Abstract
An image capture device includes a focusing unit, a focus driving unit and an autofocus control unit; the focusing unit is provided to focus on a subject. The focus driving unit is provided for driving the focusing unit to driving-target position. The autofocus control unit is provided to control driving of the focus driving unit according to a determination of executing or omitting a one-way-driving-control. One-way driving control controls driving direction of the focus driving unit into a predetermined direction at a peripheral range before driving-disactivation of the focus driving means, determined based on a shooting-condition.
