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 processor comprises a processor. The processor causes a light source to generate, as illumination light, light in a first wavelength band in which hemoglobin absorption is smaller than that in a green band and light in a second wavelength band which is different from the first wavelength band. The processor causes an endoscope to image a return light so as to output an image signal. The processor acquires a first image obtained by the light in the first wavelength band from the image signal and detects unevenness information on mucosa from the first image. The processor acquires a second image obtained by the light in the second wavelength band from the image signal and synthesizes the unevenness information with the second image so as to generate a display image in which an uneven region in the second image is emphasized.

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.
