An endoscope apparatus includes: a light source section configured to generate first light emitted to a subject having hemoglobin and second light; an image pickup section configured to receive light from the subject irradiated with the light from the light source section to generate an image pickup signal; an image generation section configured to generate an observation image of the subject from a first image pickup signal generated by receiving light from the subject irradiated with the first light and a second image pickup signal generated by receiving light from the subject irradiated with the second light; and a control section configured to control a spectral product of at least one of the first light and the second light such that a spectral product in the wavelength band of the first light falls within 50% to 150% of a spectral product in the wavelength band of the second light.
