Abstract
A rotational movement in the horizontal direction of a lens unit is detected by a horizontal angular velocity sensor, amplified by an amplifier and converted to a digital signal by an A/D converter for input to a focus controlling circuit. When a value obtained by multiplying a focal length detected by a zoom lens reference position sensor by a detected amount of change in angular velocity exceeds a predetermined threshold value, focus controlling circuit stops the focusing operation by a focus motor driver and a focus motor.
