Title (EN) STEREOSCOPIC ENDOSCOPE
(FR) ENDOSCOPE STÉRÉOSCOPIQUE
(JA) 立体内視鏡
Abstract:
(EN) This stereoscopic endoscope is characterized by: comprising a first objective optical system OBL1, a second objective optical system OBL2, a first imaging element IMG1 having an imaging area which corresponds to the field of view of the first objective optical system OBL1, a second imaging element IMG2 having an imaging area which corresponds to the field of view of the second objective optical system OBL2, and a monitor 101; and satisfying the following condition (1) and condition (2). Condition (1): the proportion between a first value obtained by multiplying the sum of a first distance DT1 and a second distance DT2 by the magnification of the monitor 101 and the vertical dimension T (mm) of the display screen of the monitor is 1.5-10.5% (exclusive). Condition (2): the proportion between a second value obtained by multiplying the difference between a third distance and a fourth distance by the magnification of the monitor 101 and the vertical dimension T of the display screen of the monitor is 1.2-7.5% (exclusive).
(FR) L'invention concerne un endoscope stéréoscopique caractérisé en ce qu'il comprend : un premier système optique d'objectif OBL1, un second système optique d'objectif OBL2, un premier élément d'imagerie IMG1 ayant une zone d'imagerie qui correspond au champ de vision du premier système optique d'objectif OBL1, un second élément d'imagerie IMG2 ayant une zone d'imagerie qui correspond au champ de vision du second système optique d'objectif OBL2, et un moniteur 101 ; et satisfaisant aux conditions (1) et (2) suivantes. Condition (1) : la proportion entre une première valeur obtenue en multipliant la somme d'une première distance DT1 et d'une seconde distance DT2 par le grossissement du moniteur 101 et la dimension verticale T (mm) de l'écran d'affichage du moniteur est de 1,5-10,5 % (ces valeurs étant excluses). Condition (2) : la proportion entre une deuxième valeur obtenue en multipliant la différence entre une troisième distance et une quatrième distance par le grossissement du moniteur 101 et la dimension verticale T de l'écran d'affichage du moniteur est de 1,2-7,5 % (ces valeurs étant excluses).
(JA) 第1の対物光学系OBL1と、第2の対物光学系OBL2と、第1の対物光学系OBL1の視野範囲に対応する撮像範囲を有する第1の撮像素子IMG1と、第2の対物光学系OBL2の視野範囲に対応する撮像範囲を有する第2の撮像素子IMG2と、モニター101と、からなり、以下の条件(1)及び条件(2)を満たすことを特徴とする。 条件(1)は、第1距離DT1と第2距離DT2との和に、モニター101の倍率を乗算した第1の値と、モニターの表示画面の縦の大きさT(mm)との割合が、1.5%より大きく、10.5%より小さいこと、 条件(2)は、第3距離と第4距離との差分に、モニター101の倍率を乗算した第2の値と、モニターの表示画面の縦の大きさTとの割合が、1.2%より大きく、7.5%より小さいこと、 である。
