Abstract
A first high-pass filter comprising a low-pass filter which allows only a frequency component of an input signal less than or equal to a first frequency to pass, a latch unit which latches an output of a low-pass filter according to a control signal, and a calculating unit which outputs a difference between an input signal and an output of the latch unit are provided on an image stabilization circuit. When latching in the latch unit is released, a held value of the latch unit is stepwise changed to the output value of the low-pass filter. Such a first high-pass filter is used in a centering process of an optical element.
