An endoscope system includes a light source device, a CCD, a video processor, and an observation monitor, wherein the video processor includes: a band decomposition processing section that performs a decomposition processing for decomposing into a plurality of spatial frequency bands on a signal of an image picked up by the CCD, to generate a plurality of band images; an enhancement processing section that performs an enhancement processing on selected band images based on an enhancement amount set for a region where an observation target in a subject is distributed in a feature space formed with wavelength bands or spatial frequency bands of the band images selected among the plurality of band images as axes; and an image generation section that integrates the plurality of band images subjected to the color conversion processing, for each wavelength image, to generate an image.
