Abstract
A current having a light emission period current value for emitting first illumination light or second illumination light is caused to flow through a V-LED in a first light emission period for emitting the first illumination light or a second light emission period for emitting the second illumination light. A current having a light non-emission period current value for applying a VF voltage is caused to flow through a pseudo load in a light non-emission period that is provided between the first light emission period and the second light emission period, or between the second light emission periods and in which the first illumination light and the second illumination light are not emitted.
