Claim 18:
19. A method of controlling an endoscope system, the method comprising:
selecting, as illumination light for illuminating an object including a biological tissue present in a subject, light in combinations of one or more wavelength bands out of the light in the plurality of wavelength bands and set first illumination light and second illumination light formed by differentiating a ratio of the light in the combinations;
controlling the light source apparatus to alternately irradiate, from the light source apparatus, the first illumination light and the second illumination light set by the processor; and
determine an analysis result related to presence or absence of an abnormal finding by analyzing a first image obtained by an image sensor configured to pick up an image of return light from the object on which the illumination light is irradiated when the first illumination light is irradiated and setting, based on the analysis result for the first image acquired by the image sensor when the first illumination light is irradiated, a light amount ratio of the light in the plurality of wavelength bands included in the second illumination light to be irradiated next;
wherein the method further comprising:
setting, as the first light amount ratio, a light amount ratio for setting a ratio of violet light included in the first illumination light smaller than a ratio of blue light and setting a ratio of amber light included in the first illumination light smaller than a ratio of red light, and

analyzing the first image to acquire, as the analysis result, an evaluation result relating to an atrophy degree of a mucous membrane included in the first image.
