摘要： An endoscope system includes a processor and displays a distribution image of living substance feature amounts obtained from an imaged image of a living tissue. The processor calculates the living substance feature amount in the living tissue, for example, an amount of hemoglobin and oxygen saturation of the hemoglobin using components of color image data of the living tissue illuminated with at least two lights, generates the feature amount distribution image illustrating a distribution of the living substance feature amounts, and controls display of the feature amount distribution image in order to display the generated feature amount distribution image so as to be superimposed on the image of the living tissue.

摘要： An endoscope system generates first to third color image data by imaging biological tissue illuminated with first to third light. The endoscope system uses a first light intensity ratio of the first light and the second light, and/or an imaging sensitivity of the image sensor, to correct a first ratio between multiple components of the first and second color image data, and the endoscope system calculates a first characteristic amount of the biological tissue based on the first corrected ratio. Furthermore, the endoscope system uses a second light intensity ratio between the second light and the third light to correct a second ratio between multiple components of the second and third color image data, and the endoscope system calculates a second characteristic amount of the biological tissue based on the second corrected ratio and the first characteristic amount.

摘要： An endoscope light source device is constituted by a first light source unit that emits light in a first wavelength band, a second light source unit that emits light in a second wavelength band, a light path combining means for combining the light paths of the light emitted from the first and second light source units, and a light source control means for controlling light emission of the light source units separately. When the light source units are driven to emit light in a first mode, the respective wavelength bands of light are emitted at a first intensity ratio and combined with each other to obtain normal light, which is supplied to an endoscope. Also, when the light source units are driven to emit light in a second mode, the respective wavelength bands of light are emitted at a second intensity ratio having a relatively lower ratio of the light in the second wavelength band, and are combined with each other to obtain special light that has a high light absorption rate in a specific biological tissue, and the special light is supplied to the endoscope.

摘要： A processor of an endoscope system uses components of color image data of biological tissue illuminated by at least two types of light to generate an oxygen saturation distribution image of hemoglobin in the biological tissue and to calculate a certainty of an oxygen saturation. Furthermore, the processor controls a display mode of the oxygen saturation distribution image according to the degree of the certainty. The certainty drops if the value of a first component a of the color image data is lower than a lower limit threshold value. The certainty drops if the value of a second component b of the color image data is greater than an upper limit threshold value. The lower limit threshold value and the upper limit threshold value are values of two different pieces of color image data.

摘要： Provided is an electronic endoscope system including: image signal generation means for sequentially taking images of a subject sequentially irradiated with multiple types of irradiation light having different spectrums and generating image signals of the subject irradiated with the respective types of irradiation light as image signals of multiple systems; storage means having a predetermined correction value stored therein in advance; and spectral image generation means for generating a spectral image based on image signals of at least two systems among the image signals of multiple systems generated by the image signal generation means. When generating the spectral image based on the image signals of the at least two systems, the spectral image generation means corrects an image signal of at least one system among the image signals of the at least two systems based on the correction value stored in advance in the storage means.

摘要： An endoscope system captures images of biological tissue when illuminated with first to third light, and generates first to third color image data. The amount of hemoglobin in the biological tissue and the oxygen saturation of the hemoglobin are calculated using components of the first to third color image data, an oxygen saturation distribution image that shows the distribution of the oxygen saturation is generated, and control is performed such that the generated oxygen saturation distribution image is displayed superimposed on a captured image of the biological tissue on a display. The oxygen saturation is calculated based on the amount of hemoglobin and a second ratio obtained using components of the color image data. The transparency is adjusted for pixels in which the value of the second ratio is outside an allowable range for the second ratio determined according to the amount of hemoglobin.

摘要： An electronic endoscope has a light source configured to emit normal light toward an object and a rotating filter configured to be positioned in the path of light that passes from the light source to an image sensor. The rotating filter has an optical band-pass filter and a ND filter. The electronic endoscope has further a rotation controller that synchronizes a light-path traverse-interval of the band-pass filter and a light-path traverse-interval of the ND filter with a field/frame interval; and an image generator that generates a normal image from broadband image-pixel signals and generates a spectral image from specific-band image-pixel signals. The image generator has a brightness adjuster that increases a brightness level of the spectral image. Then, the ND filter reduces an amount of light emitted from the light source to an amount of light that corresponds to an increased brightness of the spectral image.
