Abstract
An endoscope system according to the present invention includes: an illumination unit that radiates illumination light onto a subject, the illumination light having a spatially non-uniform intensity distribution including a light section and a dark section in a beam cross section orthogonal to an optical axis; an imaging unit that images an illumination image of the subject irradiated with the illumination light; and a separation processor that generates two separate images from the illumination image. Among intensity values of pixels within the illumination image respectively corresponding to the light section, the dark section, and a section having intermediate intensity between the light section and the dark section, the separation processor generates the two separate images based on at least two of the intensity values.
