  • Publication number: 20200099844
    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.

  • Publication number: 20200099845
    Abstract: An endoscope system of the present invention includes: a first illumination unit that emits first illumination light for imaging two sets of image information about a subject at different depths; a second illumination unit that emits second illumination light having a wide band covering a visible band from a position different from the position of the first illumination light; an imaging unit that images a first illumination image and a second illumination image of the subject that is illuminated with the first illumination light and the second illumination light; a separation processing unit that separates the two sets of image information from the first illumination image; and a separated-image generating unit that generates two separated images by processing the second illumination image using the two sets of image information.
