Abstract
An endoscope system generates first to third color image data by imaging biological tissue illuminated with first to third light. The endoscope system uses a first light intensity ratio of the first light and the second light, and/or an imaging sensitivity of the image sensor, to correct a first ratio between multiple components of the first and second color image data, and the endoscope system calculates a first characteristic amount of the biological tissue based on the first corrected ratio. Furthermore, the endoscope system uses a second light intensity ratio between the second light and the third light to correct a second ratio between multiple components of the second and third color image data, and the endoscope system calculates a second characteristic amount of the biological tissue based on the second corrected ratio and the first characteristic amount.
