Provided is an endoscope system capable of reliably setting correction information inherent in imaging elements. An endoscope system 1 includes an imaging apparatus 244 that outputs, as image information, an electrical signal photoelectrically converted from a plurality of pixels, outside the imaging apparatus, and a setting apparatus 3 that is connected to the imaging apparatus 244 so as to bi-directionally communicate with the imaging apparatus. The imaging apparatus 244 includes a recording unit 244c that records identification information for identifying the imaging apparatus 244. The setting apparatus 3 acquires, from a database 42 of a management server 4, the correction information corresponding to the identification information received from the imaging apparatus 244, transmits the correction information to the imaging apparatus 244, and causes the recording unit 244c to record the correction information.
