Patent ID: 7006139

Claim:
A lens control apparatus comprising: a movable part which is movable along an optical axis for performing focus adjustment; an actuator which drives said movable part; a position-of-movable-part detecting unit which detects a position of said movable part; a focus control unit which determines a state of focus and supplies a driving signal which causes said movable part to move toward an in-focus position, according to the determined state of focus; and a position control unit which performs position control of said movable part via said actuator by updating the driving signal by a plurality of times during a vertical synchronizing period, and wherein said actuator is a linear motor, and said position control unit updates a target position n times during the vertical synchronizing period by an amount of movement, s/n, at a time with respect to an amount of movement, s, by which said movable part moves at the predetermined speed, and uses a driving signal corresponding to the updated target position as the driving signal to be supplied to said linear motor by said focus control unit.
