Abstract
In a position controller, a driving mechanism and an image pickup system according to the present invention, an operation of controlling a position of a movable member is performed by using, as a reference value, a first resistance value giving a first change point at which a resistance change rate per unit temperature change in a shape-memory-alloy member changes from a first rate to a second rate different from said first rate. Thus, the present invention makes it possible to control the position of the movable member based on a resistance of a shape-memory-alloy member, without a position sensor.
