Abstract: Broadband light and narrowband light are simultaneously projected toward a subject. The subject is imaged by a color CCD to obtain a blue signal, a green signal, and a green signal. A base image is generated from the signals of three colors. Based on a luminance ratio B/G between the blue signal and the red signal, a B/G image is generated. A high frequency component is extracted from the B/G image to obtain a superficial-blood-vessel extracted image, and a medium frequency component is extracted from the B/G image to obtain a middle-deep-blood-vessel extracted image. Based on the base image and one of the superficial-blood-vessel extracted image and the middle-deep-blood-vessel extracted image, a blood vessel emphasized/de-emphasized image, in which the superficial blood vessels or the middle-deep blood vessels are emphasized or de-emphasized, is generated. The blood vessel emphasized/de-emphasized image is displayed on a monitor.

Abstract: Illumination light projected into a body cavity includes first to third narrowband rays of different wavelength ranges, at least one of these narrowband rays has a central wavelength of not more than 450 nm. Under these narrowband rays, first to third narrowband image signals are respectively obtained through an endoscope.

Abstract: Image capture is performed while broadband and narrow band light are simultaneously emitted to tissue site. B pixel sensing the narrow band light outputs a summed image signal having a brightness value of a B component of the broadband light and a brightness value of the narrow band light. G and R pixels, not sensing the narrow band light, output broadband image signals having brightness values of G and R components of the broadband light, respectively. Based on correlation information and the G component of the broadband light, the brightness value of the B component of the broadband light is obtained. The obtained brightness value is subtracted from the summed image signal to separate the brightness value of the narrow band light therefrom. A broadband image and a narrow band image are generated from the broadband image signals and the narrow band image signal, respectively.

Abstract: An image of a tissue site including a blood vessel is captured while broadband light and narrow band light are emitted to a body cavity. Thereby, broadband image data corresponding to the broadband light and narrow band image data corresponding to the narrow band light are obtained. Picture elements in the same positions are identified between the broadband image and the narrow band image to obtain a brightness ratio LM therebetween. Based on depth correlation information between the brightness ratio and blood vessel depth, a blood vessel depth D corresponding to the brightness ratio is obtained to determine whether each picture element includes a blood vessel and whether the blood vessel depth D is at the surface. Based on the determination, a surface blood vessel region is extracted. A broadband image having the surface blood vessel region with the reduced contrast is generated.
