Endoscope system

A method of controlling an endoscope system, the method comprising:

• detecting temperature at an front end of the endoscope by a plurality of thermometers disposed at the front end;
• determining whether or not highest temperature, from among a plurality of temperatures detected by the plurality of thermometers, is equal to or higher than a first threshold value;
• and
• controlling, based on determination result, electrical power supplied to a heater disposed at the front end and configured to heat a predetermined member disposed at the front end.

A processor for being connected to an endoscope including a heater configured to heat a predetermined member disposed at a front end of the endoscope, and a plurality of thermometers configured to detect temperatures at the front end, the processor comprising:

• a power source configured to supply electrical power to the heater;
• determination circuitry configured to determine whether or not highest temperature, from among the temperatures detected by the plurality of thermometers, is equal to or higher than a first threshold value;
• and
• a power controller configured to control, based on determination result of the determination circuitry, the electrical power supplied by the power source to the heater.

An endoscope comprising:

• an insertion portion whose front end is inserted inside a subject;
• a plurality of thermometers disposed near a predetermined member disposed at the front end and configured to detect temperatures at the front end, the temperatures detected by the plurality of thermometers being output to determination circuitry configured to determine whether or not highest temperature, from among the temperatures, is equal to or higher than a first threshold value;
• and
• a heater disposed at the front end and configured to heat the predetermined member by electrical power, the electrical power being controlled and supplied based on determination result of the determination circuitry.
