    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 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.

    Abstract: An image processing device includes: an image acquiring unit configured to acquire a plurality of images at different imaging time which images are captured when illumination light in different wavelength bands is emitted; and a processor including hardware. The processor is configured to generate a low-resolution image by lowering resolution of at least one image in the plurality of images, and detect light-absorption information at a certain depth based on a correlation between images which are in an image group including the low-resolution image and the plurality of images, which are captured with the illumination light in different wavelength bands, and at least one of which is the low-resolution image.
