内視鏡装置１は、第１の光、第２の光及び第３の光を含む複数の照明光を照射する照明部３と、被検体からの戻り光を撮像する撮像部１０）と、第１〜第３の光の照射によって撮像された第１〜第３の画像に基づいて、表示画像を生成する画像処理部１７を含む。第１の光のβカロテンの吸光度と第２の光のβカロテンの吸光度の差を第１吸光度差とし、第１の光のメトミオグロビンの吸光度と第２の光のメトミオグロビンの吸光度の差を第２吸光度差とした場合において、第１吸光度差は第２吸光度差に比べて小さい。また第３の光のピーク波長は、第１の光のピーク波長及び第２の光のピーク波長と異なる。 An endoscope apparatus includes: an illumination device emitting first to third illumination light; an imaging device capturing an image using return light from a subject; and a processor including hardware. The processor generates a display image based on first to third images captured with the first to third light emitted. A first absorbance difference (difference in absorbance of β-carotene between the first and second illumination light) is smaller than a second absorbance difference (difference in absorbance of metmyoglobin between the first and second illumination light). A peak wavelength of the third illumination light differs from peak wavelengths of the first and second illumination light. Based on the first to third images, the processor generates the display image that displays a thermally denatured muscle layer, a fat layer, and a muscle layer that is not thermally denatured of the subject, in an identifiable manner from each other.
