A control method to control a lamp, which is used as a heat generator, including detecting a temperature of lamp, comparing the detected temperature of the lamp with a predetermined reference temperature, turning off a power supply to the lamp when the detected temperature of the lamp exceeds the predetermined reference temperature, and when the lamp stays in a turned-off state for more than a first time amount, supplying a half wavelength pulse to the lamp at intervals according to a second time amount. According to the lamp control method, reducing the inrush of current to the lamp is possible without requiring additional hardware. When applied to electronic apparatuses, the lamp control method reduces maximum value of the inrush of current in the stand-by mode. |
