Abstract: An endoscope system includes: a light source including one or more semiconductor light sources; an image pickup apparatus configured to pick up an image of the object irradiated with the illumination light to obtain the image; and a processor. The processor is configured to detect brightness of the image, to change one of a current value and an application period of a current applied to the semiconductor light source when the brightness of the image belongs to a first brightness range, to change the brightness of the image by predetermined processing, to which the image is subjected, when the brightness of the image belongs to a second brightness range, and to change the other of the current value and the application period of the current applied to the semiconductor light source when the brightness of the image belongs to a third brightness range.
