Abstract: 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.

Abstract: 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.

Abstract: 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.
