    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 comprises a processor. The processor causes the light source device to produce narrow band light as illumination light, and the narrow band light has a peak wavelength between a wavelength band including a local maximum of a hemoglobin absorption characteristic and a wavelength band including a local minimum of the hemoglobin absorption characteristic. The processor receives an image signal from the imaging device that outputs the image signal based on return light. The processor uses an image produced in response to the image signal to identify a state of the living body by identifying at least one of whether or not stomach mucosa is in a sterilized state, or whether or not the stomach mucosa is inflamed mucosa, outputs state identifying information indicating the state of the living body, and controls wavelength characteristics of the illumination light based on the state identifying information.
