Beschreibung
Zusammenfassung:	A projector device includes: a storage unit storing lighting pattern information indicating the lighting start timing of an LED and the time sequence of a lighting continuation period from the lighting start timing; a drive control unit that causes the LED to light on the basis of the lighting pattern information; and a voltage measurement unit. The voltage measurement unit refers to the lighting pattern information and determines, for a target period, a lighting continuation period that is longer than a preset set period. The voltage measurement unit measures the forward voltage within the determined target period from the start of the period until a timing after the set period has elapsed.
