Abstract
(EN) Provided is an endoscope system that comprises a processor and that displays a biological substance feature amount distribution image obtained from a captured image of biological tissue. The processor uses color image data components of biological tissue illuminated by at least two light beams to calculate biological substance feature amounts of the biological tissue, such as the amount of hemoglobin and the oxygen saturation level of the hemoglobin, generates a feature amount distribution image indicating the distribution of the biological substance feature amounts, and controls the display of the feature amount distribution image in order to display the generated feature amount distribution image overlaid onto the image of the biological tissue. The processor extracts, from the biological substance feature amount distribution, an image of an unhealthy section distribution indicating the distribution of a plurality of different feature amount ranges. An image display device displays each extracted distribution image so that the images are overlaid onto the biological tissue image and are identifiable.
(FR) La présente invention concerne un système endoscope qui comprend un processeur et qui affiche une image de distribution de quantité de caractéristique de substance biologique à partir d’une image capturée de tissu biologique. Le processeur utilise des composantes de données d’image de couleur de tissu biologique éclairé par au moins deux faisceaux de lumière pour calculer les quantités de caractéristique de substance biologique du tissu biologique, de sorte que la quantité d’hémoglobine et le niveau de saturation d’oxygène de l’hémoglobine, génère une image de distribution de quantité de caractéristique indiquant la distribution des quantités de caractéristique de substance biologique, et commande l’affichage de l’image de distribution de quantité de caractéristique afin d’afficher l’image de distribution de quantité de caractéristique générée superposée sur l’image du tissu biologique. Le processeur extrait, à partir de la distribution de quantité de caractéristique de substance biologique, une image d’une distribution de section non saine indiquant la distribution d’une pluralité de différentes plages de quantités de caractéristique. Un dispositif d’affichage d’image affiche chaque image de distribution extraite de sorte que les images sont superposées sur l’image du tissue biologique et sont identifiables.
(JA) 内視鏡システムは、プロセッサを備え、生体組織の撮像画像から求められる生体物質特徴量の分布画像を表示する。前記プロセッサは、少なくとも2つの光で照明された生体組織のカラー画像データの成分を用いて、前記生体組織における生体物質特徴量、例えばヘモグロビンの量及び前記ヘモグロビンの酸素飽和度を算出し、前記生体物質特徴量の分布を示す特徴量分布画像を生成し、生成した前記特徴量分布画像を前記生体組織の像に重ねて表示するために、前記特徴量分布画像の表示を制御する。このとき、前記プロセッサは、前記生体物質特徴量の分布から、複数の異なる特徴量範囲の分布を示す非健常部の分布の画像を取り出す。画像表示装置は、取り出した各分布の画像を前記生体組織の像に重ねて識別可能に表示する。
