Abstract
An IC chip that controls a driving mechanism that drives an optical element based on a control signal is provided. The IC chip comprises a generation unit that generates the control signal for moving the optical element to a target position while suppressing sound generated due to the driving by the driving mechanism, based on a detection signal indicating a position of the optical element and relationship information indicating a relationship between an index corresponding to a magnitude of the sound generated due to the driving by the driving mechanism and a position of the optical element.
