ABSTRACT:
An imaging device that can shorten focus searching search times and enable correct focusing in accordance with shooting conditions. An autofocus function operates when a shutter button of a digital camera is half-pressed. At this time, a current shooting mode, which was selected in advance by a photographer operating a variety of buttons, is acquired. In accordance with the acquired shooting mode, a focusing lens moves to a search start position. Also, a direction in which the focusing lens will move is decided in accordance with the shooting mode. The focusing lens is moved and an in-focus position is thereby found. Then the focusing lens is adjusted to the in-focus position.
