Abstract
(EN) In order to estimate a non-perfusion area, an image-emphasizing processing unit that performs image-emphasizing processing for emphasizing a blood vessel part of a fundus oculi image of a subject's eye (304). An estimation processing unit estimates the non-perfusion area from the fundus oculi image subjected to image-emphasizing processing (306-312). A generation unit generates a non-perfusion area candidate image (314).
(FR) L'invention concerne, afin d'estimer une zone de non-perfusion, une unité de traitement d'accentuation d'image qui effectue un traitement d'accentuation d'image pour accentuer une partie de vaisseau sanguin d'une image de fond d'œil d'un œil d'un sujet (304). Une unité de traitement d'estimation estime la zone de non-perfusion à partir de l'image de fond d'œil soumise à un traitement d'accentuation d'image (306-312). Une unité de génération génère une image candidate de zone de non-perfusion (314).
(JA) 無灌流領域を推定する。 強調画像処理部が、被検眼の眼底画像に対し、血管部分を強調する強調画像処理を行う(304)。推定処理部が、前記強調画像処理がなされた前記眼底画像から無灌流領域を推定する(306~312)。作成部が、無灌流領域候補画像を作成する(314)。
