1. An endoscope apparatus comprising:
an endoscope:
a processor to which the endoscope is connected:
a lens arranged in the endoscope:
an actuator arranged in the endoscope and configured to drive the lens:
a driving circuit arranged in the processor and configured to drive the actuator by transmitting a signal to the actuator:
a first memory arranged in the endoscope and configured to store first judgement information for use in judging an abnormality of at least one of the actuator or the driving circuit, the first memory being configured to store the first judgement information including a first current threshold for use in judging the abnormality of a current of a first signal having a constant voltage and transmitted from the driving circuit to the actuator, and a second voltage threshold for use in judging the abnormality of a voltage of a second signal having a constant current and transmitted from the driving circuit to the actuator; and
a second memory arranged in the processor and configured to store second judgement information for use in judging the abnormality of at least one of the actuator or the driving circuit, the second judgement information being different from the first judgement information, the second memory being configured to store the second judgement information including a first voltage threshold for use in judging the abnormality of a voltage of the first signal, and a second current threshold for use in judging the abnormality of a current of the second signal, wherein
the processor judges whether there is the abnormality or not in at least one of the actuator or the driving circuit by using information on the first signal or the second signal transmitted from the driving circuit to the actuator, the first judgement information read from the first memory, and the second judgement information read from the second memory, and
the processor obtains at least one of a current value or a voltage value of the signal transmitted from the driving circuit to the actuator, and
when obtaining a current value of the first signal, the processor compares the obtained current value of the first signal with the first current threshold and judges that the abnormality exists when the current value of the first signal exceeds the first current threshold,
when obtaining a voltage value of the first signal, the processor compares the obtained voltage value of the first signal with the first voltage threshold and judges that the abnormality exists when the voltage value of the first signal exceeds the first voltage threshold,
when obtaining a voltage value of the second signal, the processor compares the obtained voltage value of the second signal with the second voltage threshold and judges that the abnormality exists when the voltage value of the second signal exceeds the second voltage threshold, or
when obtaining a current value of the second signal, the processor compares the obtained current value of the second signal with the second current threshold and judges that the abnormality exists when the current value of the second signal exceeds the second current threshold.
