Light source apparatus for endoscope and light-emission amount control method for the same
In a light source apparatus for endoscope, when a light-emission amount of a second light source is less than or equal to a predetermined light-emission amount, a light source control circuit performs a first light-emission amount control of changing the light-emission amounts of the first to third light sources so as to allow a color balance to be maintained at a predetermined color balance. When the light-emission amount of the second light source is greater than the predetermined light-emission amount, the light source control circuit performs a second light-emission amount control of changing the light-emission amount of the third light source by a method different from the first light-emission amount control while changing the light-emission amounts of the first and second light sources by the same method as the first light-emission amount control so as to allow the color balance to be different from the predetermined color balance.
