摘要：
An endoscope device comprises: an illumination means for, within a prescribed time, carrying out an illumination by an illumination light of a first band, and carrying out an illumination by a an illumination light of a second band over a first number of iterations which is greater than one； a brightness computation means for computing a first brightness by a color conversion matrix process which uses a first image capture signal on the basis of the illumination by the illumination light of the first band and a second image capture signal on the basis of the illumination of a first prescribed iteration among the first number of iterations, and for computing a second brightness by a color conversion matrix process which uses the first image capture signal on the basis of the illumination by the illumination light of the first band and a second image capture signal on the basis of the illumination of other than the first prescribed iteration among the first number of iterations； and a compositing means for multiplying the first and second image capture signals which are the basis of the second brightness by a coefficient based on the ratio of the second brightness to the difference of the first brightness and a target brightness, and thereafter compositing same with the first and second image capture signals which are the basis of the first brightness.La présente invention concerne un dispositif d'endoscope comprenant les éléments suivants : un moyen d'éclairage destiné à éclairer une première bande avec une lumière d'éclairage pendant un temps prescrit, et à éclairer une seconde bande avec une lumière d'éclairage pendant un premier nombre d'itérations supérieur à un ； un moyen de calcul d'intensité, destiné à calculer une première intensité par un processus de conversion de matrice de couleur ‑ qui utilise un premier signal de capture d'image sur la base de l'éclairage de la première bande avec la lumière d'éclairage, et un second signal de capture d'image sur la bas
