Abstract
An endoscope system includes: an endoscope equipped with an insertion portion, and an image pickup unit disposed at a distal end portion of the insertion portion; an illumination unit detachably connected to the endoscope; an imaging mode input unit used to set an imaging mode of the endoscope to one of a normal-light mode and a special-light mode; a processing condition selection unit which selects a processing condition for a color correction process of an endoscopic image based on the imaging mode; and a processor detachably connected to the endoscope and equipped with an image processing unit which performs the color correction process, under the processing condition selected by the processing condition selection unit, with respect to each of hue regions partitioned by at least eight reference color axes including six reference color axes which divide a color space into R (red), M (magenta), B (blue), C (cyan), G (green), and Y (yellow) hue regions and at least two reference color axes established additionally based on the imaging mode.
