摘要

A lens drive controlling apparatus includes a zooming lens (102), a focusing lens (105) driven in follow-up relation to a movement of the zooming lens (102) on the basis of a predetermined characteristic, a speed sensor for detecting a driving speed of the zooming lens (102), and a control circuit (117) for determining a driving speed of the focusing lens (105) on the basis of a detection result provided by the speed sensor.
