<p>An auto focus control apparatus includes a focal value calculation unit 10 for calculating a focal value from a signal of an image frame. A focus lens driving unit 30 moves a focus lens to a desired position and a control unit 50 determines position movement of a subject based on the focal value calculated by the focal value calculation unit. A pre-scan is executed according to the movement of the focus lens by controlling the focus lens driving unit to move the focus lens at set frame intervals when the position of the subject is moved, skipping lens moving frame corresponding to the time when the focus lens moves during the pre-scan.</p> |
