• a circuit configured to acquire a signal for identifying a type of the image pickup device mounted on the second endoscope through the connection section when the first endoscope or the second endoscope is connected to the connection section;
• and
• a first discrimination section configured to determine whether an endoscope connected to the connection section is the first endoscope or the second endoscope based on the signal acquired by the circuit.
