Claim 9:
10. An endoscope image processing apparatus comprising:
a processor configured to:
acquire signal intensity information based on a predetermined parameter indicating a present operation state,
wherein the signal intensity information is a ratio of (i) signal intensity of a first image-pickup signal of a first image, the first image-pickup signal being generated based on return light from an object irradiated with a first light having a central wavelength different from a predetermined central wavelength of a first light having a wavelength band belonging to a red color gamut, with respect to (ii) reference signal intensity of the first image-pickup signal when the object is irradiated with the first light having a wavelength belonging to the red color gamut; and

perform, based on the signal intensity information, control to maintain a brightness ratio of the first image and a second image at a constant ratio, the second image being picked up based on return light from the object irradiated with a second light, a wavelength band of the second light being out of the wavelength band of the first light and having a shorter wavelength than the first light.
