1. A camera having a focus adjusting system and a face recognition function, comprising:

  • an image pickup device for capturing an object image formed via a photographing optical system including a focusing lens group movable along an optical axis;

    a focus adjusting device which performs a focus search process, wherein said image pickup device is activated to capture an object image at each of a plurality of different positions of said focusing lens group in said optical axis direction while said focusing lens group is moved along said optical axis to detect an in-focus lens position of said focusing lens group in said optical axis direction, based on image signals of said object images obtained at said plurality of different positions of said focusing lens group, and wherein said focusing lens group is moved to said in-focus lens position detected by said focus search process; and

    a face recognition device for recognizing a face image based on said image signals,wherein, when said face recognition device recognizes said face image, said focus adjusting device performs said focus search process so that said focusing lens group moves toward a near extremity in the case where the area size of said face image is smaller than a predetermined threshold value, and so that said focusing lens group moves toward a far extremity in the case where said area size of said face image is one of equal to and greater than said predetermined threshold value.
