Abstract
Oxygen saturation is calculated on the basis of a calculation value with reference to an oxygen saturation calculation table TBL. A specific colorant concentration of a specific colorant other than hemoglobin is calculated on the basis of B3 image signals and G1 image signals. Whether or not a first difference D1 between the specific colorant concentration and a reference concentration is in a specific range is monitored. A correction notification related to correction of the oxygen saturation calculation table TBL is performed on the basis of a result of the monitoring of the specific colorant concentration.
