Abstract

A displacement amount controlling method for enabling the displacement to be stopped or held at a give amount of displacement of an ion conductive composite actuator and a displacement amount controlling device therefor are provided. The method includes a focus judging step of judging the focus of an image captured through a lens following the displacement of an ion-conductive composite actuator caused by application of a drive voltage, a drive step of controlling the drive voltage applied to the ion-conductive composite actuator depending on the result of the focus judgment so as to focus the image, and a repeating step of repeating the focus judging step and the drive step until the image is substantially focused.
