Abstract

La présente invention concerne un dispositif d'imagerie, un système d'endoscope, un procédé de commande, et un programme, tels que la qualité d'image lors de la capture d'images mobiles peut être améliorée. La présente invention comprend : une unité de commande d'éclairage (342) qui amène une unité d'éclairage (31) à émettre de la lumière d'éclairage comprenant une bande de longueur d'onde verte soit en une première émission et une troisième émission soit en une deuxième émission et une quatrième émission par ordre chronologique dans une période, une période étant un procédé dans lequel l'unité d'éclairage (31) change quatre fois la lumière d'éclairage; une unité de traitement d'image (32) qui effectue le traitement d'image sur les données d'image produites par une unité d'imagerie (22) afin de produire une image; et une unité de commande d'affichage (343) qui amène l'unité de traitement d'image (32) à délivrer l'image en sortie à une fréquence de trames qui est la moitié de la fréquence de trames d'imagerie à laquelle l'unité d'imagerie (22) effectue l'imagerie d'un sujet.
