Abstract: Only irregularities on the body tissue, such as a superficial microstructure or a hypertrophy, are made clear. A blue signal B, a green signal G, and a red signal R are obtained by imaging a subject illuminated with white light W using a color CCD 44. Based on these signals B, G, and R, a brightness signal I ((B+G+R)/3) showing the average brightness of the subject is generated. A pixel region exceeding the fixed threshold value Th1 of the brightness signal I is extracted as a superficial microstructure P, such as a pit pattern. A superficial microstructure image 70 obtained by extracting the superficial microstructure P is displayed on a monitor 14.

Abstract: A fluorescent type of green light source of a semiconductor in a light source apparatus for an endoscope includes a blue excitation light source device and green emitting phosphor. The blue excitation light source device emits blue excitation light. The green emitting phosphor is excited by the blue excitation light, and emits green fluorescence. A dichroic filter in a dichroic mirror cuts off the blue excitation light from an emission spectrum of mixed light of the blue excitation light and green fluorescence from the fluorescent type of green light source. Thus, illumination light with the emission spectrum of a target can be stably supplied without influence of the blue excitation light to a light amount of blue light from a blue light source of a semiconductor.

Abstract: A band limiter comprises an optical filter, which has first and second filter sections, and a filter moving mechanism for moving the optical filter. The first filter section reduces intensity of blue light, which is emitted from a B-LED, in a wavelength range of greater than or equal to a peak wavelength of the blue light to generate first blue light. The second filter section reduces intensity of the blue light in a wavelength range of less than or equal to the peak wavelength of the blue light to generate second blue light. A light source controller places the first filter section in a light path of the blue light in a normal mode to generate the first blue light, and places the second filter section in the light path of the blue light in an oxygen saturation mode to generate the second blue light.

Abstract: A blue signal B, a green signal G, and a red signal R are obtained by imagining a subject illuminated with white light W using a color CCD 44. Based on these signals B, G, and R, a normal light image in which a wavelength component of a visible light region is included is generated. Based on the signals B, G, and R, a brightness signal I ((B+G+R)/3) showing the average brightness of the subject is generated. A pixel region exceeding the fixed threshold value Th1 of the brightness signal I is extracted as a superficial microstructure P, such as a pit pattern. A microstructure enhancement image 72 is generated by combining the normal light image with a superficial microstructure image 70 obtained by extracting the superficial microstructure P. The generated microstructure and blood vessel enhancement image 72 is displayed on a monitor 14.

Abstract: An endoscope system includes an endoscope and a processor device. The processor device functions as an abnormality detection unit, an abnormality information generation unit, and an abnormality information management unit. The abnormality detection unit detects an abnormality of the endoscope by using information detected by an image sensor of the endoscope. The abnormality information generation unit generates abnormality information including sensor information detected by the image sensor at a time of abnormality detection and in a predetermined period before and after the abnormality detection and operating information of the endoscope. The abnormality information management unit stores the abnormality information in a memory.
