a mirror display;
a three-dimensional camera disposed toward a front direction of the mirror display;
a motion sensor configured to sense a motion of a user; and
a controller configured to:
detect facial contours of a user from three-dimensional face images of the user that were photographed at least two different time points by the three-dimensional camera,
identify a change of the facial contours between the at least two different time points based on the detected facial contours,
control the mirror display to display information about the change of the facial contours,
activate the three-dimensional camera when the motion sensor detects the motion of the user,
