Abstract:
1. An image-blur compensating device comprising: an optical component configured to compensate blur in an image; an actuator configured to drive the optical component; a displacement detector configured to detect a position of the optical component changed by the actuator; an angular velocity detector configured to detect an angular velocity applied from outside; a target displacement calculator configured to calculate a driving amount when the actuator has driven the optical component based on the angular velocity detected by the angular velocity detector and the position detected by the displacement detector, and to compensate the driving amount based on an amount of influence induced by the actuator on the position of the optical component detected by the displacement detector and the calculated driving amount to generate a compensated driving amount; and a driver configured to drive the actuator based on the compensated driving amount calculated by the target displacement calculator.
