Title:
ELECTRONIC ENDOSCOPE DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/172156
Kind Code:
A1
Abstract:
This electronic endoscope device is provided with: a spectral image capturing means for capturing a spectral image of a predetermined wavelength region in a body cavity and obtaining spectral image data; a spectral resolving means whereby the spectral data of each of the pixels included in the spectral image data is resolved into a predetermined plurality of component spectra by regression analysis; a spectral compositing means for re-compositing the predetermined plurality of component spectra, excluding at least one of the plurality of component spectra, and thereby generating composited image data; and a displaying means for performing screen display on the basis of the composited image data.
