In the present invention, an endoscope apparatus has an identification unit which identifies the classification on the basis of scope ID information of an endoscopic scope, a storage unit which stores information regarding processing to be executed according to the classification of the endoscopic scope (a first SOP), and a control unit which reads a second SOP corresponding to the classification from the first SOP stored in the storage section on the basis of the result of the identification by the identification unit and sets the second SOP, and which, in the case where the information corresponding to the classification does not exist, performs switching so that predetermined information (a third SOP) is read from the first SOP stored in the storage unit and sets the predetermined information.
