Abstract
An endoscope apparatus includes an objective optical system that is provided at a distal end portion of an insertion portion of an endoscope which can be inserted into a body cavity of a subject; a temperature sensor unit that detects a temperature of the distal end portion; a heating unit that can generate heat for preventing fogging of the objective optical system; a timer that measures a time period during which the temperature of the distal end portion detected by the temperature sensor unit is equal to or lower than a predetermined temperature; and a control unit that performs control so as to cause the heating unit to generate the heat when the time period measured by the timer continues for a predetermined time period or longer.
