Abstract
A digital camera includes: an evaluation value calculation unit that calculates a focal point evaluation value that changes in correspondence to a position assumed by a focus lens based upon image signals; a focal adjustment unit that executes an AF search by detecting a focus match position based upon resulting focal point evaluation values and driving the focus lens to the focus match position; a face recognition unit that recognizes a face of a person in an image by analyzing the image signals; a distance calculation unit that determines an approximate distance to the face based upon the recognized face size; and a lens position determining unit that determines a focus lens position to be set as a start point of the AF search by the focal adjustment unit based upon the approximate distance to the face having been determined by the distance calculation unit.
