Abstract
A portable display device comprises: a tilt detection unit detecting an angle of rotation, measured between a vertical plane component of a tilt vector of a predetermined reference line in the display and a gravitational vector, as a display tilt; a facial orientation specification unit recognizing a face of a person facing the display and specifying an upright orientation of the face; a terminal orientation determination unit establishing a plurality of angle ranges, and determining whether the display tilt newly detected by the tilt detection unit exceeds a given angle range and enters another angle range, the given angle range including the angle detected by the tilt detection unit upon updating a previous display orientation; and a control unit causing the facial orientation specification unit to begin the specification when the terminal orientation determination unit makes an affirmative determination, and updating the display orientation according to the specified upright orientation.
