ABSTRACT:
An image-blur compensating device includes an optical component configured to compensate blur in an image, an actuator driving the optical component, a displacement detector detecting a position of the optical component changed by the actuator, an angular velocity detector detecting an angular velocity applied from outside, and a target displacement calculator calculating a driving amount when the actuator has driven the optical axis changing unit based on the angular velocity detected by the angular velocity detector and the position detected by the displacement detector. The target displacement calculator then obtains, as a result of compensating an amount of influence on the position of the optical component, a driving amount when driving the actuator based on the calculated driving amount. The image-blur compensating device further includes a driver driving the actuator based on the driving amount calculated by the target displacement calculator.
