Endoscope system and method of operating the same

Abstract

An endoscope system includes a processor, in which the processor performs exposure amount control based on an endoscope image captured by an endoscope including an imaging element, calculates brightness information indicating a degree of brightness of an edge portion of the endoscope image, and controls a tracking speed of the exposure amount control according to the brightness information. The brightness information is compared with past brightness information, which is the brightness information in the past, and a suppression coefficient for suppressing a change amount or a change rate of an exposure amount, which is decided according to a comparison result, is applied to the exposure amount control to control the tracking speed.
