(JA) 内視鏡装置
Abstract
(EN)
 An endoscopic device (1) is provided with: a light source device (4) that irradiates a subject with at least one illuminating light having a prescribed wavelength band; a CCD (2) that images the light returning from the subject on the basis of the irradiation of the illuminating light from the light source device (4); an image processing unit (101) that, after the imaging by the CCD (2), outputs a first image signal (P1) of a first wavelength band having a spectral characteristic peak wavelength between a wavelength band including the maximum value in the absorption characteristic of the body tissue and a wavelength band at the minimum value; and an observation monitor (5) that displays an image on the basis of the first image signal.
(FR)
L'invention concerne un dispositif endoscopique (1) comportant : un dispositif source de lumière (4) qui expose un sujet à au moins un rayonnement de lumière d'éclairement ayant une bande de longueur d'onde prescrite ; un CCD (2) qui image la lumière revenant du sujet sur la base du rayonnement de la lumière d'éclairement provenant du dispositif source de lumière (4) ; une unité (101) de traitement d'image qui, après l'imagerie par le CCD (2), émet en sortie un premier signal d'image (P1) d'une première bande de longueur d'onde ayant une longueur d'onde de pic caractéristique spectral entre une bande de longueur d'onde comprenant la valeur maximale dans la caractéristique d'absorption du tissu du corps et une bande de longueur d'onde à la valeur minimale ; et un moniteur d'observation (5) qui affiche une image sur la base du premier signal d'image.
(JA)
 内視鏡装置1は、被検体に対し、所定の波長帯域を有する少なくとも1つ以上の照明光を照射する光源装置4と、光源装置4からの照明光の照射に基づく被検体からの戻り光を撮像するCCD2と、CCD2による撮像後、生体組織の吸収特性において極大値を含む波長帯域から極小値における波長帯域の間で、分光特性のピーク波長を有する第1の波長帯域の第1の画像信号P1を出力する画像処理部101と、第1の画像信号に基づき画像表示を行う観察モニタ5と、を備える。
