    • An endoscope system where, when an endoscope with a normal view angle and an endoscope with a wide view angle are used, the difference in brightness of images from the endoscopes displayed on monitor screens is reduced so that the endoscope has a high observation ability. The endoscope system has a first endoscope having a first observation optical system with a first view angle and having a first illumination optical system, and has a second endoscope having a second observation optical system with a second view angle greater than the first view angle. At an arbitrary distance from the head of an insertion section of each of the first endoscope and the second endoscope to the direction of observation, a second irradiation range of illumination light, having a predetermined illumination intensity, irradiated by the second endoscope is greater than a first irradiation range, having the predetermined illumination intensity, irradiated by the first illumination optical system. ® KIPO & WIPO 2007
    • 一种内窥镜系统,其中,当使用具有普通视角的内窥镜和具有宽视角的内窥镜时,减少了显示在监视器屏幕上的内窥镜的图像的亮度差,使得内窥镜具有高的观察能力。 所述内窥镜系统具有具有第一观察角度的第一观察光学系统和具有第一照明光学系统的第一内窥镜,具有第二观察光学系统,所述第二观察光学系统的第二视野角大于所述第一视野角。 在与第一内窥镜和第二内窥镜的插入部的头部至观察方向的任意距离处,由第二内窥镜照射的具有规定的照明强度的照明光的第二照射范围大于 具有由第一照明光学系统照射的预定照明强度的第一照射范围。 ®KIPO&WIPO 2007
