Abstract: An optical device includes a light source unit and a body unit. The light source unit includes a first light source configured to emit first irradiation light, a second light source configured to emit second irradiation light, a light source control unit, and a light collecting unit. The body unit includes an insertion section. The insertion section includes a light guide member, an optical system, an optical filter, a first imager configured to output image information of a subject, and a second imager configured to output distance information from the optical system to the subject. In the second irradiation light, light intensity is temporally modulated, and the first irradiation light and the second irradiation light are emanated from the insertion section. First measurement light includes light in the same wavelength band as a part of the wavelength band of the first irradiation light, and second measurement light includes light in the same wavelength band as the wavelength band of the second irradiation light, and error information included in the distance information is reduced.

Abstract: An endoscope apparatus includes an illumination apparatus that applies first and second narrow-band light having different peak wavelengths to a subject, an imaging device that acquires image light from the subject with pixels to generate an acquisition image signal, and an image processing circuit. The image processing circuit includes a storage that has stored assumed subject types including information about a wavelength range of assumed subjects, and a subject type decision circuit that decides an assumed subject type for part of the pixels based on a first image signal about the first narrow-band light, a second image signal about the second narrow-band light, and the assumed subject types. The image processing circuit constructs a display image signal based on the acquisition image signal and decided assumed subject type.

Abstract: The endoscope apparatus includes a light exit that radiates an illumination light constituted by narrow-band lights to an observation target, an image sensor that detects a reflected/scattered light from the observation target to output an imaging signal, and an image processing circuit that processes the imaging signal. The image processing circuit includes an estimator that associates, regarding each color sensitivity region of the image sensor, a peak wavelength of the narrow-band light with the intensity of the reflected/scattered light to derive narrow-band light spectral intensity information, estimating wavelength lacking region spectral intensity information, and a processor that performs wavelength lacking region correction processing on the basis of the narrow-band light spectral intensity information and the wavelength lacking region spectral intensity information so that the image signal will be closer to an image signal obtained when an illumination light having no wavelength lacking regions is applied.

Abstract: An endoscope system includes an illumination section, a color component ratio measurement section and a light quantity ratio adjustment circuit. The illumination section including a light source sequentially or simultaneously radiates an illumination light being a plurality of narrow-band lights having wavelengths different from each other and having light quantities which are independently controllable each other, on an observation object. The color component ratio measurement section measures a color component ratio of the illumination light. The light quantity ratio adjustment circuit adjusts a light quantity ratio of the narrow-band lights based on an output from the color component ratio measurement section and performs color correction to cause the illumination light to be a desired color.
