Patent ID: 8860794

Claim:
An endoscope system comprising: an imaging apparatus that outputs, as image information, an electrical signal photoelectrically converted from a plurality of pixels, outside the imaging apparatus; and a processing apparatus that is connected to the imaging apparatus so as to bi-directionally communicate with the imaging apparatus, wherein the imaging apparatus includes a first recording unit that records identification information for identifying the imaging apparatus, wherein the processing apparatus includes: a second recording unit that records correction information for correcting characteristics of the imaging apparatus in association with the identification information; and a control unit that acquires, from the second recording unit, the correction information corresponding to the identification information received from the imaging apparatus and transmits the correction information to the imaging apparatus, and wherein the control unit acquires the correction information recorded in the first recording unit, and if the acquired correction information is different from the correction information recorded in the second recording unit, the control unit transmits the correction information recorded in the second recording unit in association with the identification information to the imaging apparatus and causes the first recording unit to record the correction information recorded in the second recording unit, which is received from the control unit.
