1. An endoscope system, configured to observe biological information on an observation object in a biological information observation mode, and configured to correct the biological information observation mode in a correction mode, the endoscope system comprising:
a light source unit that includes a first blue light source, a green light source, a red light source, and a second blue light source, the first blue light source is configured to emit first blue light, the green light source is configured to emit green light, the red light source is configured to emit red light, and the second blue light source is configured to emit second blue light having a longer central wavelength than a central wavelength of the first blue light;
wherein the light source unit is configured to output the second blue light in the biological information observation mode, and to output the green light and a white light in the correction mode,
the endoscope system further comprising a processor configured to:
calculate a compensation amount using a correction image having a biological information obtained by imaging the observation object using the green light;
correct a correlation to be used in the biological information observation mode using the compensation amount;
calculate, using the corrected correlation, biological information based on an image obtained by imaging the observation object using the second blue light; and
display a white light image which is obtained by imaging the observation object using the white light, on a display unit in the correction mode of the endoscope system,
wherein at least the first blue light source, the green light source, and the red light source are configured to emit simultaneously to output the white light.
