Abstract: An endoscope apparatus includes: an illumination device emitting first and second lights; an imaging section capturing an image of return light from a subject based on emission by the illumination device; and a processor including hardware. The first light has a peak wavelength within a first wavelength range including a wavelength at which absorbance of a biological mucosa reaches a largest value. The second light has a peak wavelength within a second wavelength range including a wavelength at which absorbance of a muscle layer reaches a maximum value, and absorbance of the second light by fat is lower than that by the muscle layer. The processor displays the biological mucosa and the muscle layer in an identifiable manner based on a first image corresponding to the first light, and displays the muscle layer and the fat in an identifiable manner based on a second image corresponding to the second light.

Abstract: An endoscope system includes an image acquisition section, an attention area setting section, and a scaling section. The image acquisition section acquires a captured image that includes an object image. The attention area setting section sets an attention area within the captured image based on information from the endoscope system. The scaling section performs a local scaling process that relatively enlarges the attention area as compared with another area.

Abstract: An image processing device includes an image acquisition section, a distance information acquisition section, a concavity-convexity information acquisition section, a determination section that determines whether or not to exclude or reduce extracted concavity-convexity information corresponding to each given area of a captured image, and a concavity-convexity information correction section that excludes the extracted concavity-convexity information corresponding to the given area for which the determination section has determined to exclude the extracted concavity-convexity information, or reduces the degree of concavities and convexities represented by the extracted concavity-convexity information corresponding to the given area for which the determination section has determined to reduce the extracted concavity-convexity information. The concavity-convexity information acquisition section excludes a structure that is more global than a desired concavity-convexity part from the distance information based on known characteristic information to extract information about the desired concavity-convexity part as the extracted concavity-convexity information.

Abstract: An endoscope apparatus includes a processor. An image signal includes a first image signal corresponding to first light and a second image signal corresponding to second light. The processor determines at least one of whether or not a submucosa region or a bleeding region is included in an image based on the image signal. In a case where the submucosa region is included, the processor performs conversion processing that increases a combination ratio of the second image signal to the first image signal in an image region including the submucosa region, and allocates a combined image signal to a G-channel. In a case where the bleeding region is included, the processor performs conversion processing that increases a combination ratio of the first image signal to the second image signal in an image region including the bleeding region, and allocates the combined image signal to the G-channel.

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.

Abstract: An endoscope apparatus includes an illumination device emitting a plurality of lights with different wavelength bands at least two different timings in time series, and a processor including hardware. The plurality of lights includes a first light and a second light. The processor is configured to generate a highlighted image in which a specific structure under a mucus membrane is highlighted, based on a plurality of images obtained by the emission of the plurality of lights. The illumination device emits the first light and the second light continuously. The first light has a first wavelength band corresponding to a luminance component of the highlighted image. The second light has a second wavelength band that enables capturing of an image of the specific structure with higher contrast than the first light.
