Abstract: This invention improves the convenience of viewing three-dimensional image displays. A mobile communications handset can accomplish three-dimensional image displays using image data received by a communications unit and a broadcast reception unit through a display unit provided with a parallax barrier panel. A control unit automatically performs actions to record the image data as an auxiliary recording while the three-dimensional image display is being performed when the three-dimensional image display is performed using the received image data. That is to say, recording of image data relating to the three-dimensional image display is performed automatically in preparation for cases where the display cannot be viewed three-dimensionally due to viewing conditions.
