data sampled by the first means at different timings at a second period longer than the first period so as to cope with a high-frequency first signal, thereby improving the processing performance of a system for digitally processing a signal for image blur prevention, against a high-frequency first signal.
