Abstract

In an electronic device including a discharge lamp, and a lamp power supply section that supplies power to the discharge lamp, a control section makes the lamp power supply section execute a lamp refresh process of supplying power necessary for generation of a halogen cycle to the discharge lamp at predetermined time intervals during low power operation in which the discharge lamp is lighted with power less than the rated power. Further, the control section records, in a recording section (non-volatile memory), a control instruction which is issued to the lamp power supply section during low power operation.
