Abstract: 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.

Abstract: An endoscope system includes a light source apparatus configured to cause light of a plurality of colors to be emitted at a first/second light amount ratio to generate first/second illumination light, an endoscope configured to generate an image pickup signal, and a processing apparatus including a processor. The processor causes the light source apparatus to emit light while switching light between the first/second illumination light, generates a first image signal from an image pickup signal related to the first illumination light, generates a second image signal from an image pickup signal related to the second illumination light and generates a corrected image signal in which color is enhanced based on the first and the second image signals. The second illumination light is light obtained by adjusting the second light amount ratio so that the second image signal related to a reference portion substantially indicates achromatic color.
