PROBLEM TO BE SOLVED: To provide an endoscope system, a processor device, and an operation method of the endoscope system that can reduce artifact and calculate an accurate oxygen saturation degree.SOLUTION: An endoscope system includes: an oxygen saturation degree correction unit for calculating a variation Δ of an oxygen saturation degree Sof the latest second period from an oxygen saturation degree Sof the past first period, maintaining the value of the oxygen saturation degree Sof the second period when the variation Δ is below a threshold Th, and correcting the oxygen saturation degree Sof the second period to a value that causes the variation Δ to be the threshold Th when the variation Δ is the threshold Th or more; and an oxygen saturation degree image creation unit for creating an oxygen saturation degree image using the oxygen saturation degree Sof the second period.SELECTED DRAWING: Figure 15 |
