Embodiment Construction

[0024] Such as figure 1 As shown, the special light endoscope device 200 of this embodiment has: a light source device 70 that generates and outputs illumination light; The image of the object to be observed is captured by observing the object to generate and output an image signal of the image; the image processing device 90 processes the image signal from the insertion part 80 to generate an image; the monitor 100 displays the image generated by the image processing device 90 ; and an input unit 110 that accepts input operations.

[0025] The insertion unit 80 is detachably connected to the light source device 70 and the image processing device 90 via the connector 22 and the connector 52 .

[0026] The light source device 70 has: a narrow-band light source unit 10A, which has a red chromaticity; a narrow-band light source unit 10B, which has a green chromaticity; a narrow-band light source unit 10C, which has a blue chromaticity; a narrow-band light source unit 10D, which ...

Abstract

This endoscope device is provided with: an illumination means that emits, from the distal end part of the endoscope, illumination light formed of a plurality of narrow bandwidth lights of different wavelengths; and an imaging means that takes an image of an observation subject illuminated by the illumination light emitted from the illumination means. The illumination means has a light amount output adjusting means that controls light amounts of the plurality of narrow bandwidth lights independently. The endoscope device can be used to observe the observation subject in three modes including awhite light mode, a special light mode, and a hybrid mode. The spectrum pattern of the illumination light in the hybrid mode includes at least a part of a color region of the narrow bandwidth lights in the special light mode, and differs from both the spectrum pattern of the illumination light in the white light mode and the spectrum pattern of the illumination light in the special light mode.

Description

technical field [0001] The present invention relates to special light endoscopic devices. Background technique [0002] Currently, in the observation and identification of lesions with an endoscope, first, rough surface screening observation is performed with white light, and suspected lesions are identified to some extent, and suspicious areas are enlarged and observed with narrow-band light. We carry out detailed observation such as abnormality of blood vessel with special light such as. [0003] In this case, white light and special light are used to switch the illumination light for each scene of rough surface observation and magnified detailed observation. [0004] However, in fact, it is difficult to capture the lesion without errors and reliably only by white light screening as the first step, and thus there are also cases of missed detection.
