PROBLEM TO BE SOLVED: To provide an information terminal capable of displaying a battery power in which effect of load variation is corrected. SOLUTION: A ROM 34 stores a correspondence table between the battery power and the battery voltage, for a prescribed battery temperature and the magnitude of the load current. A voltage detection circuit 40 detects the battery voltage. A temperature detection circuit 42 detects the battery temperature. A CPU 10 acquires an operational mode of the information terminal, wherein the magnitude of the load current corresponding to the operational mode is calculated. An interpolation table is created by the interpolation in which the correspondence table stored in the ROM 34 is related to the battery temperature and the load current. In the created interpolation table, the battery power corresponding to the battery voltage detected by the voltage detection circuit 40 is acquired. COPYRIGHT: (C)2007,JPO&INPIT
