Abstract: An endoscope connected to a control apparatus, includes an imager, a status signal acquisition circuit, and a preprocessor. The imager images a subject to generate an imaging signal related to the subject. The status signal acquisition circuit receives a status signal indicating an operation status or an operation mode of the endoscope or of the control apparatus. The preprocessor processes the imaging signal according to the status signal received via the status signal acquisition circuit.
