Abstract: An endoscopic system includes a speckle reduction unit which is reduce speckle generated on an observed portion by light that has coherence, a controller which controls an operation of the speckle reduction unit and a plurality of observation modes including a speckle observation mode of observing the observed portion based on the speckle generated on the observed portion by the light. The controller controls the operation of the speckle reduction unit in accordance with the observation modes such that the speckle reduction unit does not reduce the speckle in the speckle observation mode and the speckle reduction unit reduces the speckle in the observation modes other than the speckle observation mode.

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: A light source device to illuminate a target to be imaged by an imaging unit which includes N kinds of light detection elements which wavelength sensitivity regions are different each other includes a light source section, an insertion portion, an illumination light emitting portion and a light guide member. The light source section emits M kinds of narrow-band light which have different peak wavelengths, a difference between the peak wavelengths being equal to or more than an effective wavelength gap. The insertion portion is configured to be inserted into an internal space of an object. The illumination light emitting portion is provided in the insertion portion and which emits an illumination light. The light guide member guides the narrow-band light emitted from the light source section to the illumination light emitting portion.
