Abstract: A mobile terminal has a touch screen and a sensor configured to sense a change of an orientation of this mobile terminal. CPU of this mobile terminal is configured to, when the sensor senses a change of the orientation of the mobile terminal, determine whether or not a two-point long touch operation is being performed on the touch screen. CPU is configured to, when it is determined that a two-point long touch operation is not being performed, turn a display orientation of an image based on a sensing result of the sensor. CPU is configured to, when it is determined that a two-point long touch operation is being performed, forbid such turning until the orientation of the mobile terminal is changed next time.
