Provided are an endoscope system, an image processing device, an image processing method, and a program capable of simultaneously observing color images and oxygen saturation levels without enlarging the device. The endoscope system (1) has a color image generating unit (911) that uses the light source device (6) to irradiate the subject with a plurality of narrow-band lights, and records the first image data and correction data generated by the imaging element (222). The correction data recorded in the part (921) to generate color image data; and the oxygen saturation calculation part (912), which uses the first image generated by the imaging element (222) when the light source device (6) irradiates the object with three narrow-band lights. 1 The oxygen saturation of the subject is calculated from the R pixel value of the R pixel and the G pixel value of the G pixel included in the image data. |
