  • Publication number: 20040109081
    Abstract: The CPU (13) continuously moves a focusing lens (2) along an optical axis by supplying a control signal to a motor driver (171a) to start continuously driving a focusing motor (stepping motor) (170a). The CPU (13) calculates an AF evaluation value based on high frequency components contained in an image signal output from a CCD (4) by driving the CCD (4) to operate for exposure with a predetermined period while continuously moving the focusing lens (2) and moves the focusing lens (2) to a position that maximizes the AF evaluation value.
