1. An endoscope control device comprising:
a processor including hardware, the processor being configured to:
cause a light source device to produce illumination light including first narrow band light and second narrow band light, the first narrow band light and the second narrow band light having peak wavelengths between a wavelength band including a local maximum of a hemoglobin absorption characteristic and a wavelength band including a local minimum of the hemoglobin absorption characteristic, and the peak wavelength of the second narrow band light being a band longer than the peak wavelength band of the first narrow band light;
receive an image signal from an imaging device that outputs the image signal based on return light;
use an image produced in response to the image signal to identify a state of a living body by identifying at least one of whether stomach mucosa is in a state in which sterilization has not been performed or a state after sterilization has been performed, or whether or not the stomach mucosa is inflamed mucosa;
output state identifying information indicating the state of the living body; and
control wavelength characteristics of the illumination light based on the state identifying information, to:
set a first weight coefficient as a weight coefficient of a light amount of the second narrow band light with respect to a light amount of the first narrow band light upon detection that the state of the living body is in a first state; and
set a second weight coefficient larger than the first weight coefficient as the weight coefficient upon detection that the state of the living body is in a second state different from the first state.
