ENDOSCOPE SYSTEM

摘要

An endoscope system has an illuminator configured to illuminate an object to be observed with normal light, an image processor that generates an observed image from one field/frame worth of image-pixel signals. The image-pixel signals is read from an image sensor provided in the tip portion of a video scope, and the image processor generates a plurality of spectral images in accordance to the emission of a plurality of narrow-band light. Furthermore, the endoscope system has a detector that detects an operator's aiming spot with respect to at least the plurality of spectral images, a determiner that determines a diagnosis object area that contains the detected aiming spot, and a spectral image processor that extracts a diseased portion with spectral characteristics different from those of the other portions, among the plurality of diagnosis object areas that are defined within the plurality of spectral images.

1. An endoscope system comprising:
an illuminator configured to illuminate an object to be observed with normal light, said illuminator being capable of emitting a plurality of narrow-band light having different peak wavelengths, respectively; an image processor that generates an observed image from one frame/field worth of image-pixel signals, the image-pixel signals being read from an image sensor provided in the tip portion of a video scope, said image processor generating a plurality of spectral images in accordance to the emission of the plurality of narrow-band light; a detector that detects an operator's aiming spot with respect to at least the plurality of spectral images; a determiner that determines a diagnosis object area that contains the detected aiming spot; and a spectral image processor that extracts a diseased portion with spectral characteristics different from those of the other portions, among the plurality of diagnosis object areas that are defined within the plurality of spectral images, said image processor generating a diagnosis image that distinguishes the diseased portion from the other image portions.
