The control unit 130 may calculate the position of the pointer based on the calculated height difference.

Also, the controller 130 can calculate the pointer position by prioritizing any one of the plurality of factors on the basis of the above-described pointer position calculation.

For example, the control unit 130 may calculate the pointer position by prioritizing the distance d2 from the distance factors to the face of the photographee relative to other factors. Accordingly, the control unit 130 can greatly change the positional variation of the pointer calculated by the variation of the distance d2 to the face of the to-be-photographed person, compared with the positional variation of the pointer calculated by the variation of other distance factors.

Referring again to FIG.

The control unit 130 displays the pointer 200 on the output unit 140 based on the calculated position of the pointer (S140).
