An endoscope apparatus includes an endoscope having a lens, an actuator, and an endoscope memory, and a processor having a driving circuit and a processor memory and connected to the endoscope. The processor judges whether there is abnormality or not in at least one of the actuator or the driving circuit by using information on a signal transmitted from the driving circuit to the actuator, first judgement information read from the endoscope memory, and second judgement information read from the processor memory.
