Abstract

Violet light and green light are mixed and emitted at a first light amount ratio. A contrast difference value ΔCof first mixed color light emission between a blood vessel contrast of a blue image of first mixed color light emission and a blood vessel contrast of a green image of first mixed color light emission at a specific blood vessel depth satisfies a first condition, and a cross-point blood vessel depth VDof first mixed color light emission corresponding to a cross-point CPbetween the blood vessel contrast of the blue image of the first mixed color light emission and the blood vessel contrast of the green image of the first mixed color light emission satisfies a second condition.
