A video processor includes: a region extracting circuit that receives an input of a first image signal obtained by forming an image of a subject irradiated with first narrow band light including a wavelength that is minimally absorbed by blood within a green wavelength band, the image of the subject including a bleeding point, and extract a blood pool region having a blood concentration that is lower than a blood concentration of the bleeding point in a region representing the blood in the first image signal; and an image generating circuit that raises a luminance value of the blood pool region in either the first image signal or a second image signal obtained by forming an image of the subject irradiated with second narrow band light whose wavelength is shorter and which is more absorbed by the blood than the first narrow band light.
