Abstract
In an electronic device, a control unit determines a state of changes of tilt angles detected by a tilt sensor, modifies at least one of control information stored in a control information storage unit, and a tilt direction and tilt angle detected by the tilt sensor, depending on the determined state of the changes, and changes the display orientation of a display unit on the basis of the modification result. The tilt sensor detects the tilt direction and tilt angle of the display unit with respect to the vertical downward direction. The control information storage unit stores the control information indicating correlations between display orientations of the display unit and tilts of the own device. A detected tilt data storage unit stores detected tilt data indicating a history of tilt directions and tilt angles detected by the tilt sensor.
