Classification: CPC A | IPC A

Claim 7:
8. An operation method for a light source device including a plurality of semiconductor light sources, a pseudo load connected to each of the semiconductor light sources, and a light source processor, the operation method comprising:
causing the light source processor to execute, in a case where the plurality of semiconductor light sources are controlled such that first illumination light and second illumination light having different spectra are automatically switched and emitted according to a specific emission pattern,
a step of causing a current having a light emission period current value for emitting the first illumination light or the second illumination light to flow through the semiconductor light source in a first light emission period for emitting the first illumination light or a second light emission period for emitting the second illumination light; and
a step of causing a current having a light non-emission period current value for applying a VF voltage to the 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.
