Abstract
An endoscope apparatus includes a light source device, an image pickup device, and an observation monitor. The video processor applies, on the basis of a difference between a first image signal having a peak wavelength of a spectral characteristic and a second image signal having a peak wavelength of the spectral characteristic that a value in the absorption characteristic is lower than the value in the absorption characteristic of the first image signal and a scattering characteristic of the living tissue is suppressed more than the scattering characteristic of the first image signal between a wavelength band including a maximum value and a wavelength band at a minimum value in an absorption characteristic of a living tissue, processing for enhancing the first image signal and generates an enhanced and corrected image signal.
