Abstract: 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 ß-carotene between the first and second illumination light) is larger 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.

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.

Abstract: An endoscope apparatus includes: a light source apparatus; an image pickup apparatus configured to pick up an image of an object including a region containing hemoglobin irradiated with illumination light and output an image-pickup signal; and a processor. The processor performs predetermined image processing on at least one of a first image and a second image and outputs the one image, the first image being obtained by performing image pickup of the object irradiated with the first light, the second image being obtained by performing image pickup of the object irradiated with the second light, and generates an observation image by using the first and second images obtained as a processing result of the predetermined image processing.
