ABSTRACT:
For image blur prevention, the present invention discloses an apparatus comprising an operation device which performs an initial setting for the image blur prevention (by determining a DC offset in the high-pass filter calculation on an output signal of an image blur detection sensor, from the output signal of the image blur detection sensor); and a determination device which determines a state of a signal (whether it is larger than a predetermined value) influencing the initial setting (the above-mentioned output signal of the image blur detection sensor) at a time when the operation device performs the initial setting operation, thereby enabling appropriate initial setting and thus achieving appropriate image blur prevention. If the output signal is determined as larger than the predetermined value, the initial setting is performed for example in a state where the direction of the optical apparatus is being altered. In such case the initial setting is determined as improper and is performed again.
