Title: ENDOSCOPE SYSTEM AND OPERATION METHOD THEREOF
Abstract:
An endoscope system is provided which can accurately calculate biological feature values such as oxygen saturation even in situations in which a variety of variable factors occur, such as misalignment between frames; an operation method of the endoscope system is also provided. Image variation for correction, obtained during a calibration mode, and image variation for measurement, obtained during a measurement mode, are compared. On the basis of the result of this comparison, a provisional correction value satisfying a specific condition is determined, from provisional correction values stored in a correction value storage unit, as the measurement correction value to be used for correction in the correction unit.
