摘要： An endoscope light source device includes a light source device and a light source controller. A first light and a second light are narrow band light in a blue region. A third light is in a green region. A fourth light is in a red region. A first light amount ratio is a ratio of a sum of the light amounts of the first light and the second light, the light amount of the third light, and the light amount of the fourth light. A second light amount ratio is a light amount ratio of the first light and the second light. The light source controller adjusts the light amount ratio of the first light and the second light to achieve the second light amount ratio so as to adjust the color representation from a yellow region to a red region in an image of an object.

摘要： An endoscope apparatus includes: an imaging device; a light source device; a first processing circuit; and a second processing circuit. The light source device can emit first light and fourth light having peak wavelengths in a transmission wavelength band of the blue color filter, second light, and third light and fifth light having peak wavelengths in a transmission wavelength band of the red color filter. The light source device emits the third light in a first imaging frame and the fifth light in a second imaging frame. The first processing circuit generates a display image based on any one of a first image group including images corresponding to the third light and the fifth light and a second image group including an image corresponding to the fourth light, and outputs a remaining one of the first image group and the second image group to the second processing circuit.

摘要： An illuminating device includes: a semiconductor light source; a temperature control unit disposed on the light source for controlling a temperature of the light source to a desired temperature; a dew condensation determination unit for determining whether dew condensation may occur based on at least a temperature associated with the illuminating device and an ambient environment condition of the illuminating device; and a temperature control mode selection control unit for selecting, as a temperature control mode of the temperature control unit, a dew condensation suppression mode in which the temperature control unit has a temperature higher than a predetermined temperature and equal to or less than an upper limit of a usable temperature of the light source, based on priority items of operational control of the illuminating device and characteristics of the light source, to temperature-control the temperature control unit, when the determination unit determines that dew condensation may occur.

摘要： An endoscope includes an illuminator to emit illumination light comprised by narrow band lights different in wavelength from an end portion of the endoscope and an imager to image an observation object illuminated by the illumination light emitted from the illuminator. The illuminator includes a light quantity output adjuster to independently control the light quantity of each of the narrow band lights. The endoscope allows observation in three types of modes of a white light mode, a special light mode, and a hybrid mode. A spectral pattern of illumination light in the hybrid mode includes at least a part of a color region of a narrow band light included in the special light mode and is different from either of a spectral pattern of illumination light in the white light mode and a spectral pattern of illumination light in the special light mode.

摘要： 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.
