摘要:
An imaging apparatus includes a correction unit, a vibration detection unit, a filter passing and outputting frequency of a predetermined band of vibration signals periodically entered from the vibration detection unit: the filter setting, as intermediate value, sum of a value based on a vibration signal of current period and a value based on a vibration signal of last period and setting, as output signal, a value obtained by adding a value based on intermediate value of the current period and a value based on intermediate value of the last period, a calculation unit calculating vibration correction amount, a driving control unit driving the correction unit by using the vibration correction amount, and an offset unit performing feedback control so that an intermediate value is shifted to predetermined value by changing the intermediate value and an offset value added to a signal based on output from the vibration detection unit.
