Abstract
An endoscope system includes a processor, and the processor acquires a plurality of spectral images for calculation of oxygen saturation that are used to calculate oxygen saturation of an object to be observed and spectral images for correction that are used to calculate correction values to be used to correct the oxygen saturation, creates a linearity correction table that is used to linearize a relationship between an amount of light incident on an image sensor and pixel values of the spectral images for correction, and calculates the correction values using the spectral images for correction that have been subjected to linearity correction using the linearity correction table.
