1. An endoscope apparatus comprising:an endoscope including an observation optical system, the observation optical system including a lens drive mechanism; and
an image processing apparatus including a processor including hardware, the image processing apparatus being connected to the endoscope, the endoscope apparatus comprising:an actuator provided in the endoscope and configured to drive a lens relating to the lens drive mechanism;
a memory configured to store determination information for a heat generation determination; and
a position detecting sensor provided in the endoscope, the position detecting sensor being configured to detect a position of the lens by being supplied with an input voltage and an input current and outputting a position detection signal,
the processor being configured to:determine whether or not the position detecting sensor is in a first heat generating state based on the determination information and one or more of the input voltage or the input current; and
if the position detecting sensor is determined to be in the first heat generating state, make the input current and the input voltage supplied to the position detecting sensor be zero so as to halt actuation of the position detecting sensor, or make the input current and the input voltage supplied to the position detecting sensor be equal to or below a predetermined current value so as to reduce heat generated by the position detecting sensor.
