Abstract: A cellular phone includes an illuminance sensor and a controller. The illuminance sensor detects illuminance in an ambient environment of the cellular phone. The controller refers to a control table in which a brightness region corresponding to an illuminance value and a set value related to a brightness value of a backlight are associated with each other and registered in advance. According to an illuminance value detected in the ambient environment, the controller sets a brightness value of the backlight to one of a plurality of set values. If the illuminance value is greater than the previous illuminance value and a brightness region corresponding to the previous illuminance value and a brightness region corresponding to the current illuminance value are different, the controller controls, after a predetermined time elapses, brightness of the backlight according to a set value greater than a set value previously set.
