1. An information display device comprising:

  • an orientation change degree computation unit that computes a degree of change of a state of orientation of the information display device;

    an orientation change degree determination unit that determines whether the degree of change of the state of orientation of the information display device computed by the orientation change degree computation unit is equal to or more than a threshold;

    an image capture unit controller that activates an imaging unit upon the orientation change degree determination unit determining that the degree of change of the state of orientation of the information display device is equal to or more than the threshold;

    a face detection unit that detects a person'"'"'s face in an image obtained by imaging of the imaging unit;

    a face direction specification unit that specifies a vertical orientation of the person'"'"'s face detected by the face detection unit;

    a display direction determination unit that determines whether a vertical orientation of a screen display that is displayed on a display unit is the same orientation as the vertical orientation of the person'"'"'s face specified by the face direction specification unit; and

    a display direction switch unit that switches the vertical orientation of the screen display that is displayed on the display unit to the same orientation as the vertical orientation of the person'"'"'s face upon the display direction determination unit determining that the vertical orientation of the screen display that is displayed on the display unit and the vertical orientation of the person'"'"'s face are not the same orientation.
