  • Publication number: 20080252773
    Abstract: In a digital still camera, an image is picked up by detecting object light from a lens system having a focus lens. A region of a human face is detected within the image by image analysis thereof. An estimated distance of the facial region is determined according to a size of the facial region. A lens moving distance of the focus lens is determined according to the estimated distance. A contrast value of the image is acquired in moving the focus lens by the lens moving distance. An in-focus lens position is determined according to the contrast value, to set the focus lens in the in-focus lens position. Furthermore, before the image pickup step, so great an aperture value of the lens system on the optical path is set as to enable image pickup of the facial region within a depth of field.
